Overview
Freespace ERP stores SMB operational data in a flat relational model: customers, vendors, and items with basic custom fields, alongside AR/AP invoices and GL accounts. Acumatica uses a more granular model with BusinessAccount (replacing Customer/Vendor), InventoryItem with valuation methods, separate AR and AP document registers, and a segmented chart of accounts that branches by entity and warehouse. We map Freespace's customers to Acumatica BusinessAccount, vendors to Vendor, and inventory items to InventoryItem with type-aware valuation alignment. Financial documents (invoices, credit memos) land in ARInvoice/APInvoice with their original document dates and reference numbers preserved. Custom extended properties on Freespace records become Acumatica extension fields following the ExtNbrType naming convention. Workflows, approval chains, and automation rules have no Acumatica equivalent and must be rebuilt; we export the source definitions as a rebuild reference. We sequence the migration so accounts and items exist before transactional documents to satisfy Acumatica's referential integrity requirements, run a field-level diff on a representative sample, then execute the full load with a 24-48h delta pickup capturing any records modified during cutover.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Freespace ERP object lands in Acumatica, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Freespace ERP
Customer
Acumatica
BusinessAccount (Customer Class)
1:1Freespace customers map 1:1 to Acumatica BusinessAccount records classified as Customer. Primary billing address and shipping address from Freespace become the default Location on the BusinessAccount. Payment terms and credit limit from Freespace transfer to the BusinessAccount's CreditLimit and PaymentRules fields.
Freespace ERP
Vendor
Acumatica
BusinessAccount (Vendor Class)
1:1Freespace vendors map to Acumatica BusinessAccount records classified as Vendor. Tax registration IDs from Freespace map to the TaxRegistrationID field on the Vendor record. The 1099 vendor flag from Freespace translates to VendorTaxZone settings in Acumatica, where the tax zone determines reporting requirements. Payment terms and remittance addresses also migrate to the corresponding Vendor location fields.
Freespace ERP
Item / Product
Acumatica
InventoryItem
1:1Freespace inventory items map to Acumatica InventoryItem with class-group alignment. Item type (stock vs. non-stock vs. service) maps to the ItemType field. Base unit of measure from Freespace translates to the DefaultVolumeUOM/DefaultWeightUOM on the item. Valuation method selection requires explicit mapping per Freespace item class.
Freespace ERP
GL Account
Acumatica
Account (with Segments)
1:1Freespace flat account codes require segmentation for Acumatica's dimension model. We analyze the Freespace account code pattern and propose a segment split (e.g., branch/department/account) to align with Acumatica's SubCD + Branch structure. Accounts that cannot segment cleanly are flagged for consolidation or sub-account creation.
Freespace ERP
AR Invoice
Acumatica
ARInvoice (ARRegister)
1:1Freespace AR invoices map to Acumatica ARInvoice records preserving the original document date, invoice number, description, and reference Nbr. Line items map to ARTran with inventory ID lookup and tax amount from Freespace redistributed via Acumatica's TaxCategory. Status (open/closed) maps to ARDocumentStatus.
Freespace ERP
AP Invoice
Acumatica
APInvoice (APRegister)
1:1Freespace AP bills map to Acumatica APInvoice records with original vendor reference number and invoice date preserved. Line items map to APTran with account distribution matching the Freespace expense coding. Prepayments and credit memos from Freespace map to APDocument with DocType discriminating between Invoice, CreditMemo, and Prepayment. Vendor-specific payment terms from Freespace transfer to the TermsID field on the APInvoice record.
Freespace ERP
Sales Order
Acumatica
SalesOrder (SOOrder)
1:1Freespace sales orders map to Acumatica SOOrder with order number, date, and customer reference preserved. Line items map to SOLine with warehouse and site assignment from Freespace's default fulfillment location. Freespace shipping terms and carrier info migrate to SOOrder.ShipVia. Order hold status and discount schedules from Freespace translate to corresponding SOOrder fields and SalesPrice records.
Freespace ERP
Purchase Order
Acumatica
PurchaseOrder (POOrder)
1:1Freespace purchase orders map to Acumatica POOrder. Vendor and buyer assignment from Freespace transfers to POOrder.VendorID and POOrder.EmployeeID. When the EmployeeID from Freespace has no match in Acumatica, we create a placeholder employee record or map to a default buyer ID to maintain referential integrity. Expected receipt date and term details from Freespace become the POOrder.ExpectedDate and POOrder.VendorLocation mapping.
Freespace ERP
Contact (on Customer/Vendor)
Acumatica
Contact + BusinessAccountContact
many:1Freespace contact records attached to a customer or vendor merge into two Acumatica records: a Contact record for personal details (name, email, phone) and a BusinessAccountContact junction linking to the BusinessAccount with a specific role (billing, shipping, primary buyer). Multiple Freespace contacts on one account become multiple BusinessAccountContact rows.
Freespace ERP
Custom Fields / Extended Properties
Acumatica
Custom Fields (Usr-prefix)
1:1Freespace stores custom properties as free-form key-value pairs on standard objects. Each Freespace custom property requires a corresponding Acumatica extension field (UsrFieldName) created via the Customization Project editor before migration. Data type from Freespace (text, number, date, boolean) determines the Acumatica field type.
Freespace ERP
Item Pricing / Price List
Acumatica
SalesPrice + InventoryItemABCCode
1:1Freespace price list entries for an item map to Acumatica SalesPrice records keyed by customer class and quantity break. Effective dates from Freespace become the SalesPrice.StartDate/EndDate. Volume discount tiers in Freespace translate to separate SalesPrice rows per quantity tier. Where Freespace uses a specific currency, we apply the appropriate CuryID on the SalesPrice record. Price overrides at the customer level become separate SalesPrice entries linked to that specific BusinessAccount.
Freespace ERP
Warehouse / Location
Acumatica
Warehouse + Location
1:1Freespace warehouse records map directly to Acumatica Warehouse entities with their warehouse ID and description preserved. Each Freespace bin or storage location maps to a Location record under the corresponding Warehouse, with location code and bin code transferred. Default fulfillment warehouse from Freespace becomes the primary SiteID on SalesOrder lines, ensuring orders route to the correct shipping location automatically.
Freespace ERP
Tax Code
Acumatica
TaxZone + TaxCategory
1:1Freespace tax codes map to Acumatica TaxCategory on lines and TaxZone on the BusinessAccount. Tax rate values from Freespace require value-by-value mapping to Acumatica TaxDetail rates because the underlying tax agency and jurisdiction references differ between platforms. We create a tax mapping table during the schema inventory phase, mapping each Freespace tax code to the corresponding Acumatica TaxCategory ID and TaxZone combination.
Freespace ERP
Payment Terms
Acumatica
Terms
1:1Freespace payment terms (Net 30, Net 60, 2/10 Net 30) map directly to Acumatica Terms records where the name and day count match. Custom Freespace terms with unusual day counts require new Terms records created in Acumatica before invoice migration.
Freespace ERP
Item Category / Class
Acumatica
ItemClass + ProductManager
1:1Freespace item categories map to Acumatica ItemClass records for shared attributes including valuation method, posting accounts, and tax category. We create the ItemClass first, defining the default posting accounts for inventory, COGS, and revenue. Freespace's product manager assignment becomes the ProductManagerID on the InventoryItem after the ItemClass is established. Items without a designated product manager in Freespace receive a default ProductManagerID or are flagged for manual assignment post-migration.

Pair-specific challenges
Migration approach
Schema inventory and Acumatica extension field provisioning
FlitStack runs a full schema inventory against the Freespace ERP API, enumerating all custom fields on every standard object. We compare this against your target Acumatica tenant and produce a field creation checklist with exact names, types, and target objects. Your Acumatica admin (or our team) provisions these fields in the staging environment before any data moves. This step also includes account code analysis for segmentation mapping.
Chart of accounts segmentation mapping
We analyze all Freespace GL account codes to detect segment patterns such as branch prefixes, department codes, and account ranges. Ambiguous or non-standard codes are flagged for manual mapping review. We deliver an account segmentation plan mapping each Freespace account code to Acumatica Branch, Department, and Account records. Any new Acumatica dimension values required are created in the target tenant before the account migration step begins.
Data dependency sequencing — master data before transactions
Acumatica enforces referential integrity: BusinessAccounts must exist before AR/AP documents can reference them, InventoryItems must exist before SalesOrder/PurchaseOrder lines can be saved, and Accounts must exist before any GL batch posts. We sequence the migration load in strict dependency order: BusinessAccounts (customers and vendors), InventoryItems, GL Accounts, then transactional documents (AR invoices, AP invoices, sales orders, purchase orders). This prevents the 'orphan record' errors that occur when child records load before parent records.
Sample migration with field-level diff
A representative sample — typically 200–500 records across customer, vendor, item, and invoice types — runs first against the Acumatica staging tenant. We generate a field-level comparison report showing each source value, its mapped destination value, and any transformation applied during mapping. You verify valuation method mapping, account segmentation results, and custom field population on real data. The sample diff must be approved by you before any full migration commits.
Full migration load with delta-pickup window
The full dataset loads into Acumatica using batched API operations. After the initial load window closes, a delta-pickup window (24–48 hours) captures any records created or modified in Freespace during the cutover. All operations are logged in an audit trail. A reconciliation report compares record counts and balance totals between Freespace and Acumatica. One-click rollback is available if reconciliation fails.
