Put a stage on every inquiry and the leak names itself
You cannot fix a pipeline you are counting in two numbers.
Most remodelers track inquiries received and jobs sold. Everything interesting happens in between. Record six stages instead: inquiry received, first contact made, measurement booked, measurement held, proposal delivered, agreement signed.
Counting them for one quarter usually ends the debate about where the business is losing money. Sometimes half of the inquiries never reach a live conversation. Sometimes measurements are booked well and half of them never get a proposal within a week. The pattern differs by shop and it is rarely what the owner assumed.
Record the drop reasons in plain words alongside the counts. Out of area, scope too small, price, timing, went with someone else, never responded. Six categories are enough and more than six will not be filled in consistently.
Give the reporting to one person and review it monthly. A pipeline board nobody owns stops being accurate inside three weeks.
