Why teams connect Epicor ERP and Sage 100
Two ERPs, one set of facts: Stacksync keeps Epicor ERP and Sage 100 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 Parts, Sales orders, Purchase orders, Jobs in Epicor ERP with Customers, Vendors, Inventory Items, Sales Orders in Sage 100 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
- Push won opportunities from the CRM into Epicor as sales orders and sync order status back.
- Mirror parts, on-hand inventory, and job status into a reporting database for shop-floor dashboards.
- Push e-commerce and EDI orders into the Sales Order module instead of rekeying them.
- Publish item, pricing, and on-hand inventory to online catalogs 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.
What you can sync between Epicor ERP and Sage 100
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.
| Epicor ERP objects | Sage 100 objects | |
|---|---|---|
| Shipments Fulfillment confirmations synced to customer portals and commerce systems. | Sales Orders Order headers and lines, the usual write target for web and EDI orders. | |
| Bills of materials Methods of manufacturing read for costing and planning integrations. | AR Invoices Billing documents synced outward for payment status and revenue reporting. | |
| Customers Master records synced with CRM accounts so sales and the ERP agree on ownership and credit status. | Purchase Orders Procurement documents read for spend and receiving workflows. | |
| Suppliers Vendor masters kept aligned with procurement and AP automation tools. | GL Accounts Chart of accounts read for mapping transactions in finance integrations. | |
| Parts Item masters that anchor inventory, BOM, and order line syncs. | Journal Entries Posted GL activity replicated to warehouses for FP&A. | |
| Sales orders Created from won CRM opportunities; status and line changes sync back out. | Customers AR customer master records synced to CRMs for account and credit visibility. |

FAQ
Epicor ERP and Sage 100 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Epicor ERP and Sage 100: authenticate both systems, choose the objects to sync (such as Epicor ERP's Shipments and Bills of materials), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
On the Epicor ERP side: Parts, Sales orders, Purchase orders, Jobs, plus custom fields where Epicor ERP exposes them. On the Sage 100 side: Customers, Vendors, Inventory Items, Sales Orders. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Epicor ERP and Sage 100: Two-tier roll-up; Migration in parallel; Shared master data. Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.
-
Epicor ERP: REST API (OData) over Epicor business objects, plus BAQ (Business Activity Query) endpoints. Authentication: API key combined with basic or token authentication, depending on version and deployment. Sage 100: ODBC (ProvideX driver) for reads; Business Object Interface (BOI) or Sage-provided web services for writes. Authentication: Sage 100 company and user credentials; ODBC DSN credentials for direct reads. Stacksync manages authentication, retries, and rate limits on both sides.
-
Epicor ERP: BAQs (Business Activity Queries) can be exposed as read endpoints, letting integrations query joined ERP data without composing multiple object calls. Sage 100: Sage 100 (formerly MAS 90/200) is an on-premise ERP; its data files are exposed for reads through a ProvideX ODBC driver with module-prefixed tables such as AR_Customer and SO_SalesOrderHeader. Stacksync's field mapping accounts for these differences between Epicor ERP and Sage 100 without custom code.
