Create multiple projects per customer

Hello there, @ClemDac. 

Thanks for posting your concern here in the Community today. As an insight, the Projects feature is designed for only one customer that has multiple services. Hence, there isn't a way to create multiple projects for the same customer.

Instead, you'll want to consider adding new transactions to a project. You can add new transactions like invoices, expenses, or estimates directly into your project. Here's how: 

1. Select Projects, then select your project.
2. Select Add to project to create a new transaction.
3. Select Invoice, Receive Payment, Expense, Estimate, Time, or Bill.
4. Fill out details for the transaction like you normally would.
5. Select Save and close.

Consider having a project management app with more features to integrate with your QBO.
