# Cancel Payment

{% hint style="warning" %}
**You should always cancel a payment if it will not be completed.**\
\
Whether the customer opts out, the cashier finds an error, or a set period of time passes without payment confirmation. This ensures your system stays accurate and clear of pending transactions that will never be paid.
{% endhint %}
