Setup SaaS Pricing Plans

NextAppFast allows you to visually configure SaaS Pricing plans and integrate them with Stripe.

  2. Create a new product in Stripe (Dashboard -> Products -> Add Product).
  3. Copy the Stripe Price API key for your product. (It will start with 'price_')
  4. Run your app in NextAppFast (preview mode)
  5. Locate Subscription Plan menu item under the Admin section.
  6. Add your product and enter the Stripe Price API key in the Stripe Plan Id field.
  7. When you generate code for your app, NextAppFast will create a plans.ts file based on your entries in Subscription Plan table. It is this file that is used by pricing page. You can locate the file in \app\(checkout)\checkout\_components folder.
  8. Customize the plans.ts file as needed to adjust the features for each pricing plan.


Checkout is handled via Stripe Checkout. When a user selects 'Checkout', the NextAppFast-generated code creates a Stripe Checkout Session and redirects the user to the Stripe-generated URL.You can find relevant code in app\(checkout)\checkout\_actions.tsx folder.

After the user completes the payment, the return call from Stripe is handled in the app\(checkout)\checkout-success\page.tsx file. The code retrieves the payment details from the Stripe Checkout Session and updates the database accordingly.

User Account Management

Stripe provides user account management functionality through the 'Customer Portal' (under Billing -> Portal). This allows users to self-manage their account and billing information.

When a user clicks 'Manage Account', the NextAppFast-generated code creates a Stripe Billing Portal and redirects the user to the Stripe-generated URL. You can find the relevant code in the app\(protected)\(admin)\account\_actions.tsx.
