It is possible to download a proof of transfer directly from your Qonto interface, in case of request for a proof by a third party, for example.
Go to your Business Account section webapp (desktop only), in the "History" tab. Find the transfer for which you want a proof of transfer and click on it.
In the side panel, click on "Download proof of payment" to download the document as below.
Note: This document can be downloaded only if the transfer has been executed.
