What Does App Development Cost?
Having an app custom-built in Germany costs roughly €20,000 to well over €100,000 depending on scope: integrated process apps with their own backend around €30,000 to €70,000, complex platforms from €100,000 up. On top of that, plan for 15 to 20 % of the budget per year for maintenance. If you only need a standard process, ready-made SaaS from a few euros per user is often cheaper.
What do you get for which budget?¹ ⁶
There is no single app price. What matters is what the money buys: from which point you get your own code, your own integrations and data ownership. The ranges below are market guide values from around ten independent providers in the German-speaking market, not fixed prices.
| What you get | What drives the price | Guide value |
|---|---|---|
| Standard process covered, no custom build | Ready-made SaaS or no-code is enough functionally | approx. €3 to €300 / month (subscription) |
| Custom app, your own code, no deep integration | Own frontend plus a lean backend, data ownership | from approx. €20,000 |
| Integrated process app, production-ready | Connection to existing systems such as ERP and inventory, roles | approx. €30,000 to €70,000 |
| Customer or business app | Native iOS and Android, login, push, payment, own brand | approx. €60,000 to €100,000 |
| Complex platform | Multiple roles, scaling, many integrations, SLA | from approx. €100,000 |
What moves the price in a specific case is covered below in the section on how a price is formed.
Do you even need your own app?
Few providers ask this question, because the honest answer can cost them the job. Before you invest five figures, it pays to look at the cheap route: ready-made SaaS software or no-code builders.
For a standard process they are often the better choice: available immediately, from a few euros per user and month. A custom app is only worth it once the standard hits a hard wall at one of the following points. Any single criterion can be enough on its own.
| Criterion | Ready-made SaaS / no-code | Custom development |
|---|---|---|
| Does the workflow fit? | Only if your process follows the standard | Maps your real, deviating process |
| Deep integration into existing systems | Rare or only via expensive interfaces | Connects directly to ERP, inventory and machines |
| Data ownership and ownership of the code | Data and code sit with the provider (lock-in) | Code and data belong to you |
| Cost as you grow | Rises per user, tips over at approx. 80 to 100 users | One-off investment, independent of user count |
| GDPR, EU data location, sector rules | Depends on the provider, often limited | Freely implementable to your requirements |
| Entry cost | Very low, from a few euros per month | Five figures, but no per-user licence cost |
Rule of thumb: if the standard fits functionally, take SaaS. Only once fit, integration, data ownership, scaling or compliance hit a hard wall is the five-figure step to custom development worth it.
How is an app price actually formed?
What an app costs depends mainly on effort, and effort on technical depth, not on the idea. Modern apps are first and foremost backend projects: for complex apps up to a quarter of the budget goes into backend and interfaces alone, exactly the share most quotes underestimate. On security-critical projects such as the electronic health record I work on for IBM, this invisible effort is regularly larger than the visible user interface.
Behind the total sits a simple calculation: effort times day rate. The average freelancer hourly rate in the German-speaking market in 2025 is €104, around €830 per day. Senior specialists are at €90 to €130, agencies at €80 to €150 per hour. Doing that openly is more honest than a flat fee that hides the effort.
That is why prices vary so much: the same screen can mean 5 or 50 days of work, depending on what happens technically behind it.
The eight biggest cost drivers
- Number of platforms and native versus cross-platform: the single biggest lever. Two native apps cost 20 to 40 % more up front than one cross-platform solution.
- Backend complexity: data model, logic and interfaces, up to a quarter of the budget.
- Scope of features and integrations: payment, CRM, push, in-app purchases.
- Custom design instead of a template, and the number of screens.
- User and role systems with permission management.
- Security and compliance, GDPR above all.
- Offline mode and device features such as camera, GPS and sensors.
- Late scope changes: especially expensive because they touch several disciplines at once.
Three numbers worth knowing
Where does the money go in a project?
An app is more than programming. This rough split shows how the budget spreads across the phases. The more complex the app (multiple platforms plus backend), the more the share shifts towards backend and interfaces.
| Phase | Budget share |
|---|---|
| Concept and architecture | approx. 10 to 15 % |
| UI/UX design | approx. 15 to 20 % |
| Development (frontend) | approx. 35 to 50 % |
| Backend and API | approx. 10 to 30 % |
| QA and testing | approx. 10 to 15 % |
Experience-based and industry benchmarks from my own projects, not an official standard. The backend share grows with integration depth and the number of interfaces.
What does an app cost after launch?² ³
The purchase price is only the beginning. Anyone budgeting honestly calculates the total cost of ownership over several years: maintenance at 15 to 20 % of the development sum per year, plus hosting (approx. €100 to €200 per month) and store fees (Apple 99 USD per year, Google Play 25 USD one-off).
The three examples show the cost structure over three years. The build values are model assumptions for illustration, not market prices and not quotes.
| Example | Development (model) | Total cost over 3 years | SaaS comparison, 3 years |
|---|---|---|---|
| A: Internal process app with ERP integration (15 users) | approx. €35,000 | approx. €53,300 | approx. €5,800, but does not cover the special case |
| B: Customer service app, native iOS and Android | approx. €60,000 | approx. €89,100 | not possible with standard SaaS |
| C: Lean custom app | approx. €18,000 | approx. €28,500 | approx. €3,300 at 10, approx. €82,800 at 250 users |
With small teams, SaaS wins on paper; the crossover sits at around 80 to 100 users. Below that, a custom app is justified by fit, integration and data ownership, not by price. Important: over three years, running costs from maintenance and hosting reach nearly half the build price and belong in the budget from the start.
Which costs get overlooked most often?
The most expensive items rarely appear in the first quote. Planning for them early avoids a nasty surprise later.
- Late scope changes: any requirement that comes in late is considerably more expensive than at the start, because it touches design, frontend, backend and tests at the same time.
- Offshore rework: the cheap provider becomes expensive once the work has to be done a second time. A quality risk instead of a saving.
- Vendor lock-in: whoever has no access to code and data pays for every follow-up order on the provider's terms.
- Store setup and deployment: approx. €400 to €800 per store, plus the ongoing developer accounts.
- The cost of a failed app: by far the most expensive scenario. A clean discovery up front is the cheapest insurance against it.
Is there funding for app development?
Partly, but be careful with outdated tips. In Germany the federal programmes Digital Jetzt and go-digital are closed in 2026 and no longer accept applications.
What remains open are individual state-level digital grants. In Bavaria the Digitalbonus still funds until the end of 2027 (Standard up to €10,000, Plus up to €30,000, up to 50 % subsidy). Always check your own state's programme and the current status, these programmes change quickly.
As of June 2026. Funding terms age fast, please check before applying.
How do you cut costs without losing quality?
Saving does not mean saving on the developer. It means cutting the effort smartly. The most effective levers:
- Start with a focused MVP: first the core function that delivers real value, then expand based on real usage.
- Choose cross-platform where performance allows: one codebase instead of two saves 20 to 40 % up front.
- Clarify scope cleanly up front: most cost explosions come from late changes, not from the original plan.
- Begin with a paid discovery: a clear plan and a reliable fixed price before the first development day are cheaper than any mid-project correction.
My take
Take ready-made SaaS or no-code if the standard fits your process. It is cheap, instantly available and usually the right decision. I say that deliberately, even though I make my living from the opposite.
As soon as workflow, a needed integration, data ownership, scaling or compliance hit the standard hard, a custom app is worth the five-figure price. That is exactly what I build integrated process apps for, at a fixed price, from 19,999 EUR for a lean first build stage. The €30,000 to €70,000 mentioned above is the market range for the fully integrated version.
You do not have to go all-in straight away: an app check from 3,999 EUR classifies your project and delivers a reliable fixed price, a runnable prototype for 11,999 EUR makes your idea tangible in three weeks.
