Why teams connect PostgreSQL and Sage 300

Give your engineers Sage 300'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 Order Entry Orders, Purchase Orders, Inventory Items, AR Invoices and Receipts from Sage 300 into PostgreSQL and keeps both sides consistent in real time. Whatever Sage 300 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 Sage 300 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
  • Write web and EDI orders into Order Entry and return order status to the source channel.
  • Replicate GL, AR, and AP detail to a warehouse for consolidated multi-company reporting.

Where Sage 300 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 Sage 300, keeping the ERP authoritative.

Read ERP records with a query

Records from Sage 300 live in PostgreSQL as ordinary tables or collections, joinable with the rest of your data.

What you can sync between PostgreSQL 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.

PostgreSQL objects Sage 300 objects
Columns Field-level mapping targets; types are mapped to the connected system's field types. GL Accounts Chart of accounts read for transaction mapping across integrations.
Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution. Journal Batches GL entries staged in batches that must be posted; a common write target for external systems.
JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata. Order Entry Orders Sales orders written from e-commerce or EDI feeds.
Sequences Generate surrogate keys for rows created by inbound syncs. Purchase Orders Procurement documents read for spend visibility and receiving.
Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. Inventory Items Item master with costing and quantities, synced to storefronts and WMS.
Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. AR Invoices and Receipts Billing and payment records replicated for cash and revenue reporting.
