Why teams connect Epicor ERP and Sage 300
Two ERPs, one set of facts: Stacksync keeps Epicor ERP and Sage 300 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 AP Vendors, GL Accounts, Journal Batches, Order Entry Orders in Sage 300 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.
- Replicate GL, AR, and AP detail to a warehouse for consolidated multi-company reporting.
- Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.
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.
Shared master data
Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

FAQ
Epicor ERP and Sage 300 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Epicor ERP and Sage 300: authenticate both systems, choose the objects to sync (such as Epicor ERP's Quotes and AR invoices), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Epicor ERP: The REST surface wraps Epicor business objects, so API writes pass through the same validation and business logic as the client UI. Sage 300: Sage 300 (formerly Accpac) stores each company's data in its own SQL Server database with module-prefixed tables, so direct SQL reads are a common integration path on-prem. Stacksync's field mapping accounts for these differences between Epicor ERP and Sage 300 without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Epicor ERP and Sage 300 records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Epicor ERP and Sage 300 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Epicor ERP–Sage 300 integration in-house.
