Why teams connect BigQuery and Epicor ERP

Put Epicor ERP's records in BigQuery as live tables for reporting and analysis, without extract jobs, and write results back where Epicor ERP can use them.

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 Epicor ERP carries financials, operations, workforce data, or all three, the analysis belongs in BigQuery next to everything else the company measures.

Stacksync syncs Quotes, AR invoices, Shipments, Bills of materials from Epicor ERP into tables in BigQuery continuously, managing API limits and schema drift along the way. The connection is bi-directional, so values computed in BigQuery can be written back to fields in Epicor ERP where that is useful.

Common use cases

  • Land CRM and ERP records in BigQuery continuously so dashboards reflect business systems without nightly batch jobs
  • Activate modeled BigQuery tables by syncing computed attributes back into sales and marketing tools
  • Mirror parts, on-hand inventory, and job status into a reporting database for shop-floor dashboards.
  • Keep supplier and purchase order data synced with procurement or AP automation tools.

Group reporting across systems

Combine Epicor ERP's records with data synced from other systems in BigQuery for consolidated views no single system can produce.

Write-back where Epicor ERP exposes writable fields

Classifications or reference values computed in BigQuery sync back onto the corresponding records in Epicor ERP.

Where Epicor ERP holds the books: finance reporting from live data

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

What you can sync between BigQuery and Epicor ERP

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.

BigQuery objects Epicor ERP objects
Partitioned tables Synced like regular tables; partition columns map to target fields. Customers Master records synced with CRM accounts so sales and the ERP agree on ownership and credit status.
Clustered tables Supported; clustering is transparent to the sync. Suppliers Vendor masters kept aligned with procurement and AP automation tools.
Datasets Organizational container — you pick which dataset’s tables to sync. Parts Item masters that anchor inventory, BOM, and order line syncs.
Projects Connection scope: the service account grants access per project. Sales orders Created from won CRM opportunities; status and line changes sync back out.
Tables The syncable unit: only tables can be synced per the Stacksync docs. Purchase orders Synced with procurement systems and matched against receipts.
