Overview
ABRA Gen stores business data across a unified modular schema — customers, vendors, inventory items, sales orders, purchase orders, AR/AP documents, and GL entries — with user-defined fields and analytical cost-centre dimensions. Acumatica represents the same conceptual entities using its own Data Access Class (DAC) architecture: CR.Customer for customers, AP.Vendor for vendors, IN.InventoryItem for stock, SO.SalesOrder for orders, and GL.Batch plus GL.Tran for the general ledger. Acumatica's custom fields use the Usr prefix (UsrFieldName) and live in the same DAC row as system fields. FlitStack AI sequences the migration so master entities load before transaction entities, foreign-key references resolve correctly, and multi-company ABRA Gen configurations map to Acumatica's separate-company or inter-company setup. Workflows, email templates, and automation rules from ABRA Gen have no Acumatica equivalent and must be rebuilt — we export the definitions as a reference document. Our migration uses staged REST API loads with transaction batching, delta-pickup during cutover, and field-level diff before final commit.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a ABRA Gen 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.
ABRA Gen
Customer / Debtor
Acumatica
CR.Customer
1:1ABRA Gen customer records map to Acumatica CR.Customer. Primary address, contact information, and tax ID migrate as fields on the customer. ABRA Gen customer types or categories map to Acumatica Customer Class codes — your admin selects or creates matching class records in Acumatica before migration runs.
ABRA Gen
Vendor / Creditor
Acumatica
AP.Vendor
1:1ABRA Gen vendor records map to Acumatica AP.Vendor. Remit-to address, payment terms, and tax ID move as fields. Vendor classes from ABRA Gen map to Acumatica Vendor Class codes. One ABRA Gen vendor row becomes one Acumatica vendor with one default location — additional ABRA Gen locations migrate as CR.Location records under the same vendor.
ABRA Gen
Inventory Item / Stock Item
Acumatica
IN.InventoryItem
1:1ABRA Gen stock items map to Acumatica IN.InventoryItem. Item code, description, unit of measure, and cost layer data migrate. ABRA Gen item categories map to Acumatica Item Class records — the item class must exist in Acumatica before inventory items load, so FlitStack sequences this load step first in the master-data phase.
ABRA Gen
Sales Order
Acumatica
SO.SalesOrder
1:1ABRA Gen sales orders migrate to Acumatica SO.SalesOrder. Header fields (order number, date, customer reference) and line items (inventory ID, quantity, unit price) map 1:1. Open orders load as active SO.SalesOrder records; completed orders load as historical records linked to the same customer account. Order totals and tax amounts recalculate in Acumatica based on the tax zone assigned to the customer.
ABRA Gen
Purchase Order
Acumatica
PO.PurchaseOrder
1:1ABRA Gen purchase orders map to Acumatica PO.PurchaseOrder. Vendor reference, line items, and expected delivery dates carry over. The Acumatica PO must reference a valid vendor location record — FlitStack resolves this by linking each PO line to the vendor's primary location. Completed ABRA Gen purchase orders load as receipt-linked historical records.
ABRA Gen
AR Invoice
Acumatica
AR.Invoice
1:1ABRA Gen AR invoices map to Acumatica AR.Invoice documents. The document number, invoice date, due date, and line amounts transfer. Acumatica's AR Invoice links to the customer and currency, and applies the tax zone from the customer's class. Partial payments recorded in ABRA Gen become separate Payment applications in Acumatica linked by document reference.
ABRA Gen
AP Bill
Acumatica
AP.APInvoice
1:1ABRA Gen AP bills map to Acumatica AP.APInvoice. The vendor invoice number, bill date, description, and line amounts transfer. FlitStack maps ABRA Gen's bill reference field to the Acumatica External Reference field so the link is traceable. Prepaid ABRA Gen entries become AP.Prepayment documents in Acumatica.
ABRA Gen
GL Account
Acumatica
GL.Account
1:1ABRA Gen chart of accounts entries map to GL.Account records in Acumatica. Account code, name, type (asset, liability, income, expense), and posting settings migrate. ABRA Gen's cost-centre or analytical dimensions map to Acumatica Subaccount (segment) codes — each dimension requires a corresponding segment in Acumatica's chart of accounts structure to be defined before GL data loads.
ABRA Gen
GL Transaction / Journal Entry
Acumatica
GL.Batch + GL.Tran
1:1ABRA Gen journal entries migrate as GL.Batch records containing GL.Tran lines in Acumatica. Each ABRA Gen posting date becomes the batch date; the journal description maps to the batch description field. ABRA Gen's multi-line journal entries split into individual Tran rows linked to the account and subaccount. Only balanced, posted ABRA Gen entries migrate — draft or unposted entries are flagged for manual review.
ABRA Gen
User-Defined Field (UDF)
Acumatica
Custom Field (Usr prefix)
1:1ABRA Gen UDFs require pre-creation in Acumatica with the Usr prefix before any entity data loads. FlitStack audits every ABRA Gen UDF name and data type, then generates the Acumatica custom field definition script for your admin to apply in the target tenant. Pick-list UDFs in ABRA Gen map to Acumatica fixed-list or dynamic data field types; free-text UDFs map to string fields.
ABRA Gen
Analytical Dimension / Cost Centre
Acumatica
Subaccount / Segment Code
1:1ABRA Gen analytical dimensions (cost centres, departments, projects as line attributes) map to Acumatica subaccount segments. Each ABRA Gen dimension value becomes a subaccount code in Acumatica — the subaccount must be active and linked to the appropriate account groups. Value-by-value mapping is required because dimension naming conventions differ between ABRA Gen installations.
ABRA Gen
Company / Legal Entity
Acumatica
Company
1:manyABRA Gen multi-company or multi-branch configurations may split into multiple Acumatica Company records or consolidate into one. FlitStack maps inter-company AR/AP postings to Acumatica inter-company settings based on whether the ABRA Gen branches share customers, vendors, or GL. The mapping decision must be agreed before migration because it affects the chart of accounts segment structure.
ABRA Gen
Currency / Exchange Rate
Acumatica
CM.Currency + Exchange Rate
1:1ABRA Gen currency codes and historical exchange rates migrate to Acumatica CM.Currency and the Exchange Rate table. Active currencies must exist in Acumatica before any transaction loads that references them. ABRA Gen's fixed vs. floating rate settings map to Acumatica's exchange rate upload mechanism.
ABRA Gen
Tax Registration
Acumatica
Tax Zone + Tax Category
1:1ABRA Gen tax registration IDs and tax category assignments map to Acumatica Tax Zone and Tax Category configurations. Customer tax IDs become Tax ID fields on the customer record. ABRA Gen VAT rates map to Acumatica Tax IDs linked to the appropriate tax category — FlitStack validates that all ABRA Gen tax rates have a matching Acumatica tax agency and rate before transaction data loads.
ABRA Gen
Payment / Settlement Record
Acumatica
AR.Payment / AP.Payment
1:1ABRA Gen payment and settlement records map to AR.Payment (customer payments) or AP.Payment (vendor disbursements) in Acumatica. The payment amount, date, and reference number carry over. FlitStack resolves the application link by matching the payment's customer or vendor reference to the migrated document number.

Pair-specific challenges
Migration approach
Audit ABRA Gen database schema and extract entity inventory
FlitStack connects to the ABRA Gen database (direct SQL access or export via ABRA Gen's data extraction tools) to catalogue every table containing active records. We identify all custom fields, analytical dimension definitions, UDF names and data types, and the relationships between master and transaction records. This audit produces the migration plan outline: which entities exist, their record counts, and which require Acumatica custom field pre-creation. The audit also surfaces any ABRA Gen configurations that store document data in non-standard fields, which FlitStack documents before field mapping begins.
Define Acumatica target schema and create custom fields
Before any data loads, your Acumatica admin (or FlitStack) creates the custom fields, subaccounts, customer classes, vendor classes, and item classes required by the migration plan. FlitStack delivers a schema setup script with exact field names, data types, and pick-list values derived from the ABRA Gen UDF audit. Customer and vendor classes are created from Configuration > Customer Classes and Configuration > Vendor Classes. Subaccounts are created for each ABRA Gen cost-centre dimension value. This step gates all subsequent entity loads — migration cannot proceed if the target schema is incomplete.
Load master data in dependency order with foreign-key validation
FlitStack sequences the migration so entities with no dependencies load first, then entities that reference them. The order is: currencies and tax agencies → chart of accounts + subaccounts → customer classes + vendor classes → item classes → customers → vendors → inventory items. Each batch of records is validated against the Acumatica REST API before the next batch starts — if an account code is missing a required subaccount, the record is held and the dependency gap is flagged. This prevents foreign-key errors that would otherwise halt the transaction migration.
Migrate transaction data with field-level diff on a sample slice
A representative slice of 100–500 records spanning sales orders, AR invoices, AP bills, and GL batches runs first. FlitStack generates a field-level comparison report between the ABRA Gen source record and the Acumatica destination record, highlighting any truncated values, unmapped fields, or recalculated totals. Your team reviews the diff and approves the mapping logic before the full run commits. This step catches currency rounding discrepancies, tax zone assignment errors, and subaccount mapping gaps before they affect thousands of records.
Cut over with delta-pickup and full-run reconciliation
The full migration run loads all remaining records. A delta-pickup window — typically 24–48 hours — captures any ABRA Gen records created or modified during the cutover period while your team continues working in ABRA Gen. FlitStack applies the delta records to Acumatica before final reconciliation. Reconciliation compares record counts and financial totals (AR balance, AP balance, GL trial balance) between ABRA Gen and Acumatica. One-click rollback reverts the Acumatica tenant to the pre-migration snapshot if reconciliation fails. Audit logs document every record inserted, updated, or skipped.
Post-migration review and rebuild reference delivery
After reconciliation passes, FlitStack delivers the complete audit log, a reconciliation summary by entity type, and the ABRA Gen workflow definitions exported as plain-language rebuild reference documents for your Acumatica admin. The rebuild reference covers automation rules, email notification triggers, and any scheduled ABRA Gen processes that must be reimplemented in Acumatica Business Events or Automation Schedules. FlitStack does not implement the Acumatica-side automation rebuild, but the documentation makes it straightforward for your consultant or internal admin to complete.
