App Development as a Subscription: How App as a Service Works

App as a Service (app development as a subscription) is a model where you get complete development, operations and continuous improvement of your application for a fixed monthly fee — instead of a one-time investment of hundreds of thousands to millions of crowns. You don't pay separately for development, hosting and every change request. You pay one monthly amount and get a working, maintained and growing application.
In this article we'll explain how the model works, what it costs compared to the alternatives, what exactly the subscription includes — and, honestly, when it's not the right fit.
Why the subscription model exists at all
Traditional app development has a problem familiar to anyone who has ever requested a quote: the upfront investment. A decent mobile app from a Czech agency costs CZK 500,000 to 2,000,000. For most small and medium businesses, that number kills the project before it starts.
And the one-time payment isn't the end. An app is not a house — you don't build it once and walk away. Apple and Google ship new OS versions every year, libraries age, users want new features. Without continuous maintenance, an app genuinely degrades within two years.
The subscription model flips this: instead of a large upfront sum, you pay a predictable monthly fee that covers everything — development, operations and growth.
Comparison: subscription vs. agency vs. in-house vs. no-code
| Traditional agency | In-house developer(s) | No-code platform | Subscription | |
|---|---|---|---|---|
| Upfront cost | CZK 0.5–2M | hiring, equipment | low | CZK 0 |
| Monthly cost | maintenance billed extra | CZK 150,000+ per senior developer | thousands, grows with limits | from CZK 1,990 (web), from CZK 29,990 (mobile app) |
| What's included | only the agreed scope | depends on capacity | template features | development + hosting + support + new features |
| Growth after launch | every change = a new quote | yes, if the team has capacity | within platform limits | continuous, included |
| Vendor lock-in | low | none | high (data and logic live in the platform) | low — standard technologies |
| Best for | corporations with budget | companies with a permanent dev need | idea validation, internal tools | SMBs, startups, MVPs, long-term products |
Three notes that are usually missing from tables like this:
- An in-house team is not one person. For an app you need a mobile developer, a backend developer, a designer and someone to manage it. The realistic in-house cost is closer to CZK 300,000+ per month.
- No-code is not a scam. For validating an idea or a simple internal tool it's great. The problem comes the moment you need something the platform can't do — and you discover you can't leave, because your data and logic live inside it.
- Agencies are not the enemy. For large projects with a clear specification and budget, one-time delivery is a legitimate model. We offer it too.
What exactly the subscription includes
Different vendors define this differently, so let's be specific about how we do it. The monthly fee includes:
- Design and development — from specification through design to release on the App Store and Google Play
- Hosting and operations — servers, databases, monitoring, backups
- Maintenance — updates for new iOS and Android versions, security patches, bug fixes
- Support — when something breaks or you need advice, you talk to us, not a third-party ticketing system
- Continuous development — new features as your business grows
This is the biggest difference from one-time delivery: a subscription app has no "end of project". It grows with you. If you learn after six months that customers want a loyalty program, you don't write an RFP — we simply schedule it.
How is the fee calculated? By the scope of the app. A website or web application starts at CZK 1,990 per month; a mobile app for iOS and Android at CZK 29,990 per month. The configurator gives you an exact number for your project in two minutes.
The economics: why a CFO likes subscriptions
Cash flow. A startup with two million in the bank can either spend 60% of it on development, or pay a subscription and keep the money for marketing, operations and reserves. The same applies to established companies at a smaller scale — few owners enjoy signing a seven-figure invoice for something they haven't seen working.
Operating expense instead of investment. The subscription is a regular monthly cost — it goes straight into expenses, with no capital investment to depreciate. In accounting and in psychology, it's the same line item as rent or a software license.
Predictability. One-time projects have an ugly habit: change requests. The specification always shifts along the way, and the price with it. A subscription is fixed — changing requirements are a normal part of the model, not a reason for a contract amendment.
Aligned incentives. Less visible but perhaps most important: a subscription vendor only earns when the app works long-term and you're happy. There is no incentive to hand over the project, issue the invoice and disappear.
Who the subscription is for — and who it isn't
- ✗You have free capital and prefer a one-time expense
- ✗The app is single-purpose and won't change after delivery
- ✗You're building a tech company where development is a core competence — build an in-house team
- ✗You only need a small change to an existing app
- ✓A startup validating a product — you need an MVP fast without burning the budget
- ✓A small or medium business without internal IT
- ✓A product that will evolve continuously based on feedback
- ✓A company where the app supports the business rather than being its core (bookings, loyalty, internal processes)
To be direct: we offer both options. Every project can also be purchased one-time — prices are in our pricing. We recommend the subscription where it makes economic sense, not because it's the only thing we do.
Common objections (and honest answers)
"What if I want to quit?" You terminate the contract under the agreed terms. We don't do annual lock-ins with penalties — the model relies on the cooperation being worth it, not on you being unable to leave.
"Who owns the code?" Code transfer terms are agreed in the contract upfront — including a buyout option where you take over the app completely. No grey zone of "we'll figure it out when it happens".
"What if I want to take development in-house later?" You can. We build on standard technologies (React Native, Next.js, common databases) — no proprietary framework only our team can read. Handover includes code, documentation and access.
"Isn't it more expensive than buying outright in the end?" Let's do the math: an app for CZK 800,000 + 15% yearly maintenance = roughly CZK 1,160,000 over 3 years. A CZK 29,990 subscription × 36 months = CZK 1,079,640 — and that includes continuous development of new features, which maintenance contracts usually don't. The totals come out similar; the difference is risk: with a subscription you pay nothing upfront and can stop at any time.
Subscriptions and MVPs: a natural fit
Subscription development makes the most sense combined with the MVP approach — launching a minimum viable version of the product and expanding it gradually based on real feedback.
With one-time delivery, an MVP is paradoxically risky: you pay for the "small" version, and when the product takes off, every extension means a new RFP, a new quote and more waiting. The result is pressure to cram everything into version one — the most reliable way to burn the budget on features nobody uses.
On a subscription, iteration is the natural state. The first version ships within a few months, and features keep arriving based on what the data shows. You're not paying for a prediction of the future; you're paying for continuous delivery. We covered MVP planning in detail in How to plan an MVP for a startup.
What to ask a subscription development vendor
The model is still relatively new in the Czech market and offers differ significantly. Before you sign, insist on clear answers to these six questions:
- What exactly does the subscription include? How many development hours per month, what counts as maintenance and what is already a "new feature"? A vague answer means a future conflict.
- Who owns the code and what happens on termination? The answer belongs in the contract, not in an e-mail.
- What technologies do you build on? A standard stack (React Native, Flutter, Next.js…) means anyone else can take over development at any time. A proprietary platform means lock-in.
- What is the notice period and are there penalties? A fair model doesn't need annual lock-ins with contractual fines.
- Who handles operations — servers, monitoring, backups? "You arrange your own hosting" is not App as a Service.
- How are priorities planned? Ask for a concrete process (monthly planning, a backlog, a contact person), not "just write to us when you need something".
A vendor who answers these without dodging probably runs the model for real. A vendor who stalls is selling traditional development dressed up as a subscription.
How it works in practice
- Configurator or consultation — we clarify scope and tier (calculate your price, or book a consultation)
- Kick-off workshop — 60 minutes with a developer and a project manager; you get an MVP proposal and a tier recommendation
- MVP development — first version in 1–4 months depending on scope
- Launch and operations — deployment, App Store / Google Play, monitoring
- Continuous development — every month we move the app forward according to your priorities
The whole process is described in detail on How it works.

Summary
App development as a subscription (App as a Service) applies the logic of subscriptions to software: no upfront investment, one monthly fee covering development, operations, support and growth. For startups and smaller companies it's often the only way to afford a high-quality custom app at all — and for the vendor, a commitment that the app has to work long-term, not just on handover day.
