Currently, QuickBooks Online (QBO) doesn't have an option to set credit limits that automatically prevent the creation of invoices or orders, Jemma.
 
As a workaround, you can manually monitor your customers' balances and record their credit limits in the Notes field under their customer profile.
 
Here's how:
 
- Go to the Customer Hub and select Customers.
 
- Locate and choose the customer you want to manage from your list.
 
- Click Edit.

 
- In the Notes and attachments section at the bottom, type in their credit limit.
 
- Click Save.

 
 
You can also integrate with a third-party app to streamline your credit limit management process. To find and add an app in QBO, here's how:
 
- Click the My integration icon in the upper-right corner.
 
- Select + Find integrations.
 
- Use the magnifying glass bar or select the Browse categories dropdown to search for an app.
