Why teams connect Coupa and Dynamics 365 Business Central

Keep Coupa and Dynamics 365 Business Central agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.

A dedicated finance tool and an ERP end up side by side for practical reasons: a subsidiary runs lighter software than headquarters, billing runs in a specialist system while the enterprise system holds the wider view, or the company is mid-migration and both are live. Whatever the split, the two systems describe overlapping customers and transactions, and that overlap drifts without a live connection.

Stacksync syncs Expense Reports, Requisitions, Purchase Orders, Invoices in Coupa with Payments, Customers, Vendors, Items in Dynamics 365 Business Central in real time and in both directions. You decide which system wins on which field, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • 01 Mirror Purchase Orders and their status into an operational Postgres database for spend reporting and three-way match analytics.
  • 02 Export approved Invoices and their lines from Coupa into an accounting/ERP system to drive the AP pay cycle and GL posting.
  • 03 Sync vendor and purchase order data with procurement or AP automation tools.
  • 04 Create sales orders in Business Central automatically from e-commerce or CRM order records, and sync fulfillment status back.

Common sync patterns

One customer and vendor master

Where both systems keep records of the same organizations, corrections made in either propagate to the other.

Subsidiary to headquarters

Where Coupa serves a business unit and Dynamics 365 Business Central is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

Where Coupa handles billing: invoices land in Dynamics 365 Business Central

Invoices and payment activity from the billing side post through to the enterprise system automatically.
