Underpayments

Underpayments are incomplete payments. This means that the goods or services being purchased will not be released until the payment becomes complete.

How did this happen?

An underpayment occurs when both of the following conditions are met:

  1. The payer submits an amount less than the requested amount.

  2. The payer is paying with bitcoin on-chain.

How to resolve an underpayment

Payers can resolve (make an underpayment complete) in two ways:

1. Complete payment:

  • Click "complete payment".

  • On the next screen, a new checkout screen will appear. At the top, it will say how much BTC you have already paid. Underneath it will be a new BTC amount. The top-up payment must be completed on-chain and it must be the exact amount. In the example below, the amount that needs to be paid is exactly 0.00005 BTC.

  • That's it! When the payment confirms on-chain, the payment will now be resolved.

2. Initiate a return,

  • Click "request a refund".

  • On the next screen, enter an on-chain bitcoin address and an email address (if one is not already filled for you).

    • Note: Underpayment refunds will not be sent to a Lightning Network invoice.

    • Click “Request refund” when the form is filled out.

    • That's it! Underpayment refunds can take up to 24 hours to initiate. You'll receive an email as a receipt of your refund.
