Why teams connect Acumatica and Sage 300
Two ERPs, one set of facts: Stacksync keeps Acumatica 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 Invoices, Purchase Orders, Stock Items, Shipments in Acumatica with AR Invoices and Receipts, AR Customers, AP Vendors, GL Accounts 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
- Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.
- Mirror stock items and quantities to external channels so availability stays accurate across systems.
- Replicate GL, AR, and AP detail to a warehouse for consolidated multi-company reporting.
- Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.
Split by function
Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.
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.

FAQ
Acumatica and Sage 300 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Acumatica and Sage 300: authenticate both systems, choose the objects to sync (such as Acumatica's Vendors and Sales Orders), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Acumatica and Sage 300 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Acumatica–Sage 300 integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Acumatica and Sage 300. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Acumatica: Push notifications configurable on data changes, plus polling on LastModifiedDateTime fields. On Sage 300: Scheduled polling; batch-oriented modules with no webhook surface. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Acumatica side: Invoices, Purchase Orders, Stock Items, Shipments, plus custom fields where Acumatica exposes them. On the Sage 300 side: AR Invoices and Receipts, AR Customers, AP Vendors, GL Accounts. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
