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.

Frequently Asked Questions
Typically when the SAP B1 customer supplies to a large enterprise mandating Coupa Supplier Portal + Compass integration. This connector handles both directions — Coupa-driven procurement into B1 and B1-driven fulfillment out to Coupa buyers.
On Coupa invoice arrival, the connector queries B1 for the matching PO + Goods Receipt. Within-tolerance invoices auto-post to AP; outside-tolerance surface on the exceptions queue.
Coupa Contracts sync as B1 blanket agreements; the connector validates each requisition against the corresponding blanket before creating the PO.
Yes — approved expense reports post to B1 AP against employee BPs. Reimbursement runs through B1's standard payment.
Each Coupa requisition can specify ship-to; the connector routes the resulting B1 PO to the correct warehouse based on ship-to + business rules.
