Why teams connect PostgreSQL and QAD ERP

Give your engineers QAD ERP's data in PostgreSQL: 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 Suppliers, Sales orders, Purchase orders, Work orders from QAD ERP into PostgreSQL and keeps both sides consistent in real time. Whatever QAD ERP is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in PostgreSQL sync back into QAD ERP with its validations respected.

Common use cases

  • Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join
  • Let an application write to its own database and have those rows appear as records in business systems in near real time
  • Keep supplier and purchase-order records aligned with procurement or AP automation tools.
  • Consolidate data from multiple QAD instances, per plant or region, into one reporting database.

React to ERP changes

Updates in QAD ERP arrive as row changes in PostgreSQL, so jobs and triggers can respond as the business record changes.

Where QAD ERP is the HR system of record: people data for internal systems

Worker and org records stay current in PostgreSQL for provisioning, access, and reporting systems that read from the database.

Controlled write-back

Choose exactly which tables and fields may flow from PostgreSQL back into QAD ERP, keeping the ERP authoritative.

What you can sync between PostgreSQL and QAD ERP

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.

PostgreSQL objects QAD ERP objects
JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata. Items Item master records shared with CRM, e-commerce, and planning systems
Sequences Generate surrogate keys for rows created by inbound syncs. Customers Account records kept consistent with the sales team's CRM
Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. Suppliers Vendor master data aligned with procurement and AP automation tools
Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. Sales orders Demand records written in from EDI or e-commerce and read out for status
Views Read-side projections used to expose joined or filtered data to a sync. Purchase orders Procurement documents mirrored to planning and finance systems
Materialized Views Precomputed result sets synced outward on a refresh schedule. Work orders Production records replicated for scheduling and shop-floor analytics
