Hello there, @SV97.
QuickBooks Time only allows you to add time under a sub-customer (if there is any) as designed. However, if you need to add time for the main customer, you can follow the workaround I'll share below.
I recommend creating a new sub-customer using the main customer's name. Here's how:
- Open your QuickBooks Online company.
- On the left navigation panel, click Customers & leads.
- Go to the Customers tab. Then, click New customer.
- Enter your main customer's name. You can also add the necessary details.
- Tick Is a sub-customer.
- Select your main customer on the Parent customer dropdown.

- Hit Save.
Once done, you should be able to add time for your main customer.
