Expense claims duplicates
A 'duplicate' warning will be visible on Spendesk:
If the Requester submits the same expense claims twice.
If the Requester submits an expense claim similar to a payment they've already made with their Spendesk physical card.
If the Requester submits a receipt that they've already uploaded.
The different checks our tool makes are on:
date+amount (if the supplier has not been filled or detected)
🔥 If the Requester submits the expense even though it's a duplicate, the Controller is warned on the request.
🔥 If the Requester submits the expense another user has already submitted, the link to the duplicate request is displayed.
As a Requester, I want to avoid submitting the same invoice several times. As a Controller, I want to make sure I don't pay the same supplier twice!
This is why we flag invoice duplicates.
When Requesters submit an invoice that has already been submitted (i.e the same file or same supplier + invoice number), then they immediately get a warning at the bottom of the request panel, and can either delete the invoice or submit it anyway.
What do we check?
The document added by the users and information it contains.
To detect duplicates, there are two checks:
An algorithm called
checksumis applied on the file. This extracts a value that represents the number of bits in the document meaning that two exact same documents will have the same
checksum, but if they differ by even one bit the checksum's different (more info on checksums here).
the 2d check is to see if there’s a match on supplier & invoice number for already submitted invoices. This is dependent on the OCR extraction (because the OCR extraction gives us the supplier & invoice number from the file).
If there’s a match in step 1 or step 2 then we show the "duplicate detected "panel on the draft request:
If a Controller reviews an invoice that has already been reviewed, they get a warning so as to reject it and to avoid paying it twice. Only receipts added as invoices previously are flagged to the Controller.
