The same document may arrive through email, upload and an integration. Without duplicate controls, one business event can create several records.

The decision to make

Define identity using the document and the business context. File names alone are weak evidence because users often rename attachments.

Practical checklist

  • Track a stable processing identifier.
  • Compare relevant business references and file fingerprints.
  • Hold uncertain matches for review instead of silently deleting them.

An illustrative example

Two invoices with the same amount may be legitimate. Duplicate detection should consider supplier and reference rather than amount alone.

Your next step

Test repeated uploads and retries so an interrupted task can resume without creating a second business transaction.
