PQL trials convert 2.8× better; the analytics to score them starts free
What a product qualified lead is, how it becomes a sales qualified one, and the free event allowances at Amplitude, Mixpanel and PostHog, as of September 2026.
A product qualified lead is not an alternative to a sales qualified lead; it is the best way to make one. Gainsight reports that free trials using PQLs convert 2.8 times better than trials without them, and the product analytics needed to score them is free up to one to two million events a month at Amplitude, Mixpanel and PostHog.1 2 3 4 The 2023 version of this piece asked which of the two a business should use. The better question is where the line between them sits, and who draws it.
01A PQL is evidence; an SQL is a decision
A PQL is a trial or free user whose behaviour in the product matches what paying customers did before they paid: they invited a colleague, connected a data source, or hit a plan limit. An SQL is a lead a salesperson has accepted as worth a quote. One is measured by software; the other is a judgement by a person. A PQL that sales accepts becomes an SQL; one that sales rejects tells you the scoring rule is wrong.
02The one number, and why to discount it
It is the only PQL benchmark we could trace to a named report, and it comes with three caveats: Gainsight sells product-adoption software, the sample size is not published on the page, and the medians behind it sit behind a form. Read it as direction, not as a forecast for your funnel. Other figures in circulation, such as PQL-to-paid rates of 20% to 40%, come from vendor blogs without a method and are left out here.
03Scoring PQLs costs nothing until the first million events
Three product-analytics tools give 1 to 2 million events a month free, enough to score PQLs before you pay

Above the allowance the bill climbs with volume. TechBag’s Mixpanel page puts the overage at about US$0.28 per 1,000 events, or roughly US$1,120 a month at five million.4 Amplitude’s Plus plan “starts at $0” and prints no per-event rate.2 The cost of a PQL programme is therefore the instrumentation and the agreement with sales, not the licence.
04Buying in India
All three price in US dollars; through a reseller the invoice is in rupees with 18% GST added. Mixpanel offers an India data-residency option and has a Bengaluru office, which matters when the events are tied to a named user.5 That link is what makes trial behaviour personal data under the Digital Personal Data Protection Act, 2023. The DPDP Rules were notified on 13 November 2025, and the substantive duties, including the notice that must accompany a consent request, apply from 13 May 2027.6 7 Name sales contact as a purpose in the signup notice now. TechBag’s Mixpanel Product Analytics page sets out the plans against Amplitude and PostHog.
