Why teams connect BigQuery and Workday

Land the financial records from Workday in BigQuery continuously, and write results back, without building or maintaining a pipeline.

Finance data belongs in the warehouse: revenue, invoices, payments, and customers joined with everything else the business measures. Getting it there usually means an extraction pipeline that breaks quietly and delivers yesterday's numbers.

Stacksync syncs Payroll Results, Suppliers, Customers and Invoices, Journal Entries from Workday into tables in BigQuery in real time, and the connection works in both directions: values computed in BigQuery can be written back to fields in Workday where you want them operational. Schema changes are handled, API limits are managed, and the sync is something you configure rather than code you maintain.

Common use cases

  • Push completed payroll results into a finance system or data warehouse each pay cycle.
  • Import journal entries from external billing or expense systems into Workday Financials.
  • Maintain a customer master table in BigQuery joined across CRM, billing, and support sources
  • Feed ML feature tables in BigQuery from operational systems on a continuous schedule

Revenue joined with everything else

Analysts combine Workday's financial records with product, marketing, or operational data already in BigQuery for reporting the finance system cannot do alone.

Write-back of computed fields

Scores or segments computed in BigQuery, like payment-risk flags or customer tiers, sync back onto records in Workday where the finance team can act on them.

Queryable history for audit and reconciliation

A continuously synced copy in BigQuery gives you a durable, queryable record of financial data for month-end and audit questions.

What you can sync between BigQuery and Workday

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 Workday objects
Projects Connection scope: the service account grants access per project. Customers and Invoices Financials receivables objects synced for billing visibility where Workday Financials is used.
Tables The syncable unit: only tables can be synced per the Stacksync docs. Journal Entries Accounting entries imported from external subledgers into Workday Financials.
Partitioned tables Synced like regular tables; partition columns map to target fields. Custom Reports (RaaS) Tenant-defined reports exposed as web service endpoints, often the practical read surface for syncs.
Clustered tables Supported; clustering is transparent to the sync. Workers The central HCM record covering employment, job, and personal data; the anchor of most syncs.
Datasets Organizational container — you pick which dataset’s tables to sync. Organizations Supervisory and company hierarchies read to drive routing and reporting in other systems.
