A flexible price agreement gives the merchant full flexibility to charge the user any amount, at any time, and at any frequency. Unlike other agreement types, there is no maximum amount set or approved in advance by the user. This is ideal for services where both the amount and charging interval are unpredictable.

How it looks in the app
- Vipps
- MobilePay


Screenshot: Two-screen flexible price payment agreement sign-up flow in the app (Vipps or MobilePay) — the overview step shows Price and Frequency both labeled "Variable" with annotations noting the amount and timing can vary per payment and that no user-set maximum applies; the approval step shows a "Confirm payment method" prompt with a payment card and a Pay/Confirm button.
