We are a professional services entity using QuickBooks Premier Professional Services Edition 2019 Pro (Desktop). We currently use a third party time reporting system to capture time details. Detailed time is imported into QuickBooks, but I cannot figure out how to create a summarized invoice (by item). When you click "Add Time/Costs" there is no time data. The invoice is imported directly into the invoice template. I would appreciate any guidance anyone would be able to provide. Do I need to import timesheets in versus into the template? Is there some way to modify the invoice template to include the ability to summarize the data?
