Why teams connect Acumatica and Epicor ERP

Two ERPs, one set of facts: Stacksync keeps Acumatica and Epicor ERP 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 Payments, Journal Transactions, Projects, Opportunities and Cases in Acumatica with Parts, Sales orders, Purchase orders, Jobs in Epicor ERP 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

  • Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.
  • Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.
  • Sync shipment confirmations out to commerce platforms and customer portals as jobs complete.
  • Sync Epicor customers and AR invoices into a CRM so sales sees order history and credit status without ERP logins.

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.
