SAP B1 ↔ Coupa — Requisitions + Invoices + Supplier Sync
The SAP Business One ↔ Coupa connector by ERPPlugs routes Coupa-approved requisitions into SAP B1 as Purchase Orders via Service Layer + DI API, matches Coupa invoices against B1 Goods Receipts three-way, and syncs Coupa SIM profiles to B1 Business Partners. Extends Coupa's enterprise spend management to mid-market SAP B1 stacks.
Coupa requisitions become SAP B1 POs, invoices reconcile three-way against B1 Goods Receipts, and Coupa SIM syncs to B1 Business Partners.
What this connector does
Coupa's enterprise reach means mid-market SAP B1 customers occasionally need Coupa — typically when they're a supplier to a Coupa-mandated buyer network. The ERPPlugs SAP B1 ↔ Coupa connector wires Coupa's Compass API into SAP B1 Service Layer + DI API. Coupa requisitions become B1 Purchase Orders with correct warehouse + GL; invoices reconcile three-way against B1 Goods Receipts; SIM supplier profiles sync to B1 Vendor BPs.
