Why teams connect Coupa and DEAR Inventory

Keep Coupa and DEAR Inventory 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 Purchase Orders, Invoices, Suppliers, Users in Coupa with Stock levels, Sale orders, Purchase orders, Customers in DEAR Inventory 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 Export approved Invoices and their lines from Coupa into an accounting/ERP system to drive the AP pay cycle and GL posting.
  • 02 Push chart-of-accounts segments and cost centers from the ERP into Coupa Accounts so Requisitions and Invoices code to the right GL.
  • 03 Sync stock levels and product data to e-commerce storefronts and a CRM so sales quotes reflect real availability.
  • 04 Push sale orders from a storefront or CRM into DEAR for fulfillment without manual re-entry.

Common sync patterns

Subsidiary to headquarters

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

Where Coupa handles billing: invoices land in DEAR Inventory

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

Migration without a hard cutover

When one system is replacing the other, run both in parallel with records matching until the switch is complete.
