Subscription
Subscribe, change plan, fix payment, and view-only access.
Subscription is per Organisation. Owners open it from Setup (or from Billing by clicking a row).

Subscribe or change plan
Pick a plan and monthly or yearly billing. Checkout runs through Stripe using the Organisation’s default currency. If a WhoTookWhat trial is still running, Stripe saves the card now and starts billing when that trial ends (their page says Start trial for that reason). Stripe collects a billing address and calculates tax. Marketing pages still show “+ VAT” on en-GB, DE, ES, and FR; the charged amount comes from Stripe Tax.
An optional short voucher (letters and numbers, no vowels) applies a percent off for a number of months, or for the life of the subscription. Each code can be limited to named plans (for example Core only). Enter the code and click Apply to see the discount on the calculator; opening Subscribe / Upgrade again keeps that code. A 100% forever voucher on a listed plan activates it here without Stripe Checkout. Other vouchers apply at first checkout, not when you swap plan.
If this Organisation already has a Stripe subscription that can be swapped, WhoTookWhat updates that subscription instead of opening a second Checkout. A past-due subscription must be fixed first. An incomplete checkout can be started again.
Past due
If a payment fails, the Organisation stays on its plan for 7 days. A banner shows the deadline. After that, or if Stripe marks the subscription unpaid or cancelled, the Organisation becomes view-only.
You can still read the register. Adds, edits, and deletes are blocked until you subscribe or update the card.
Cancel
Cancel from the Stripe billing portal (opened from Subscription). Access continues through the period you already paid.
Transfer ownership
Owners can transfer this Organisation to a member who has already joined. The list only includes current members — invite someone from Members first if they are not there.
The member becomes Owner and can manage billing. You become Manager and lose Subscription. Stripe stays on this Organisation; the new Owner can update the card in the billing portal.
Trial ended
After the shared 30-day trial, every Organisation you created is view-only until that Organisation is subscribed. See Trial and plans.
