When you create a BitPay invoice it is only valid for 15 minutes. If the invoice expires, you will have to return to the merchant's website in order to submit your payment.
After the invoice window has expired, you will see the return button at the bottom of the page. Click return to be redirected to the merchant's website to generate a new invoice.
Alternatively, you can go to the merchant's website and complete your transaction by creating a new order and selecting Pay with BitPay again to generate a new invoice.
If you have trouble paying an invoice, please see our article on how to pay a BitPay invoice.
If you tried to pay for the invoice and the transaction was not accepted by the Bitcoin network, the funds will be spendable again in your wallet. Depending on your wallet, this may take 48-72 hours.
What if I sent payment to an expired invoice?
