Many of the fastest growing SaaS teams over the last 10 yrs have leveraged the concept of the PQL (Product Qualified Lead) but they rarely talk openly about it as it’s been a material competitive advantage for their Sales teams.

What is PQL?

A product qualified lead (PQL) is a lead who has experienced meaningful value using your product through a free trial or freemium model.

As a result, PQLs are more likely to become a customer than other leads. Unlike Marketing Qualified Leads (MQLs) which base buying intent on arbitrary factors like filling in a web form, downloading content, signing up for a newsletter or having virtually place items in the shopping cart, PQLs are tied to meaningful value.

Conceptually it’s based first on monitoring the user’s behavior (actions, clicks, etc) inside your SaaS product = “What (happened)”. Actions that match a pattern indicating readiness to buy.

Then you apply the “Who (is involved)” filter to see if they fit your Ideal Customer Profile

These leads can then be prioritized immediately to the top of your Sales team’s queue because they Act and Look like customers you have previously converted. With each new conversion you have more data to reverse engineer the most optimal buying process.

The much-needed middle ground

PQLs are much more powerful than MQLs 

Here are 4 reasons how:

PQLs are much more powerful than MQLs


If a product sells itself, and no hand-holding is required to convert a PQL into a paying user, then the company wins a “free” customer — one with little to no labor cost involved (apart from product development costs). You yourself are probably a “free” customer of many SaaS solutions — e.g., Netflix or Amazon Instant Video, your project management platform (Asana, Basecamp, etc), your doc service (Google Drive, Dropbox Paper), and the like.

Infinitely Scalable

Because PQLs require little to no human touch to convert, they’re scalable in a way SQLs — which require a dedicated rep to guide the buying process — can never be.

Highly Qualified

Redpoint VC Tomasz Tunguz found that when a human touch is needed, and sales reps do make calls to PQLs, those customers “typically convert at about 25-30%.”

This may happen because of the equally useful reverse effect: when sales reps qualify leads based on product usage data, they can unqualify leads much more effectively — as Appcues did, which allowed them to concentrate their small sales team only on the accounts most likely to close. 

Align the entire company

Finally, PQLs align outward-facing and inward-facing teams around the same goal: revenue.

As Tomasz Tunguz puts it:

“Typically, the product and engineering teams don’t have goals tied to revenue, which bisects a team into revenue generating components (sales and marketing) and cost centers (eng and product). Aside from potentially creating cultural challenges, this structure is less effective than it could be. PQLs pull product and engineering into the fray. Everyone in the company has the same goal.”

When you reach out to a PQL, they should have already experienced meaningful value in your product. This makes the sale easier because there’s no need to sell the user on the value of the product.

B2B Lead Funnel

Before we learn how to identify a PQL, lets see what PQLs are NOT:

First step in Identifying a PQL

To get started with PQLs you need to design an effective process of gathering data. To be able to do that you require a deep understanding of:

  • Who your users are
  • What they’re doing on your marketing site + inside your product
  • Why they were motivated to sign up
  • Which big goals they’re trying to achieve with your product

Without a clear understanding of these details, you’ll struggle to effectively personalize, segment, and craft experiences that convert trial users to paying customers.

To identify these details and begin setting up a strong PQL system, gathering and leveraging quantitative and qualitative customer data is key.

Quantitative data: trends in HOW people use your product

By collecting and leveraging quantitative customer data, you’ll be able to answer questions like:

  • Are your most successful users taking certain actions, while less successful users aren’t?
  • Do ideal users share common traits — goal with using your product, job title, industry, company size, stage of growth, etc?
  • Which actions and traits indicate long-term usage? Which indicate high value spend?

For example, Mixmax team knows that for a new trial user to get value from the platform — and eventually upgrade — she has to do more than simply click around her account, exploring the features available to her. To get value from MixMax, she has to actually integrate at least one of those features into her daily workflow.

“What we’re looking for,” says Olof Mathé, Mixmax CEO, “Is whether a user has actually used calendaring. Have they actually set up an automated email sequence? Are they actively using any email templates? Did they co-opt into Salesforce, or set up our Slack integration?”

Beyond this first action, a new user might take additional actions that hint at greater account value — like inviting team members to join Mixmax with her.


Qualitative data: trends in WHY people use your product

By collecting and leveraging qualitative customer data, you’ll be able to answer questions like:

What was so painful about users’ old lives that pushed them to seek out a solution like yours?

  • How did they discover you in their search?
  • Why did they trust your product, as opposed to other options?
  • What happened in their early days of use that convinced them “Yes, this is exactly what I needed”?
  • What event motivated them to take out their credit card?

This knowledge allows you to perfect your communication with PQLs, so your team can be as relevant and helpful as possible. As Emmaneulle Skala says:

“NEVER offer help if it’s not needed – There’s really nothing worse than ‘fake help.’ Please do not just say ‘I see you downloaded and want to learn more about your needs.’ If you don’t have any relevant context or reason to call, then don’t! In my experience, when there is no context it means the person is likely not going to convert or they’ll reach out on their own when they are ready.”

How to identify what a PQL is for your business

Product Qualified Leads can be a competitive advantage for your business. If defined correctly, you can align your marketing and sales team, close a high percentage of free users, and understand what prevents your users from becoming successful in your product.

PQL is for your business

As prospects utilize your application, they demonstrate buying intent based on product behaviors which can include:

  • Product interest
  • Number of users
  • Features used
  • Spending patterns
  • Usage patterns
  • Velocity – How fast a user or team is adopting your product

If you have a good history of product data at your fingertips, try looking for what behaviors closely correlate with users becoming paying customers. 

Although this process is time-intensive, you’ll be able to get a good handle on what behaviors are linked with users upgrading.

If you don’t have product data at your disposal, make sure to install a product analytics or product adoption platform to get a better handle on what behaviors link to users upgrading their accounts.

If you’re not getting into “machine learning” and complex modeling, an effective place to start is simply investigate who is logging into your product (let’s define this as “Engagement”).

Kinds of PQL’s 

Talking about PQL’s and Hubspot’s successful use of PQL’s VP of Marketing at HubSpot, Kieran Flanagan talks about developing 3 different kinds of PQL’s:

  • Hand-raise PQLs, which began as call to actions that were inserted at different points within the product to invite people to reach out and learn more about HubSpot’s paid products.
  • Usage PQLs (the most common type), which provide enough free product use to deliver value, but do not allow for ongoing use.
  • Upgrade PQLs, which require upgrades for access to gated features.

Set up a system for tracking your product data

It’s elementary: You have to track product data if you want to qualify leads based on product usage. We’re not talking about an extensive audit — just focus on events that are important for setting up a new account and events that are core to your product.

Define what makes someone a PQL 

Sherlock very effectively lays down the 3 steps to identify a PQL in their E-book – “Product Qualified Leads: What, Why & How”

Define Activation criteria for your product (and track it too!)

You don’t have a PQL until your lead gets the product set up and reaches “first value.” That’s called being “Activated.”

An exercise for you and your team to try :

Suppose you have a user (let’s call her “Sarah”) who sets up a trial so she could give your product a go. You gave her some breathing room — excellent. But how do you know when Sarah is “Activated”?

Grab a few of your team members (the more, the better) and ask them:

What are the three, four, five (maybe even six!) specific actions that allow a new account or user to experience “first value?” Is it inviting a team member? Creating a new workspace? Something that’s completely singular to your business? (Clue: If you’re an analytics tool your Activation criteria might be something like connecting data and creating a report.) 

These actions are your Activation checklist. And because you’re diligently tracking product data (you are, aren’t you?), you’ll be able to track Activation progress for each of your accounts. You’ll be able to answer questions like: How many of my five Activation steps has my latest signup completed? What is the average Activation rate for this month’s signups? 

Who should my sales team focus on?

Rank Activated trials by engagement

Create an engagement scoring model for your product and measure how engaged your accounts are. Compare them. Rank them. Look for trials that are not only more Activated, but also more engaged. The ones that are high on both axes are closer to being product qualified. The ones that are lower — not so much. This is how you can make a PQL spectrum. This is how your sales team can really start directing their actions intelligently.

A little tip: Creating an engagement scoring model is not a simple task. You’ll need to rank your product events based on how important they are and then keep tabs on the number of times each account uses your important features over time. Remember, “last active” and “login” are not acceptable substitutes for real engagement.

Do all of this at the account level

This is of the utmost importance. You’re a business. You sell to accounts — not just individual users. While a single user will sign-up for a trial, multiple users will work together to make the account “Activated” and engaged during the trial period. Multiple stakeholders in a company make the purchasing decision. 

So track the product data not just at the user-level but also at the account-level? It’s even more so when you’re tracking PQLs. PQLs are accounts, not users. You’re selling to accounts, your leads are accounts — you need to track accounts.

How to implement PQLs across the organization?

Once you have your PQL definition, you need to put the systems in place so that all teams can play an active role in generating more PQLs. This is not a solo sport. In this section, I break down some of the key metrics each team can be responsible for.


To keep marketing aligned on driving quality signups, these are the top two metrics that need to be prioritized:

  • Visitor to Sign up – Quantity Metric
  • Sign up to PQL – Quality Metric

When setting up metrics for teams, I always recommend having both a quantity and a quality metric to ensure that each team isn’t sacrificing quality in order to attain the quantity metric. As you can see with marketing’s metrics, they need to prioritize the Sign up to PQL conversion rate to ensure that the signups generated are top quality.


Sales is in a unique position to help users who have experienced meaningful value in the product decide which plan is right for them and offer additional support.

The quantity metric that sales is responsible for influencing is below:

  • PQL to Customer Rate – Quantity Metric

For the quality metric, there are a lot of different ways you can decide what is best for your business. Here are a couple options I’ve seen work well for B2B SaaS businesses:

  • Length of contract for each user
  • Average LTV per account

Regardless of what quality metric you choose, it’s important that it reflects that we’re upgrading users that become and stay as successful customers.


These metrics will help keep the product team aligned with delivering features and experiences that drive revenue. Having both a quantity and quality metric will ensure that the team is focused on driving the right kind of revenue through features.

  • Sign up to PQL – Quantity Metric
  • PQL to Customer – Quality Metric

Customer Success

Customer Success bridges the gap between helping both users and customers. As such, the team’s key metrics reflect helping users experience a meaningful outcome in the product and expanding accounts through upsells.

  • Sign up to PQL Rate – Quantity Metric
  • MRR Expansion Rate – Quality Metric


When it comes to monitoring the success of the free trial for the engineering team, these two metrics are helpful:

  • Sign up to PQL – Quantity Metric
  • PQL to Customer – Quality Metric

When engineers are responsible for key metrics that involve the product they’re building, I often find they can come up with brilliant ways to improve user adoption. If you’re a small organization, you can always start with one engineer who’s responsible for influencing these metrics and then involve more people as your organization grows.

What is Customer Acquisition Cost (CAC)?

Customer Acquisition Cost (CAC) is the total cost of sales and marketing efforts that are needed to acquire a customer. It is one of the defining factors in whether your company has a viable business model that can yield profits by keeping acquisition costs low as you scale.

If you have a successful business model your CAC will be sufficiently lower than LTV.

When you’re starting your SaaS company it can be tempting to get customers any way you can–regardless of the cost, time, and energy. However, if you plan on running a successful and profitable company you will need to balance the total cost of sales and marketing efforts that is required to acquire a customer or your Customer Acquisition Cost (CAC).

The challenge of CAC is: Spending the right amount to drive new customers to your service without jeopardizing the Lifetime Value (LTV) and revenue from that customer. This is known as the LTV/CAC ratio, and it’s the “god metric” of many successful SaaS companies. 

Successful SaaS businesses calculate CAC correctly and use that information to

  • quantify and optimize their marketing funnel. As well as understanding
  • mastering the balanced relationship that CAC has with LTV. 

Why is CAC Important?

Customer acquisition costs are a concern in any industry, but analyzing them is even more crucial to SaaS because the model depends on the lifetime value of the customer. To acquire new customers, most nascent SaaS companies devote a substantial amount of time and money before they see a full return on their investment. Examining just how many months of revenue from a customer are actually needed to recover these costs becomes essential as your business grows, as it may take much longer than you think for your company to recover CAC and actually begin to profit.

profit maximization

From a pricing perspective though, CAC is exceptionally important to keep in mind. When identifying high value customer personas and measuring their price sensitivity, you may find that customers with a high willingness to pay may be too costly to acquire and maintain, pushing you into a different part of the market. The flipside can be true too, where freemium acquired users may be putting a burden on your revenue model. Essentially, customer acquisition cost is the other side of the pricing equation, allowing you to completely understand what your margins, revenue, and profit will look like as you grow. Your success depends on knowing these numbers to circumvent the death of your business under the weight of its own inefficiency.  

How to Calculate CAC?

CAC is calculated by summing the marketing & sales spend for a given period and dividing that by the number of customers gained during that given period.

What forms the total sales and marketing spend? It’s any cost that you incur in acquiring a customer. It could be money spent on ad campaigns, events, cost of PPC campaigns, SEO, content marketing etc.

Note: Most people tend to miss out on some of the following points:

  • Cost of all tools used
  • Salaries of the marketing & sales teams
  • Referral costs
  • Overhead costs

Also consider: 

– If you have a freemium product, it’s important to add the product & support costs to the total sales and marketing costs too. This is because your product acts as your acquisition channel. 

– The number of customers taken into account should be your new paying customers that you acquired in that given period.

– Time Period

If you calculate CAC for just a month, it might not be the ideal measure of what happened in that month. Say you spent $20000 in the month of January but your revenue was $10,000 it’s not necessarily from this month. And the amount you spend now could be helping you in acquiring customers the following month.

It’s advisable to look at CAC over a period of time say 3 months.

How Do I Optimize My CAC?

1. Quantify your proper customer persona

Hundreds of articles have been written to help you define your customer personas. Yet, most of them fall short of a few 60 minute brainstorming sessions that culminate in some really pretty powerpoint decks, but very little traction into knowing your customer. As such, it’s crucial for you to quantify the range of customer personas you could serve as early as even the initial customer development process. 

You should know roughly the length of your sales cycle required for an optimal conversion rate, how much that customer is willing to pay and their price sensitivity, and even the proportion of those potential customers coming through your site. Furthermore, you should know what moves those customers to buy, what features they find most valuable, etc.

2. Optimize your funnel

Optimizing your sales and marketing funnel seems like one of the easier exercises for you to do, because you essentially have complete control over the process. Keep in mind though that optimizing for the wrong customer won’t do you much good in the long run, so make sure you focus on point one first. 

That being said, you need to quantify each step of the process, and also understand exactly how many visits lead to leads, how many leads lead to opportunities, and how many opportunities lead to customers.

Experimentation is key, but also keep in mind that you want to automate as much as possible. Hundreds of products exist to help in this effort (HubSpot, Help Scout, Salesforce, etc.). Find what works for you and what you need for each stage of your funnel and improve your efficiency as much as possible.

3. Experiment with pricing
If you have a freemium model, try experimenting with your pricing to figure out the factors which could lead to converting more paying customers. It could be an increased pricing tier, a feature based pricing model, seat based pricing etc. The more easily you are able to convert freemium users to a paid plan, the lower your CAC would be. But don’t compromise on customer happiness.

4. Strengthen the effectiveness of Sales and Marketing spend:

Take a lean approach to marketing and sales expenses. Put money into channels that have proven returns so that you aren’t wasting any more dollars. 

5. Quickly engage new customers and prospects:

Cut down the time it takes to get new customers engaged with your product. The quicker product engagement happens per customer the cheaper acquisition cost becomes per customer

6. Inbound Marketing:

Using real deal sweat equity to produce content that provides value for your audience is a great way to bring leads through your funnel at minimal cost to your business.

You know everything, but what now?

Unlike the marketing qualified lead which is typically determined between the sales and marketing teams, the product qualified lead requires all teams to work together.

One of the best parts about PQLs is that it aligns teams to focus on helping the user become successful in the product.

Embracing the PQL model, will result in you having more successful users and more upgrades as a result. 

It is  Win-Win situation.
