Why teams connect Acumatica and PostgreSQL

Give your engineers Acumatica'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 Journal Transactions, Projects, Opportunities and Cases, Customers from Acumatica into PostgreSQL and keeps both sides consistent in real time. Whatever Acumatica 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 Acumatica with its validations respected.

Common use cases

  • Feed reporting and BI from a continuously synced Postgres replica instead of scheduled ETL scripts
  • Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join
  • 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.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Acumatica interface, limits, and retries.

React to ERP changes

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

Where Acumatica 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.

What you can sync between Acumatica and PostgreSQL

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.

Acumatica objects PostgreSQL objects
Opportunities and Cases Built-in CRM records synced with external sales and support tools. Views Read-side projections used to expose joined or filtered data to a sync.
Customers AR master data synced with CRMs and billing tools. Materialized Views Precomputed result sets synced outward on a refresh schedule.
Vendors Supplier records aligned with procurement and AP automation. Schemas Namespaces that scope which tables a sync reads and writes.
Sales Orders Order documents created from e-commerce and CRM systems, read back for fulfillment status. Columns Field-level mapping targets; types are mapped to the connected system's field types.
Invoices AR and AP billing documents synced for payment tracking and CRM visibility. Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution.
Purchase Orders Procurement documents exchanged with supplier-facing systems. JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata.
