Convert projects to Sub-customer

Welcome to the Community, dafish84.

To verify my understanding, are you saying your sub-customers changed into projects during the data migration and you'd like to change them back?

If so, you can convert or merge a sub-customer with an existing project.

Here's how:
 

1. In your left navigation bar, go to Projects.
2. Find a project you're working with.
3. Copy the name of your project.
4. Access the Sales menu and open your Customers tab.
5. Locate and open the sub-customer.
6. Click Edit.
7. From your Edit window, change the Display name to match your project's name.
8. When you're ready, select Save, then Yes to confirm the merge.

I've also included a few detailed resources about  using QuickBooks which may come in handy moving forward:

• Change sub-customers into projects
• Learn how features & data move from QuickBooks Desktop to QuickBooks Online

Please don't hesitate to send a reply if there's any additional questions or information you'd like to provide. Have a wonderful Monday!

I am not sure if they were sub-customers or projects in QBD, but in QBO, I have one customer (Madison Square, the name of my strip center) and all of the tenants are showing as projects and I would prefer for each tenant to be a sub-customer or Madison Square (customer).  I tried to create a new sub-customer by coping the name of the project like you mentioned and I get the following error, "Something's not quite right: A project is already using this name. Please use a different name"

Thank you for always getting back to us, @dafish84.

I understand that changing your tenants from projects to sub-customers is crucial for you. Although there isn't a direct way to convert projects into sub-customers, I have a solution that might help. You can modify the name of your project or add a marker to show it's inactive. After that, you can create a new sub-customer using the original project's name. 

Here are the steps to rename a project:

1. Go to Projects.
2. Select the project you wish to change.
3. Add a name in the Project Name option.

Once done, you can now add a new sub-customer.

Furthermore, it's not possible to use the same name for both your project and sub-customer, which explains the error you encountered. Also, there isn't an option to merge an existing project into a sub-customer.
