ERP integration connects an enterprise resource planning system with other applications so business data and process events can move consistently between them. It can link quoting, procurement, ecommerce, banking, logistics and reporting to core financial and operational records.
Which records are commonly integrated?
- Customers, suppliers and products
- Quotes, sales orders and purchase orders
- Inventory and fulfillment events
- Invoices, credit notes and payments
- Accounts, currencies and tax codes
- Approval and reconciliation statuses
How should an integration be designed?
- Define the system of record for each field.
- Map identifiers, formats and business rules.
- Choose event, batch or request-based transfer patterns.
- Validate before writing to the target system.
- Handle duplicates, retries and partial failures.
- Reconcile totals and statuses end to end.
Point-to-point vs. middleware
A point-to-point connection links two systems directly. Middleware or an integration platform centralizes mappings, routing and monitoring across multiple systems. The right choice depends on scale, change frequency and operational support.
What commonly fails?
Mismatched identifiers, stale master data, unsupported custom fields, duplicate events and unclear ownership create silent discrepancies. A successful API response does not prove that the business transaction posted correctly.
What should be monitored?
Track latency, failed records, retries, duplicates, unmapped values, control totals and reconciliation exceptions. Keep enough payload and version history to reproduce the transformation without exposing unnecessary sensitive data.
