In short
A custom web app with us starts from €2,000. That covers a focused first version: user accounts, a handful of screens, a database and one or two integrations. A smaller, website-style project (for example a calculator or a booking page) starts from €1,500.
The price grows with the number of screens, user roles and external systems. Native apps in the App Store usually cost several times more, because they have to be built and maintained for two platforms (iOS and Android).
What drives the cost of app development?
We look at the same six things on every project before we quote.
- Number of screens and features. A login, a dashboard and a form is a different size of project than thirty screens with reports and exports.
- User roles. If only you and your team use it, it is simpler. If clients, partners and admins all log in and each sees different data, permissions need to be designed and tested separately.
- Integrations. Invoicing, CRM, Google Sheets, XML or CSV product feeds, payments, email notifications. Every external system means extra work and extra testing.
- AI features. Text generation, document or photo analysis, an assistant. Agrider's valuation tool, for example, assesses a farm machine's condition from photos.
- Languages and markets. One language is simple. Agrider runs in 5 languages, each with its own URLs, which affects the structure, not just the translation.
- Platform. A web app that runs in the browser, or a native mobile app. We wrote a separate guide on this: Mobile app or web app?
Price ranges by project type
These are our starting prices in 2026. They are not a quote, but a starting point: we give you an exact, itemised price after a short call.
| Project | Typically includes | Starting price |
|---|---|---|
| Small, website-style app | calculator, booking, form with custom logic | from €1,500 |
| MVP, first working version | accounts, a few core screens, database, 1–2 integrations | from €2,000 |
| Client portal or internal tool | several roles, approvals, reports, notifications | custom, itemised quote |
| SaaS product with subscriptions | accounts, subscriptions, dashboard, AI features | custom, itemised quote |
| Native mobile app (iOS and Android) | App Store and Google Play release | discussed separately |
You will see much higher quotes for the same job on the market, especially from teams that hand-code everything. That is not necessarily wrong, it is a different way of working.
Why AI-assisted development is faster and cheaper
A large part of development is routine work: forms, lists, saving data, wiring up permissions. AI coding tools now do this much faster. Planning, the data model, security, testing and launch are still expert work, and we have a person check every change before it goes live.
An example from our own product: the first working version of DogDietLab took about two weeks with one developer. With a classic stack we estimate two to three months. Today DogDietLab runs in 24 regional versions, and a new feature typically goes from idea to live in two to four hours.
Fewer development hours show up directly in the price.
Costs to check beyond the quote
- Hosting. Servers, database, backups. Ask whether it is included or billed separately. With us, hosting, database and user accounts are included.
- Third-party fees. Payment provider fees, SMS, usage-based AI services. These grow with your traffic.
- Maintenance and new features. An app keeps changing after launch. Agree up front how much support is included and what a new feature costs.
- Data and content. Who uploads products, old customer data and copy? Migrating data from an old system is a separate line item.
- App stores for native apps. The App Store requires a paid developer account, and every update goes through store review.
Fixed price or hourly rate?
We give a fixed, itemised price. You know up front what the first version costs and exactly what is in it. When a new idea comes up during the project (and one always does), we price it as a separate item before we start on it.
With hourly billing it is harder to plan and easy to overrun. If you do work that way, ask for a weekly breakdown and a cap.
How to get an accurate quote
You do not need a finished specification. These five answers are enough for a first, realistic estimate:
- Who will use it? Your team, your clients, or both?
- What are the three most important jobs the app has to do?
- Which systems do you use today? Spreadsheets, invoicing, CRM, webshop.
- Does it need to work on phones, and does it need to be in the App Store?
- When do you need the first version, and what is the rough budget?
To see how a project like this runs from idea to launch, read the app development process step by step.
Frequently asked questions
Can we start small?
Yes, and we usually recommend it. An MVP, a working first version, shows what users actually use, so you only spend more on what works. More on this: MVP development: a working first version in weeks.
How long does it take to build an app?
A focused first version takes weeks, not months. Larger systems are built step by step, so there is something to try in the first weeks.
Is custom development worth it if ready-made software exists?
Not always. If your process is standard (invoicing, accounting, a simple webshop), ready-made software is usually cheaper. When custom software pays off is covered here: Custom software or off-the-shelf?
