"Lead quality guaranteed" appears in every second proposal — and is almost never spelled out. Here is our model taken apart: what counts as an irrelevant inquiry, how the criteria are fixed before launch, and where the boundary of an honest replacement runs.
Why pay-per-inquiry breaks motivation
When a contractor is paid for every inquiry, they have no reason to filter traffic: every contact is revenue, and sorting out quality becomes your sales team's problem. The "pay for a qualified inquiry, replace the rejects" model flips the motivation: an irrelevant inquiry becomes the contractor's cost, and filtering traffic becomes profitable for them. This is not a bonus feature — it is a different economics of the work, as we argued in "Lead or qualified buyer".
What counts as an irrelevant inquiry
The criteria are fixed in the contract before launch — not "by feel" afterwards. Our baseline list:
— the contact doesn't exist or doesn't answer after a series of attempts at different times and through
different channels;
— the person never left an inquiry and isn't interested in buying;
— the request is outside the segment: a budget several times below entry, a different destination,
rental instead of purchase;
— a duplicate of an inquiry already delivered;
— an inquiry from a competitor, an agent or a job seeker instead of a buyer.
Every point is a verifiable fact with a contact history — not a judgement call. Disputed cases are reviewed against recordings and logs.
Quality criteria fixed before launch are the only form of guarantee that can actually be verified.
How the replacement process works
Every inquiry passes scoring before handover — most rejects are filtered at that stage and simply never reach the invoice. If an irrelevant inquiry does get through to the sales team, the client has an agreed window to file for replacement. The claim is checked against the contract criteria; a confirmed reject is replaced with the next qualified inquiry — free of charge and without haggling. Replacement statistics are visible to both sides: a shared thermometer of traffic quality, not a battlefield.
The boundary: what is not a replacement case
Honesty works both ways. These are not replacement cases:
— a buyer who confirmed interest and budget but changed their mind after talking to a manager;
— an inquiry the sales team reached a week later, when the person had already bought elsewhere;
— "not our client" without a specific contract criterion broken;
— a deal that fell through in price or terms negotiations.
The guarantee covers the quality of the inquiry at the door — not the outcome of the sales team's work. That is exactly why it can be unconditional: the boundaries are known in advance and never move after the fact.
Frequently asked questions
How long do we have to file for a replacement?
The window is fixed in the contract — long enough for the sales team to process the inquiry. File as soon as the case appears: the fresher it is, the easier it is to verify against the logs.
What if the sales team just handles calls badly?
The statistics show it: when "rejects" are consistently not confirmed by call recordings, the issue isn't the traffic. We hand the buyer over warm, with conversation context — and help tune the speed and script of processing.
How is this different from pay-per-deal (CPA)?
Pay-per-deal makes the contractor answer for someone else's sales team, which is why it is almost never found in premium real estate in its pure form. Pay-per-qualified-inquiry is the working middle: the contractor answers for the quality of the input, the developer for converting it into a deal.
