Cost indication

What does it cost to have an app or web application built for your organisation?

An app for your customers or employees, a web application that brings a work process together, or a new partner for your existing app: answer a few short questions and you will see a first estimate of the cost and the lead time.

Question 1 of 7

It is 7 short questions; most people are through them in two to three minutes.

The estimate follows from your answers. It is an indication, not a quote.

What do you want built?

Pick what you want to end up with. If you are torn between web and app: a website or web application works fine on a phone too. A real app only becomes necessary when you need the camera, push notifications or use without internet.

A website we can update ourselves

This is the smallest option: pages, a contact form and an admin screen where you change texts and photos yourself. There is little logic in it, so the work sits mostly in the design and in filling it.

A web application people work in

Here the work sits in what the application does: entering, looking up, approving, reporting. Every screen is a piece of your process, and we have to get that process clear together first.

An app for phone and tablet

An app costs more than the same thing in a browser, and not only because of the building. You need a developer account with Apple and with Google. The app has to be signed and made ready for release. There has to be a store page with screenshots, a description and a privacy statement. Then Apple and Google check the app before it appears in the store. Every later update goes through that check again. That work is accounted for in the estimate.

Both: a web application and an app

Two shells on one system. The data and the logic are shared, but the screens get built twice and tested twice. And the app has to go through the stores: a developer account with Apple and with Google, signing and preparing a release build, a store page with screenshots and a privacy statement, and a check before anyone can download it. Every update goes through that check again. That is what the extra fixed amount and the extra days pay for.

I do not know yet

A perfectly good answer at this stage. We reckon with an average web application. In a first conversation this is usually clear within half an hour.

What determines the cost of an app or web application?

We do not quote a fixed price without knowing your situation: no two applications are the same. What it costs depends mainly on:

What the application has to do: the number of features, screens and process steps.
Who uses it: customers, employees or both, and which user roles and permissions are needed.
Where it runs: in the browser, on iOS, on Android or on all three.
Integrations with systems you already use, such as your accounting, planning or CRM.
Phone features, such as the camera, GPS, a QR or barcode scanner, notifications or working offline.
Security and privacy: which data the application processes and which requirements apply to it.
What happens after go-live: maintenance, updates and further development.

The clearer you are about what the first part has to do, the sharper the estimate.

The cost of a mobile app for your business

We build bespoke business apps for your customers or employees, for iOS and Android. We develop the traditional way, with the help of AI. Our developers decide the architecture, review what is generated and remain responsible for the quality. Read more about having a mobile app developed.

The cost of having a web application built

Think of a customer portal, an employee portal, a tool for planning or approvals, or a dashboard that brings together information from separate systems. A web application like that takes over the work of the spreadsheets, emails and exports that have quietly become business-critical. The cost depends mainly on the process you want to support and the number of integrations. Would an existing tool or a small change be enough? Then we will tell you so.

An example: for Transporting Highway we built a web application for planning and costing large-scale vehicle transport. View the case or read more about having a web application developed.

The cost of maintaining and managing your existing app

Do you already have an app or web application and are you looking for a partner for maintenance, management or further development? We can take it over, even if it was built by another company or a freelancer. For us, management includes monitoring, incident handling, updates, deployments and keeping the knowledge in-house. For mobile apps, publishing in the app stores is part of it.

What management costs depends on the state of the code, the documentation, the hosting and how much is still changing. That is why we start with an introductory conversation and an : we look at the code, architecture, dependencies, hosting and risks, and then make the cost of management and further development concrete. Your app keeps running throughout the handover. Read more about .

A limited budget? We will think it through with you

Do you have a fixed amount available? Then we look together at how to get the most out of it: which features deliver value straight away and what can wait until the application has proven itself. You can start small and build on what works.

How we work

Intake and analysis: first understanding what is going on.
Solution direction and design.
Developing and testing step by step.
Go-live and further development.

We work in short sprints and deliver working functionality each time. You see what is happening, decide what takes priority and keep control of your budget. JAM-IT was founded in 2016 and is ISO 27001 certified.

Who is this calculator for?

For companies and organisations that want an app or web application built for their customers, employees or processes, or that are looking for a partner for their existing application. Looking for an app for personal use, or want to build an app yourself? Then we are probably not the right partner.

Frequently asked questions about cost

Is the calculator's result a quote?

No. You get a first estimate. After that we look together at what your organisation needs.

Can we start small?

Yes. You can start with a clearly defined first part and then build on what works.

What does app maintenance cost?

That depends on the state of the app, the hosting and how much is still changing. We make it concrete after an introductory conversation and an audit.

Does our existing app have to be rebuilt?

Not necessarily. After the audit you know what can stay and what needs attention.

Do you build with AI?
