Direct Answer (Quick Summary)
Pay per lead means the contractor pays the agency a fixed price for each qualified lead delivered instead of a flat monthly retainer. Agencies set the price per lead from the contractor's average job value, close rate, and target marketing budget percentage. To prevent disputes, agencies define strictly in writing what counts as a valid lead and charge a modest upfront onboarding fee to cover ad risk.

How to calculate the price per lead
Use this standard mathematical formula to determine the ceiling price a contractor can afford to pay for an exclusive lead: Maximum Cost Per Lead = Average Job Value × In-Home Close Rate × Target Marketing Margin %
Worked Example (Roofing Replacement)
• Average Roof Replacement Job Value: $12,000 • In-Home Estimate Close Rate: 25% (1 in 4) • Contractor Marketing Margin: 10% Calculation: $12,000 × 0.25 × 0.10 = $300 maximum cost per lead. If the agency generates exclusive leads via Meta or Google Ads at $110/lead, the agency captures $190 in gross margin per delivered lead.
What counts as a valid lead (dispute-proof contract clauses)
To eliminate billing friction, your agency agreement must define a valid billable lead with precision: 1) Verified residential homeowner located inside designated service ZIP codes; 2) Seeking services the contractor actively provides; 3) Reachable via phone or email within 48 hours; 4) Not an existing customer or duplicate inquiry within the previous 60 days.
