Why teams connect DEAR Inventory and SAP Business One
Two ERPs, one set of facts: Stacksync keeps DEAR Inventory 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 Stock adjustments and transfers, Assemblies / Production, Locations, Products in DEAR Inventory with Purchase Orders, Deliveries, Journal Entries, Warehouses 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
- 01 Land orders, costs, and inventory movements in a warehouse for margin and stock-turn reporting.
- 02 Keep supplier and purchase order data aligned with the accounting system for accrual accuracy.
- 03 Sync activities and service data with external support tools for teams that do not log into Business One.
- 04 Two-way sync of business partners between SAP Business One and a CRM so sales edits and finance records converge on one customer master.
Common sync patterns
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.
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.
What you can sync between DEAR Inventory 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.

DEAR Inventory: DEAR Systems was acquired by Cin7 and the product now operates as Cin7 Core; the API and data model carried over from DEAR. SAP Business One: User-defined fields (prefixed U_) and user-defined objects appear on the same API surface as standard fields, so tenant customizations are reachable by syncs. Stacksync's field mapping accounts for these differences between DEAR Inventory and SAP Business One without custom code.
