Overview
Weclapp ERP stores CRM contacts, companies, sales quotes, sales orders, purchase orders, invoices, and inventory items in a unified object graph designed for small-to-midsize teams. Acumatica separates these concerns into discrete modules — Financial Management, Distribution, Manufacturing, and CRM — each exposing data through Data Access Classes (DACs) and requiring a Usr-prefix convention for any custom fields. The migration extracts the complete transactional history from weclapp — orders, invoices, credit memos, and related documents — and loads it into the corresponding Acumatica modules while marking any weclapp-specific configurations such as email automation rules, workflow triggers, and form customizations for manual reconstruction. FlitStack respects foreign-key constraints by sequencing the load: Customers and Vendors first, then Inventory Items, then transactional documents (Sales Orders, Purchase Orders, Invoices), and finally Projects and Project Tasks. All original timestamps, owner assignments, and audit fields are preserved in Acumatica. A delta‑pickup window runs after the initial batch, capturing any in‑flight weclapp records created or modified during cutover so that the Acumatica environment reflects the final state at go‑live. The Usr-prefixed custom fields are deployed via a Customization Project generated by FlitStack and published in the Acumatica Customization Project Editor before data insertion.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a weclapp 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.
weclapp erp
Customer
Acumatica
Customer (BAccount + CR.Customer)
1:1Weclapp customers map 1:1 to Acumatica's Customer DAC. The CustomerType field determines whether the record is a Business Account or an Individual — weclapp customers without a company name route to the Individual type. Primary contact details, addresses, and tax registration numbers carry over as-is.
weclapp erp
Sales Order
Acumatica
SOOrder + SOLine (ARTran)
1:1Weclapp sales orders are monolithic records with line items embedded. Acumatica splits these into SOOrder (header: customer reference, order date, warehouse) and SOLine (line: inventory ID, quantity, unit price). The order total recalculates from SOLine aggregation in Acumatica's financials, ensuring tax and discount calculations reflect the latest line data.
weclapp erp
Purchase Order
Acumatica
POOrder + POLine
1:1Similar to sales orders, weclapp purchase orders contain header and line data in one object. Acumatica separates POOrder (vendor, terms, warehouse) from POLine (vendor stock code, ordered quantity, cost). POLine.VendorID resolves from weclapp's supplier record, ensuring accurate cost assignment and terms alignment during the migration.
weclapp erp
Invoice (Sales)
Acumatica
ARInvoice + ARTran
1:1Weclapp invoices map to Acumatica's Accounts Receivable module. The ARInvoice holds the invoice number, customer reference, and terms; ARTran holds line items linked to InventoryItem. Tax amounts from weclapp recalculate against Acumatica's tax zone configuration, ensuring correct sales tax and discount handling in the target system.
weclapp erp
Invoice (Purchase)
Acumatica
APInvoice + APLine
1:1Weclapp purchase invoices become APInvoice + APLine in Acumatica. VendorID resolves by matching weclapp supplier name or tax ID to Acumatica's Vendor DAC. Prepayments and credit memos from weclapp map to corresponding APPayment records, ensuring accurate AP reconciliation and payment application during migration.
weclapp erp
Item / Product
Acumatica
InventoryItem + INSiteStatus
1:1Weclapp inventory items map to Acumatica's InventoryItem DAC. Stock item vs. non-stock item classification carries over. Multiple warehouses in weclapp become INSiteStatus records per item — on-hand quantities split by warehouse ID, ensuring correct valuation method assignment per item for cost layer calculations.
weclapp erp
Project
Acumatica
PMProject + PMTask
1:1Weclapp projects with billable time and expense tracking migrate to PMProject. Each project task in weclapp becomes a PMTask linked to the PMProject. Billing rules (time-and-materials vs. fixed price) transfer as project attributes, preserving original project IDs and owner assignments for audit continuity.
weclapp erp
Contact (CRM)
Acumatica
Contact (CR.Contact)
1:1Weclapp CRM contacts map to Acumatica's Contact DAC. Each contact links to a Customer (BAccount) via the CR.Contact relations table. Email, phone, and job title fields transfer directly; custom contact properties become Usr-prefixed fields, maintaining contact source attribution for reporting and segmentation.
weclapp erp
Quote
Acumatica
SOShipment (Quote type) or standalone CR.Quote
1:manyWeclapp quotes require a decision: open quotes migrate as CR.Quote records if Acumatica's Quote functionality is licensed; otherwise, they convert to Sales Orders with a 'Pending' status for manual review before confirmation. The choice is recorded in the pre-migration plan to avoid orphaned quote records.
weclapp erp
Payment / Cash Entry
Acumatica
ARPayment + CashSale
1:1Weclapp payment records linked to invoices map to Acumatica's ARPayment with Application entity linking to the related ARInvoice. Cash sales without invoice references become CashSale records in the Cash Management module, ensuring accurate cash application and reconciliation in the target system.
weclapp erp
Stock Adjustment
Acumatica
INAdjustment
1:1Weclapp stock adjustments (cycle counts, damage write-offs) map to INAdjustment records. The adjustment reason code from weclapp maps to INAdjustment.reasonCode — reason codes must be pre-created in Acumatica's Inventory preferences, to ensure audit trails reflect the correct adjustment type after migration.
weclapp erp
User-Defined Custom Fields
Acumatica
Custom Fields (Usr-prefixed)
1:1Any user-defined fields in weclapp (beyond standard properties) require custom field creation in Acumatica's Customization Project Editor with a Usr prefix. FlitStack generates the customization package with field definitions and default values, including data type, pick‑list options, and visibility settings, before the data migration runs.

Pair-specific challenges
Migration approach
Audit weclapp data model and Acumatica module license scope
FlitStack connects to weclapp via API to enumerate all entity types, record counts, and user-defined fields. Simultaneously, we identify which Acumatica modules are licensed (Financial Management, Distribution, Manufacturing, CRM) because object availability depends on module scope. This determines the full object list eligible for migration and flags any weclapp entities — such as project budgets or serialized inventory — that require Acumatica's Advanced Module counterparts.
Generate Acumatica Customization Project for Usr-prefix fields
Any user-defined fields found in weclapp are catalogued and their data types mapped to Acumatica equivalents (string, integer, boolean, date). FlitStack generates the Customization Project XML with all Usr field definitions, including default values and pick‑list configurations. This package is delivered to the Acumatica admin for upload and publication to the target tenant before any data records are loaded — Acumatica enforces schema‑first field creation.
Resolve foreign-key dependencies in migration sequence
Acumatica enforces referential integrity: Customers must exist before Sales Orders, Stock Items before Purchase Orders, Projects before Project Tasks. FlitStack sequences the migration in dependency order — Customers and Vendors first, then Inventory Items, then transactional documents (Orders, Invoices), then Projects and Tasks. Unmatched foreign keys (e.g., a weclapp customer with no Acumatica counterpart) are flagged and resolved via a lookup fallback rule (Tax ID, then name match) before the batch runs.
Run sample migration with field-level diff on 100-500 records
A representative slice — typically 100-500 records covering customers, items, orders, invoices, and one project — migrates to a staging Acumatica company. FlitStack produces a field-level diff report comparing source values against destination field contents, highlighting discrepancies in totals, currency amounts, and date precision. The customer reviews the diff and approves the mapping before the full run commits. Quote disposition and warehouse-split decisions are confirmed at this stage.
Execute full migration with delta-pickup window
The full record set migrates in dependency order with transactional integrity checks at each batch. A delta-pickup window — typically 24-48 hours after the migration start — captures any weclapp records created or modified during cutover. All operations are logged in an audit table with source system ID for traceability. If reconciliation identifies mismatched totals or missing records, one-click rollback reverts the Acumatica tenant to its pre-migration state for re-run.
