Common questions for building payment forms for your website

How do I set-up payments with ConvertCalculator?

We facilitate payments through Stripe. Stripe is a complete payments platform, engineered for growth. From e-commerce stores, to subscription businesses, to platforms and marketplaces, Stripe offers a complete stack for all your payment needs across channels. With 135+ currencies and dozens of payment methods Stripe makes it easy to launch new markets and add your customers’ preferred way of paying to increase conversion abroad.

Connecting your Stripe account is easy. Go to your account settings, click connect Stripe and authenticate our app. You can include payments in your form by inserting a button. Go to the button settings and toggle on "Use as form submission" and "Checkout (Payments)".

Can I also collect payments with Paypal?

Currently, we do not facilitate payments through Paypal. Don't be shy and reach out. We love to learn why offering Stripe alone is insufficient.

How do I set up subscriptions?

To set up subscriptions, you need to toggle on one more setting in your button settings: "Subscriptions". You can then set the subscription interval from daily, weekly, monthly or yearly.

Can I add a discount on a yearly subscription?

Yes you can! Remember that our product is build around formulas. In this case you would add a switch-element or a multiple choice requesting the subscription period to be monthly or yearly. You then add two buttons. One with the monthly subscription setting and one for a yearly subscription setting. By adding show/hide-logic on the buttons you only show the button associated with the plan chosen. And by using conditional logic in your formula, you can then add a discount for the yearly plan.

How do I set up a shopping cart?

Sometimes you need to sell other products, offer other payment methods, or want a richer buying experience. If this is the case we recommend to use Snipcart. It's one of the best eCommerce solutions out there, and by far the most flexible. Please follow our documentation on how to setup our Snipcart integration.
