Does This Actually Pay for Itself?

Most clients recover their monthly fee from one extra booked job - sometimes less.

That’s where the calculator comes in.

Missed Enquiry Cost Calculator

If you’re missing calls or replying late, you’re leaking revenue.
This calculator estimates what those missed enquiries could be worth if you converted them at your normal close rate.

How many enquiries do you miss each month?

Missed calls, late replies to DMs, forms you don’t follow up, WhatsApp messages you don’t see.

Of the enquiries you speak to, what percentage becomes a paid job?

If 1 in 5 turns into work, that’s 20%.

What’s the minimum value of a typical paid job (£)?

Use the low end to keep this conservative.
