UI/UX design services for software products

UI/UX design shapes how a product looks and how easily people can use it. Stackvala designs software interfaces from user research to a tested prototype, so development starts with decisions already validated.

UI/UX design that makes software easier to use

UI/UX design is the discipline of deciding how software looks, feels and behaves. UX, or user experience, covers the whole journey: who the users are, what they are trying to do and how many steps it takes. UI, or user interface, is the visible layer: layout, typography, colour, components and motion. Together they decide whether people finish tasks or abandon them.

Good design is not decoration. It reduces training cost, support tickets and development rework, because problems are found in a prototype instead of in production. Stackvala’s design practice pairs user research with practical interface design, and we deliver files your developers can build from without guesswork, whether the build is with us or with your own team.

  • Product design for new SaaS, web and mobile applications
  • Redesigns of confusing or outdated interfaces
  • Design systems that keep large products consistent
  • Usability audits with prioritized fixes
  • Conversion-focused landing pages and onboarding flows
  • Accessible interfaces that meet WCAG guidelines

Where better UX pays off

Design investment is easiest to justify when you can connect it to a measurable result. These are the places we see the clearest return.

ProblemDesign responseMeasurable result
Users drop out during sign-upShorter flow, clearer copy, progressive disclosureHigher activation rate
Support is flooded with how-do-I questionsClearer navigation, inline guidance, better empty statesFewer tickets
Staff avoid the new internal toolTask-focused workflows tested with real usersHigher adoption
Features are built but unusedResearch to find real needs before buildingLess wasted development
Product looks different on every screenShared component library and design tokensFaster delivery, consistent brand

Our UI/UX design process

The process is deliberately light. We do enough research to avoid guessing, and no more.

  1. Research

    Stakeholder interviews, user interviews, competitor review and analytics where available.

  2. Define

    Personas, journeys and a prioritized problem statement.

  3. Wireframe

    Low-fidelity layouts to agree on structure and flow quickly.

  4. Prototype and test

    Clickable prototypes tested with real users, then refined.

  5. Visual design

    Typography, colour, components and responsive states.

  6. Handoff

    Design system, specifications and support during build.

Key points

What you receive

Deliverables are practical and organized for engineering.

User research summary

Insights, personas and journey maps in plain language.

Wireframes and flows

Every screen and state, including errors and empty views.

Interactive prototype

Clickable for stakeholder reviews and user testing.

Design system

Reusable components, spacing, colour and type rules.

Accessibility notes

Contrast, focus order and labelling aligned with WCAG.

Developer handoff

Assets, specs and annotated behaviors ready to build.

Design for accessibility and conversion

Accessibility and conversion are often framed as opposing goals. In practice they reinforce each other: clear labels, strong contrast and logical order help everyone, including people using screen readers, keyboards or small screens.

  • Semantic structure and headings that support assistive technology
  • Colour contrast that meets WCAG AA targets
  • Keyboard-friendly focus states and tap targets sized for touch
  • Plain-language error messages that explain how to fix problems
  • Forms that ask for only what is needed, with sensible defaults
  • Responsive layouts tested on real phones, tablets and large displays

Tools and collaboration

We work in the tools your team already knows, so feedback is easy and nothing is locked away.

PurposeTypical tools
Design and prototypingFigma, FigJam
Research and testingRemote interviews, usability tests, analytics, heatmaps
Design systemsComponent libraries, design tokens, Storybook
HandoffAnnotated specs, shared libraries, developer reviews

When design and development sit together, handoff problems largely disappear. Our designers work alongside engineers from web development and mobile app development so that what is designed is what ships.

In detail

Cost and timeline for UI/UX design

Design effort scales with the number of screens, the amount of research and the depth of the visual system.

We offer fixed-scope design sprints or an ongoing design retainer. Details are in our pricing models.

Product size

A handful of key flows is quicker than a full platform.

Research depth

Interviews and testing add time but reduce rework.

Design system scope

A reusable library takes longer and saves months later.

Number of platforms

Web, iOS and Android each need tailored patterns.

Stakeholder involvement

Quick decisions keep the schedule short.

What is the difference between UI and UX design?

UX design covers the overall experience: research, flows and usability. UI design focuses on the visual layer, including layout, typography, colour and components. Good products need both.

How long does a UI/UX design project take?

A focused design sprint can take a few weeks. Larger products with research and a design system take longer. We confirm timing after discovery.

Do you do user research?

Yes. We run stakeholder and user interviews, review analytics and test prototypes, scaled to your budget and risk.

Can you redesign an existing product without rebuilding it?

Often, yes. We can refresh interfaces incrementally, starting with the highest-impact screens, so you improve usability without a full rewrite.

Will the design be accessible?

We design to WCAG guidelines, including contrast, focus order, labelling and keyboard support, and we note accessibility requirements in the handoff.

Do you provide a design system?

Yes. A design system with reusable components and rules keeps the product consistent and speeds future development.

Can your designers work with our developers?

Yes. We deliver specs and files your team can build from, and we can support implementation reviews.
