Unfortunately, Squirrel Street does not highlight or otherwise identify duplicate receipts.  However, by using the filtering and sorting functions in your account, we believe you can achieve the same end.

1) If you've already exported documents to accounting software or PDF/Excel reports, we suggest you filter these receipts out by going to the right hand side of the All Receipts page and removing them temporarily via the Export History filter.  Click on the down arrow shown to apply the relevant filter(s)

2) Then we suggest you sort the remaining receipts in order of total.  You do this by clicking on the word "Total" at the top of the receipt table

Sorting by total enables you to quickly see identical amounts, which often is an indication of duplicates.   If there are more than 20 documents in the filtered list, be sure to expand the page to include all applicable receipts by clicking on the largest number at the bottom of the page.

3) After you've verified that you have a duplicate, click on the entry in the list to view the document image.  Delete the document by clicking on the trashcan icon to the bottom

Continue doing this until you've deleted all the duplicates.  There should now be no more double ups when you export!
