Payment Methods

Payment methods keep the subscription active and prevent service interruptions from failed billing attempts.

Before you begin

  • You need billing permission.
  • Use a business-owned card or supported bank account.
  • Make sure the billing page can load the secure payment form in your browser.

Where to find it

Go to Billing -> Subscriptions and use the payment method section.

Step-by-step

  1. Open Billing -> Subscriptions.
  2. Find Payment Method.
  3. Choose Add or Update.
  4. Complete the secure payment form.
  5. Save the payment method.
  6. Confirm the page shows the expected card or bank account ending digits.

What happens next

  • Waveline securely saves the payment method and stores the billing state returned by the payment processor.
  • The default payment method is used for future billing dates.
  • Invoices and subscription state update after payment processing confirms the change.

Best practices

  • Use a payment method that will not expire during a launch or porting window.
  • Update the card before the expiration month.
  • Limit billing access to admins who should manage payment information.

Troubleshooting

  • If the form fails to initialize, refresh and check browser privacy extensions.
  • If saving fails, verify card details and billing address with the issuer.
  • If the page shows no method after saving, reload billing data.
