Most shops know they miss calls. Almost none know how many, or what those calls were worth. This audit fixes that in 30 minutes a month.
The missed revenue audit template below is a simple monthly review: you count the calls you missed, estimate what they were worth, track what you recovered, and watch the trend line move. Do it the first of every month, and you'll stop guessing about your phone problem and start managing it with a number.
You can run this on a napkin, but it's cleaner in a spreadsheet. If you already keep a call log, half the data is sitting there. If you don't, the first section tells you where to pull it from.
Grab these from last month before you start:
That's the whole input list. Everything else is arithmetic.
Fill these in each month. The template is deliberately short — six lines you'll actually keep up with beats a fifty-cell spreadsheet you abandon by March.
| # | Line item | Where it comes from | Example |
|---|---|---|---|
| 1 | Total inbound calls | Carrier/VoIP log | 420 |
| 2 | Missed calls | Total − answered | 68 |
| 3 | Miss rate | Line 2 ÷ Line 1 | 16% |
| 4 | Estimated lost leads | Line 2 × close rate | 68 × 0.5 = 34 |
| 5 | Estimated lost revenue | Line 4 × avg ticket | 34 × $350 = $11,900 |
| 6 | Recovered leads | Callbacks that still booked | 9 |
The example numbers are illustrative — plug in your own. But look at line 5. A 16% miss rate on 420 calls, at a $350 ticket and a 50% close rate, is roughly $11,900 in booked work that walked in a single month. That's the number that gets an owner to act. This is exactly the math behind how many calls the average garage door company misses — the audit just makes it yours, monthly.
If you want to build line 5 more carefully before you commit to the audit, the missed-call ROI calculator walkthrough walks the same math step by step.
Numbers tell you the size of the leak. This next step tells you where it is — and that's what you actually fix.
Once a month, break your missed calls into three buckets:
You don't need fancy analytics for this. Skim last month's call log and tally each missed call into one of the three. The bucket with the biggest pile is your priority. Most garage door shops find after-hours is the fattest one — and it's the one a live team can't cheaply fix.
The audit isn't just a guilt trip. Line 6 — recovered leads — is where you prove your fixes work.
Every month, count how many missed callers you actually called back and still booked. Then divide by total missed calls to get your recovery rate. If you're returning 9 of 68 missed calls, that's a 13% recovery rate, and 87% of the money is still gone. When you add coverage — a callback discipline, a shared inbox, an AI receptionist — this number should climb fast. If it doesn't, your fix isn't working.
Pair this with your morning missed-call recovery routine so the overnight misses actually get worked before the leads go cold.
One month is a snapshot. The value is in the trend. After three or four months of the audit, watch three lines:
If miss rate is climbing while you're spending more on ads, you're pouring lead-gen budget into a bucket with a hole in it. Fix the answering before you spend another dollar driving calls.
Here's the honest part. Once you've run this audit twice, you'll have a defensible monthly figure for missed revenue — usually four or five digits. Compare it to the cost of fixing the leak. A live CSR runs $2,500–$3,500/month and still sleeps at night. An AI receptionist answers every call, 24/7, captures name/phone/address/issue on each one, and sends you an instant summary — for a flat $297/month.
If your audit says you're losing $11,900 a month and mostly after hours, the math isn't subtle. Ava answers the calls your audit is counting as lost, and next month's line 5 shrinks. Run the audit, see the number, then decide.
