Why teams connect IBM AS/400 and Sage 300

Give your engineers Sage 300'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 Journal Batches, Order Entry Orders, Purchase Orders, Inventory Items from Sage 300 into IBM AS/400 and keeps both sides consistent in real time. Whatever Sage 300 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 Sage 300 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.
  • Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.
  • Sync AR customers, invoices, and balances into a CRM for multi-currency account visibility.

React to ERP changes

Updates in Sage 300 arrive as row changes in IBM AS/400, so jobs and triggers can respond as the business record changes.

Where Sage 300 is the HR system of record: people data for internal systems

Worker and org records stay current in IBM AS/400 for provisioning, access, and reporting systems that read from the database.

Controlled write-back

Choose exactly which tables and fields may flow from IBM AS/400 back into Sage 300, keeping the ERP authoritative.

What you can sync between IBM AS/400 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.

IBM AS/400 objects Sage 300 objects
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Inventory Items Item master with costing and quantities, synced to storefronts and WMS.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. AR Invoices and Receipts Billing and payment records replicated for cash and revenue reporting.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. AR Customers Receivables customer master synced to CRMs and billing tools.
Rows / records The unit of read and write, accessed via SQL or record-level access. AP Vendors Payables vendor master synced with procurement and payment systems.
Journals and journal receivers The change log that enables log-based CDC on journaled files. GL Accounts Chart of accounts read for transaction mapping across integrations.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Journal Batches GL entries staged in batches that must be posted; a common write target for external systems.
