ShipStation items are connected with Acumatica inventory through the Inventory Details tab on the ShipStation Store screen. The documented controls load local Stock and Non-Stock items, load products from ShipStation, retrieve one ShipStation product by its Stock Keeping Unit, or SKU, and generate missing items locally.
The Biz-Tech Services ShipStation Acumatica Connector also defines what happens when an imported order contains a product that is not present locally. Import Item can create the new record with configured defaults, while other settings can generate a SKU through the ERP numbering sequence. The source does not show a dedicated item cross-reference table or an alias field.
What ShipStation Item Mapping Does in Acumatica
The Biz-Tech Services Acumatica ShipStation Connector uses Inventory Details as the documented item workspace. It can display local Stock and Non-Stock items, display products retrieved from ShipStation, export local items to ShipStation, and generate local items from ShipStation products that do not already exist.
The guide describes item synchronization and creation rather than a manual row that pairs one ShipStation SKU with one Acumatica Inventory ID. Load ShipStation Item by SKU can retrieve the exact external product, but the source does not name the internal key used to determine whether that product matches an existing item.
For order imports, Import Item checks whether the item exists. If it does not, the system can create a new item record. Defaults for Imported Item Type, Item Class, unit of measure, or UOM, and Warehouse ID appear when Import Item is selected. These settings define new-item creation; the guide does not say that they remap an existing product.
Before Mapping ShipStation Items
The ShipStation Store’s Integration Option controls which tabs and item functions are available. For ShipStation-to-Acumatica processing, the visible tabs include General Info, Import Info, Ship Via Cross Reference, Warehouse Cross Reference, and Inventory Details. Inventory Details is not listed for the opposite integration direction in the source.
The Store Code identifies the corresponding ShipStation store. General Info can retrieve connected stores with Get Stores, and Selected identifies the store used to import orders and shipments. Confirm the store and integration direction before reviewing items so that the Inventory Details data belongs to the intended store.
Test Credentials checks the API connection configured through Consumer Key, Consumer Secret, and Base URL Shipstation Credentials. This is a connection test, not an item-mapping validation. The guide does not describe a separate test for SKU matching.
Map ShipStation Items to Acumatica Inventory Items Step by Step
The documentation provides item actions and import settings rather than one formal mapping wizard. The following sequence stays within those documented controls.
1 Open the ShipStation Store and confirm that Integration Option is set to ShipStation to Acumatica
2 Confirm Store Code and the selected ShipStation store in General Info
3 Open Inventory Details and use Load Acumatica Items to display Stock and Non-Stock items
4 Use Load ShipStation Items to retrieve and display products from ShipStation
5 When a specific external item must be reviewed, use Load ShipStation Item by SKU and enter its SKU
6 Use Generate Items in Acumatica from ShipStation when a ShipStation item does not exist locally and should be created
7 If order import should create missing items automatically, select Import Item and set Imported Item Type, Item Class, UOM, and Warehouse ID
8 Decide whether Use Numbering Sequence for SKU Generation should create a new SKU when no existing SKU number is found
9 Import a controlled order and review the resulting line before processing a larger set of orders
How Import Item Handles Missing Products
Import Item defines the documented missing-product behavior during order import. When selected, the system checks whether an item exists in Acumatica and creates a new item record when it does not. The default fields that appear with this option supply the type, class, UOM, and warehouse for the created item.
When Import Item is not selected and a new product is encountered, the guide says the system automatically assigns default values such as Replace Missing Products for the item name and uses the Warehouse ID from setup. It does not explain whether Replace Missing Products is an Inventory ID, description, placeholder record, or another value.
No unmapped-record queue, pending-review status, or exception inquiry is documented. The source also does not say whether several unknown products share the same placeholder, whether an order remains importable, or how a placeholder is replaced with the final inventory item later.
Item Type Item Class UOM and Warehouse Defaults
Imported Item Type, Item Class, UOM, and Warehouse ID appear only when Import Item is selected. They are documented as defaults for creating new items in Acumatica. This is the guide’s only item-class behavior: one configured Item Class can be applied during creation.
The manual does not describe class-specific mapping rules, multiple classes chosen by SKU pattern, or an item-class cross-reference. It also does not define how Imported Item Type affects Stock versus Non-Stock creation or whether the UOM must already exist in Acumatica.
Warehouse ID is a creation and import default in this section. Warehouse Cross Reference is documented separately and maps warehouses between the systems. The source does not state that warehouse cross-references participate in identifying the inventory item itself.
How SKU Generation Works for a Missing Number
Use Numbering Sequence for SKU Generation applies when the system does not find an existing SKU number during item creation. When enabled, it generates a new SKU from the numbering sequence configured in Acumatica. The guide says this produces consistent and unique SKUs for created items.
The source does not identify the numbering sequence screen, field, format, prefix, or next-number behavior. It also does not say what happens to the original ShipStation SKU after a different local SKU is generated or which value is used on later imports.
No rule is provided for blank SKUs, duplicate SKUs, case differences, spaces, leading zeros, or SKU length. Those cases should not be assigned undocumented matching behavior.
Inventory Details Actions for ShipStation Products
The Biz-Tech Services ShipStation Acumatica Integration provides five documented item actions in Inventory Details. Together they load data from either system, export local product data, retrieve one product by SKU, or create missing local items.
Load Acumatica Items retrieves all Stock and Non-Stock items and displays them in a table. Update ShipStation Items from Acumatica exports the listed items to ShipStation so external product data reflects current local information. Load ShipStation Items retrieves external products and displays them locally.
Generate Items in Acumatica from ShipStation creates a local record when an item exists in ShipStation but not locally. Load ShipStation Item by SKU retrieves one specific external product. The guide does not name the table columns, selection checkboxes, generated Inventory ID field, or result status for any action.
Cross References and Alias Coverage
The source documents Cross-Reference Options for warehouses and Ship Via methods. Use Cross Ref for Warehouse reveals the warehouse-mapping tab, and Use Cross Ref for Ship Via reveals the shipping-method-mapping tab. It does not document Use Cross Ref for Item or an item cross-reference tab.
Load ShipStation Item by SKU supplies direct SKU lookup, but the guide does not call that value an alias or describe alternate identifiers. There are no documented customer part numbers, vendor item numbers, universal product codes, external product IDs, or many-to-one alias rules for items.
Because an item cross-reference structure is not shown, the article cannot assign field names or precedence rules to one. Inventory Details and the Import Item creation settings are the documented controls for this topic.
Validation Rules and Item Mapping Gaps
The ShipStation guide does not document an item-validation button, mapped or unmapped status, line-level item error field, duplicate warning, or validation report. Import ShipStation Orders can display an error when a store uses the wrong Integration Option, but that check validates store direction rather than item mapping.
The source also does not state how the system decides that an item exists, what field is compared with the ShipStation SKU, or whether a generated item is Stock or Non-Stock under each Imported Item Type. No behavior is documented for conflicting matches or for an item that exists but is inactive.
A controlled import is therefore the available documented confirmation path. The manual says Get Orders retrieves ShipStation orders and Import sends selected orders to Sales Orders in Acumatica, but it does not list the item fields to inspect on the resulting line.
Where to Check Your ShipStation Item Setup
The Biz-Tech Services ShipStation Acumatica Integrator exposes the following documented places to review store direction, item creation defaults, and inventory actions.
1 On ShipStation Store, confirm Store Code and Integration Option
2 In General Info, use Get Stores and verify that the intended ShipStation store is Selected
3 In Item Information, review Import Item, Imported Item Type, Item Class, UOM, and Warehouse ID
4 Review Use Numbering Sequence for SKU Generation when the product has no existing SKU number
5 In Inventory Details, use Load Acumatica Items to display local Stock and Non-Stock records
6 Use Load ShipStation Items or Load ShipStation Item by SKU to display the external product
7 Use Generate Items in Acumatica from ShipStation only when the missing external product should create a local item
8 On Import ShipStation Orders, retrieve a controlled order and inspect the Sales Order created by Import
ShipStation Item Mapping Frequently Asked Questions
Where can I load ShipStation items for review in Acumatica?
Use Inventory Details on the ShipStation Store configured for ShipStation to Acumatica. Load ShipStation Items retrieves external products and displays them locally.
Can I retrieve one ShipStation product by SKU?
Yes. Load ShipStation Item by SKU retrieves a specific product by its SKU and displays it in Acumatica.
What creates a missing Acumatica inventory item?
The Biz-Tech Services Acumatica ShipStation Integration can create a missing item through Import Item during order import or through Generate Items in Acumatica from ShipStation in Inventory Details. The guide does not explain precedence when both are used.
Which defaults are used when Import Item creates a record?
Imported Item Type, Item Class, UOM, and Warehouse ID appear as defaults when Import Item is selected.
What happens when Import Item is not selected?
For a new product, the guide says default values such as Replace Missing Products are assigned for the item name and the setup Warehouse ID is used. It does not explain the resulting record structure.
Can ShipStation items be mapped through an item cross reference?
The documentation only defines cross-references for warehouses and Ship Via. It does not show an item cross-reference option or tab.
Can different SKUs be treated as aliases for one inventory item?
No alias behavior is documented. Load ShipStation Item by SKU performs a direct lookup, but the guide does not describe many-to-one aliases or alternate item identifiers.
How can I validate an item mapping before importing orders?
The source does not provide an item-mapping validation action. Review the store, creation defaults, and Inventory Details, then use a controlled order import to confirm the resulting line.
Work With Biz Tech Services on ShipStation Item Setup
