Worked example
How the number is worked out
A plumbing company with two vans. They answer most calls, but not all — nobody picks up while they are under a sink.
Starting from
Working
Somewhere between eleven and sixteen thousand a month walks past the phone. The band is wide on purpose — this is an estimate of a leak, not a count of one, and a tool that reported a single figure to the dollar would be pretending otherwise.
Optional later add-on if this leak keeps recurring
Start with The Desk if you still need something carrying the operating loop. Add Johnny later only if the narrower cancellation-recovery wedge is clearly worth paying for.
Johnny stays optional and should only come after the workspace already feels useful.
How this was calculated
Methodology v2026.01.1. These estimates are directional and depend on inputs and assumptions.
- Weekly missed calls × 4.33 to estimate monthly volume.
- Conversion rate estimates how many calls become customers.
- Average customer value drives revenue impact.
- Gross margin optional for profit impact.
FAQ
Why focus on missed calls?
Missed calls often represent high-intent leads that never get a second chance.
Are these estimates exact?
No. They are directional so you can see the size of the leak before refining assumptions.
Can I change the assumptions?
Yes. Adjust the inputs to reflect your business and rerun the numbers.
Why use a range instead of a single number?
Ranges reflect uncertainty and help you stress-test best and worst cases.
Does this include profit?
Use the gross margin input to translate revenue impact into profit impact.
