Check whether a receipt is a duplicate submission

Compare the evidence before creating a second expense

Compare the actual purchase evidence before merging the submissions so a duplicate upload does not become duplicate work.

If your evidence is a supplier invoice PDF, ParseMill can turn its invoice details and line items into a reviewable Excel workbook. Compare the source and correct the result before export. Receipt photos, missing-document requests and transaction matching belong in your existing receipt and accounting tools.

Two deliveries can be the same evidence without being identical files. A photograph and a PDF export may show the same receipt. Equally, two purchases from the same merchant can have identical amounts. The comparison needs source identity and context, not only a duplicate-looking filename or total.

Keep arrival identity separate from purchase identity

Assign an artifact reference to each supplied copy and a shared evidence-family reference when the relationship is confirmed. Record the arrival channel, time and relevant message. Keep the accounting decision with the authorized reviewer; identifying duplicate evidence does not by itself authorize deleting an existing financial record.

Intuit: Email receipt images describes forwarding receipt images for review. Microsoft: Save an Outlook message describes saving received messages. These mechanics explain how the same purchase evidence can reach a team more than once. The proposed duplicate card preserves the channel history while preventing repeated arrivals from being mistaken for new purchases.

Use a comparison card with a rejection branch

The following fictional cases illustrate why the review must consider more than amount. A duplicate decision should state what was checked and what remains uncertain.

For the first pair, retain both arrival records but keep one evidence-review task. For the other pairs, do not consolidate until the relationship is resolved. A changed total can indicate a correction, incomplete image or another issue that deserves a separate question.

Reconcile the work already created

Check whether either arrival generated a new query, draft expense or follow-up message. Identify the surviving work reference and ask the authorized owner to handle any financial-record correction through the proper process. Retain a link from the redundant task so staff can understand where the work went.

• Compare receipt identity and content, not only amount.
• Preserve email or upload provenance.
• Distinguish duplicate evidence from corrected evidence.
• Keep one owner for the surviving review task.
• Stop redundant reminders after the relationship is confirmed.

Do not delete a source merely to make a duplicate count disappear. If the organization's retention process calls for removing redundant copies, preserve the relevant provenance and decision in the surviving record. A cleaner image may be selected for review without losing the history of how it arrived.

Check whether consolidation remains traceable

From either arrival, a colleague should find the same surviving evidence review and its decision. From the transaction query, they should see which source is selected and why. If the trail stops at a deleted task, improve the cross-reference before scaling the process.

Use the related workflow guide for the broader receipt workflow and the workflow audit checklist to investigate repeated work from multiple channels. Test with both a true duplicate and two genuine same-amount purchases so the workflow cannot pass by relying on amount alone.
