Why teams connect E2 Shop System and PostgreSQL

Give your engineers E2 Shop System's data in PostgreSQL: read it with normal queries, write back through the sync, and skip the ERP API entirely.

E2 Shop System is a read-only source: Stacksync reads its data in real time and delivers it into PostgreSQL, so PostgreSQL always reflects the current state of E2 Shop System — without exports, scripts, or schedulers.

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 Quotes / Estimates, Jobs / Work orders, Customers, Vendors from E2 Shop System into PostgreSQL and keeps both sides consistent in real time. Whatever E2 Shop System 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 E2 Shop System 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
  • Sync customer and invoice data to accounting or CRM so the front office is not re-keying from the ERP.
  • Land quote, job cost, and time-ticket data in a warehouse for margin analysis across jobs.

Controlled write-back

Choose exactly which tables and fields may flow from PostgreSQL back into E2 Shop System, keeping the ERP authoritative.

Read ERP records with a query

Records from E2 Shop System 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 E2 Shop System interface, limits, and retries.

What you can sync between E2 Shop System 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.

E2 Shop System objects PostgreSQL objects
Parts Part masters with routings and material definitions specific to each shop. Materialized Views Precomputed result sets synced outward on a refresh schedule.
Routings / Operations Per-part operation sequences that carry estimated and actual times. Schemas Namespaces that scope which tables a sync reads and writes.
Purchase orders Outside material and service purchases tied to jobs. Columns Field-level mapping targets; types are mapped to the connected system's field types.
Time tickets Labor collection records used for job costing. Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution.
Invoices Billing records synced to accounting for AR reporting. JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata.
Quotes / Estimates Job shop quotes with material and routing cost buildups; the start of the order lifecycle. Sequences Generate surrogate keys for rows created by inbound syncs.

How the E2 Shop System and PostgreSQL connectors work

E2 Shop System

Integration surface
No broadly documented public web API; integration typically works through the underlying database or application import/export, depending on deployment
Authentication
Database credentials or application-level export access on the on-premises installation
Change detection
Polling database tables or scheduled exports
Capabilities
read
Rate limits
Not API-bound; constrained by on-premises database access windows

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
Change detection
Logical replication (wal_level = logical) for change data capture via the "Postgres" connector; database triggers (TRIGGER grant + stacksync_logging schema) via the trigger-based "Postgres Heroku" connector where
Capabilities

Rate limits
No API rate limits; throughput is bounded by connection limits, instance resources, and replication slot throughput
