Why teams connect NetSuite and SAP Business One

Two ERPs, one set of facts: Stacksync keeps NetSuite 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 Subsidiary, All custom objects, Nexus, Tax Type in NetSuite with A/R Invoices, Purchase Orders, Deliveries, Journal Entries 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

  • Mirror journal entries and transaction lines into a warehouse for financial reporting without CSV exports.
  • Sync customers, sales orders, and invoices to an operational Postgres database so teams query ERP data without writing SuiteScript.
  • Mirror items, stock levels, and price lists to external channels so quotes and listings use current ERP data.
  • Replicate invoices and journal entries into a SQL database for reporting without direct ERP database access.

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.
