You can utilize the Transaction Detail by Account report, Amy. I will guide you through the detailed procedure to customize this report, ensuring it aligns with your data requirements.
In QuickBooks Online, the Transaction Detail by Account report offers a detailed breakdown of your transactions with their corresponding information. This report can be configured to showcase sales/invoices by account where project invoices roll up.
Here's how:
