  1. Choose a plan in a product's pricing section. This opens the /checkout page.
  2. Enter your email address. If you are a returning customer, you can sign in inline without leaving the page.
  3. Fill in your billing address so we can produce a correct invoice.
  4. Enter your card details. We accept Visa, Mastercard, Amex, and more, all secured by Stripe.
  5. Review any optional add-ons shown just before the payment button.
  6. Click Pay to complete your purchase.

Apple Pay and Google Pay appear automatically when your device supports them, giving you an even faster way to pay. After paying, you see a confirmation on screen and a receipt is emailed to you for your records.

Good to know: your card is handled and stored securely by Stripe for future renewals, and you can view or change it any time under Payment methods in your dashboard.
