It would be highly beneficial to me to be able to track how long the jobs take from estimate to invoicing as so that I can see which of my clients are the quicker decision makers and adjust future quotes for clients who take longer and require more adjustments and time spent. I am looking for a structure similar to the "time to pay" feature broken up into months so I can see at a glance who of my clients drag their feet and how new team members affect the time efficiency of the work completed.
