Add or change your payment method

The card on file lives in Settings, on Plan & billing. You can add one, or replace the one we already have.

1. Click Settings at the bottom of the sidebar.
2. Find Plan & billing.

This block is there on lifetime, and on a monthly or yearly plan. It is not on the 30-day trial you started with your card, which already has it.

If you have no card yet

• It says No card on file. Add one to buy extra client workspaces.
• Click Add a payment method.
• Card details go straight to Stripe. They never touch our servers.

If a card is already on file

• Brand, last four digits, and expiry.
• Update payment method replaces it.
• A line under it names what it pays for: your plan, Business Max, your extra client workspaces, or more than one of these.

If something is wrong

• Expired: the row turns amber. This card has expired. Replace it or your next workspace charge will fail.
• On file but we cannot charge it: We can't charge this method yet. Add it again below, or email support@booksgpt.ai.

If you have an unpaid invoice

Saving a new method discloses this first:

• Saving this card will also let Stripe retry your unpaid invoice of $X.
• If we cannot name the amount: Saving this card will also let Stripe retry the unpaid invoice on your account.

Extra client workspaces

• Buying an extra workspace needs a card on file.
• With no card yet, click Add client workspace under Extra client workspaces. When your plan's workspaces are used up, BooksGPT asks for a card as part of creating the new one, and shows the charge before you confirm. Your current plan stays the same.
• A free-forever founding account with nothing billed has no Payment method block. It adds a card the same way.

Good to know

• Yearly back to monthly is still email support@booksgpt.ai. That is not a card change. See "Pay monthly or yearly".
• Cancel is on this same page. See "Cancel a trial or monthly plan".
