Billing refuses a change rather than doing something surprising with your money. Four messages, four different situations.
You already have a subscription
You already have a subscription.
You tried to start a new subscription while one is running, usually from a stale pricing tab. To move tiers, use the plan picker under Profile then Billing, which changes the existing subscription instead of creating a second one: an upgrade starts at once and you pay the difference, a downgrade starts at renewal.
Annual stays annual
You're on an annual plan and it stays annual. You can change tiers anytime.
Annual commitments run to the end of their term. Moving up a tier is open at any point and you pay the difference for the remaining term; moving down takes effect at renewal. What is not available is converting the remainder of an annual term into a monthly one mid-term.
Invalid pack size
Choose a pack of 500, 5,000, 25,000 or 100,000 credits.
Credit packs come in these four sizes only, the same everywhere: in the app, on the pricing page, in the API and through your AI assistant.
Finish setup first

Some workspace settings only exist once the platform is unlocked. Start the trial from any platform page, then return to the setting.

This one is on our side, not yours. Nothing was charged. Retry in a few minutes and, if it persists, mail support@argorant.com with the time you saw it.
Every successful change is documented under Profile then Billing with its receipt. We do not email receipts, so that page is the record.
