Sage 100 to Acumatica Migration Guide 2026: Complete ERP Modernization Guide

Sage 100 to Acumatica Migration Guide 2026: How to Modernize Your ERP Without Losing Your Business Data

Moving from Sage 100 to Acumatica is not simply a software replacement. It is an opportunity to redesign how finance, inventory, sales, purchasing, manufacturing, projects, warehouses, reporting, integrations, and employees work together.

For many companies, Sage 100 has been a dependable business system for years or even decades. It may contain financial history, customer and vendor records, inventory, sales orders, purchase orders, manufacturing data, custom reports, Crystal Reports, Visual Integrator jobs, ODBC connections, third-party add-ons, SQL databases, and business processes that have gradually become part of the organization’s daily routine.

That history is exactly why a Sage 100 to Acumatica migration should never be approached as a simple export-and-import project.

The business is not only moving accounting data.

It is moving institutional knowledge.

A successful Sage 100 migration to Acumatica must determine:

• which Sage 100 data should move;
• which historical information should remain archived;
• how the chart of accounts should evolve;
• how companies and locations should map into Acumatica;
• how inventory quantities and valuation will be reconciled;
• how open AR and AP documents will be migrated;
• how sales and purchasing transactions will continue after cutover;
• how Sage 100 manufacturing structures should map into Acumatica Manufacturing Edition;
• what happens to Crystal Reports and custom reports;
• how Sage customizations and integrations should be replaced;
• how users will learn the new workflows;
• how the business will continue operating during cutover.

Companies searching for Sage 100 alternative, Sage 100 replacement, Sage 100 cloud ERP migration, Acumatica vs Sage 100, or how to migrate Sage 100 to Acumatica are usually facing the same underlying question:

That is a better question than asking whether Sage 100 is “good” or “bad.”

Sage 100 continues to be an actively supported ERP product. In 2026, Sage released Sage 100 2026 and subsequent product updates with new capabilities and enhancements.

The case for moving to Acumatica is therefore not that Sage 100 has disappeared.

The case is that some growing companies need a different operating model: cloud-native access, broader employee participation, real-time data across locations, open integration architecture, industry-specific ERP functionality, modern dashboards, flexible automation, and a platform designed to connect more of the business in one environment.

Acumatica has also created a dedicated See the Difference Migration Plan for Sage 100 customers, allowing organizations to experience Acumatica using their actual data before committing to a full production conversion.

For BizTech, this migration scenario is particularly relevant.

BizTech Services is both a Sage Certified Gold Development Partner and an Acumatica Gold Partner.

That means our team understands both sides of the transition: the Sage ecosystem a company is leaving and the Acumatica platform it is adopting.

BizTech also develops proprietary Acumatica integrations and enhancements for Amazon, Shopify, WooCommerce, Magento, PayPal, ShipHero, ShipStation, DSCO, CommerceHub, Salesforce, ServiceTitan, EDI, inventory workflows, gift cards, kits, consignment, and custom business systems.

This guide explains the complete migration journey—from the first modernization decision to final data reconciliation and post-go-live support.

Important: Sage 100 Is Still Supported in 2026

One of the easiest ways to damage the credibility of an ERP migration article is to claim that Sage 100 is dead, discontinued, or unsupported.

That is not accurate.

Sage continues to develop and support Sage 100.

Sage 100 2026 introduced enhancements including an AI-powered Help Agent, Global Search, expanded lot and serial number fields, and workflow improvements. Sage subsequently released Sage 100 2026.1 with additional enhancements and fixes.

Sage also continues to position Sage 100 as an ERP solution with accounting automation, payroll, inventory optimization, reporting, workflow capabilities, and integrations.

This matters because a Sage 100 to Acumatica migration should be a strategic choice rather than a fear-based decision.

A business should consider moving because the economics, architecture, integrations, user experience, scalability, remote access, reporting, or operating model no longer fit its needs—not because someone incorrectly claimed the software has disappeared.

This distinction also helps management build a better business case.

The decision becomes:

• What does staying on Sage 100 cost us over the next five years?
• What operational constraints are we accepting?
• How much manual work exists around the ERP?
• How many third-party applications are required?
• How much infrastructure and IT support do we maintain?
• How difficult is it to provide access across locations?
• How quickly can we introduce new channels, warehouses, entities, or business models?
• Would Acumatica create enough measurable value to justify migration?

Those are legitimate ERP questions.

Why Businesses Move Beyond Sage 100

Sage 100 can remain operational long after a company begins experiencing ERP friction.

Financials may still post correctly. Invoices may still be created. Purchase orders may still be entered. Reports may still run.

The first problems often appear around the ERP rather than inside the general ledger.

Examples include:

• employees exporting information to Excel for analysis;
• inventory being tracked in another application;
• different locations operating separate processes;
• warehouse teams depending on paper;
• remote employees relying on additional infrastructure;
• eCommerce orders being synchronized through fragile integrations;
• management waiting for manually assembled reports;
• separate CRM, service, manufacturing, or project applications;
• duplicate entry between Sage 100 and external systems;
• increasing dependence on custom code and specialized knowledge.

Over time, the ERP becomes one component in a larger collection of disconnected tools.

That is when the company should evaluate whether continuing to extend the old architecture remains economically rational.

Growth Across Locations

A company that operated from one office may now have:

• multiple warehouses;
• distribution centers;
• manufacturing facilities;
• field teams;
• remote workers;
• international locations;
• several legal entities.

The ERP architecture must evolve with that structure.

Growing Integration Requirements

Modern businesses increasingly need ERP connected to:

• Amazon;
• Shopify;
• WooCommerce;
• Magento;
• Salesforce;
• payment gateways;
• shipping systems;
• warehouse platforms;
• EDI networks;
• tax services;
• BI tools;
• custom applications.

Integration architecture becomes a strategic ERP capability rather than a secondary technical concern.

More Users Need Direct Information

ERP value increases when decision-makers can access current information directly.

Finance, sales, operations, purchasing, customer service, warehouse teams, production managers, project managers, executives, and field employees may all need different views of the same business data.

Acumatica vs Sage 100 in 2026

The most useful comparison is not a list of checkboxes.

Both products can manage important ERP processes.

The more meaningful question is how each platform supports the future operating model.

The correct decision depends on business requirements.

For companies that are comfortable with Sage 100, have a stable operating model, and do not need major architectural change, remaining on Sage may be perfectly reasonable.

For companies that need a more connected cloud operating environment, Acumatica can offer a stronger long-term platform.

Acumatica’s Official Sage 100 Migration Program

Acumatica has developed a dedicated migration initiative for Sage 100 customers called the See the Difference Migration Plan.

The program is particularly interesting because it reduces one of the biggest barriers in ERP evaluation:

Businesses usually have to imagine what the new ERP will look like using generic demonstration data.

Under this program, Acumatica can instead create an environment using the company’s actual Sage 100 information.

Core Data Migration in Two to Three Days

Acumatica states that its automated process can move core financial information, customer data, vendor data, and open transactions into the evaluation environment in approximately two to three days.

The purpose is to allow the business to see its own data inside Acumatica quickly.

Six-Month Trial Environment

The program includes six months of software access using the company’s migrated information.

This enables users to evaluate:

• navigation;
• financial reporting;
• customer and vendor information;
• open transactions;
• workflows;
• role-based access;
• fit with future requirements.

Guided Migration Support

Acumatica also positions the program around:

• scoping;
• mapping;
• cutover planning;
• scheduled guidance;
• role-based learning.

A Two-to-Three-Day Trial Migration Is Not the Same as a Complete ERP Implementation

This distinction is critical.

The official migration program can create an evaluation environment with core Sage 100 data quickly.

That does not mean every Sage 100 company can completely replace its production ERP in two or three days.

A production implementation may also require:

• business process discovery;
• company and branch design;
• chart of accounts redesign;
• inventory structure;
• warehouse configuration;
• manufacturing setup;
• project or construction configuration;
• historical data strategy;
• custom reports;
• Crystal Reports replacement;
• customization redevelopment;
• eCommerce integrations;
• EDI;
• shipping;
• payment integrations;
• user acceptance testing;
• training;
• final cutover;
• post-go-live support.

The Acumatica migration program is valuable because it lets companies validate the platform using real information before committing to the entire transformation.

That can improve implementation planning because the final scope is based on experience rather than assumptions.

Twelve Signs Your Business May Have Outgrown Sage 100

1. You Depend on Too Many Spreadsheets

If Excel has become the place where inventory, consolidations, project status, forecasts, pricing, or management reports are actually controlled, the ERP is no longer the complete operational system.

2. Employees Enter the Same Data More Than Once

Orders, customers, payments, inventory changes, or shipping information may be copied manually between Sage 100 and external platforms.

3. Several Locations Operate Differently

Different branches may have developed separate spreadsheets, applications, workflows, or reporting routines.

4. Remote Access Requires Additional Complexity

Users need a simpler way to access ERP information from different locations, devices, or working environments.

5. Management Reporting Takes Too Long

If managers wait hours or days while information is exported, consolidated, and reformatted, decision-making is delayed.

6. Inventory Is Not Trusted

Warehouse employees may need to physically verify stock because system quantities do not match operations.

7. Your Business Uses Many Add-On Systems

An expanding stack of inventory, CRM, manufacturing, reporting, EDI, eCommerce, warehouse, and service applications can create integration debt.

8. Adding a New Business Entity Is Difficult

Acquisitions, new divisions, or legal entities may create significant accounting and reporting complexity.

9. Manufacturing Has Outgrown the Current Structure

The company needs stronger planning, scheduling, production management, BOM control, traceability, or shop-floor information.

10. eCommerce and Marketplaces Are Becoming Core Revenue Channels

Amazon, Shopify, WooCommerce, Magento, and retail networks require reliable inventory, order, payment, tax, fulfillment, and refund synchronization.

11. IT Spends Too Much Time Maintaining ERP Infrastructure

The business wants IT resources focused on process improvement and integration rather than servers and legacy dependencies.

12. Technology Is Limiting Business Strategy

The strongest migration signal is when management avoids operational changes because the existing ERP environment makes them too difficult.

What Data Can Be Migrated from Sage 100 to Acumatica?

Most core Sage 100 business data can be migrated.

The exact scope depends on:

• Sage 100 edition;
• version;
• modules;
• data quality;
• custom fields;
• third-party enhancements;
• historical requirements;
• Acumatica target design.

Financial Data

• chart of accounts;
• general ledger balances;
• account history;
• departments or divisions;
• bank accounts;
• currencies;
• financial periods;
• budgets;
• open receivables;
• open payables.

Customers

• customer numbers;
• names;
• addresses;
• contacts;
• terms;
• credit limits;
• salespersons;
• tax information;
• price levels;
• custom fields;
• open balances.

Vendors

• vendor numbers;
• names;
• addresses;
• contacts;
• terms;
• tax identifiers;
• payment information;
• custom fields;
• open balances.

Inventory

• item numbers;
• descriptions;
• product lines;
• units of measure;
• warehouses;
• quantities;
• costs;
• prices;
• lot numbers;
• serial numbers;
• vendor relationships;
• reorder information;
• custom fields.

Sales and Purchasing

• open sales orders;
• open purchase orders;
• quotes where required;
• customer invoices;
• vendor invoices;
• credits;
• payments;
• open commitments.

Manufacturing

Depending on the installed Sage modules and target Acumatica Manufacturing design:

• assemblies;
• bills of material;
• components;
• routing information;
• work centers;
• production-related data;
• inventory relationships;
• manufacturing costs;
• planning data.

Historical Information

Historical migration may include:

• GL transactions;
• invoice history;
• payment history;
• purchasing history;
• sales history;
• inventory history;
• manufacturing history;
• project history.

Assessing the Existing Sage 100 Environment

Before exporting anything, BizTech recommends building a complete inventory of the Sage environment.

Document:

• Sage 100 version;
• Standard, Advanced, or Premium edition;
• installed modules;
• companies;
• divisions;
• warehouses;
• users;
• roles;
• custom fields;
• Visual Integrator jobs;
• Crystal Reports;
• ODBC connections;
• Business Objects customizations;
• third-party modules;
• scheduled tasks;
• imports and exports;
• eCommerce integrations;
• EDI;
• warehouse integrations;
• payment systems;
• reporting tools.

This environment inventory is one reason a migration partner with Sage expertise is valuable.

Source-system knowledge reduces the risk of discovering a critical dependency immediately before cutover.

How Sage 100 Data Is Extracted for Migration

Sage 100 provides several ways to access and export information.

The correct method depends on the edition, module, record type, amount of data, and whether extraction needs to be repeated during test migrations.

Visual Integrator

Sage 100 Visual Integrator can import and export data.

It can be useful for controlled migration extracts because export jobs can define:

• source tables;
• selected fields;
• output file types;
• filters;
• data transformations.

For a migration project, reusable export jobs can be valuable because the same extraction logic can be used during test conversion and final cutover.

ODBC

Sage supports ODBC-based data access.

ODBC can be used with tools such as:

• Microsoft Excel;
• Microsoft Access;
• Crystal Reports;
• SQL tools;
• other ODBC-compatible applications.

ODBC is particularly useful when migration data requires table joins, custom selections, or structured queries.

Report Export

Reports can be exported for migration or, more importantly, reconciliation.

Examples include:

• trial balance;
• AR aging;
• AP aging;
• inventory valuation;
• customer listing;
• vendor listing;
• open sales orders;
• open purchase orders.

Lookup Export

Sage 100 lookups can also be configured and exported to Excel or CSV for selected datasets.

Direct SQL Access Where Applicable

Some Sage 100 environments—particularly Sage 100 Premium and SQL-based deployments—use Microsoft SQL Server databases.

In those environments, migration teams may use SQL-based extraction and database backups as part of the source-data process.

The exact method should be determined according to edition, infrastructure, security, and data ownership.

Sage 100 SQL Data Migration to Acumatica

The phrase Sage 100 SQL migration requires clarification.

Not every Sage 100 environment has the same database architecture.

Sage 100 Premium and certain SQL-based environments can involve Microsoft SQL Server, while other Sage 100 installations use Sage data files with ODBC access.

Therefore, the project should first identify the source architecture.

For SQL-Based Sage 100 Environments

The migration process may include:

• database inventory;
• SQL Server version;
• company databases;
• custom tables;
• third-party schemas;
• database backups;
• ODBC configuration;
• query-based extraction;
• record-count validation;
• data transformation pipelines.

Do Not Treat the SQL Database as the Business Model

Direct access to tables does not automatically explain the business meaning of the data.

The migration team still needs Sage functional knowledge to understand:

• document status;
• relationships;
• control totals;
• open versus historical records;
• posting behavior;
• third-party enhancements.

A technically correct SQL export can still produce a bad ERP migration if the business relationships are misunderstood.

Sage 100 Chart of Accounts Migration

The chart of accounts is one of the areas where companies often copy too much from the old system.

A Sage 100 chart may have evolved over many years.

Accounts may contain embedded information representing:

• departments;
• locations;
• business units;
• product lines;
• entities;
• management reporting conventions.

Acumatica offers account, subaccount, branch, and other reporting structures that may allow the company to simplify the chart.

Migration Tasks

• identify active accounts;
• identify obsolete accounts;
• identify control accounts;
• map retained earnings;
• map cash accounts;
• define branches;
• design subaccount segments;
• map departments or divisions;
• prepare opening balances;
• validate the trial balance.

The objective is not to preserve every account number.

The objective is to preserve financial meaning while improving future reporting.

Migrating Sage 100 Companies, Divisions, and Locations

A growing Sage 100 environment may include:

• multiple company codes;
• separate databases;
• divisions;
• warehouses;
• locations;
• different accounting structures.

Acumatica provides companies, branches, warehouses, and related organizational structures.

The migration should determine which Sage structures represent:

• legal entities;
• financial branches;
• physical locations;
• warehouses;
• reporting dimensions.

These concepts should not be mixed automatically.

Multi-Company Consolidation

For companies running several Sage databases, moving to Acumatica may create an opportunity to centralize:

• financial reporting;
• customer data;
• vendor data;
• inventory visibility;
• intercompany processes;
• security;
• management dashboards.

Sage 100 Customer and Vendor Migration

Customer and vendor master data influences nearly every downstream process.

The migration should address data quality before import.

Customer Information

• customer ID;
• name;
• billing addresses;
• shipping addresses;
• contacts;
• terms;
• credit limits;
• salespersons;
• tax information;
• price level;
• email;
• phone;
• custom fields;
• external integration IDs.

Vendor Information

• vendor ID;
• vendor name;
• addresses;
• contacts;
• payment terms;
• tax information;
• payment details;
• currency;
• custom fields;
• item relationships.

Data Cleansing

Review:

• duplicate accounts;
• inactive customers;
• inactive vendors;
• invalid addresses;
• old contacts;
• duplicate tax IDs;
• inconsistent naming conventions.

Migrating dirty master data simply creates a cleaner-looking interface with the same underlying problems.

Sage 100 Inventory Migration to Acumatica

Inventory conversion is frequently one of the most challenging components of the project.

The business must align:

• item master data;
• warehouse quantities;
• inventory valuation;
• costing methods;
• open purchase orders;
• open sales demand;
• lot and serial information;
• physical inventory.

Item Master

Potentially migrated fields include:

• item number;
• description;
• product line;
• item type;
• units of measure;
• costing information;
• sales prices;
• vendors;
• reorder settings;
• lead times;
• custom fields.

Warehouses

For each warehouse, validate:

• on-hand quantity;
• allocated quantity;
• available quantity;
• inventory value;
• lot balances;
• serial numbers;
• in-transit inventory;
• open supply;
• open demand.

Physical Inventory Reconciliation

The ideal cutover should reconcile:

• Sage 100;
• physical inventory;
• warehouse system;
• eCommerce inventory;
• general ledger inventory accounts.

If those values disagree, the company must determine the authoritative opening balance before Acumatica goes live.

Migrating Open Accounts Receivable and Accounts Payable

Open AR and AP require detailed reconciliation because they directly affect cash and working capital.

Accounts Receivable

Potentially migrated documents include:

• open invoices;
• credit memos;
• unapplied cash;
• customer deposits;
• due dates;
• remaining balances;
• document references.

Accounts Payable

Potential data includes:

• open vendor invoices;
• vendor credits;
• prepayments;
• unapplied payments;
• due dates;
• remaining balances;
• document references.

Required Reconciliation

After migration:

• customer aging should equal approved Sage totals;
• vendor aging should equal approved Sage totals;
• AR should reconcile with the general ledger;
• AP should reconcile with the general ledger;
• unapplied documents should remain traceable.

Sage 100 Sales Order and Purchase Order Migration

Open orders need special attention because they continue through operational workflows after go-live.

Sales Orders

The migration may require:

• customer;
• order number;
• order date;
• customer PO;
• items;
• quantity ordered;
• quantity shipped;
• warehouse;
• price;
• discount;
• tax;
• freight;
• salesperson;
• status;
• channel references.

Purchase Orders

The migration may include:

• vendor;
• PO number;
• items;
• ordered quantity;
• received quantity;
• cost;
• warehouse;
• expected delivery;
• status;
• related receipts.

Partially Completed Documents

Partially shipped or partially received documents should be reviewed individually because source and target systems may represent remaining quantities differently.

Sage 100 Manufacturing and BOM Migration

Manufacturing migrations usually require design rather than simple data conversion.

The source environment may contain:

• assemblies;
• BOMs;
• component relationships;
• routing;
• work centers;
• labor;
• overhead;
• production history;
• inventory requirements;
• planning information.

Acumatica Manufacturing Edition may support:

• bill of material and routing;
• production management;
• material requirements planning;
• planning and scheduling;
• engineering change control;
• product configurator;
• shop-floor workflows;
• manufacturing costing.

Do Not Assume One-to-One BOM Conversion

A source BOM may require changes because:

• units differ;
• routing was handled externally;
• phantom assemblies exist;
• labor was tracked differently;
• overhead rules differ;
• revision control needs improvement;
• planning parameters were stored elsewhere.

The target BOM structure should support future production rather than merely preserve historical Sage behavior.

How Much Sage 100 History Should Be Migrated?

There are several valid strategies.

Full Detailed History

Advantages:

• users remain in one ERP;
• historical research is easier;
• comparative analysis can use one source;
• legacy infrastructure may be retired sooner.

Disadvantages:

• higher migration cost;
• longer reconciliation;
• more transformation;
• increased risk of transferring obsolete data.

Limited History

A company may migrate the current year plus one or more comparative periods.

Summary History

Monthly or annual financial summaries can support comparative reporting without recreating every transaction.

Opening Balances and Open Transactions Only

The cleanest production approach is sometimes to begin with approved opening positions and preserve Sage 100 as a controlled historical archive.

How to Decide

Consider:

• audits;
• tax retention;
• warranty requirements;
• customer service;
• vendor history;
• manufacturing traceability;
• project history;
• comparative reporting;
• cost of maintaining Sage access.

Sage 100 Crystal Reports Migration to Acumatica

Crystal Reports is an important part of many Sage 100 environments.

Companies may have accumulated dozens or hundreds of reports over time.

Common report types include:

• financial reports;
• sales reports;
• inventory reports;
• purchase reports;
• customer statements;
• labels;
• operational forms;
• custom management reports.

These should not automatically be recreated one-for-one.

Inventory Every Report

For each Crystal Report, identify:

• business owner;
• frequency of use;
• data source;
• parameters;
• formulas;
• distribution method;
• whether it is still required.

Possible Acumatica Replacements

A Crystal Report may become:

• an Acumatica report;
• a Generic Inquiry;
• a dashboard;
• a financial report;
• a business event;
• a Power BI or Tableau report;
• an automated notification;
• a report that should simply be retired.

Reporting Migration Is a Redesign Opportunity

A report created fifteen years ago may exist because management could not easily access live data.

If Acumatica can surface that information directly on a role-based dashboard, recreating the old PDF may provide little value.

Migrating Sage 100 Customizations and Business Logic

Many long-term Sage 100 customers use customizations created by Sage partners or internal developers.

They may include:

• Business Objects logic;
• Visual Integrator jobs;
• custom fields;
• scripts;
• modified screens;
• custom reports;
• third-party modules;
• scheduled integrations.

The migration team should not begin by asking:

How do we rewrite this in Acumatica?

The correct first question is:

What business problem does this customization solve?

Possible Target Approaches

The requirement may become:

• standard Acumatica functionality;
• a configuration setting;
• an approval workflow;
• a business event;
• a Generic Inquiry;
• an import/export scenario;
• an API integration;
• a BizTech connector;
• a custom Acumatica customization project.

Migrating Sage 100 Integrations to Acumatica

Many Sage 100 customers do not actually run one ERP.

They run an ecosystem.

That ecosystem may include:

• Amazon;
• Shopify;
• WooCommerce;
• Magento;
• CRM;
• EDI;
• shipping software;
• warehouse systems;
• payment processors;
• tax software;
• manufacturing applications;
• reporting databases;
• custom software.

Every integration must be inventoried before the Sage environment is retired.

Integration Inventory

Document:

• system name;
• business owner;
• technical owner;
• data entities;
• direction;
• frequency;
• authentication;
• record matching;
• error handling;
• monitoring;
• transaction volume.

BizTech Acumatica Connectors

BizTech already develops Acumatica solutions for many common integration scenarios.

• Amazon FBA/FBM Connector;
• Shopify Connector;
• WooCommerce Connector;
• Magento Connector;
• PayPal Integration;
• ShipHero Connector;
• ShipStation Connector;
• DSCO Connector;
• CommerceHub Connector;
• Salesforce Integration;
• ServiceTitan Connector;
• EDI workflows;
• custom API integrations.

Using an existing connector can reduce the amount of custom redevelopment required during migration.

Do Not Rebuild Sage 100 Inside Acumatica

This is one of the most important principles of the entire migration.

Users often request familiar screens, fields, reports, and workflows simply because they know them.

But familiarity does not necessarily mean efficiency.

A stronger migration sequence is:

1. Use standard Acumatica functionality when it fits.
2. Use configuration and low-code tools where possible.
3. Use an existing BizTech or ecosystem solution when one already solves the problem.
4. Keep specialized external software when it genuinely adds value.
5. Develop custom Acumatica functionality only when necessary.

This approach can reduce:

• technical debt;
• custom development cost;
• upgrade risk;
• support requirements;
• implementation time;
• training complexity.

Actual customer examples provide useful evidence of what organizations have achieved after moving from Sage 100 to Acumatica.

These are specific company results, not universal guarantees.

Erickson International

Erickson International replaced Sage 100 and disconnected financial systems with Acumatica.

The company gained real-time inventory visibility across locations and reduced infrastructure complexity.

Eastman Music Company

Eastman Music had operated Sage 100 for decades and needed a platform capable of supporting acquisitions and international growth.

Kelly Products

Kelly Products moved from disconnected Sage environments to Acumatica Manufacturing Edition.

Dakota Red Corporation

Dakota Red operated Sage 100, Microsoft Access, and spreadsheets across 12 locations and 15 entities.

Its Acumatica case study reports:

• 15 entities consolidated;
• inventory visibility across 12 locations;
• approximately $1.5–$2 million reduction in inventory;
• expansion of ERP access from approximately 10 to 70 users.

Spohn Associates

Specialty contractor Spohn Associates replaced Sage 100 and multiple other applications with Acumatica Construction Edition.

The published case study reports:

• one platform replacing approximately 10 applications;
• hours saved through automation;
• efficient management of more than 350 projects annually.

Quality Material Handling

Quality Material Handling replaced Sage 100 and paper/spreadsheet processes with Acumatica.

The published case study reports:

• report preparation reduced from hours to minutes;
• five sales-tax reports consolidated into one;
• 82% reduction in month-end close time.

AFF Group

AFF Group moved from an outdated Sage environment to Acumatica Manufacturing Edition.

The published case study reports:

• millions saved in labor costs;
• production doubled with the same staff;
• major reductions in paper-based processes.

Sage 100 to Acumatica Migration for Manufacturing

Manufacturers are one of the strongest migration audiences.

A manufacturing company may need:

• financial management;
• inventory;
• BOMs;
• routing;
• production orders;
• MRP;
• planning and scheduling;
• lot and serial traceability;
• quality workflows;
• shop-floor data;
• warehouse management;
• eCommerce;
• EDI;
• CRM;
• financial reporting.

The migration should connect manufacturing and financial data rather than preserve separate operational silos.

Sage 100 to Acumatica Migration for Distribution

Distribution companies often need stronger connectivity across:

• purchasing;
• inventory;
• warehouses;
• sales orders;
• pricing;
• replenishment;
• shipping;
• returns;
• eCommerce;
• EDI;
• customer service;
• margin reporting.

A modern ERP should allow warehouse, sales, purchasing, finance, and management teams to work from the same data.

Sage 100 to Acumatica Migration for Construction

Construction businesses may require:

• project accounting;
• job costing;
• budgets;
• commitments;
• change orders;
• subcontracts;
• billing;
• retainage;
• field access;
• document management;
• project dashboards.

The migration may therefore involve more than financial balances.

Active project structures and open commitments may need detailed design.

Sage 100 to Acumatica Migration for eCommerce

An eCommerce company may have built a large integration ecosystem around Sage 100.

The target Acumatica architecture may include:

• Shopify;
• WooCommerce;
• Amazon;
• Magento;
• payment systems;
• shipping platforms;
• warehouses;
• 3PLs;
• returns;
• refunds;
• channel profitability.

BizTech’s existing connector portfolio can reduce the amount of integration redevelopment required.

Sage 100 to Acumatica Migration for Multi-Company Businesses

Multi-company organizations need to evaluate:

• company structure;
• branches;
• shared master data;
• intercompany accounting;
• consolidated reporting;
• currencies;
• security;
• warehouses;
• entity-specific integrations.

Eastman Music’s consolidation of 14 companies and Dakota Red’s 15-entity environment demonstrate the scale Acumatica can support in this scenario.

Common Sage 100 to Acumatica Migration Risks

Risk 1: Assuming Sage 100 Is the Same for Every Customer

Standard, Advanced, Premium, custom modules, hosting, SQL environments, and third-party enhancements create different migration requirements.

Risk 2: Exporting Data Before Designing Acumatica

Source data cannot be mapped correctly until the target structure exists.

Risk 3: Ignoring Custom Reports

A business may rely on Crystal Reports that nobody remembered to include in the migration scope.

Risk 4: Missing Visual Integrator Jobs

Automated imports and exports may support critical operations.

Risk 5: Migrating Inaccurate Inventory

Incorrect opening inventory immediately damages trust in the new ERP.

Risk 6: Rebuilding Every Customization

Some old customizations should be replaced with standard Acumatica functionality.

Risk 7: Migrating Too Much History

Full transaction history can significantly increase cost without producing proportional value.

Risk 8: Forgetting Third-Party Integrations

Payments, EDI, eCommerce, warehouses, and reporting systems must be included from the beginning.

Risk 9: Insufficient Testing

Individual screens can work while complete business processes fail.

Risk 10: No Post-Go-Live Support

Production transactions reveal edge cases that test data may not expose.

Final Conclusion: Moving from Sage 100 to Acumatica

Sage 100 remains an actively supported ERP product in 2026.

That makes the migration decision more meaningful—not less.

A company should move because its business has reached a point where a different ERP architecture creates more value.

For some organizations, that point arrives when they need:

• cloud-native access;
• real-time visibility across locations;
• more employees working directly in ERP;
• modern manufacturing functionality;
• construction or project workflows;
• eCommerce and marketplace automation;
• open APIs;
• modern dashboards;
• less dependence on spreadsheets;
• simpler integration architecture;
• better support for acquisitions and multiple companies.

Acumatica provides a modern ERP platform for that next stage.

But successful migration requires more than choosing software.

It requires understanding the existing Sage environment, designing the future Acumatica architecture, cleansing and reconciling data, rebuilding only the customizations that matter, connecting external systems, testing real workflows, training users, and managing cutover carefully.

BizTech is particularly well positioned for this transition because it understands both ecosystems.

That combination allows the migration to be managed as one connected business transformation instead of a handoff between unrelated source-system and target-system vendors.

For organizations searching for:

• Sage 100 to Acumatica Migration;
• Sage 100 Replacement;
• Sage 100 Alternative;
• Acumatica vs Sage 100;

• Sage 100 Data Migration;
• Sage 100 SQL Migration;
• Sage 100 Crystal Reports Migration;

• BizTech Sage 100 Migration;

the correct first step is a structured migration assessment.

Sage 100 contains the history of the business.

Acumatica provides the next ERP platform.

BizTech helps build the path between them.
