UX/UI DESIGN AGENCY For businesses that know that good UX/UI design is no accident.

The cost of UX/UI design depends on the scope, complexity and phase of the project. A UX audit or the optimisation of existing screens starts at around 5,000 euros. A complete UX/UI design project, including research, concept development, UI design and prototyping, costs between 15,000 and 50,000 euros, depending on the scope. Enterprise projects involving design systems and multiple product areas start from 50,000 euros and upwards.

The duration depends on the scope. A UX audit or a targeted optimisation project can be completed in 2–4 weeks. A full UX/UI design project, including research, wireframes, UI design and prototyping, usually takes 8–14 weeks. More complex projects involving multiple product areas or platforms can take 16 weeks or longer.

UX design (user experience) defines how a digital product works. It encompasses user research, information architecture, user guidance and interaction concepts. UI Design (User Interface) defines how a product looks. It encompasses visual design, typography, colours, icons and layout. Both disciplines work together to create digital products that are both intuitive and visually compelling.

A UX/UI design agency becomes essential when digital products fail to deliver the desired results, when users abandon the site, when conversion rates stagnate, or when a new digital product needs to be developed with a user-centred approach from the outset. Specialised UX/UI expertise is also valuable for relaunches, platform migrations or the introduction of design systems.

A UX audit is a systematic analysis of an existing digital product. It involves reviewing user guidance, information architecture, interaction design and conversion paths. The aim is to identify specific weaknesses and provide prioritised recommendations for action. A UX audit is usually based on heuristic evaluation, analytics data and best practices.

A design system is a collection of reusable components, design rules and documented patterns that ensure a digital product remains consistent. It includes typography, colours, spacing, buttons, form elements and interaction patterns. Design systems speed up development, reduce inconsistencies and facilitate collaboration between design and development teams.

Good UX/UI design has a direct impact on the conversion rate. Clear user guidance, logical page structures, straightforward calls to action and reduced friction in the interaction flow ensure that more users carry out the desired action. Studies show that every euro invested in UX can yield a return of up to 100 euros.

The European Accessibility Act has been in force in the EU since 2025, requiring many organisations to ensure their digital products are accessible. Accessible UX/UI design is based on the Web Content Accessibility Guidelines (WCAG) and includes, amongst other things, sufficient colour contrast, keyboard navigation and screen reader compatibility. At the same time, accessibility improves usability for all users.

Yes. UX/UI optimisations can also be carried out on existing products without a full relaunch. Based on a UX audit, the most significant areas for improvement are identified and implemented as a matter of priority. Often, targeted adjustments to navigation, page structure or conversion elements are enough to achieve measurable improvements.

The most commonly used tools in UX/UI design are Figma for interface design and prototyping, FigJam or Miro for workshops and concept development, and analytics tools such as Hotjar or Google Analytics for data-driven decision-making. For design systems, tools such as Figma with token management or Storybook are used.
