Uploading proof of payment for a SEPA transfer

Once your invoice status is Invoice ready, open your invoice and click Mark as paid, then attach your bank transfer receipt or screenshot. Accepted file types are PNG, JPEG, WebP, or PDF, up to 8 MB. After you submit, the status changes to Pending review and our team verifies it. If your proof is unclear or the amount/reference doesn't match, our team may reject the proof — you'll be notified with a reason, the status returns to Invoice ready, and you can simply upload a new, clearer proof. Note you cannot upload a second file while a proof is already under review. Your proof is stored privately and securely (the same protected storage used for KYC documents).
