Product Qualified Lead (PQL)
A Product Qualified Lead (PQL) is a free or trial user who has experienced enough value in the product that they are likely to convert to paid. PQLs are defined by product usage behaviour, not just demographics or marketing engagement. They're the cornerstone of product-led sales — routing the right users to sales at exactly the right moment, dramatically improving conversion rates and reducing sales cycle length.
Note: There is no universal PQL formula — each product defines its own signals. Common signals: activated key feature, invited team member, created X items, logged in Y days in first week. Calibrate weights using logistic regression against historical free-to-paid conversions.
PQL-to-paid conversion rate > 20% indicates a well-calibrated model; SQL-to-paid is typically 5–15% by comparison
PQL conversion rate < 10% suggests your PQL definition is too loose — you're routing non-ready users to sales
Benchmarks by segment
How to improve PQL
Identify your top 3 activation signals through cohort analysis — which early actions most strongly predict paid conversion within 30 days?
Build a PQL scoring model in your CRM or product analytics tool and route high-score users to sales automatically
Create different PQL tiers: "warm" PQLs get in-product upgrade prompts; "hot" PQLs get direct sales outreach
Recalibrate your PQL model every quarter as your product and customer base evolve — what predicted conversion 12 months ago may not today

Frequently Asked Questions
An SQL is qualified by marketing/sales criteria: company size, industry, budget, decision-maker title. A PQL is qualified by product usage: the user has demonstrated, through their behaviour, that they get value from the product. PQLs have higher intent and typically convert at 2–5× the rate of SQLs because they've already experienced the product's value.
Yes — and this is the ideal scenario. When a user meets both the product usage threshold (PQL) AND the company profile criteria (SQL), they should receive the highest-priority sales outreach. These combined PQL+SQL leads typically convert at 30–50% rates.
