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.
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 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.
Common use cases
- Align Acumatica's built-in CRM opportunities and cases with an external sales or support platform.
- Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.
- 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.
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.
Two-tier roll-up
Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.
