Accept payments in your app

When you build payments into your app’s code: three payment providers compared, what you need to sign up and which key goes where.

  1. Extension: take payments

    With the provider

    Time: ≈ 20 minutesCost: no base fee, a fee per payment

    1. Your Geckify app runs without it. You only need it once you or a developer build payments into the code.
    2. Create a Stripe account and complete identity verification — have an ID and bank details ready.
    3. The publishable key goes into the app, the secret key only into the host.

    Three reputable providers — your choice

    • Stripe

      Free: no monthly fee

      Then: EEA cards 1.5% + €0.25, subscriptions add 0.7%

      you are the seller and handle the tax
    • Mollie

      Free: no monthly fee

      Then: EEA cards 1.80% + €0.25

      Dutch provider with many local payment methods
    • Paddle

      Free: no monthly fee

      Then: 5% + $0.50 per payment

      Paddle is the merchant of record and pays the VAT; software only, review takes 5–7 business days
    As of 23 Sep 2026; prices may change. Geckify earns nothing from any of these recommendations.
