Why teams connect QAD ERP and SAP

Two ERPs, one set of facts: Stacksync keeps QAD ERP and SAP 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 Items, Customers, Suppliers, Sales orders in QAD ERP with GL Accounts and Journal Entries, Production Orders, Inventory / Stock, Cost Centers in SAP 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 Consolidate data from multiple QAD instances, per plant or region, into one reporting database.
  • 02 Sync items, customers, and orders between QAD and a CRM so sales teams work outside ERP screens.
  • 03 Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.
  • 04 Publish plant-level inventory to e-commerce and planning systems on change or on schedule.

Common sync patterns

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.

Shared master data

Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

What you can sync between QAD ERP and SAP

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.

QAD ERP objects SAP objects How this pairing syncs
Sales orders Demand records written in from EDI or e-commerce and read out for status Sales Orders Order documents written from external channels and read for status and fulfillment. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Purchase orders Procurement documents mirrored to planning and finance systems Purchase Orders Procurement documents synced with supplier portals and spend tools. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Suppliers Vendor master data aligned with procurement and AP automation tools Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. Suppliers is specific to QAD ERP and Materials (Products) to SAP — each maps to any object or custom field on the other side.
Work orders Production records replicated for scheduling and shop-floor analytics Outbound Deliveries Shipment documents synced to WMS, carriers, and customer portals. Work orders is specific to QAD ERP and Outbound Deliveries to SAP — each maps to any object or custom field on the other side.
Inventory balances Stock levels by site and location, synced for multi-plant visibility Billing Documents Invoices read for AR status and replicated for revenue reporting. Inventory balances is specific to QAD ERP and Billing Documents to SAP — each maps to any object or custom field on the other side.
General ledger transactions Financial postings exported for consolidated reporting GL Accounts and Journal Entries Financial postings replicated to warehouses for group finance analytics. General ledger transactions is specific to QAD ERP and GL Accounts and Journal Entries to SAP — each maps to any object or custom field on the other side.

How changes propagate between QAD ERP and SAP

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.

QAD ERP SAP Interval-based propagation

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

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

SAP QAD ERP Sub-second propagation

DetectionSAP notifies Stacksync of record changes through webhook events. Business events via SAP Event Mesh on S/4HANA.

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

Rate-limit considerations

  • QAD ERP: Subject to instance capacity and the platform's API limits.
  • SAP: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.
