Find and remove duplicate receipts ​

Why duplicates happen ​

The most common cause: a receipt is uploaded once as a PDF scan, and later entered again manually (or OCR'd a second time from a different source). The result is two receipts for the same transaction — and your VAT return counts the input VAT twice, which is a compliance error.

Amaniq's duplicate finder scans your entire receipt database and groups potential duplicates so you can review and clean them up.


How to run the duplicate finder ​

  1. Go to Expenses → Duplicate Finder.
  2. Amaniq scans your receipts and groups them by three matching strategies:
    • Same verification code (VC) — the strongest signal. Two receipts with the same TRA verification code are almost certainly the same receipt.
    • Same supplier + same amount + same month — strong signal if the amounts match exactly.
    • Same VRN + same amount + same month — useful for suppliers where the name was recorded slightly differently.
  3. Each group is shown with both receipts side by side — dates, amounts, Z-numbers, and PDF preview buttons.

Reviewing a group ​

For each group, you have two choices:

Delete one receipt — if one is clearly the duplicate (usually the manually entered one, or the one without a PDF attachment), click Delete on that receipt. The other remains.

Mark as "Not a duplicate" — if you believe the two receipts are genuinely different transactions (e.g., you bought from the same supplier for the same amount twice in one month), click Not a duplicate. Amaniq will not show this pair again.

The "Not a duplicate" dismissal is permanent and stored per pair. You will not be asked about the same two receipts again.


When to run this ​

  • Before generating your monthly VAT return — a duplicate receipt double-counts input VAT
  • After a batch import or bulk data migration
  • Any time your input VAT figure looks higher than expected
