ERP–CRM Integration Hub for a Manufacturer

Orders, inventory, and accounts stopped living in two truths — a governed sync hub with retries, dead-letter queues, and ops visibility.

Failed syncs become tickets

The challenge

Sales promised dates CRM did not know inventory could miss. Nightly CSV jobs failed silently; nobody owned the mapping.

Our approach

We built an integration hub: idempotent syncs, mapping versioning, retries, dead-letter review, and a status board for ops.

ERP remained system of record for inventory; CRM for pipeline.

What shipped

Concrete scope included in this engagement.

  1. 1 Order and inventory sync maps
  2. 2 Idempotent message handling
  3. 3 Retry and dead-letter flows
  4. 4 Ops status board
  5. 5 Runbooks for mapping changes

The result

Promise-vs-stock mismatches fell about 60%. Failed syncs became visible tickets instead of silent drift.
