Why teams connect Sage 100 and SAP S/4HANA
Two ERPs, one set of facts: Stacksync keeps Sage 100 and SAP S/4HANA 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, Vendors, Inventory Items, Sales Orders in Sage 100 with Products / Materials, Billing Documents (Invoices), Deliveries, Journal Entries in SAP S/4HANA 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 Sync customers, invoices, and payment status into a CRM so sales sees AR standing without opening the ERP.
- 02 Push e-commerce and EDI orders into the Sales Order module instead of rekeying them.
- 03 Replicate material master and pricing data to e-commerce and quoting tools.
- 04 Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.
Common sync patterns
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 Sage 100 and SAP S/4HANA
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 100 objects | SAP S/4HANA objects | How this pairing syncs | |
|---|---|---|---|
| Sales Orders Order headers and lines, the usual write target for web and EDI orders. | Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Purchase Orders Procurement documents read for spend and receiving workflows. | Purchase Orders Procurement documents shared with supplier portals and spend-management tools. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Journal Entries Posted GL activity replicated to warehouses for FP&A. | Journal Entries Financial postings read into warehouses and consolidation tools for reporting. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| GL Accounts Chart of accounts read for mapping transactions in finance integrations. | Deliveries Outbound delivery status synced to customer-facing systems for order tracking. | GL Accounts is specific to Sage 100 and Deliveries to SAP S/4HANA — each maps to any object or custom field on the other side. | |
| Customers AR customer master records synced to CRMs for account and credit visibility. | Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. | Customers is specific to Sage 100 and Customer / Supplier Roles to SAP S/4HANA — each maps to any object or custom field on the other side. | |
| Vendors AP vendor master records synced with procurement and payment tools. | Production Orders Manufacturing order status surfaced in planning and operations tools. | Vendors is specific to Sage 100 and Production Orders to SAP S/4HANA — each maps to any object or custom field on the other side. |
How changes propagate between Sage 100 and SAP S/4HANA
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Sage 100 SAP S/4HANA Interval-based propagation
DetectionStacksync polls Sage 100 for changes on an incremental schedule, reading only records changed since the previous pass. Scheduled polling.
DeliveryEach detected change is written to SAP S/4HANA through its API, with automatic retries and rate-limit backoff.
SAP S/4HANA Sage 100 Interval-based propagation
DetectionStacksync polls SAP S/4HANA for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change timestamps exposed by the OData services.
DeliveryEach detected change is applied to Sage 100 as a row-level write, with types converted between the two schemas.
Rate-limit considerations
- SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.

FAQ
Sage 100 and SAP S/4HANA integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Sage 100 and SAP S/4HANA: authenticate both systems, choose the objects to sync (such as Sage 100's Sales Orders and Purchase Orders), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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. SAP S/4HANA: OData REST APIs (v2/v4), with SOAP, BAPI/RFC, and IDoc interfaces on on-premise editions. Authentication: OAuth 2.0 with communication arrangements on cloud editions; basic auth or certificate-based on-premise. Stacksync manages authentication, retries, and rate limits on both sides.
-
Sage 100: Writes should go through the Business Object Interface rather than direct file access, so module validation and GL postings are enforced. SAP S/4HANA: On-premise deployments still commonly integrate through BAPIs, RFCs, and IDocs alongside the OData surface. Stacksync's field mapping accounts for these differences between Sage 100 and SAP S/4HANA 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 100 and SAP S/4HANA records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Sage 100 and SAP S/4HANA connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Sage 100–SAP S/4HANA integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Sage 100 and SAP S/4HANA. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
