Website–ERP integration: connect systems without a risky rewrite
Website–ERP integration is how orders, stock, prices, and customer accounts stay consistent between your customer-facing site (or portal) and the ERP that runs the business.
UK SMEs often search for "website integration services" after a shiny front end has drifted from operational reality. The fix is usually integration discipline — not another redesign.
When integration beats replacement
If the ERP correctly encodes decades of pricing, BOM, or warehouse rules, keep it. Integrate a modern web layer for customers and staff. Replacement projects fail when teams underestimate edge cases buried in the old system.
Integration is the right move when you need faster UX, web access, or partner connectivity, and the ERP still does the commercial maths correctly.
Common integration patterns
Direct API calls where the ERP exposes stable endpoints; a middleware or iPaaS layer when you have multiple systems; file drops only as a temporary bridge. Event-driven updates help stock and order status feel "live" without hammering the ERP with constant polls.
- Customer and ship-to synchronisation
- Price and discount resolution
- Stock / ATP reads
- Sales order create and status
- Invoice and document retrieval
Risk controls that matter
Idempotent order posts, clear ownership when sync fails, monitoring, and a manual replay path for the ops team. Never let the website invent credit approval the ERP would refuse.
Our legacy ERP modernisation case study shows the wider pattern: modern interface, preserved core logic. Portals follow the same principle on the customer side.
