Pay-per-lead marketplaces sell introductions. Professionals pay when a lead is delivered (or when credits are spent). Understanding incentives explains why two platforms with the same “lead” label can feel completely different.
The basic loop
- A client submits a request
- The platform validates or filters to some degree
- The lead is offered or sent to one or more professionals
- Professionals pay via credits, packages, or subscriptions
- Conversation and contracting happen mostly off-platform
Where platforms make money
Revenue usually comes from professionals (lead fees, ads, subscriptions), sometimes from featured placement. Client forms are typically free to maximize top-of-funnel volume.
The volume incentive problem
If a platform earns more when more leads are sold — including selling the same request repeatedly — quality can suffer unless counter-incentives exist: caps, verification, refunds, and review teams.
What “qualified” should mean
At minimum: real contact info, coherent project description, location, and some signal of budget or seriousness. Better systems add human review and category-specific fields (lot status, timeline, discipline needs).
How Acre & Angle implements PPL carefully
Acre & Angle uses credits for professional access, verification on intake, admin review before marketplace release, and capped distribution. Credits are designed to carry over rather than expire into artificial urgency. The company is an advertising/introduction layer — not the design firm of record.
