Two Ways to Get Paid for the Same Underlying Work
An appointment-setting vendor has to get paid for something, and the milestone chosen changes what actually gets optimized for. Billing on SQLs pays for a scoring outcome. Billing on booked, held demos pays for a specific, verifiable event: a real person on a real call at a real scheduled time.
Those are not two labels for the same thing. They are two different contracts about what counts as delivered work, and the difference matters more than it looks like on a pricing page.
What an SQL Is, and Who Gets to Decide When a Lead Becomes One
A sales-qualified lead is a scoring outcome, built from whatever criteria a marketing or revenue operations team defines, firmographic fit, engagement signals, form-fill behavior, then adjusted over time as that team refines its own model. That is not a criticism of SQL scoring as a marketing tool, it is a description of what the term actually is: an internal judgment call, not an externally observable event.
A vendor paid per SQL is, structurally, paid against a number that vendor and client can both influence through how the scoring rules get defined, which is a very different accountability structure than getting paid for something that either happened or did not.
What a Held Demo Is, and Why It Resists the Same Gaming
A held demo is not a scoring outcome. It is an event: a specific person joined a specific scheduled call at a specific time. That either happened or it did not, and there is no equivalent to adjusting the scoring model to make more of them count after the fact.
That is the entire case for billing on it. A held demo is a witnessed, binary event, which makes it a harder number to quietly inflate than a lead score built from criteria only one side of the relationship fully controls.
What the Cost Data Shows About an Unreliable Milestone
Median cost per SQL for B2B SaaS runs $762, median cost per MQL runs $198, split further into $162 for mid-market and $367 for enterprise, and median cost per closed-won deal from marketing-sourced pipeline runs $11,640, according to Directive Consulting’s 2024 benchmark data published via The Starr Conspiracy. That is a wide, escalating range between what an early-funnel milestone costs and what an actual closed deal costs, a gap that grows precisely because early milestones like MQL and SQL are the ones most subject to definitional drift between one team’s scoring rules and another’s.
A billing unit that sits closer to the closed-won end of that range, or at minimum at a verifiable, human-witnessed event like a held demo, is harder to quietly redefine than a scoring threshold sitting at the cheaper, earlier, more subjective end of it.
Why Contact Count and Deal Engagement Are Verifiable in a Way a Lead Score Isn’t
Gong Labs’ analysis of 1.8 million B2B deals closed in 2024 found that closed-won deals average roughly twice as many buyer-side contacts as deals that do not close, and that 77% of all deals are multi-threaded in some form. Those are independently, verifiably measurable facts about a deal, who showed up, how many people engaged, in a way an internally scored SQL label is not.
A held demo sits on that same verifiable side of the line. It is a contact event that either occurred or did not, countable the same way regardless of who is doing the counting.
What This Means for How a Vendor Should Get Paid
None of this argues that SQL scoring is worthless as an internal marketing tool, it clearly has a real, measured cost and a real, measured purpose inside a revenue team’s own process. It argues that a vendor’s billing unit should sit on the verifiable side of that line, not the scored side of it, since the two sides carry very different accountability built into them by default.
That is the actual argument behind billing per held, double-confirmed demo instead of per SQL: not that one number is bigger or smaller than the other, but that one of them is a witnessed event and the other is a judgment call.
