What should I do about exchange rate issues when paying an invoice?

Cryptocurrency exchange rates can vary slightly across wallets and services. To ensure your payment is accepted without delays or errors, always input the exact crypto amount shown on the invoice - even if the fiat value seems off in your wallet. If the system detects an overpayment, you will see a refund form directly on the invoice page after the transaction is approved. If you underpay, the invoice will remain pending and indicate the remaining balance. Make sure to send the remaining amount before the invoice expires to complete the payment.
