Why teams connect Epicor ERP and SAP
Two ERPs, one set of facts: Stacksync keeps Epicor ERP and SAP 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 Purchase orders, Jobs, Quotes, AR invoices in Epicor ERP with Billing Documents, GL Accounts and Journal Entries, Production Orders, Inventory / Stock in SAP 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
- Mirror parts, on-hand inventory, and job status into a reporting database for shop-floor dashboards.
- Keep supplier and purchase order data synced with procurement or AP automation tools.
- Keep MES and WMS systems aligned with production orders and goods movements.
- Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.
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.
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.
What you can sync between Epicor ERP and SAP
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 | SAP objects | |
|---|---|---|
| Suppliers Vendor masters kept aligned with procurement and AP automation tools. | Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs. | |
| Parts Item masters that anchor inventory, BOM, and order line syncs. | Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. | |
| Sales orders Created from won CRM opportunities; status and line changes sync back out. | Sales Orders Order documents written from external channels and read for status and fulfillment. | |
| Purchase orders Synced with procurement systems and matched against receipts. | Purchase Orders Procurement documents synced with supplier portals and spend tools. | |
| Jobs Production jobs whose status feeds shop-floor dashboards and delivery-date updates. | Outbound Deliveries Shipment documents synced to WMS, carriers, and customer portals. | |
| Quotes Estimates that pair with CRM opportunities during the sales cycle. | Billing Documents Invoices read for AR status and replicated for revenue reporting. |

How the Epicor ERP and SAP connectors work
Epicor ERP
- Integration surface
- 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
- Change detection
- Polling on change-date fields; outbound calls can be wired through BPM directives, but there is no standard webhook subscription surface
- Capabilities
- read · write
- Rate limits
- Subject to the platform's API rate limits and per-tenant throttling on Kinetic cloud deployments
SAP
- Integration surface
- OData (v2/v4) APIs on S/4HANA; BAPI/RFC and IDoc on ECC and on-prem systems; SOAP services
- Authentication
- OAuth 2.0 or basic auth via communication arrangements on cloud editions; SAP user credentials for RFC on-prem
- Change detection
- Business events via SAP Event Mesh on S/4HANA; change pointers with IDocs or timestamp polling on ECC
- Capabilities
- read · write · webhooks
- Rate limits
- Throttling is configured at the gateway and tenant level rather than as a single published rate limit

FAQ
Epicor ERP and SAP integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Epicor ERP and SAP: authenticate both systems, choose the objects to sync (such as Epicor ERP's Suppliers and Parts), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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 SAP: Shared master data; Split by function; Two-tier roll-up. Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.
-
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. SAP: OData (v2/v4) APIs on S/4HANA; BAPI/RFC and IDoc on ECC and on-prem systems; SOAP services. Authentication: OAuth 2.0 or basic auth via communication arrangements on cloud editions; SAP user credentials for RFC on-prem. 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. SAP: S/4HANA's Business Partner model unifies the legacy customer and vendor masters into one object, so integrations map both roles to a single record. Stacksync's field mapping accounts for these differences between Epicor ERP and SAP 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 SAP records are not retained after a sync operation.
