You need to upload a photo of a purchase invoice, not a receipt or other document.
A purchase invoice (known as a "facture" in French!) is an invoice containing the following information:
Shop name and address
Buyer name and address (your invoice should be addressed Wevat - see below)
Date of purchase
An invoice number
Description of each item purchased
VAT rate of each of the items and the total purchase value
To get your tax refund, your invoices must be addressed to Wevat, not yourself. If the invoice is not addressed to Wevat, it will be rejected and we won't be able to refund you.
