## SMB Supply Chain: Multi-tier supply chain, finally visible. ERP + WMS + CRM unified.

Export-oriented manufacturers run on five disconnected systems. We designed integration patterns across ERP, WMS, and CRM, then built the asset-tracking layer that solves the multi-tier delivery + parts-verification problem at the factory floor.

01 · THE PROBLEM

## Where they were stuck.

Our client's enterprise stack had ERP, WMS, and CRM all running in parallel, none of them talking to each other in a way that supported multi-tier supplier verification. Tracing a part back to a Tier-2 supplier for compliance took days of phone calls. The asset-tracking story was 'log into three systems and reconcile manually.'

02 · OUR APPROACH

## How we built it.

-   01 Integration patterns: API-led canonical data model in the middle (REST/GraphQL), ERP/WMS/CRM as edge systems wrapping their own data shapes
-   02 Multi-tier delivery graph in Postgres: parts traced from Tier-2 supplier → Tier-1 → assembly → finished good with timestamped chain-of-custody
-   03 Real-time WMS integration via the warehouse's existing barcode scanners, with no new hardware required
-   04 ERP/CRM ETL nightly + change-data-capture on critical fields (orders, shipments, returns) for sub-hour latency where it matters
-   05 Compliance reports generated against the multi-tier graph for audit trails on demand

> “We told them to make the systems talk to each other. They asked us why the systems existed in the first place. That's the engineering conversation we needed to have.”
