Why teams connect Acumatica and SAP S/4HANA

Two ERPs, one set of facts: Stacksync keeps Acumatica and SAP S/4HANA consistent in real time, whether they split the business or one is replacing the other.

Subsidiaries on Acumatica reporting into a corporate SAP S/4HANA core connect the two ERPs to keep financial and order data consistent. Acumatica Sales Orders and Invoices sync with S/4HANA Sales Orders and Billing Documents, while Customers and Vendors map to S/4HANA Business Partners.

Stacksync syncs Stock Items, Shipments, Payments, Journal Transactions in Acumatica with Customer / Supplier Roles, Production Orders, Business Partners, Sales Orders in SAP S/4HANA 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.

  • 02 Align Acumatica Stock Items with S/4HANA Products / Materials for a shared catalog.
