Why Your Invoice Is Overpaid
Bitcoin exchange rates often differ among wallets and services. This means that bitcoin amounts denominated in fiat in your wallet or account service could be more than the actual amount needed to pay the BitPay invoice.
If you choose to manually enter the invoice amount in your wallet before sending, always enter the exact bitcoin amount listed.
We recommend using a payment protocol enabled wallet to ensure that you pay the correct amount of bitcoin for any purchase. If you do not have a bitcoin wallet, you can create one using our secure, open source BitPay wallet. The BitPay wallet supports payment protocol on all mobile and desktop downloadable versions.
How To Resolve An Overpaid Invoice Issue
If you overpay, reach out to the merchant's support email address to ask for a refund of the overpaid amount. Be sure to provide the merchant with a valid bitcoin refund address.
Merchants often have different refund policies for handling overpayments. Please note that the merchant may choose to refund the original BTC amount paid or to refund the BTC equivalent of the local currency price listed on the invoice you paid. Once a refund is submitted to BitPay, it usually takes 24-48 hours to process.
