Why teams connect SAP and SAP Business One

Two ERPs, one set of facts: Stacksync keeps SAP and SAP Business One 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 / Stock, Cost Centers, Business Partners, Materials (Products) in SAP with Sales Orders, A/R Invoices, Purchase Orders, Deliveries in SAP Business One 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

  • 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.
  • Sync activities and service data with external support tools for teams that do not log into Business One.
  • Two-way sync of business partners between SAP Business One and a CRM so sales edits and finance records converge on one customer master.

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 SAP and SAP Business One

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.

SAP objects SAP Business One objects
Purchase Orders Procurement documents synced with supplier portals and spend tools. Items Product master data including inventory levels, aligned with e-commerce and warehouse systems.
Outbound Deliveries Shipment documents synced to WMS, carriers, and customer portals. Sales Orders Order documents with header and line structure created from external channels.
Billing Documents Invoices read for AR status and replicated for revenue reporting. A/R Invoices Billing documents synced outward for CRM visibility and payment tracking.
GL Accounts and Journal Entries Financial postings replicated to warehouses for group finance analytics. Purchase Orders Procurement documents exchanged with supplier-facing tools.
Production Orders Manufacturing orders exchanged with MES and scheduling systems. Deliveries Fulfillment documents read to update shipment status in external systems.
Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. Journal Entries GL postings replicated for financial reporting.
