Frequently Asked Questions

What services does a UI/UX design agency typically offer?

A UI/UX design company typically helps organizations plan, design, and validate digital experiences for mobile apps, websites, and software products.  

Core UI/UX design services include:

  • UX audit
  • User research and analysis
  • Design systems (visual components, standards, governance) 
  • Interaction Design (IxD)
  • Information architecture 
  • Wireframes and prototypes 
  • User testing

Many also offer design consulting, cross-platform experience design, content writing, branding, and development.

How long does it take to complete a UX design project?

A UX design project takes about 4-6 weeks for a simple digital design with minimal functions and features. In contrast, an enterprise build or SaaS app can take over 20 weeks due to scale and complexity. 

The final timeline will depend on the complexity of your digital design, features, and functions, development method (Agile or Waterfall), feedback loop, and existing user data. Below is an estimated timeline of the UX process: 

  • Discovery and UX research: 1-4 weeks 
  • Information architecture and user flow: 2-6+ weeks 
  • Wireframing and prototyping: 3-5+ weeks 
  • Usability testing: 2-4 weeks 
  • Iteration and refinement: 2-6 weeks 
  • Development handoff: 3-8 weeks 

How much do UI/UX services cost?

The cost of UI/UX design services ranges between $300 and $1,500+ per screen or $25-$200 per hour. The actual price will depend on project type (website design, mobile app design, or product design), feature and design complexity, UX strategy, industry-specific requirements, and the UI/UX design company’s location.

What factors impact the cost of UI/UX design?

Beyond project scope and complexity, factors like design iterations, turnaround time, compatibility requirements, and ongoing maintenance can impact the overall cost of a UI and UX project. Here’s how each item may add to the overall billing: 

  • Extra design revisions: Additional 10%-25% of the initial costs for every round 
  • Paid tools, plugins, and stock assets: 5%-15%  
  • Cross-platform compatibility: 20%-30% 
  • Fast turnaround timelines: 10%-50%  
  • Ongoing optimization and maintenance: 10%-25% 

What is the difference between a UI design agency and a UX design agency?

The difference between a UI design agency and a UX design agency is their focus. A UX designer prioritizes how the product works and feels, such as user flow and wireframes. On the other hand, a UI designer manages how the interface looks and behaves, including the color scheme and typography. 

You can think of a UX as the architect designing the blueprint and the UI as the interior designer, shaping what people see and interact with day-to-day. 

Here are more details on their differences: 

User Interface DesignUser Experience Design
  • User research and user personas 
  • Usability testing and analysis 
  • User journey maps 
  • Information architecture 
  • Sitemaps, wireframes, and prototypes 
  • User flows 
  • Page layout 
  • Interactive elements (e.g., buttons and menus) 
  • Design system (e.g., color scheme and typography) 
  • Mockups 
  • Graphic design, motion design, and illustrations
