How to Handle Possible Duplicate Extractions in Tofu

Tofu flags possible duplicate extractions when an AP Bill, AR Invoice, or Direct Expense shares the same invoice date, total amount, and contact as another extraction. This article explains how to review the warning and decide what to do next.

When Tofu Flags a Possible Duplicate

For AP Bills, AR Invoices, and Direct Expenses, Tofu compares the following details across your extractions:

  • Invoice Date

  • Total Amount

  • Contact

When two or more extractions match on all three, a duplicate warning appears on the affected extractions in the Extractions column.

The warning only appears for extractions in Needs Review. Once an extraction is verified, the warning is hidden.

How to Review a Possible Duplicate

  1. Click the duplicate warning on the flagged extraction.

  2. Tofu shows you which extraction it duplicates, so you can compare the two side by side.

  3. If there is more than one possible duplicate, expand the list to view all of them.

How to Resolve a Possible Duplicate

Review the flagged extraction against the extraction it duplicates, then choose the option that fits:

  • It is a true duplicate. Delete the redundant extraction, or resolve the underlying source documents if the same file was also uploaded twice.

  • Both are legitimate. Some documents naturally share the same date, amount, and contact, for example a recurring monthly bill from the same supplier. If both extractions are valid, continue your review as normal. The warning clears once the extraction is verified.

💡 Tip: The duplicate warning does not block verifying or publishing. It is there to help you double check before data reaches your accounting software.

Duplicate Extractions vs Duplicated Documents

Tofu detects duplicates in two ways:

  • Duplicated documents. The same file is uploaded more than once. These are labeled Duplicated in the Source Documents panel.

  • Possible duplicate extractions. Different files produce extractions with matching invoice date, total amount, and contact.

Best Practices

  • Review the duplicate warning before verifying, since it is hidden once the extraction is verified.

  • When deleting a duplicate, keep the extraction with the better source document or the more complete data.

  • If duplicates keep appearing from the same channel, check whether the same folder or inbox is connected twice in your upload integrations.
