# How billing works

## Trial

When you create an account you get $20 of credit to use to test Call Fast.

You can track your credit usage in the sidebar or by clicking on your name at the bottom of the sidebar and then choose **Billing**.

## Pricing

Call Fast has a single pricing plan. We charge per minute pro rata [based on the country code you call](/faq/supported-country-codes-and-pricing.md). But we only charge if:

* The call is answered by a human.
* Or, if the call is answered by a voicemail and you set the project voicemail settings to "Leave message".

This means you are only paying for calls where something has happened.

## Billing

To upgrade and start paying for calls on a pay-as-you go basis click on your name at the bottom of the sidebar and then choose **Billing**. On this page you'll see a plan box. Click on **Choose Plan**.

When you do this, you'll be taken to a Stripe page to add your payment card details. Stripe is a secure payment processor which means that we never actually see or hold your card details.

Once you have successfully added your card details you'll be given a $20 payment limit. This means that we'll bill you:

* Each time your limit reaches $-20
* And/or on 1st of each month

We will then increase your limit automatically whenever you successfully make payment 3 times on each limit level. For example, when your limit is $20, when you hit this limit for the 3rd time we'll increase your limit to the next level.

This means your usage of Call Fast will grow with you and as long as your card payment is successful your account will always be active and your limit will grow with your usage.

If you need an increased limit or have any other billing related questions get in touch with us at <support@callfa.st>
