### How CryptoPay Server works?

CryptoPay Server is a self-hosted and automated invoicing system. At checkout, a customer is presented with an invoice that they pay from their wallet. CryptoPay Server follows the status of the invoice through the blockchain and informs you when the payments has been settled so that you can fulfill the order. It also takes care of payment refunding and crypto management alongside plenty of other features.
