Sign in to the correct client account, open My invoices and the invoice to pay. Use only the beneficiary, bank details, currency and amount shown on that invoice. Include its reference in your transfer. An eligible unpaid invoice offers a private proof submission button with its own file formats and limits. If that button is missing, contact support and identify the invoice. Submitting or verifying a proof does not automatically mark an invoice paid: bank receipt must be reconciled. Then wait for actual service activation or operator handling.
