The missed call is the most expensive event in a pool sales week
A homeowner who reaches voicemail calls the next builder before you have heard the message.
Start by counting. Missed calls, calls answered after several rings, and calls that reached voicemail should be a tracked metric with somebody's name against it, not an unpleasant surprise.
Decide honestly who answers between eight and six, because the owner cannot both run a crew and be first to the phone. An answering service briefed on your trade, able to book a site visit rather than take a message, is worth more than most software.
Set a callback window in minutes for anything that slips through, and hold it. Response speed is one of the few advantages available to a small builder against a large one.
Record calls where permitted and listen to a handful each month. The reason inquiries die is almost always audible in the first ninety seconds.
