Why teams connect Epicor ERP and Dynamics 365 Business Central

Two ERPs, one set of facts: Stacksync keeps Epicor ERP and Dynamics 365 Business Central 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 Sales orders, Purchase orders, Jobs, Quotes in Epicor ERP with Vendors, Items, Sales Orders, Sales Invoices in Dynamics 365 Business Central 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 Push won opportunities from the CRM into Epicor as sales orders and sync order status back.
  • 02 Mirror parts, on-hand inventory, and job status into a reporting database for shop-floor dashboards.
  • 03 Sync vendor and purchase order data with procurement or AP automation tools.
  • 04 Create sales orders in Business Central automatically from e-commerce or CRM order records, and sync fulfillment status back.

Common sync patterns

Migration in parallel

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

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.
