Time and billing on Excel

Hi all. I'm new to this forum. I'm experienced with Excel, but I'm not a power user. I'm trying to figure out whether Excel is a good solution for a simple timekeeping system. I need to track time in 15-minute increments spent on behalf of 7 clients. There are plenty of commercial products available on the market, but they are all overkill for my small business.

I envision a spreadsheet that includes pivot tables where I can select the start and stop times for each task. There would also be prompts for adding text details of the work performed. The results would feed an invoice that's also generated in Excel.

Is this reasonable and is there anything that's already been created that's currently available? I'm not sure where to look and would appreciate any input.

Thanks,
Rich

would the attached do what you want?

Robert, thanks for your response! Your file gets me part of the way there. I'm hoping to reduce the number of keystrokes so that when I keep my timekeeping on a second screen next to my laptop, it will be a very simple process to input my time along with comments (e.g., what I did during the half-hour that I billed). I'm going to play with what you provided to see how to make it work for me. Thanks so much for your help!!
