For A/E firms labor is by far their largest expense. It would be foolish to not track it. It serves as the basis that helps answer questions like:
Who are my best clients?
What projects are the most profitable?
Who are my best employees?
And do they deserve a raise?
Am I charging enough to cover costs?
Any good project management accounting package will then take in all of this information and use it to process your billing seemlessly and efficiently. We have been doing this for over 20years. There is virtually nothing we haven’t seen.
