Allow the ability to collect fields from customers when completing payments for one-time and recurring. Be able to send the data for that field via a URL query parameter?

The ability to hold a card on-file without charging the customer, this would allow your to auto add the customer to recurring payments and pay other invoices without the customer present

It would be useful if accounts had the option to embed payment pages like, Quick Pay, Payment links and Payment plans into their website so customers don't have to visit another site to complete their payment

In the original version of SuperPay, you had the ability to text payment links directly to customers. I loved this feature and would love to see it back.

Setup the ability to easily connect Zap's to events in SuperPay. An example use case: when a customer joins a payment plan, add them to my Mailchimp email campaign

The ability to allow you to set custom terms and conditions for one-time and recurring payment links. And it let's customers accept it before checkout.

If you have clients in different countries, it would be interesting if you could generate specific payment forms in different currencies. As Stripe supports multiple currencies, it would also be very interesting if the user could choose which currency they want to pay with from a list of options that you preselect (or directly show them a currency based on their geolocation). This should be an option that can be activated in the payment forms that you want to be multi-currency. Thanks!

SuperPay operates in multiple regions and we must be able to localize payment pages for different countries

The ability to create coupon codes allowing customers to apply them at checkout.
