Step by step
- Open the invoice and choose a coin. For USDT, also choose the network (TRON or Ethereum).
- The invoice shows a fresh address, the exact amount and a QR code. The rate is locked for 30 minutes.
- Send the exact amount in one transaction. From an exchange, add its withdrawal fee so the received amount matches.
- The invoice turns paid after the network’s confirmations — see the table.
If something goes wrong
- Too little sent: the invoice shows the remainder; send it to the same address.
- Too much sent: the excess goes to your prepaid balance.
- Rate lock expired: reopen the invoice for a new rate. A payment already sent is credited at the rate when it confirms.
- Wrong network or missing memo/tag: contact support with the transaction ID.
Receipts
Every paid invoice is available as a PDF with the USD amount, the coin amount, the exchange rate and the transaction ID — without personal details unless you add them to your billing profile.
