Pay Per Use is the future

If you’re like many business owners, there’s a question that may keep you up at night: “Is my pricing model right for the market?”

Instinct may tell you to follow your competitors. 

But then again, you also know that standing out amongst a crowd can propel your company into the limelight. 

You might even find that your competition uses several different pricing models, complicating things even more.

In many cases, you have two choices: the subscription model or the consumption-based model.

And the stakes are high. A poorly-judged or problematic pricing strategy can result in a serious loss of revenue. 

Yet, on the other hand, 98% of SaaS companies see success by making aggressive changes to pricing.

If you’re considering choosing between subscription and consumption at your company, you need a complete background.

This article will outline why a flexible consumption-based pricing model might just be everything you’ve been looking for, and also the four reasons why it might not be right for your company.

The Subscription Model vs The Consumption Model

When determining your SaaS pricing strategy, you’ve got a few different options to choose from. Aside from a one-off charge known as a Lifetime Deal (LTD), which arguably no longer positions your product as a SaaS, most pricing models use either the subscription or consumption-based model.

You also have the option of using a hybrid model that takes elements from both ideas. Let’s take a look at the difference between these two common SaaS pricing models.

What Is The Subscription Model?

In the subscription pricing model, customers pay a flat rate every month to access your software.

This is a model that has been used by SaaS companies for a long time now, growing more than 300% in the last seven years.

Many SaaS businesses (like Pipedrive below) that are using the subscription pricing model will opt to implement a tiered subscription model, which offers a few different subscription options with different features, and of course, different levels of pricing.

Using a tiered subscription model is advantageous because it gives your SaaS a lower entry point, with the opportunity to upsell in the feature. Many companies even go as far as offering the most basic version of their software for free, known as the freemium pricing model.

Like any pricing model, subscription-based pricing has its pros and cons…

One of the major benefits of this pricing model is that it allows both your company and your customers to budget easily, as the amount they pay is fixed each month.

A drawback for SaaS companies using the subscription pricing model is that high-usage customers may be getting more than their fair share out of the product (while low-usage customers may feel they’re not getting enough, and churn).

Picture a company whose overheads increase as customer usage does — for example, a cloud storage platform — and you begin to see how high usage customers on a subscription plan can have a major negative impact on your bottom line.

Still, the subscription model doesn’t appear to be going anywhere any time soon. In fact, by 2023, it’s estimated that 75% of all companies will be offering their product or service on some form of subscription-based plan.

But you have options. What about the consumption model?

What Is The Consumption Model?

In direct contrast to the subscription model, the consumption-based pricing model charges customers per unit of usage, rather than a fixed monthly rate.

It’s less common than the subscription idea, with around 38% of SaaS businesses opting for the consumption-based model.

For some subscription companies, pricing per single unit simply isn’t realistic. In that case, you might charge by hundreds or thousands of units. Take cloud storage giants like Microsoft Azure or  Amazon Web Services for example, who charge per million API calls.

If AWS were to charge per singular API call, the price point would be so low that it would simply be too difficult for potential customers to comprehend the value and the expected cost.

The major benefit of the consumption-based model is that it seems a fairer way to price. In this case, customers are paying for their actual usage, not simply their access to the platform, or for their potential usage.

It’s particularly beneficial for companies whose outgoings increase in direct relation to customer usage rates, such as the cloud storage example we mentioned earlier. In this scenario, the company is better able to manage their costs of operation, as they are covered by the ability to bill more accurately.

Why Flexible Consumption Model Based Billing Might Be Exactly What You Need

Consumption-based billing is best for companies that can accurately and easily break down their service offering into small, digestible chunks.

Examples include:

  • Utilities companies
  • Ridesharing
  • Marketing automation platforms
  • Clouding computing

In these examples, companies can easily determine a variable unit of usage.

Many companies have seen massive success using a consumption-based model. Take a cloud service company like Datadog, for example, who’ve been growing 88% year on year using a consumption pricing model.

By contrast, a SaaS such as a sales CRM platform might have a more difficult time quantifying the unit which can be charged for, as their product offering is so diverse and offers many different features.

There are, however, a number of drawbacks to the consumption-based pricing model. Let’s take a look at the four reasons the consumption model may not be the right choice for your company.

Why a Consumption-Based Model Might Be Wrong For Your Business

To inform this important business decision, the next couple sections will cover the pros and cons of the consumption model

Let’s get into it.

#1: Offering Annual Pricing Becomes Impossible

The first, and perhaps most obvious downside of the consumption-based model is that it prevents you from being able to offer an annual pricing plan.

For Subscription / SaaS companies, offering an annual plan is potentially one of the smartest pricing-related decisions you can make, as it locks customers into longer agreements, decreases your churn rates, and (through annual discounts) incentivizes conversion. 

Usage-based plans allow your customer to stop using your product at any time, essentially reducing your billables to zero.

In addition, many SaaS buyers actually want to sign up for an annual plan, because it makes billing easier, and (as we said) usually leads to a discount.

By not offering one, you might well be losing out to other companies who are, especially considering a massive 54% of SaaS firms have an annual plan as part of their revenue mix. 

#2: Revenue Is More Difficult To Predict

This is a huge challenge for SaaS companies of all sizes — whether you’re a startup needing to repay investments, or a growing company needing regular revenue to reinvest.

The problem with consumption-based pricing is this: you simply cannot predict what your monthly revenue is going to be, at least not very accurately.

Yes, you can make some assumptions based on historical usage data (which means you have to have been around long enough to have it), but there’s always the chance that a high-usage customer will experience a sudden drop in the need for your service, seeing your revenues for that month (or months!), plummet.

For many CFOs, revenue forecasting is done in monthly increments for the next financial year, looking at annual predictions after that. 

Using the consumption-based model, this becomes near impossible.

As well as not being able to confidently report to your board with regard to revenue forecasts, it also spells out a whole host of other issues.

Namely, the inability to make any solid decisions on reinvestment.

If you don’t know how stable your revenue is going to be over the next 12 months, it makes it really difficult to allocate funds towards new product developments or to sign off on that flashy new marketing campaign.

If you are going to use this model, make sure you take into account the volatility of your cash flow and forecast moderately. 

#3: Customers Are Paying In Arrears

Another major challenge presented by the consumption-based model is that you’ll be billing your customers in arrears.

Whereas subscription-based customers are typically paying for the month upfront, usage-based customers can’t be charged until the end of the month, when you know what their total usage for the period looks like.

For larger, more established Subscription companies with substantial cash flow, this might not be such an issue. For smaller companies, it can be a real nightmare.

We mentioned earlier that the kinds of SaaS companies that fit best with the consumption model are those whose overheads are tied directly to customer usage, such as in cloud computing, where the pay-as-you-go model makes sense.

Well, that means that if your customer usage goes up, then your bill goes up too. And most likely, your bill is going to be due before you’ve been able to gather all of the revenues from your own clients, meaning you’re shelling out before you’re raking it in.

Unless you’re well-funded, you may struggle to meet these obligations, putting pressure on those business relationships you’ve worked so hard to earn. It’s part of why 20% of startups fail as a result of choosing the wrong pricing strategy.

If you decide to embrace the consumption billing model, make sure you’re prepared to foot your bills in advance of receiving revenues.

#4: Clients May Find It Difficult To Budget 

While you may find it difficult to make revenue forecasts when your customers’ usage varies, they might also struggle to budget accurately.

With a subscription-based model, your customers know exactly what they’ll be paying each month. Even if they are paying by seat, they’ll know how many users they’re signing on for each month.

With the consumption billing business model, that pretty much goes out the window. Your clients will need to compute this budget  based on their expected usage, which of course will fluctuate.

Only 21% of businesses with more than 10 employees don’t budget regularly, so you can’t expect that this won’t be taken into account.

The risk?

They might decide to go with a competitor who offers a billing model that’s easier to budget for, maybe even an annual one.


The overall point is this: don’t go jumping into bed with a pricing model that seems right. Spend some time digging into what your competitors are doing, interview your customers and ask about their needs. A 1% improvement in pricing can mean an 11% spike in profits, so it’s worth investing the time.


With the pros and cons of a metered billing model laid out for you here, there’s not much more left to do than to perform your research and make a decision.

To recap, here are the four major dangers companies face when choosing a consumption-based billing model:

  • You can’t offer annual pricing
  • Revenue forecasting is more difficult
  • Customers are paying in arrears
  • Your clients might have a hard time budgeting
