Why teams connect Plex ERP and Sage 300

Two ERPs, one set of facts: Stacksync keeps Plex ERP 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 Production jobs, Sales orders, Purchase orders, Customers in Plex ERP with Journal Batches, Order Entry Orders, Purchase Orders, Inventory Items 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

  • 01 Keep customers, parts, and pricing aligned between Plex and the CRM the sales team uses.
  • 02 Push sales orders captured in e-commerce or EDI systems into Plex for scheduling and fulfillment.
  • 03 Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.
  • 04 Sync AR customers, invoices, and balances into a CRM for multi-currency account visibility.

Common sync patterns

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.

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.

What you can sync between Plex ERP 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.

Plex ERP objects Sage 300 objects How this pairing syncs
Purchase orders Procurement records mirrored to accounting and planning systems Purchase Orders Procurement documents read for spend visibility and receiving. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Customers Account records kept consistent with the sales team's CRM AP Vendors Payables vendor master synced with procurement and payment systems. Customers is specific to Plex ERP and AP Vendors to Sage 300 — each maps to any object or custom field on the other side.
Suppliers Vendor records aligned with procurement and AP tools GL Accounts Chart of accounts read for transaction mapping across integrations. Suppliers is specific to Plex ERP and GL Accounts to Sage 300 — each maps to any object or custom field on the other side.
Shipments Outbound logistics records synced to trading partners and tracking systems Journal Batches GL entries staged in batches that must be posted; a common write target for external systems. Shipments is specific to Plex ERP and Journal Batches to Sage 300 — each maps to any object or custom field on the other side.
Quality records Checksheet and inspection data pulled into plant dashboards Order Entry Orders Sales orders written from e-commerce or EDI feeds. Quality records is specific to Plex ERP and Order Entry Orders to Sage 300 — each maps to any object or custom field on the other side.
Parts Item master records shared with CRM, e-commerce, and planning tools Inventory Items Item master with costing and quantities, synced to storefronts and WMS. Parts is specific to Plex ERP and Inventory Items to Sage 300 — each maps to any object or custom field on the other side.

How changes propagate between Plex ERP and Sage 300

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Plex ERP Sage 300 Interval-based propagation

DetectionStacksync polls Plex ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

DeliveryEach detected change is applied to Sage 300 as a row-level write, with types converted between the two schemas.

Sage 300 Plex ERP Interval-based propagation

DetectionStacksync polls Sage 300 for changes on an incremental schedule, reading only records changed since the previous pass. Scheduled polling.

DeliveryEach detected change is written to Plex ERP through its API, with automatic retries and rate-limit backoff.
