Why teams connect Epicor ERP and PostgreSQL

Give your engineers Epicor 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 AR invoices, Shipments, Bills of materials, Customers from Epicor ERP into PostgreSQL and keeps both sides consistent in real time. Whatever Epicor 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 Epicor ERP with its validations respected.

Common use cases

  • 01 Consolidate data from several microservice databases into one operational Postgres store
  • 02 Feed reporting and BI from a continuously synced Postgres replica instead of scheduled ETL scripts
  • 03 Sync Epicor customers and AR invoices into a CRM so sales sees order history and credit status without ERP logins.
  • 04 Push won opportunities from the CRM into Epicor as sales orders and sync order status back.

Common sync patterns

Where Epicor 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 Epicor ERP, keeping the ERP authoritative.

Read ERP records with a query

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

What you can sync between Epicor ERP 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.

Epicor ERP objects PostgreSQL objects How this pairing syncs
Quotes Estimates that pair with CRM opportunities during the sales cycle. Materialized Views Precomputed result sets synced outward on a refresh schedule. Quotes is specific to Epicor ERP and Materialized Views to PostgreSQL — each maps to any object or custom field on the other side.
AR invoices Billing records surfaced in CRM or finance tools for collections visibility. Schemas Namespaces that scope which tables a sync reads and writes. AR invoices is specific to Epicor ERP and Schemas to PostgreSQL — each maps to any object or custom field on the other side.
Shipments Fulfillment confirmations synced to customer portals and commerce systems. Columns Field-level mapping targets; types are mapped to the connected system's field types. Shipments is specific to Epicor ERP and Columns to PostgreSQL — each maps to any object or custom field on the other side.
Bills of materials Methods of manufacturing read for costing and planning integrations. Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution. Bills of materials is specific to Epicor ERP and Primary and Unique Keys to PostgreSQL — each maps to any object or custom field on the other side.
Customers Master records synced with CRM accounts so sales and the ERP agree on ownership and credit status. JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata. Customers is specific to Epicor ERP and JSONB Columns to PostgreSQL — each maps to any object or custom field on the other side.
Suppliers Vendor masters kept aligned with procurement and AP automation tools. Sequences Generate surrogate keys for rows created by inbound syncs. Suppliers is specific to Epicor ERP and Sequences to PostgreSQL — each maps to any object or custom field on the other side.

How changes propagate between Epicor ERP and PostgreSQL

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.

Epicor ERP PostgreSQL Interval-based propagation

DetectionStacksync polls Epicor ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change-date fields.

DeliveryEach detected change is applied to PostgreSQL as a row-level write, with types converted between the two schemas.

PostgreSQL Epicor ERP Sub-second propagation

DetectionChanges in PostgreSQL are captured at the source via change data capture — no polling loop against its API. Logical replication (wal_level = logical) for change data capture via the "Postgres" connector.

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

Rate-limit considerations

  • Epicor ERP: Subject to the platform's API rate limits and per-tenant throttling on Kinetic cloud deployments.
  • PostgreSQL: No API rate limits; throughput is bounded by connection limits, instance resources, and replication slot throughput.
