Billing lives under Settings → Billing & transactions. The Plan card near the top shows whether you're on pay-as-you-go or a monthly plan, and it's where you switch, cancel, or resume a plan. Buy transactions — or Settings → Purchase — opens the in-app pricing page.
Buy transactions
Open the pricing page (Settings → Purchase, or Billing & transactions → Buy transactions), choose how many transactions you want on the Pay as you go card, and check out. It's a one-time purchase: nothing renews, and you don't need a plan. Checkout runs right in the app, takes promo codes, and is secured by Stripe — LetterScript never sees your card details. Transactions don't expire — and that's backed by our terms, not just this page: if LetterScript were ever discontinued, or ended your account through no fault of your own, unused transactions you bought one at a time are refunded (see the Transaction Credits section of the Terms of Service for the details). Every purchase emails you a receipt and is saved to Billing history (under Billing & transactions) for download.
Start a monthly plan
On the pricing page, choose Subscribe to Starter ($7 a month plus tax, 3 transactions added every month) or Subscribe to Pro ($20 a month plus tax, 10 transactions every month). Before the payment form appears, checkout shows the renewal terms and asks you to check a box agreeing that the plan renews automatically every month until you cancel — Continue to payment stays unavailable until you do. Plan checkout doesn't take promo codes.
Once the first payment goes through, the plan's transactions are added to your balance and you're taken to Billing & transactions, where the Plan card shows your plan, how many transactions it adds each month, and the date it renews. We also email you a confirmation with the renewal terms and how to cancel. Plan transactions go into the same balance as purchased ones, roll over, and never expire. Plan charges and the transactions a plan adds are non-refundable. You can have one plan at a time; you can still buy extra transactions whenever you like.
Switch between Starter and Pro
On the Plan card, choose Switch to Pro or Switch to Starter (the pricing page has the same buttons), then confirm.
- Starter → Pro happens right away: we charge $20 plus tax that day, add 10 transactions immediately, and your monthly renewal date moves to that day. You keep every transaction you already have, and nothing from your Starter month is refunded or credited.
- Pro → Starter takes effect at your next renewal. You stay on Pro until then and nothing is charged now; from that renewal on, we charge $7 plus tax each month and add 3 transactions. Until it happens the Plan card shows the scheduled switch, and Keep Pro cancels it at no charge.
Switching needs your plan to be in good standing — if a payment failed, update your card first.
Cancel or resume your plan
On the Plan card, choose Cancel plan and confirm. Cancelling takes effect at the end of your billing month: the plan stops renewing on the date shown, nothing more is charged, and you keep every unused transaction — they never expire. Plan charges are non-refundable, so cancelling doesn't refund the current month. Until that date the card reads Cancels with the date, and Resume plan turns renewal back on with no charge. A cancellation replaces a scheduled switch to Starter — the plan simply ends — but if you resume, that switch is back on: the plan renews as Starter, and Keep Pro appears again if you'd rather stay on Pro. Switching to Pro while a cancellation is scheduled also turns renewal back on, and the confirm says so. After the plan ends you're on pay-as-you-go, and you can start a plan again anytime.
Cards, receipts, and invoices
Everything stays in-app — no trip to an external billing site:
- Payment method → Update card swaps the card on file for future purchases and plan renewals (it reads Add card until there is one).
- If a plan renewal payment fails, the Plan card shows Payment failed with an Update card button. Update your card there to keep your plan.
- Billing history lists every purchase and plan renewal and downloads its invoice PDF.
- Transactions & storage shows what the workspace has used.
Opening a transaction spends one transaction for good, however you paid for it: deleting the transaction afterwards does not return the credit, so Archive anything you may want back.
