Your booking rate is the number of bookable calls that ended with a job on the schedule, divided by the number of bookable calls you received. It sounds simple, and it is, as long as you define "bookable" in writing and count it the same way every week. Most of the work in this guide is about that definition, because a vague one makes the rate meaningless.
This guide is written for owners and office managers who want to measure the phone before spending more on marketing or training. You don't need software to start. A sheet of paper by the phone works for the first two weeks.
Step 1: write down what a bookable call is
A bookable call is a person asking for work you do, inside your service area, that you could schedule within a reasonable time. Write that sentence on a card and adjust it for your business before you count anything.
Then list what does not count. A typical plumbing office excludes:
- wrong numbers, robocalls and sales pitches
- suppliers, vendors and job applicants
- existing customers calling about a job already booked
- requests for work you don't offer, such as a full renovation if you only do service
- callers clearly outside your service area
Everything else counts, including callers who were unhappy with the service fee, callers who said they'd "think about it", and callers who hung up on hold. Those are the calls that teach you the most. Leaving them out is the most common way offices flatter themselves.
Step 2: build a four-line weekly scorecard
The scorecard has four lines, and that is all it needs to start. Keep it the same every week so comparisons mean something.
| Line | What it counts |
|---|---|
| Total inbound calls | Every call, answered or not |
| Bookable calls | Calls that meet your written definition |
| Booked calls | Bookable calls that ended with a time on the schedule |
| Booking rate | Booked divided by bookable |
Add a fifth line once the habit is set: bookable calls that were missed or went to voicemail. That line tells you whether your problem is answering the phone or what happens once it is answered. The after-hours coverage workshop exists for offices where the fifth line is large.
Step 3: count for two weeks without changing anything
Before any training, count for two normal weeks. This is your baseline, and it only works if the team behaves as usual.
Here is what a baseline might look like for a small residential shop:
| Week | Total | Bookable | Booked | Rate |
|---|---|---|---|---|
| 1 | 58 | 37 | 22 | 59% |
| 2 | 63 | 41 | 25 | 61% |
| Two weeks | 121 | 78 | 47 | 60% |
Notice the two-week rate is calculated from the totals (47 divided by 78), not by averaging the two weekly percentages. With small numbers the difference can matter, so always add up first and divide once.
Step 4: turn the rate into dollars
A booking rate becomes useful when you can price a change in it. The formula is short:
extra jobs = bookable calls × change in booking rate extra revenue = extra jobs × average ticket
Take the shop above. It gets about 39 bookable calls a week, or roughly 170 a month. If coaching moves the rate from 60% to 70%, that is ten percentage points:
- 170 × 0.10 = 17 extra jobs a month
- 17 × $395 average ticket = $6,715 a month in extra work
Now do the same for a larger office with four CSRs, 520 bookable calls a month and a rate of 66%. A move to 72% is six points:
- 520 × 0.06 = about 31 extra jobs
- 31 × $450 = $13,950 a month
These are illustrations, not forecasts. Use your own average ticket from your invoicing system, and be careful to use revenue per completed job rather than your largest jobs. Then think about margin: extra revenue isn't extra profit, because the plumbers, parts and trucks still cost money.
Step 5: compare booking with marketing spend
Once you know the booking rate, you can see what the phone is doing to your advertising. Suppose you spend $3,000 a month on ads that produce 100 bookable calls. At a 60% booking rate you pay $50 per booked job. At 75%, the same spend costs $40 per booked job.
That is why we suggest measuring the office before buying more leads. If the rate is low, extra calls leak out at the same rate. Owners who want help on the marketing side can talk to Trades.Agency, our parent brand, but the order matters: fix booking, then grow volume.
Common mistakes that distort the number
These mistakes show up in almost every first scorecard we see. Avoid them and your number will be worth trusting.
- Dividing by total calls. Vendors and wrong numbers drag the rate down and hide real patterns.
- Leaving out "price shoppers". If they asked for work you do, they were bookable. The price conversations workshop helps with exactly these callers.
- Counting a callback as a new opportunity. One customer, one opportunity.
- Changing the definition mid-month. If you must change it, start a new baseline.
- Averaging percentages. Add the counts, then divide.
- Letting the person being measured do all the counting. Have a manager spot-check a sample each week.
- Ignoring seasons. A January freeze-up week and a quiet August week aren't comparable. Compare like with like, or track a rolling four-week rate.
Reading the number without overreacting
Small offices see big swings. If you get 30 bookable calls a week, two extra bookings move the rate by nearly seven points. Don't celebrate or panic over one week.
Look at the four-week trend, and pair the rate with a small weekly sample of scored calls. The score tells you why the rate moved. Our call scoring rubric gives you a simple way to do that, and the booking rate tracking service sets the whole routine up with you.
Booking rate versus close rate
Keep the office and the field separate. Booking rate measures whether the caller got an appointment. Close rate measures whether the appointment or estimate became paid work.
A low close rate with a high booking rate points to pricing, estimating or how plumbers present options. A low booking rate with a healthy close rate points to the phone. Mixing the two hides both problems. If both are low, start with the phone, because it is cheaper and faster to fix, and then look at the field.
A one-page checklist
Pin this beside the phone for the first month:
- ☐ Bookable-call definition written and agreed
- ☐ Exclusions listed
- ☐ Tally sheet or report set up
- ☐ Two-week baseline counted without changes
- ☐ Average ticket pulled from invoicing
- ☐ Missed bookable calls tracked on their own line
- ☐ Weekly four-line scorecard reviewed every Friday
- ☐ Four-week trend checked before any decision
If you want a second pair of eyes on your first scorecard, call, text or email. We will tell you whether the definition holds up. See services for how we help offices build the habit.
Frequently asked questions
Should missed calls count in the booking rate?
Yes, if the caller was likely bookable. A caller who rang out is still a lost opportunity. Track them on a separate line too, so you can see whether the problem is answering or booking.
What if a caller books on a second call?
Count the booking once, against the first bookable call. Otherwise the same customer looks like two opportunities and your rate looks worse than it is.
How long should we track before drawing conclusions?
At least four weeks. Weekly rates bounce around, especially in small offices, so look at the trend across a month rather than any single week.
Is booking rate the same as close rate?
No. Booking rate measures the office: callers who got an appointment. Close rate measures the plumber: appointments or estimates that became paid work. Track both, separately.
