The Checkout element is the most advanced component in FunnelFox. It’s designed to reduce payment friction and maximize conversion rates by handling the complete payment flow from card collection to subscription creation.
Checkout element configuration

​
Use cases

Add Checkout to your funnel for:
  • First-time purchases - Initial subscription or one-time payment.
  • Trials - Free or paid trial activation.
  • Offers - Introductory or promotional discounts (coupons) applied to the first charge to boost conversion.
For upsells and additional purchases after the initial payment, use the Purchase action on buttons instead.

​
Create Checkout

To set up a Checkout, you need at least one configured payment provider. Learn about payment integrations.
Click + Add in the Visual editor, then select Paywall Elements > Checkout and follow the steps below.

​
1. Product selection

You can skip this step if you’re creating a funnel for a single product.
Each Checkout element handles payment for one product only. To accept payments for multiple products based on user selection:
  1. Add Options or Plan picker elements earlier in the funnel.
  2. Add one Checkout element for each product you sell.
  3. Go to the Element tab for your Checkout and set Visible to Conditional.
  4. Click + Add condition and select an answer from Plan pickers or Options leading to this Checkout.
  5. Repeat for each product you want to sell.

  • purchase_completed_success: User successfully completes a purchase.
  • purchase_completed_fail: User fails to complete a purchase (e.g., due to wrong card details or insufficient funds).
  • user_email_collected: User enters a valid email (if Email input field is available on the checkout).
