Subscription & Billing
Billing & invoices
All billing runs through Polar. View invoices, update your payment method, and manage your subscription from one place.
Billing portal
Open the Subscription page and click Manage subscription. This opens the Polar billing portal, where you can:
- View and download invoices for past payments
- Update your payment method
- Cancel or reactivate your subscription
The Subscription page itself is where you start a plan, move between Pro and Business, switch billing cycle, see billing warnings, and watch usage against your limits under Plan usage. The portal handles payment, invoices, and cancellation; it doesn’t change plans.
Polar handles billing
formbase uses
Polar
for subscription management and payments. Your payment details are stored securely with Polar — formbase never sees your card number.
Switch billing cycle
Switch between monthly and annual from the Subscription page. Monthly to annual applies at once and bills the prorated difference; annual to monthly takes effect at the end of the year you’ve paid for. See upgrading & downgrading for details.
Which currency you’re charged in
formbase sells in US dollars, euros, Norwegian kroner, and Turkish lira. Your country decides which one you see and pay: Norway is charged in NOK, Turkey in TRY, the rest of Europe in EUR, everywhere else in USD. Each currency has its own price set independently — the figures are not exchange-rate conversions of the dollar price, so comparing them across currencies isn’t meaningful. AI credit balances stay denominated in credits whatever you’re charged in.
Invoices
Polar generates an invoice for every payment — subscriptions, renewals, plan changes, and AI credit packs. Download them from the billing portal for your records. All prices exclude tax.
AI credit purchases
Credit packs are one-time purchases, bought on the AI Usage page and processed through Polar. Each appears as its own line item in the billing portal. Purchased credits never expire. No plan includes credits, so packs are the only way to add them. See AI credits & usage.
Failed payments
If a subscription payment fails, Polar retries automatically. While it stays unresolved your account enters a grace period — full access to your current plan for 7 days, with warning emails along the way. Update your payment method in the billing portal and everything is restored immediately. A refund on a subscription payment starts the same clock.
Cancellation
Cancel from the Subscription page — Manage subscription opens the portal. You keep full access to your current plan until the end of the period you’ve paid for; there’s no immediate cutoff. After that, your account enters a grace period before Free limits apply. Deleting your account also cancels the subscription, so no charge is left running. formbase never deletes your data because of a plan change.
