Billing
Payments for AMPER Flow are processed securely through Stripe. AMPER Flow never stores your card details directly.
Invoices
Section titled “Invoices”Every time a subscription is activated, you’ll get an email confirmation with a PDF invoice attached and a link to the hosted invoice. Ongoing invoices for renewals and license changes are managed the same way through Stripe.
To see your billing history or download past invoices at any time, use Manage billing on the Subscription page — this opens Stripe’s billing portal.
Managing your payment method
Section titled “Managing your payment method”Use Manage billing on the Subscription page to:
- Update your card or payment method
- View and download invoices
- Change plans or reduce your license count
- Cancel your subscription
Business buyers (tax ID)
Section titled “Business buyers (tax ID)”At checkout, you can indicate you’re buying as a business. This reveals fields for your company name and tax ID (NIP), and tax is calculated automatically based on your billing address.
What happens if a payment fails
Section titled “What happens if a payment fails”If a renewal payment fails, your subscription isn’t cancelled right away. Stripe automatically retries the payment over the following days, and your workspace keeps full access while retries are in progress — you won’t be locked out during this grace period.
To avoid any disruption, update your payment method as soon as possible via Manage billing. If all retries fail and the subscription is ultimately cancelled, your workspace admin is notified.
Cancelling
Section titled “Cancelling”Cancelling through the billing portal takes effect at the end of your current billing period — you keep full access to your plan until then, with no partial refund for the remaining time. There’s no separate “are you sure” flow beyond Stripe’s own cancellation confirmation.
