Why teams connect Acumatica and NetSuite

Two ERPs, one set of facts: Stacksync keeps Acumatica and NetSuite consistent in real time, whether they split the business or one is replacing the other.

Organizations run Acumatica and NetSuite together across entities or during a migration and need the two ERPs to agree on financial master data. Syncing Acumatica Customers and Invoices against NetSuite Accounts, custom objects, and tax configuration keeps consolidated reporting consistent.

Stacksync syncs Opportunities and Cases, Customers, Vendors, Sales Orders in Acumatica with Nexus, Tax Type, Sales Tax Item, Billing Schedule Customer Subsidiary Relationship in NetSuite 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 Multi-entity groups map Acumatica Customers to NetSuite Customer Subsidiary Relationships for correct intercompany billing.
  • 02 Migration teams reconcile Invoices and Purchase Orders between the two ERPs during parallel run.
  • 03 Finance maintains Billing Schedules in NetSuite that reflect Sales Orders originated in Acumatica.
  • 04 Align Acumatica's built-in CRM opportunities and cases with an external sales or support platform.
