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
- 01 Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.
- 02 Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.
- 03 Sync shipment confirmations out to commerce platforms and customer portals as jobs complete.
- 04 Sync Epicor customers and AR invoices into a CRM so sales sees order history and credit status without ERP logins.
Common sync patterns
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.
What you can sync between Acumatica and Epicor ERP
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Acumatica objects | Epicor ERP objects | How this pairing syncs | |
|---|---|---|---|
| Customers AR master data synced with CRMs and billing tools. | Customers Master records synced with CRM accounts so sales and the ERP agree on ownership and credit status. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Sales Orders Order documents created from e-commerce and CRM systems, read back for fulfillment status. | Sales orders Created from won CRM opportunities; status and line changes sync back out. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Purchase Orders Procurement documents exchanged with supplier-facing systems. | Purchase orders Synced with procurement systems and matched against receipts. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Shipments Fulfillment documents read to update tracking in storefronts and CRMs. | Shipments Fulfillment confirmations synced to customer portals and commerce systems. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping. | |
| Journal Transactions GL entries replicated into reporting databases. | Quotes Estimates that pair with CRM opportunities during the sales cycle. | Journal Transactions is specific to Acumatica and Quotes to Epicor ERP — each maps to any object or custom field on the other side. | |
| Projects Project cost and billing structures synced with delivery tools. | AR invoices Billing records surfaced in CRM or finance tools for collections visibility. | Projects is specific to Acumatica and AR invoices to Epicor ERP — each maps to any object or custom field on the other side. |
How changes propagate between Acumatica and Epicor ERP
