Kasra Dash and James Dooley break down how pay-per-sale lead generation works because businesses only pay once a job or product is successfully sold. Kasra opens by clarifying that unlike pay-per-lead or upfront advertising costs, pay-per-sale shifts all financial risk to the lead generation company. James explains that commissions depend on real margins because both sides must profit for the model to scale. They outline how pay-per-sale applies to services such as roofing, solar panels and conservatories as well as e-commerce products because any offer with predictable profit enables revenue sharing. The conversation highlights why knowing KPIs is essential because conversion rates dictate whether a commission structure is viable. Both emphasise that pay-per-sale partnerships work best when businesses have strong branding, reviews and sales processes because readiness determines acceptance into the model.
