The Freemium Model in SaaS: A Smart Acquisition Play or a Costly Gamble?


In the world of SaaS, the freemium model has become a widespread customer acquisition strategy. The premise is simple: offer a free version of your software to attract users and then convert a portion of them into paying customers. The classic tagline — "Start for free, upgrade as you grow" — perfectly encapsulates this approach.

But while the model sounds straightforward, the reality is more complex. Freemium is not just a pricing strategy; it is a calculated bet with significant costs. Companies must carefully balance acquisition, conversion, and infrastructure expenses to make freemium a sustainable growth engine rather than a financial sinkhole.

Freemium offerings come in different flavors, each designed to balance value for the user with a strong incentive to upgrade:

Unlimited free usage with restricted features

  • The core product is free, but premium features (often essential for corporate users) require payment.

  • This flavor is common in open-source solutions, where enterprise-level features—like advanced security, analytics, or integrations — require the paying enterprise version.

  • Often support is also only available for paying users.

Restricted free usage

Limited access based on:

  • User count (e.g. only three team members can use the free plan).

  • Usage caps (e.g. a maximum number of customers, transactions or storage space).

  • Feature limitations (e.g. watermarked outputs, no possibility to export, no publishing rights or missing integrations).

  • Time, i.e. often structured as a trial period (e.g. 30 days of access).

Ad-supported freemium

  • The product is free, but users see advertisements unless they pay to remove them.

  • This is closer to an ad-monetization model than a pure freemium approach since revenue comes from third-party advertisers.

Many assume that because SaaS products have low marginal costs, freemium models are nearly cost-free. However, this is a myth. Even with no physical goods involved, the total cost of freemium includes:

  • Infrastructure expenses: Every free user consumes server space, bandwidth and computing resources.

  • Support costs: Even non-paying users may need assistance, driving up customer service expenses.

  • Development and maintenance: Freemium features require ongoing updates, bug fixes and security patches.

  • Marketing spend: Since only a fraction of free users convert to paid, acquisition costs must account for those who never upgrade.

The industry benchmark conversion rate for freemium users to paying customers hovers around 5%. This means that the total cost per freemium user must be multiplied by twenty to determine the acquisition cost per paying customer. In high-cost SaaS businesses, this equation can become unsustainable.

Because of these high costs, SaaS companies invest heavily in optimizing conversion from freemium to paid. Some key tactics to drive conversions are:

Strong Engagement from Day One

  • Immediate onboarding emails, tutorials and in-app guidance ensure users experience value quickly.

  • Usage monitoring helps identify inactive users, prompting re-engagement efforts before they churn.

Reverse Trials: "Experience Full Value Upfront"

  • Users get full product access for a limited time and are automatically downgraded if they do not upgrade.

  • This works well when the product’s premium features create a strong "aha moment."

  • However, it can be costly in high-touch SaaS products requiring extensive onboarding and support.

Drive Investment of Users in the Product

  • The more effort and time users put into the platform (e.g. importing data, setting up workflows), the more likely they will convert.

  • Features that encourage deep engagement — such as templates, saved progress, and integrations — help create switching costs.

Gradual Conversion Tactics

  • Instead of pushing users to a full-price subscription, offer tiered pricing that increases over time.

  • Example: A company could start at $10/month for the first three months before transitioning to the standard $30/month plan.

Frictionless Upgrade Experience

  • Users should be able to upgrade seamlessly within the product — no complicated checkout processes.

  • A smooth transition from free to paid increases conversion rates significantly.

Personalized Offers Based on Behavior

  • Extended trials for highly engaged users who have not converted.

  • Usage-based discounts to encourage premium feature adoption.

  • In-app nudges highlighting the value of premium features at relevant moments.

Leverage Customer Feedback

  • Analyze why users do not convert and refine the offering accordingly.

  • If free users frequently mention missing features, consider adjusting the paywall strategy.

Ensure a Low Learning Curve

  • A freemium model only works if the product is intuitive and self-explanatory.

  • If users need extensive training to see value, a freemium approach may not be viable.

While freemium can be a powerful acquisition tool, it does not fit every business. It tends to fail when:

  • The product requires significant setup, training or support before delivering value.

  • Conversion rates are too low to justify the infrastructure and marketing costs.

  • Paying customers do not generate enough revenue to cover the cost of supporting free users.

In such cases, alternative strategies — such as free trials with credit card preauthorization, paid pilots, or high-touch sales approaches — may be more effective.

Clearly offering a freemium model is not just a marketing gimmick, but rather of sophisticated customer acquisition tool, which should be carefully planned and executed. By actively optimizing for conversion, minimizing free-user costs, and continuously refining the freemium offering, SaaS companies can turn "free" into a sustainable acquisition engine. However, if not managed correctly, freemium can become a black hole of expenses with little return.

Transforming the insurance sector to an Open API Ecosystem

1. Introduction "Open" has recently become a new buzzword in the financial services industry, i.e.   open data, open APIs, Open Banking, Open Insurance …​, but what does this new buzzword really mean? "Open" refers to the capability of companies to expose their services to the outside world, so that   external partners or even competitors   can use these services to bring added value to their customers. This trend is made possible by the technological evolution of   open APIs (Application Programming Interfaces), which are the   digital ports making this communication possible. Together companies, interconnected through open APIs, form a true   API ecosystem , offering best-of-breed customer experience, by combining the digital services offered by multiple companies. In the   technology sector   this evolution has been ongoing for multiple years (think about the travelling sector, allowing you to book any hotel online). An excelle...

RPA - The miracle solution for incumbent banks to bridge the automation gap with neo-banks?

Hypes and marketing buzz words are strongly present in the IT landscape. Often these are existing concepts, which have evolved technologically and are then renamed to a new term, as if it were a brand new technology or concept. If you want to understand and assess these new trends, it is important to   reduce the concepts to their essence and compare them with existing technologies , e.g. Integration (middleware) software   ensures that 2 separate applications or components can be integrated in an easy way. Of course, there is a huge evolution in the protocols, volumes of exchanged data, scalability, performance…​, but in essence the problem remains the same. Nonetheless, there have been multiple terms for integration software such as ETL, ESB, EAI, SOA, Service Mesh…​ Data storage software   ensures that data is stored in such a way that data is not lost and that there is some kind guaranteed consistency, maximum availability and scalability, easy retrieval...

IoT - Revolution or Evolution in the Financial Services Industry

1. The IoT hype We have all heard about the   "Internet of Things" (IoT)   as this revolutionary new technology, which will radically change our lives. But is it really such a revolution and will it really have an impact on the Financial Services Industry? To refresh our memory, the Internet of Things (IoT) refers to any   object , which is able to   collect data and communicate and share this information (like condition, geolocation…​)   over the internet . This communication will often occur between 2 objects (i.e. not involving any human), which is often referred to as Machine-to-Machine (M2M) communication. Well known examples are home thermostats, home security systems, fitness and health monitors, wearables…​ This all seems futuristic, but   smartphones, tablets and smartwatches   can also be considered as IoT devices. More importantly, beside these futuristic visions of IoT, the smartphone will most likely continue to be the cent...

PSD3: The Next Phase in Europe’s Payment Services Regulation

With the successful rollout of PSD2, the European Union (EU) continues to advance innovation in the payments domain through the anticipated introduction of the   Payment Services Directive 3 (PSD3) . On June 28, 2023, the European Commission published a draft proposal for PSD3 and the   Payment Services Regulation (PSR) . The finalized versions of this directive and associated regulation are expected to be available by late 2024, although some predictions suggest a more likely timeline of Q2 or Q3 2025. Given that member states are typically granted an 18-month transition period, PSD3 is expected to come into effect sometime in 2026. Notably, the Commission has introduced a regulation (PSR) alongside the PSD3 directive, ensuring more harmonization across member states as regulations are immediately effective and do not require national implementation, unlike directives. PSD3 shares the same objectives as PSD2, i.e.   increasing competition in the payments landscape and en...

Trade-offs Are Inevitable in Software Delivery - Remember the CAP Theorem

In the world of financial services, the integrity of data systems is fundamentally reliant on   non-functional requirements (NFRs)   such as reliability and security. Despite their importance, NFRs often receive secondary consideration during project scoping, typically being reduced to a generic checklist aimed more at compliance than at genuine functionality. Regrettably, these initial NFRs are seldom met after delivery, which does not usually prevent deployment to production due to the vague and unrealistic nature of the original specifications. This common scenario results in significant end-user frustration as the system does not perform as expected, often being less stable or slower than anticipated. This situation underscores the need for   better education on how to articulate and define NFRs , i.e. demanding only what is truly necessary and feasible within the given budget. Early and transparent discussions can lead to system architecture being tailored more close...

Are product silos in a bank inevitable?

Silo thinking   is often frowned upon in the industry. It is often a synonym for bureaucratic processes and politics and in almost every article describing the threats of new innovative Fintech players on the banking industry, the strong bank product silos are put forward as one of the main blockages why incumbent banks are not able to (quickly) react to the changing customer expectations. Customers want solutions to their problems   and do not want to be bothered about the internal organisation of their bank. Most banks are however organized by product domain (daily banking, investments and lending) and by customer segmentation (retail banking, private banking, SMEs and corporates). This division is reflected both at business and IT side and almost automatically leads to the creation of silos. It is however difficult to reorganize a bank without creating new silos or introducing other types of issues and inefficiencies. An organization is never ideal and needs to take a numbe...

An overview of 1-year blogging

Last week I published my   60th post   on my blog called   Bankloch   (a reference to "Banking" and my family name). The past year, I have published a blog on a weekly basis, providing my humble personal vision on the topics of Fintech, IT software delivery and mobility. This blogging has mainly been a   personal enrichment , as it forced me to dive deep into a number of different topics, not only in researching for content, but also in trying to identify trends, innovations and patterns into these topics. Furthermore it allowed me to have several very interesting conversations and discussions with passionate colleagues in the financial industry and to get more insights into the wonderful world of blogging and more general of digital marketing, exploring subjects and tools like: Search Engine Optimization (SEO) LinkedIn post optimization Google Search Console Google AdWorks Google Blogger Thinker360 Finextra …​ Clearly it is   not easy to get the necessary ...

Low- and No-code platforms - Will IT developers soon be out of a job?

“ The future of coding is no coding at all ” - Chris Wanstrath (CEO at GitHub). Mid May I posted a blog on RPA (Robotic Process Automation -   https://bankloch.blogspot.com/2020/05/rpa-miracle-solution-for-incumbent.html ) on how this technology, promises the world to companies. A very similar story is found with low- and no-code platforms, which also promise that business people, with limited to no knowledge of IT, can create complex business applications. These   platforms originate , just as RPA tools,   from the growing demand for IT developments , while IT cannot keep up with the available capacity. As a result, an enormous gap between IT teams and business demands is created, which is often filled by shadow-IT departments, which extend the IT workforce and create business tools in Excel, Access, WordPress…​ Unfortunately these tools built in shadow-IT departments arrive very soon at their limits, as they don’t support the required non-functional requirements (like h...

AI in Financial Services - A buzzword that is here to stay!

In a few of my most recent blogs I tried to   demystify some of the buzzwords   (like blockchain, Low- and No-Code platforms, RPA…​), which are commonly used in the financial services industry. These buzzwords often entail interesting innovations, but contrary to their promise, they are not silver bullets solving any problem. Another such buzzword is   AI   (or also referred to as Machine Learning, Deep Learning, Enforced Learning…​ - the difference between those terms put aside). Again this term is also seriously hyped, creating unrealistic expectations, but contrary to many other buzzwords, this is something I truly believe will have a much larger impact on the financial services industry than many other buzzwords. This opinion is backed by a study of McKinsey and PWC indicating that 72% of company leaders consider that AI will be the most competitive advantage of the future and that this technology will be the most disruptive force in the decades to come.

The UPI Phenomenon: From Zero to 10 Billion

If there is one Indian innovation that has grabbed   global headlines , it is undoubtedly the instant payment system   UPI (Unified Payments Interface) . In August 2023, monthly UPI transactions exceeded an astounding 10 billion, marking a remarkable milestone for India’s payments ecosystem. No wonder that UPI has not only revolutionized transactions in India but has also gained international recognition for its remarkable growth. Launched in 2016 by the   National Payments Corporation of India (NPCI)   in collaboration with 21 member banks, UPI quickly became popular among consumers and businesses. In just a few years, it achieved   remarkable milestones : By August 2023, UPI recorded an unprecedented   10.58 billion transactions , with an impressive 50% year-on-year growth. This volume represented approximately   190 billion euros . In July 2023, the UPI network connected   473 different banks . UPI is projected to achieve a staggering   1 ...
