How do I change a tier's price?

Nothing. Stripe prices cannot be edited once anything is subscribed to them, so flatpass makes a new price and retires the old one. Every live subscription carries on billing against the price it was created with — at the same amount, on the same date, indefinitely.

flatpass doesn’t move existing members onto the new price, in either direction. A member who switches billing period, or cancels and subscribes again, pays the tier’s current price for the period they pick. You can also change their subscription to the new price in your own Stripe dashboard: Stripe bills what you set, and flatpass follows it, revenue figures included. A price you make in Stripe yourself, rather than one of your tiers’ prices, is one flatpass doesn’t know, so it keeps that member on the price it last knew.

Each tier has a field per interval — weekly, monthly, quarterly, every six months, yearly. Filling an empty one adds that plan; clearing one retires it, so nobody new can buy it while members already on it keep their subscription. A tier has to keep at least one price.

Prices are entered once in your own settlement currency. Each save recalculates the amounts buyers in other currencies see, and those stay as calculated until your next edit.

A price change is an offer made to more people, so flatpass checks first that the tier’s Discord role is one the bot can actually assign right now. If it is not, the save is refused and the message names the role to move in Server Settings → Roles. Move it, reload the dashboard, and save again.

A plans panel posted by /flatpass panel is rewritten when you save, so the buttons in your channel show the new price without you posting it again. If flatpass can no longer edit that message, your dashboard says so under your tiers and asks you to post it again.
