Why teams connect PostgreSQL and SAP Business One

Give your engineers SAP Business One'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 Price Lists, Activities, Business Partners, Items from SAP Business One into PostgreSQL and keeps both sides consistent in real time. Whatever SAP Business One 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 SAP Business One with its validations respected.

Common use cases

  • Let an application write to its own database and have those rows appear as records in business systems in near real time
  • Consolidate data from several microservice databases into one operational Postgres store
  • Create sales orders in Business One from e-commerce platforms and sync delivery and invoice status back to the storefront.
  • Mirror items, stock levels, and price lists to external channels so quotes and listings use current ERP data.

Controlled write-back

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

Read ERP records with a query

Records from SAP Business One live in PostgreSQL as ordinary tables or collections, joinable with the rest of your data.

Internal tools and automations without API code

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

What you can sync between PostgreSQL and SAP Business One

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 SAP Business One objects
Sequences Generate surrogate keys for rows created by inbound syncs. Purchase Orders Procurement documents exchanged with supplier-facing tools.
Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. Deliveries Fulfillment documents read to update shipment status in external systems.
Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. Journal Entries GL postings replicated for financial reporting.
Views Read-side projections used to expose joined or filtered data to a sync. Warehouses Stock locations that scope inventory quantities in item syncs.
Materialized Views Precomputed result sets synced outward on a refresh schedule. Price Lists Pricing data synced to quoting and e-commerce platforms.
Schemas Namespaces that scope which tables a sync reads and writes. Activities CRM-style tasks and interactions aligned with external sales tools.

How the PostgreSQL and SAP Business One connectors work

PostgreSQL

Integration surface
SQL wire protocol (PostgreSQL frontend/backend protocol)
Authentication
Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host); a least-privilege DB user
