Why teams connect Epicor ERP and SAP S/4HANA

Two ERPs, one set of facts: Stacksync keeps Epicor ERP 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 Customers, Suppliers, Parts, Sales orders in Epicor ERP with Production Orders, Business Partners, Sales Orders, Purchase 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

  • Sync Epicor customers and AR invoices into a CRM so sales sees order history and credit status without ERP logins.
  • Push won opportunities from the CRM into Epicor as sales orders and sync order status back.
  • Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.
  • Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.

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.

Migration in parallel

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