# Billing, invoices and refunds
> Update your card, download PostOnce invoices, cancel your subscription, get a refund within 7 days, and fix a failed payment or an unexpected charge.
Billing is handled by Stripe. PostOnce never sees your full card number.
## Open billing
Click your name at the bottom of the sidebar, then **Billing**. The Stripe billing portal opens, where you can change your card, download invoices and receipts, update billing details, and cancel.
## Cancel your subscription
1. Click your name at the bottom of the sidebar, then **Billing**.
2. In the Stripe billing portal, choose **Cancel subscription**.
Your plan stays active until the end of the period you've paid for, then publishing pauses. Your accounts, workflows and queued posts are kept if you come back.
## Refunds
You can get a full refund within 7 days of a payment. Email [support@postonce.to](mailto:support@postonce.to?subject=Refund%20request) from the address on your account with the subject "Refund request".
## Why was I charged?
Open **Billing** and check the invoice. The usual reasons:
* **You chose yearly billing**, which charges a year in advance.
* **You changed plan**, which charges or credits the difference right away.
* **Your plan renewed** because the subscription wasn't cancelled before the renewal date.
If a charge doesn't look right, email [support@postonce.to](mailto:support@postonce.to) within 7 days for a refund.
## If a payment fails
PostOnce emails you and pauses publishing until the card is updated. Your workflows and scheduled posts are kept. Update your card under **Billing**, and publishing resumes.
Posts that missed their time while paused don't all publish at once. Review them under **Needs attention** on [Posts › Scheduled](https://postonce.to/dashboard/posts/scheduled).
## Still stuck?
Search this help center with ⌘ K, or email [support@postonce.to](mailto:support@postonce.to) from the address you use for PostOnce. Include the platform, the approximate time, and the exact message you saw. Never send passwords, access tokens, API keys, or card details.
