In this tutorial I will show you how to accept payment online using Jotform and Stripe. If you are looking for an alternative to PayPal you might want to check out Stripe.
You can visit them at stripe.com and signing up is free. The payment processing fees are pretty much the same as the other payment processors.
Using Jotform with Stripe will make the process easier. You can use Jotform for any form you can think of. And their drag and drop feature makes things a breeze.
