A defined qualified event. Not a retainer. Not a vague marketing package.
Depending on the campaign, the payable event can be a qualified inbound call, a qualified form lead, a booked appointment or another auditable outcome. The definition and price are agreed before traffic is routed.
The commercial event is explicit and measurable.
No standard monthly retainer and no invented universal lead price.
Routing only occurs where service area, hours, caps and qualification rules are agreed.
