Kuba Masztalski: How to turn one-time service sales into recurring revenue

I don’t bind clients with any notice periods. If they don’t see the value – they can cancel the subscription overnight.

Kuba Masztalski is a solopreneur successfully combining automation, AI and business consulting in a subscription-based service model. Instead of traditional invoices and long-term contracts, he opted for flexible, trust-based cooperation with clients – and it works brilliantly.

From sales rep to solopreneur

Before going solo, Kuba worked in B2B sales as a sales rep and manager for 7 years. Even then, he was interested in technology and automation. The breakthrough came with the launch of the GPT API.

That was an eureka moment. The possibilities in business process automation jumped to a whole new level. I told myself: this is what I want to do.

Soon after, he started his own one-person business and began helping small and medium-sized companies design and implement automation and AI solutions. He operates as a one-man army – delivering services that he designs and executes himself.

The new way to selling services

Instead of the traditional “service — invoice” model, Kuba chose subscriptions. He knew that if he wanted to offer long-term services, he needed a model that would be convenient for both sides.

I figured that for this solo business to make sense, I needed to work in the form of ongoing cooperation, but through a flexible subscription. From the very beginning, I sold it using Easycart because of how simple it was to create products and how easy it was for clients to subscribe.

Many creators fear that clients won’t accept this kind of billing. Kuba had similar doubts – but reality turned out to be better than expected.

I had some concerns but this type of cooperation matches the nature of my services. That makes my clients – companies that had already reached a certain level of digitalization – accept it quite naturally.

Why no commitment wins commitment

The key element of Kuba’s model is flexibility. Clients can change the scope of cooperation or cancel it at any time. There are no notice periods, or rigid packages.

From the start, I clearly communicate that my main goal is to consistently deliver value and for the client to see steady progress. If that’s not the case, the client can stop the cooperation overnight or, for example, reduce the number of hours if their needs change. And this trust-based model works – I haven’t had a single case where a client subscribed and then suddenly canceled.

This model works especially well for clients already using cloud tools and familiar with subscriptions – like digital agencies or IT companies.

Digital products that fuel sales

After a year in business, Kuba decided to expand into digital products. The reason was simple – the market lacked dedicated materials for salespeople.

There were tons of AI training courses for marketers, but salespeople had nothing. When I was creating my course, English-language resources were available, but in Poland, there was nothing focused specifically on sales.

Since then, he’s been working on two fronts – creating free e-books as lead magnets and a paid course “SalesCyborgs”, which has already had two editions, with more planned. This way, before clients join the course, they can check the quality of Kuba’s offer by downloading the free e-book.

Our conversion rate on free infoproducts is around 40%. That might not seem like a lot, but the e-book was always meant as a first step toward paid products. Since users already provide their data to access it, Easytools stores it securely and makes future purchases super easy — they just click the link to the cart and their info is filled in automatically.

Fewer tools, more time

Thanks to Easytools, Kuba has all his sales, stats, and customer support in one place. It saves time and streamlines processes that used to require multiple platforms.

I use Easytools to offer lead magnets, sell and share the course, but also to collect testimonials and generate privacy policies. I have everything related to my business in one place – it’s super convenient and a huge time-saver.

Extra features like cart abandonment recovery or auto-generating waitlists make running a solo business really simple.

It’s a great ecosystem for a solopreneur like me. I can get a lot done that used to take several different tools. It’s a setup I feel good in — and it delivers real business results.

Will subscriptions work for you? Simple test

Kuba Masztalski shows that the subscription-based service model can be not only convenient for solopreneurs but also attractive to clients. It helps estimate recurring monthly revenue and eliminates issues with payment enforcement or invoice management.

Ask yourself the following questions to see if this approach could work for your business:

Business model and independence

• Can your services be delivered in a repeatable, long-term way?
• Do you care about stable, recurring income?
• Are you ready to give up contracts in favor of greater flexibility and trust-based cooperation?

Growth and revenue strategy

• Are your clients used to subscriptions?
• Can you flexibly tailor the scope of your services to client needs?
• Have you considered selling digital products as a service add-on?

Decision-making process

• Are you ready to move away from traditional invoicing toward automatic payments?
• Can you clearly communicate the value of your work in a subscription model?

If you answered ‘yes’ to most of the questions, that’s a clear sign it’s definitely worth giving subscription-based services a shot!
