With PayWhirl there are 4 different types of Payment forms you can create. These can be:
Flexible Payment - Customers will be able to insert any amount to pay you.
Fixed Payment - Charge a customer one-time for a specified amount.
Subscription - Ties the form to the purchase of a subscription
Upsell - Ties the form to the purchase of an upsell (requires at least 1 upsell to see this option)
Once you have decided what type of form you want to create you need to give it a name. Choose to require an address or not. We recommend leaving user accounts turned on. This will help associate the payments to a subscriber.
Next if you are using a Subscription form Choose a Plan. This is the plan customers will subscribe to upon checkout.
Lastly you can configure advanced settings such as : showing the plan image, requiring profile questions, changing the purchase button text. You can even send a user to a specific thank you page after purchase by using the redirect feature.
Once you save the widget it will generate the "embed code" to copy and paste into your site.
