Why teams connect Bill and SAP Business ByDesign

Keep Bill and SAP Business ByDesign 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 Payments, Chart of Accounts, Bank Accounts, Vendor Credits and Credit Memos in Bill with Purchase Orders, Opportunities, Projects, Employees in SAP Business ByDesign 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 Write Vendors created during ERP onboarding into BILL so new payees are ready to pay without manual re-entry.
  • 02 Read Payments and payment status into a reconciliation database once bills are marked paid in BILL.
  • 03 Sync project and time data with external professional-services tools for billing.
  • 04 Sync ByDesign accounts and contacts with an external CRM so sales works outside the ERP while finance keeps the master record.

Common sync patterns

Where Bill handles billing: invoices land in SAP Business ByDesign

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.

One customer and vendor master

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