The monthly fee on a lead-generation directory subscription is easy to see — it's the number on the invoice. The number that actually matters, cost per won job, isn't printed anywhere. It only shows up once the fee is set against how many leads actually turned into paid work, and that's usually sitting scattered across a diary, a CRM and a bank statement rather than added up anywhere.

Two numbers, one real cost

Cost per lead is the fee divided by however many leads landed — useful, but it treats every lead as equally valuable, which they aren't. Cost per won job divides the same fee by however many of those leads actually became paid work, which is the number that reflects what a subscription is really buying. The gap between the two, and how it moves month to month, says more about whether a subscription is earning its keep than either number does alone.

A worked example

A £300 monthly fee, 20 leads received, 4 turned into jobs at an average £500 each: cost per lead is £15, cost per won job is £75, and that £75 works out to 15% of the average job's value — before materials or labour are accounted for. Whether that's a good deal or not isn't a fixed answer; it depends entirely on the margin on that £500 job, and what the same enquiries would have cost through another channel.

What this isn't

This works from whatever fee, lead count and win count are entered — it doesn't pull real figures from Checkatrade, MyBuilder, Rated People or any other directory, and it isn't a claim about what any of them charge or how their leads convert. Use your own bill and your own job log; the same maths applies whichever platforms are being paid for, and it's just as useful for comparing two subscriptions side by side as it is for judging one against a gut-feel sense of "is this worth it."
