# Customer Blacklist
> Stop fraudulent and non-paying customers at the lane before they cost you another wash.
## Overview
Blacklisting a customer prevents their vehicles from being serviced at any of your wash sites. Use it to shut down repeat offenders: fraudulent chargebacks, non-payment, abusive behavior, or property damage.
When a blacklisted customer's license plate is scanned or entered at the POS, the wash is blocked and the reason you recorded is shown to your operator on the spot.

## Add a Customer to the Blacklist
### 1. Open the Customer Profile
Navigate to **Customers** from the left sidebar and select the customer you want to blacklist.
### 2. Click "Add to Blacklist"
On the **Account** tab, click the red **Add to Blacklist** button.
### 3. Enter a Blacklist Note
Enter the reason for blacklisting in the **Blacklist Note** field, then click **Blacklist Customer**.
The blacklist note is shown to operators at the POS when the customer's license plate is scanned. Write it so your team understands the situation at a glance.
***
## Active Members Cannot Be Blacklisted
A customer who has any vehicle with an active subscription cannot be added to the blacklist. This protects you from billing a blacklisted customer and the chargebacks that follow.
To blacklist an active member, first cancel every vehicle's subscription and set the valid until date to past. See [Manual Status Change](/memberships/manual-status-change) and [Valid Until](/memberships/valid-until) for the steps.
Attempting to blacklist an active member opens a modal explaining why the action is blocked. The blacklist note field does not appear until every subscription is fully wound down.

## What Happens at the POS
When a blacklisted customer's license plate is entered or scanned at the lane, the POS displays a **Blacklisted Customer** dialog with the note you recorded.
The operator can dismiss the dialog with **OK**, but the wash cannot be processed. The vehicle must be turned away or routed off the lane.

## Remove a Customer from the Blacklist
To restore service, navigate back to the customer's profile. The **Add to Blacklist** button is replaced by an orange **Remove from Blacklist** button along with a red **Blacklisted** banner showing the current note.
Click **Remove from Blacklist** and confirm. The customer is immediately eligible to be serviced again.
