# Usage & Billing

## Usage

On Vectrix, usage is determined by the total number of scans that you've run.\
\
There are **two types of scans** modes on Vectrix, **on-demand scans** and **monitoring scans**.

* On-demand scans each use one (1) scan out of your balance.
* Monitoring scans each use four (4) scans per day out of your balance.

{% hint style="info" %}
For Vectrix Community users, your scan balance will reset back to 10 scans every 7 days, starting on your account's initial creation.
{% endhint %}
