# Credits & billing

> How ParseRouter charges for document parsing.

ParseRouter uses a simple, usage-based model: you buy **credits** and spend them as you parse. No subscriptions, no per-seat fees – you pay for what you process.

## How pricing works

Parsing costs **1 credit per page**. A 10-page PDF costs 10 credits; a single image costs 1. The price is flat regardless of the document's content or complexity.

<Note>
  You're charged **only when a parse succeeds**. If a request fails – an unreadable file, a document over the page limit, or a temporary backend error – no credits are deducted. You never pay for a result you didn't receive.
</Note>

## Buying credits

Add credits from the [Billing](https://platform.parserouter.com/billing) page in your dashboard. Your balance updates as soon as the payment is confirmed, and credits don't expire.

## Checking your balance

Your current balance is shown on the dashboard. Before a parse runs, ParseRouter checks that you have enough credits for the document's page count – if you don't, the request is rejected with a [`402`](/concepts/errors)[ error](/errors) and nothing is charged.

## What counts as a page

| Input                           | Pages charged                    |
| ------------------------------- | -------------------------------- |
| PDF                             | One credit per page in the file. |
| Image (`.png`, `.jpg`, `.jpeg`) | Always 1.                        |

The page count for a PDF is determined before parsing begins, so you can predict the cost of any document from its page count.
