Why teams connect ClickHouse and E2 Shop System

Put E2 Shop System's records in ClickHouse as live tables for reporting and analysis, without extract jobs, and write results back where E2 Shop System can use them.

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

ERP data is some of the most asked-for data in the warehouse and some of the hardest to get: the record types are many, the APIs are strict, and extract jobs are brittle. Whether E2 Shop System carries financials, operations, workforce data, or all three, the analysis belongs in ClickHouse next to everything else the company measures.

Common use cases

  • Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • Keep purchase order data visible to planning or supplier-facing tools without direct ERP access.
  • Replicate job and work order status into a reporting database to power shop-floor and delivery dashboards.

Write-back where E2 Shop System exposes writable fields

Classifications or reference values computed in ClickHouse sync back onto the corresponding records in E2 Shop System.

Where E2 Shop System holds the books: finance reporting from live data

Financial records land in ClickHouse as they change, so period-end reporting queries current numbers rather than last night's extract.

Where E2 Shop System is the HR system of record: workforce analytics

Worker and organization data syncs into ClickHouse for headcount, cost, and planning analysis alongside other company data.
