Why teams connect Acumatica and IBM AS/400

Give your engineers Acumatica's data in IBM AS/400: read it with normal queries, write back through the sync, and skip the ERP API entirely.

ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.

Stacksync mirrors Sales Orders, Invoices, Purchase Orders, Stock Items from Acumatica into IBM AS/400 and keeps both sides consistent in real time. Whatever Acumatica is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in IBM AS/400 sync back into Acumatica with its validations respected.

Common use cases

  • Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.
  • Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • Replicate journal transactions and financial data into a SQL database for reporting and consolidation.
  • Sync vendor bills from AP automation tools into Acumatica for approval and payment.

Read ERP records with a query

Records from Acumatica live in IBM AS/400 as ordinary tables or collections, joinable with the rest of your data.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Acumatica interface, limits, and retries.

React to ERP changes

Updates in Acumatica arrive as row changes in IBM AS/400, so jobs and triggers can respond as the business record changes.

What you can sync between Acumatica and IBM AS/400

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.
