Why "it feels fine" isn't a real answer
Most owners have a rough sense of how often they miss calls, based on how the last week or two felt. That impression is unreliable — busy weeks feel worse than they measure, and quiet weeks hide the pattern entirely.
A real count, even a rough one, changes the conversation from a feeling to a number you can act on.
The method
For 30 days, log every call your business number receives: answered or missed, and roughly what the caller wanted if you can tell (new job, existing customer, something else). A notepad by the phone or a simple spreadsheet works — you don't need software for this step.
At the end of the month, count total calls and missed calls. That's your missed-call rate. Multiply missed calls by your average job value and you have a rough monthly cost — not exact, but real.
What to do with the number
If the number is small, you may not need to change anything. If it's larger than expected — which is common — the next question is simply whether a missed call gets any reply at all today, and how long that reply typically takes.
That's the specific gap a missed-call text-back closes: it doesn't reduce how many calls you miss, it makes sure every missed call still gets a fast reply.
