You can pay with a credit or debit card, in which case we will charge your card automatically - five days after we issue your invoice. Additionally you can pay with Lightning or bitcoin - your invoice will include a link which will generate the amount due in sats and provide you with the Lightning or bitcoin address to use. Alternatively the invoice you receive will also include a link which will generate the bitcoin payment amount. If paying by Lightning or bitcoin, the generated spot price will remain valid for 24 hours before you will be required to generate a new invoice through the link.
