Why teams connect NetSuite and Sage 300

Two ERPs, one set of facts: Stacksync keeps NetSuite and Sage 300 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 Sales Tax Item, Billing Schedule Customer Subsidiary Relationship, Account, Accounting Period in NetSuite with AR Customers, AP Vendors, GL Accounts, Journal Batches in Sage 300 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

  • Expose item and inventory data to internal applications through a continuously synced database table.
  • Mirror journal entries and transaction lines into a warehouse for financial reporting without CSV exports.
  • Sync AR customers, invoices, and balances into a CRM for multi-currency account visibility.
  • Write web and EDI orders into Order Entry and return order status to the source channel.

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 NetSuite and Sage 300

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.

NetSuite objects Sage 300 objects
All custom objects Synced with incremental and full sync per the Stacksync docs. Inventory Items Item master with costing and quantities, synced to storefronts and WMS.
