FAQ
UI/UX Design Questions
Answers to common questions about design systems, UX strategy, audits, and prototyping.
UI/UX design services combine user research, interface design, prototyping, and usability testing to create digital products that are intuitive to use and aligned with business goals. UI design focuses on visuals and interactions, while UX design focuses on the overall user journey and product experience.
UI/UX design projects typically range from $8,000 for a UX audit to $80,000+ for full product design systems and multi-platform experiences. Pricing depends on screen count, research depth, and platform complexity.
Most UI/UX projects take between 4 and 16 weeks. Smaller UX audits may take 2–3 weeks, while enterprise SaaS platforms with full design systems can require 12–16 weeks.
UX design focuses on user flows, wireframes, information architecture, and usability, while UI design focuses on visuals, typography, colors, motion, and interface components. UX defines functionality; UI defines presentation.
Both approaches are used depending on the project. Design thinking is ideal for solving complex enterprise problems, while rapid prototyping works best for fast-moving startups validating ideas quickly.
