Overview
WINLine is a mesonic ERP built for small-to-mid-sized businesses with perpetual desktop licensing, covering financial management, CRM, inventory, and manufacturing. It stores customers, vendors, and items as flat records with custom properties appended directly to each entity. Acumatica Cloud ERP is a cloud-native platform using a relational data model where contacts and locations are sub-records of Business Accounts, and inventory items are classified by Item Class and Stock/Non-Stock type. Acumatica requires custom fields to be pre-created in the UI before data can be imported — this shapes every migration plan. We map WINLine customers to Acumatica Business Accounts with their primary Contact and default CustomerLocation. Vendors map to the Vendor entity with its Contact and VendorLocation. Inventory items map to Stock Items with their ItemClass assignment. GL accounts map directly to Chart of Accounts entries. Custom properties on any WINLine entity require us to define the corresponding Acumatica custom field first, then populate it during data load via the Import by Configuration scenario or direct API. Workflows, automated sequences, report definitions, and Saved Search configurations do not migrate — they must be rebuilt in Acumatica's automation and reporting tools. We export WINLine workflow definitions as a rebuild reference during the discovery phase. The migration uses Acumatica's REST API with bulk ingestion for large record sets, AUDIT logging for traceability, and a delta-pickup window to capture in-flight changes during cutover.

Object mapping
Each row shows how a WINLine 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.
WINLine
Customer
Acumatica
Business Account (BAccount)
1:1WINLine customers map 1:1 to Acumatica Business Accounts. The primary contact from WINLine becomes the default Contact sub-record; the primary billing address becomes the default CustomerLocation. All WINLine custom properties on the customer require pre-created Acumatica custom fields before the BAccount import runs.
WINLine
Customer Contact
Acumatica
Contact (sub-record of BAccount)
1:1WINLine contact details (name, email, phone, job title) migrate as Contact sub-records under the BAccount. Each WINLine customer may have multiple contacts; we preserve the primary contact flag and map contact roles to the Contact's ClassID field. Email and phone map directly; no transformation required.
WINLine
Vendor
Acumatica
Vendor (BAccount with VendorClass)
1:1WINLine vendors map to Acumatica Vendors (Business Accounts with a VendorClass). The primary AP contact and default VendorLocation migrate as Contact and VendorLocation sub-records. WINLine vendor tax IDs map to Acumatica's Tax Registration ID field on the Vendor. We also assign a VendorClass to each vendor based on WINLine vendor categories or terms, which controls default payment settings and GL posting accounts in Acumatica.
WINLine
GL Account
Acumatica
Account (Chart of Accounts)
1:1WINLine GL accounts map to Acumatica Chart of Accounts entries. Account type (Asset, Liability, Income, Expense) maps to Acumatica's Account Type pick-list. Subaccount segments in WINLine map to Acumatica's Subaccount dimension if WinLine uses segment-based accounting — each segment becomes a separate Sub segment in Acumatica.
WINLine
Inventory Item
Acumatica
Stock Item (or Non-Stock Item)
1:1WINLine items map to Acumatica Stock Items or Non-Stock Items based on WINLine's Item Type. The WINLine Item Class maps to Acumatica's ItemClass entity, which controls posting settings and inventory tracking. Items flagged as Stock in WINLine land as Stock Items with inventory tracking enabled; Service and Expense items land as Non-Stock Items.
WINLine
Item Warehouse
Acumatica
Warehouse Location + Item Warehouse (INLocation / INItemWarehouse)
many:1WINLine stores per-warehouse item quantities and locations. Acumatica separates these into INLocation (physical warehouse/bin structure) and INItemWarehouse (per-item per-warehouse On Hand, Reorder Point, and Lead Time). We merge WINLine's warehouse-level item data into both entities — warehouse codes map to Acumatica Branch/Warehouse.
WINLine
Sales Order
Acumatica
Sales Order (SO301000)
1:1WINLine sales orders map to Acumatica Sales Orders. Order number, date, customer reference, line items, quantities, and unit prices map directly. Order status (Open, Completed, Cancelled) maps to Acumatica's Status field. WINLine'sfreight and discount amounts map to separate detail lines or the CuryExtPriceCuryID fields on each line.
WINLine
Purchase Order
Acumatica
Purchase Order (PO301000)
1:1WINLine purchase orders map to Acumatica Purchase Orders. Vendor reference, line items, quantities, and landed costs carry over. POLineType maps from WINLine's line type (Stock / Service / Miscellaneous). If WINLine tracks expected receipts against POs, Acumatica's Receipts functionality provides equivalent tracking.
WINLine
Invoice / AR Invoice
Acumatica
AR Invoice (AR301000)
1:1WINLine AR invoices map to Acumatica AR Invoices. Invoice number, date, customer, line items, tax amounts, and payment terms carry over. WINLine's invoice-level discounts map to Acumatica's CuryDiscTot/CuryOrigDocAmt fields. If WINLine invoices reference shipment numbers, we map those to Acumatica's shipment reference on the AR document.
WINLine
Custom Property (on any entity)
Acumatica
Custom Field (UI-defined DAC extension)
1:1WINLine custom properties on any entity (customer, vendor, item, order) have no direct Acumatica equivalent — they require a custom field definition in Acumatica's Customization Project Editor before data can be populated. We inventory every WINLine custom property during discovery, define the corresponding Acumatica custom field, then load values during the entity import phase.
WINLine
User / Owner
Acumatica
User (PX.Actors.User)
1:1WINLine users and record owners are resolved by email match against Acumatica Users. If a WINLine owner has no corresponding Acumatica user, we flag the record and assign it to a fallback owner specified in the migration plan. WINLine security roles do not migrate — Acumatica roles and screens must be assigned by the destination admin post-migration.
WINLine
Payment Terms
Acumatica
Cash Discount / Payment Rule (AP/AR Setup)
1:1WINLine payment terms (Net 30, 2/10 Net 30, etc.) map to Acumatica Payment Terms with value mapping. Due Type (离 due days, discount days) maps to Acumatica's Cash Discount settings. Custom WINLine payment terms are preserved as custom Payment Terms in Acumatica during configuration.

Pair-specific challenges
Migration approach
Inventory WINLine data and configure Acumatica schema
We begin every WINLine migration with a full data inventory — counting customers, vendors, inventory items, open orders, GL accounts, and custom properties by type and count. For each WINLine entity we identify the full set of fields and any custom properties attached to that entity. In parallel, we configure Acumatica: set up the Organization and Branch structure, define the Chart of Accounts (creating Subaccounts for any multi-segment WINLine GL codes), create ItemClass records, define Payment Terms, and pre-create every custom field that WINLine custom properties require. This schema-first approach ensures Acumatica is ready to receive data when the import phase begins.
Extract, cleanse, and transform WINLine data for Acumatica's relational model
WINLine exports customer and vendor records as flat rows — we transform these into Acumatica's BAccount + Contact + Location model by parsing address and contact sub-fields and assigning them to the correct entity. Inventory items are classified against the pre-created ItemClass records. Open sales and purchase orders are extracted with their full line detail including GL account assignments. We assign Acumatica Branch IDs to each record based on the WINLine company or warehouse code, and we map WINLine owner IDs to Acumatica users by email match. AUDIT logging captures every transformation decision for reconciliation.
Run a sample migration with field-level diff and validation
Before the full migration commits, we run a representative slice — typically 200–500 records per entity type including customers, vendors, items, and orders. We generate a field-level diff comparing WINLine source values to the Acumatica destination values for each mapped field. This reveals missing custom field definitions, incorrect value mappings, entity split issues (BAccount vs. Contact vs. Location), and owner resolution failures. The Acumatica admin reviews the diff and we adjust the mapping configuration until the sample passes validation before the full run is authorized.
Execute full migration with delta-pickup and cutover
The full migration runs against Acumatica using bulk API ingestion for large record sets. A delta-pickup window of 24–48 hours after the initial load captures any WINLine records modified during the cutover period — open orders entered, inventory adjusted, or customer details updated. Our migration engine replays only changed records during this window to keep the delta lean. Once delta-pickup completes, the Acumatica admin runs a final validation report and confirms go-live. Our AUDIT log provides a full record of every record inserted, updated, or skipped with reason codes.
Hand off workflow rebuild reference and post-migration support
After data migration completes, we deliver the WINLine workflow definitions as a structured reference document keyed to Acumatica's automation tools — covering approval thresholds, email triggers, conditional routing, and scheduled automations. The Acumatica admin uses this document to rebuild WINLine automations in Acumatica Process Automation, Business Events, or Generic Inquiries. We remain available for a 30-day post-migration support window to address data discrepancies found during the first reconciliation cycle and to assist with any field mapping corrections that surface in live usage.
