How do I fix a open balance a customer has. Even tho I already billed them and it still says -$532.00

Thanks for joining the Community, josh-at-tnt-live.
 

Generally, a negative balance for a customer profile means there's credits of some kind applied to their profile. The negative open balance would reflect their credits on file.

Sometimes, this happens due to your Automatically apply credits option being turned off. The setting being off means you'd have to manually use their credits yourself. When it's turned on, QuickBooks will automatically apply them to the oldest open invoice for your customer.
 

Here's how you can check if the setting's turned on:
 

1. Use your Gear icon, then go to Account and settings.
2. Access the Advanced tab.
3. Find your Automation section and click its Pencil icon.
4. Review the Automatically apply credits setting and identify if it's currently turned off. If it is, you can turn it on if you'd prefer to.
5. Hit Save if any changes were made.
6. Select Done.

You can review our Create & apply credit memos article for more details about this setting.

If you feel these credits were entered invalidly and shouldn't be on your customers profile, I'd recommend working with an accounting professional before making any changes or removing them. If you're in need of one, there's an awesome tool on our website called Find a ProAdvisor.
