Integrations checklist
Magento ERP & WMS Integration Scoping Checklist
ERP and WMS integrations usually fail in scoping, not in the first API call. This checklist helps Magento teams define data ownership, sync expectations, failure controls and test requirements before delivery begins.

Fit
Who this is for
- Selecting a connector, middleware platform or custom API approach
- Committing integration budget or delivery dates
- Adding new warehouse, marketplace, ERP or fulfilment workflows
- Migrating from manual exports or unreliable scheduled syncs
- Starting a Magento rebuild that depends on operational data flows
Signals
Warning signs
- Stock differs between Magento, ERP, warehouse, and marketplace channels
- Orders reach Magento but fail to reach the ERP or WMS without clear ownership
- Duplicate messages, delayed updates or retry attempts create manual exceptions
- No one reviews reconciliation variance, exception queues or failed background jobs
Checklist
Practical checks to work through
Document business process owners for sales, fulfilment, finance, returns and customer-service exceptions
Define source-of-truth decisions for every data entity before mapping fields or choosing middleware
Map order, inventory, available-to-sell stock, price, customer, shipment, refund and returns flows
Agree sync timing, retry rules, idempotency controls and exception handling for failed or delayed messages
Confirm ERP/WMS API readiness, credentials, environment access, rate constraints and support contacts
Capture SKU, warehouse, bundle, configurable product, pricing and catalogue-model complexity before build starts
Prepare staging environments with representative test data and end-to-end cases for happy paths and exceptions
Define monitoring, reconciliation, alerting, failed-job review and support ownership after launch
Plan cutover, rollback criteria and post-go-live controls before production data starts moving
Next references
Useful follow-up links while scoping
Use these when the checklist points to unclear responsibility, marketplace sync problems, a deeper store review, or slow back-office processing.
Good result
What good looks like
- Magento, ERP, WMS and marketplace flows are mapped as one operating model with named owners
- Exceptions, failed messages and stock variance are visible before customers or warehouse teams discover them
- Staging evidence proves order, inventory, price, customer and returns flows before cutover
Watch-outs
Common risks
- Scoping only the happy path and missing amendment, cancellation, partial fulfilment or returns cases
- Starting connector configuration before source-of-truth and available-to-sell ownership are agreed
- Treating middleware as ownership instead of defining monitoring, reconciliation and support responsibility
Get help
When to ask for senior help
- You need to turn checklist answers into architecture, sequence and operating controls
- Marketplace failures are caused by upstream ERP or WMS sync problems
- The integration needs custom rules beyond a standard connector
