Very cool. Sometimes I receive invoices in the mail that give me the option to pay online. However most of the sites require a sign up and account. The smarter sites have a widget that allows you to type in your unique invoice id and pay without signing up. This has always seemed like a possible opportunity for a SaaS product in my opinion. Essentially you'd let the site generate the invoices using your code. Give them a snippet to put on their site and handle the payment processing. Maybe give them a dashboard to see all their data.
