Overview
Aptean SouthWare organizes data across flat files and Microsoft SQL Server tables: Customers, Vendors, Inventory Items, Sales Orders, Purchase Orders, GL Accounts, and Service Orders live in separate file groups that ImportMate can read and write. Acumatica uses a unified SQL database with Customers, Vendors, Stock Items, SO/Purchase Orders, GL Accounts, and Branches as primary entities — each supporting custom fields through Acumatica customization projects. The migration carries every record FlitStack can read from SouthWare's export layer: master records with current balances, transactional history with original posting dates, and attachment references. We surface the chart of accounts, item cost layers, and open order queues in a pre-migration review so your Acumatica admin can configure branches and account structures before data lands. SouthWare workflows, ImportMate import rules, and SQLSync replication logic do not migrate — those require Acumatica business events and import scenarios to be built fresh. The migration mechanism uses Acumatica's REST API with batched record inserts and field-level validation against the target schema.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Aptean SouthWare 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.
Aptean SouthWare
Customer Master
Acumatica
Customer
1:1SouthWare customer records map to Acumatica Customer entities. The Customer Class (residential/commercial) in SouthWare maps to Acumatica's Customer Class picker. Primary contact name, email, phone, and billing address transfer directly. Multi-contact support in Acumatica requires Customer Contacts tab population post-migration.
Aptean SouthWare
Vendor Master
Acumatica
Vendor
1:1SouthWare vendor records map to Acumatica Vendor entities. Payment terms from SouthWare (Net 30, COD) map to Acumatica Terms objects. Remit-to addresses populate the Vendor Locations tab. Tax ID (EIN/VAT) goes into the Tax ID field on the vendor record.
Aptean SouthWare
Inventory Item
Acumatica
Stock Item
1:1SouthWare item records carry description, unit of measure, item class, and cost layer data. The item class controls valuation method (FIFO/average) and maps to Acumatica's Valuation Method field on Stock Items. The primary warehouse/location in SouthWare becomes the default warehouse on the Acumatica item record.
Aptean SouthWare
Sales Order Header
Acumatica
SOInvoice / SOSalesOrder
1:1Open SouthWare sales orders migrate as Acumatica Sales Orders with original order numbers preserved in the Ext. Order Nbr. field. Order date and requested ship date transfer; the assigned sales rep resolves by email match to Acumatica users. Lines migrate with inventory item links and quantities.
Aptean SouthWare
Purchase Order Header
Acumatica
POReceipt / POPurchaseOrder
1:1Open SouthWare purchase orders migrate as Acumatica Purchase Orders with vendor link and expected receipt date preserved. If items have already been partially received in SouthWare, the open balance quantity is calculated and entered into Acumatica at migration time. Multiple line items with mixed receipt statuses transfer with their respective open quantities and unit costs. Purchase order totals reconcile to SouthWare records before closing the migration window.
Aptean SouthWare
GL Account
Acumatica
Account
1:1SouthWare's numeric account codes (e.g., 1100-00) map to Acumatica Account CD values. Acumatica supports structured account codes with segments — if SouthWare uses department or location subcodes, each segment maps to an Acumatica Subaccount dimension. Chart of accounts structure reviewed before migration.
Aptean SouthWare
GL Subaccount / Department
Acumatica
Subaccount
1:1SouthWare departments and cost centers migrate as Acumatica Subaccounts. Subaccount codes and descriptions transfer; the Subaccount Type (e.g., Department, Project) maps to the Subaccount mask in Acumatica's chart of accounts setup. Multiple subaccount levels in SouthWare may require flattening or segment mapping.
Aptean SouthWare
Salesrep / Commission Setup
Acumatica
Salesperson
1:1SouthWare sales rep records map to Acumatica Salespersons. Commission rates and split percentages transfer as Salesperson Commission records linked to each salesperson entity. Email addresses on sales reps in SouthWare are used to match and resolve to corresponding Acumatica user accounts for order ownership assignment and approval routing.
Aptean SouthWare
Service Order / Contract
Acumatica
FSServiceOrder / FSContract
1:1SouthWare service order records and active service contracts migrate to Acumatica Field Service objects. Equipment linked to service orders in SouthWare becomes FSAssets in Acumatica with the same equipment ID and linked customer. Contract billing schedules transfer as FSContractDetail lines with the original contract end date preserved and billing frequency maintained.
Aptean SouthWare
ImportMate Import Rule
Acumatica
Import Scenario
1:1SouthWare ImportMate rules define data import behavior for batch uploads. These have no direct Acumatica equivalent — Acumatica import scenarios perform the same function but require manual rebuild. FlitStack exports ImportMate rule definitions as a reference document for your Acumatica admin.
Aptean SouthWare
SQLSync Configuration
Acumatica
Generic Inquiry / Report
1:1SouthWare SQLSync replicates data to MS-SQL for external reporting and business intelligence connections. Acumatica's Generic Inquiries and Report Designer provide similar reporting capabilities within the platform. Historical transactional data is migrated to Acumatica so standard reports reflect the complete fiscal timeline without external SQL dependencies. External SQL replication setup does not carry forward into the Acumatica environment.
Aptean SouthWare
Attachment / Document Link
Acumatica
Note / File Attachment
1:1SouthWare document attachments associated with customers, vendors, and items migrate as Acumatica Notes attached to the corresponding records. File size limitations apply with a default 25MB per file in Acumatica. Inline images embedded within notes are extracted, downloaded, and rehosted as standalone file attachments on the target record for maximum compatibility.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Aptean SouthWare gotchas
Industry-gated data export formats
Posted vs. unposted transaction states control migration validity
Pre-closed fiscal years lock GL history
Custom Objects discovered only during data profiling
Attachment files live outside the database
Acumatica gotchas
API user licenses cap concurrent sessions and request throughput
Multi-tenant filtering requires CompanyID awareness
Custom fields require separate discovery before field mapping
Notes and attachments use a separate linked table structure
Implementation timelines frequently run 3–9 months end-to-end
Pair-specific challenges
Migration approach
Pre-migration discovery and account structure design
We extract the SouthWare chart of accounts, item class list, warehouse locations, and open order queue as structured CSV files. Your Acumatica admin reviews the account structure and creates Branches, Account Classes, Customer Classes, and subaccount masks before any records move. We deliver a target schema plan covering every object that will receive data, with field-level mapping validated against Acumatica's API schema. This step prevents account code collision and ensures branch assignments are ready before migration records are written.
Export SouthWare master records and transactional data
We pull all master records from SouthWare — Customers, Vendors, Stock Items, Salespersons, and GL Accounts — using the platform's native export tools and SQLSync table reads where applicable. Open sales orders and purchase orders export with full line detail. We generate an audit count of each record type and surface duplicates, missing addresses, and null required fields before mapping begins. This data freeze snapshot is the source of truth for the migration run.
Run sample migration with field-level diff
A representative slice of records — typically 200–500 across customers, items, and open orders — migrates first using Acumatica's REST API with batched inserts of 200 records per call. We generate a field-level diff report comparing source values to destination field contents for every migrated record. Your team reviews the diff to confirm account mapping, customer class routing, item valuation method assignment, and salesperson ownership resolution. We iterate mapping rules based on feedback before the full run commits.
Full migration run with delta-pickup window
All remaining records migrate via the validated mapping pipeline. Acumatica Migration Mode is enabled before GL opening balances and AP/AR records post. After the primary migration window closes, a delta-pickup window (typically 24–48 hours) captures any records created or modified in SouthWare during the cutover period. All operations are logged to an audit trail; one-click rollback reverts the Acumatica tenant to the pre-migration state if reconciliation reveals data quality issues.
Reconciliation validation and Acumatica admin handoff
We run reconciliation checks comparing SouthWare account totals to Acumatica account balances, customer open order counts to SO order totals, and item on-hand quantities to Acumatica Inventory Summary by branch. Any discrepancies are flagged with record-level detail. We hand off a migration summary document, an exported WorkFlow and ImportMate reference guide, and a list of open items requiring Acumatica configuration (import scenarios, business events, report templates). Migration Mode is turned off after your accountant approves the opening balances.
