Why teams connect QuickBooks and SAP S/4HANA

Keep QuickBooks and SAP S/4HANA 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 Credit memos, Customers, Invoices, Payments in QuickBooks with Products / Materials, Billing Documents (Invoices), Deliveries, Journal Entries in SAP S/4HANA 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

  • Create QuickBooks invoices automatically from closed-won deals or e-commerce orders.
  • Keep customer records consistent between QuickBooks and support or subscription-management tools.
  • Replicate material master and pricing data to e-commerce and quoting tools.
  • Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.

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 QuickBooks serves a business unit and SAP S/4HANA is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

Where QuickBooks handles billing: invoices land in SAP S/4HANA

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