FAQ

Frequently Asked Questions About UI/UX Design

Pricing, timelines, deliverables, and process answers for teams evaluating our UI/UX design work. Each topic covers scope, cost, and compliance in plain language.

01

How much does UI/UX design cost?

UI/UX design services pricing varies by scope. A design sprint starts at $8,000 for a single-feature problem. A SaaS dashboard redesign typically runs $25,000 to $60,000. Full mobile plus web product design ranges from $40,000 to $120,000 depending on screen count and research depth. Every estimate ships with a written scope document.

02

How long does a UI/UX design project take?

A landing page redesign takes 2 to 3 weeks. A SaaS dashboard runs 6 to 10 weeks end-to-end. Full mobile app design averages 10 to 16 weeks including research, prototyping, and developer handoff.

03

What is included in a free UX audit?

A 30-minute kickoff call, a written review of 5 to 10 priority screens, and a prioritized fix list covering usability, accessibility, and conversion issues. Delivery happens within 7 business days. The audit is yours to keep with no obligation to continue.

04

How do I choose a UI/UX design agency?

First, check three things: portfolio relevance to your industry, a documented design process, and direct designer access during the project. Second, avoid agencies that place a project manager between you and the designer. Finally, ask for a paid sample or audit before committing to a full engagement.

05

What is the difference between UI design and UX design?

UI design covers the visual layer including layout, color, typography, and interactive elements. In contrast, UX design covers the experience layer including user research, information architecture, and usability testing. Both are needed for a product that looks polished and works correctly.

06

Do you work with our existing development team?

Definitely. Our handoff includes Figma files with auto-layout, design tokens, interaction specs, and direct Slack access to our designers during the build. In addition, we can extend the engagement to include custom software development if you need additional engineering support.

07

Which design tools and standards do you use?

Figma is our primary design tool. We also work in Adobe XD and Sketch when teams require it. Every design follows Material Design 3, Apple Human Interface Guidelines, and WCAG 2.2 AA accessibility standards.

08

Do you sign NDAs before sharing project details?

Absolutely. We sign mutual NDAs before any commercial conversation begins. As a result, project details, source files, and business context stay protected through delivery and beyond.

09

Can you work with or rebuild our existing design system?

Of course. Our team extends existing systems, audits them for gaps, or rebuilds from scratch in Figma. In addition, token migration, component documentation, and Storybook handoff are all part of the standard process.

10

Which industries do you specialize in?

FinTech, healthcare, eCommerce, SaaS, logistics, EdTech, real estate, and gaming are our highest-volume verticals. Each industry has a dedicated design pod trained on its compliance, workflow, and user behavior patterns.
