What does a web application cost?
Updated: 2026-09
A web application costs different amounts depending on feature scope, design expectations and the number of integrations. A focused application on a modern stack is well suited to a fixed price; an extensive portal with many features costs correspondingly more. Binding range after a short first conversation.
"Web application" covers everything from a lean, focused tool to an extensive portal — the cost range is correspondingly wide. A single figure would therefore be of little help.
The factors below determine where your project sits. On a modern, proven stack, a clearly bounded scope can reliably be built at a fixed price.
What drives the cost
Number and type of features
The biggest lever: every additional feature and every user type increases the effort.
Design and bespoke work
A tailored design costs more than a functional standard interface.
Integrations and data
Connections to payments, external services or data sources increase complexity.
User and permission model
Login, roles and permissions are effort that is often underestimated.
Performance and SEO
A foundation built technically for speed and findability pays off but takes care.
How we price
- 01
Fixed price
Where the scope can be clearly bounded, we work to a binding fixed price. You know exactly what it costs before the project starts — no open-ended hourly billing, no surprises.
- 02
Time and materials against an estimate
Where the scope is not yet fully settled at the start, we work transparently against effort — with an estimate discussed in advance and regular cost control, so nothing runs away.
- 03
Engagement / retainer
For ongoing support — advisory, governance or continuous optimisation — we agree an engagement with a defined scope per month. Predictable cost, flexibly adjustable.
We deliberately publish no online prices: every case differs. After a short first conversation you receive a binding fixed price or clear frame.

Matching offers
Next.js web application at a fixed price
A bespoke web application on Next.js — fast, strong on SEO and maintainable, with a clearly bounded feature set and a binding fixed price. The result is a production-ready application without the usual cost surprises of open-ended hourly billing.
API & system integration
A clean integration connects your systems and third-party services so that data flows reliably — with idempotent processing, error handling and monitoring. The result is a connection that holds even when a target system goes down or an event arrives twice.
FAQ
Why is there no specific price on the website?
Because a serious price depends on the actual scope, and a number online would almost always be wrong — too high deters, too low leads to unpleasant surprises. After a short first conversation we give you a binding fixed price or a clear range.
How do I get to a binding fixed price?
Through a short, free first conversation in which we clarify scope, goals and constraints. On that basis you receive a specific, binding price — with no hidden costs.
What does maintenance cost after launch?
We discuss that separately and transparently — often as a small engagement. A cleanly built, modern stack keeps running costs low and keeps you independent, because you or your team can develop it further.
