Why teams connect Acumatica and SAP

Two ERPs, one set of facts: Stacksync keeps Acumatica and SAP consistent in real time, whether they split the business or one is replacing the other.

Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.

Stacksync syncs Projects, Opportunities and Cases, Customers, Vendors in Acumatica with Materials (Products), Sales Orders, Purchase Orders, Outbound Deliveries in SAP bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.

Common use cases

  • Replicate journal transactions and financial data into a SQL database for reporting and consolidation.
  • Sync vendor bills from AP automation tools into Acumatica for approval and payment.
  • Keep MES and WMS systems aligned with production orders and goods movements.
  • Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.

Migration in parallel

When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.

Shared master data

Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

Split by function

Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.
