# Invoices

Invoices help merchants use RocketFuel's solution outside their website, and shoppers can visit an invoice link to make the payment using crypto exchange/wallet or bank transfers.

We are working on an invoice payment tracking feature, after which merchants will be able to track the payment status of an invoice.

Merchants who don't want to use iFrame for payment solutions can use our hosted checkout solution.
