Why teams connect Sage 300 and SAP
Two ERPs, one set of facts: Stacksync keeps Sage 300 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 Inventory Items, AR Invoices and Receipts, AR Customers, AP Vendors in Sage 300 with GL Accounts and Journal Entries, Production Orders, Inventory / Stock, Cost Centers 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
- Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.
- Sync AR customers, invoices, and balances into a CRM for multi-currency account visibility.
- Publish plant-level inventory to e-commerce and planning systems on change or on schedule.
- Replicate journal entries and billing documents to a warehouse for finance analytics without loading the ERP.
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 Sage 300 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.
| Sage 300 objects | SAP objects | |
|---|---|---|
| Purchase Orders Procurement documents read for spend visibility and receiving. | Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs. | |
| Inventory Items Item master with costing and quantities, synced to storefronts and WMS. | Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. | |
| AR Invoices and Receipts Billing and payment records replicated for cash and revenue reporting. | Sales Orders Order documents written from external channels and read for status and fulfillment. | |
| AR Customers Receivables customer master synced to CRMs and billing tools. | Purchase Orders Procurement documents synced with supplier portals and spend tools. | |
| AP Vendors Payables vendor master synced with procurement and payment systems. | Outbound Deliveries Shipment documents synced to WMS, carriers, and customer portals. | |
| GL Accounts Chart of accounts read for transaction mapping across integrations. | Billing Documents Invoices read for AR status and replicated for revenue reporting. |

FAQ
Sage 300 and SAP integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Sage 300 and SAP: authenticate both systems, choose the objects to sync (such as Sage 300's Purchase Orders and Inventory Items), 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 Sage 300 and SAP: Split by function; Two-tier roll-up; Migration in parallel. 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.
-
Sage 300: Sage 300 Web API (REST) on newer releases; .NET/COM SDK and direct SQL Server access on-prem. Authentication: Sage 300 user credentials (Basic auth on the Web API); database credentials for direct SQL reads. 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.
-
Sage 300: Multi-currency and multi-company operation are core to the data model, and integrations must carry currency and company context on every transaction. 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 Sage 300 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 Sage 300 and SAP records are not retained after a sync operation.
