This page covers the volume trades: cleaning, lawn care, pressure washing, junk removal, handyman work, pest control. Tickets are smaller ($150 to $600 for most first jobs), which means the first-transaction math looks thin next to HVAC or roofing. The trades in this bucket that win at paid lead generation all win the same way: repeat schedules.
A one-time $250 clean at 50% margin carries $125 of profit; a biweekly customer at the same rate is worth $3,000 a year. Pest control figured this out a generation ago, which is why national pest brands can pay $80 for a lead that a one-off exterminator cannot justify at $30. The recurring-revenue toggle in this calculator is the whole story for this category; run your numbers both ways and the difference is your answer about whether to sell subscriptions harder.
Lead quality varies more here than in the licensed trades because the barrier to entry is low and marketplaces aggregate everything. Shared leads sold to four competitors close at a fraction of exclusive-lead rates, so a $25 shared lead closing at 10% costs more per customer ($250) than a $60 exclusive lead closing at 35% ($171). Cost per customer is the honest comparison; the calculator's math surfaces it directly.
Worked example
A worked example: a cleaning company averaging $450 first jobs at 50% margin keeps $225. At a 35% close, a lead carries about $79, and the divide-by-three ceiling is roughly $26 on first-job math. Count regular repeat (the dataset's 3.0x multiplier for this category) and the ceiling rises to about $79, which is the difference between avoiding paid leads entirely and buying them profitably.
The marketplace caveat: aggregator leads are shared with competitors by design, and the race goes to the first responder within minutes. If your operation cannot respond inside five minutes during business hours, exclusive lead sources at higher sticker prices will produce cheaper customers.
