Stripe supports [125+ payment methods](https://stripe.com/gb/payments/payment-methods) around the world including: * Bacs Direct Debit * ACH Direct Debit * Mastercard * Visa * PayPal * Pay by Bank * Apple Pay ## Anniversary Billing (Based on Signup Date) We use **anniversary billing**, which means your subscription renews on the same day each month that you originally signed up. For example, if you join on March 12, your future bills will occur on April 12, May 12, and so on. Each payment is charged **in advance** and covers the upcoming month of access. This approach keeps billing predictable, avoids complicated prorating, and aligns with how most modern SaaS products operate. If you ever upgrade your plan, we’ll prorate the change immediately; if you downgrade, the new plan will take effect at your next billing date. ## Billing Customer Portal Find the link to your Stripe billing customer portal in the app under Team Settings.
