After migrating to Simple Start from Desktop: is there a good way to make customers with unbilled billable expenses Inactive?

Thanks for reaching out here in the Community, mv2.

We need to delete all billable transactions associated with that customer to inactivate them in QuickBooks Online.

Here's how to delete the transactions:

1. Click Sales in the left panel and choose Customers.
2. Select the customer you want to inactivate.
3. Under Transaction List, find and open the invoice.
4. Click More at the bottom.
5. Hit Delete and click Yes.
   

Once done, we can then proceed with deactivating the customer. Check out this article for more information on adding and deleting customers in QuickBooks Online: Manage your customer list.

In the same link, we can find details about changing and managing customers' information as well as a short video to serve as your visual guide.

If you have any other questions about customer-related concerns, I'd be happy to assist you, mv2. Have a wonderful day.

Hi, mv2.

Hope you're doing great. I wanted to see how everything is going about inactivating customers. Was it resolved? Do you need any additional help or clarification? If you do, just let me know. I'd be happy to help you at anytime.

Looking forward to your reply. Have a pleasant day ahead!
