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. UI/UX design cost depends on product scope, user flows, screen count, research depth, prototype fidelity, design-system maturity, accessibility requirements, and handoff needs. We scope the engagement after reviewing the product, users, existing design assets, and required deliverables.
02
How long does a UI/UX design project take?
Project length depends on product scope, research depth, number of flows and screens, prototype fidelity, stakeholder review cycles, design-system requirements, and developer handoff needs. Milestones are agreed after discovery rather than applying one timeline to every engagement.
03
What is included in a UX review?
A UX review can assess priority flows or screens for usability, accessibility, information hierarchy, interaction friction, and conversion issues. Scope, deliverables, and review timing are agreed before the engagement begins.
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. Handoff can include Figma files with auto-layout, design tokens, interaction specifications, and direct designer collaboration during implementation, depending on the engagement scope. 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. We work primarily in Figma and apply relevant platform guidelines and accessibility requirements, including Material Design, Apple Human Interface Guidelines, and WCAG 2.2 AA where they fit the product and target users.
08
Do you sign NDAs before sharing project details?
We can sign mutual NDAs before detailed project discussions when requested. Confidentiality, access, source-file handling, and project information are then managed according to the agreed engagement terms.
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. Token migration, component documentation, and Storybook-ready handoff can also be included when they are part of the agreed design-system scope.
10
Which industries do you specialize in?
Our UI/UX work spans FinTech, healthcare, eCommerce, SaaS, logistics, EdTech, real estate, and gaming. Industry context, compliance needs, workflows, and user behavior are reviewed during discovery so the design approach fits the product.
