WooCommerce Review from Amanda Viviano
We hired Qolos to build our local florist shop's website on WordPress and WooCommerce, and we couldn't be happier with the results. From the start, they took the time to understand our business and created a site that's not only beautiful but easy for our customers to browse and shop.The WooCommerce setup was seamless, our online ordering works exactly the way we needed it to. But what really sets Qolos apart is their ongoing monthly maintenance. We never have to worry about updates, security, or technical issues because they stay on top of everything. Any time we've had a question or a small change request, they've been responsive and professional.As a small local business, it means a lot to work with a team that genuinely cares about keeping our site running smoothly. Qolos has been a true partner, not just a vendor. Highly recommend them to any local business looking for reliable web design and maintenance!

Web Development Review from Sanjay Singh
I kept getting negative reviews about my app for technical glitches, heating issues, functionality, loading time, crashing, and more bugs. So, I reached out to QOLOS after going through 2-3 renowned review platforms. I explained my app issue to the team, and they did tremendous work with their mobile testing solutions. Also, I wanted to build a website for my app. They created a feature-rich and seamless website.

Shopify Review from Sarah Nesheim
Working with QOLOS was the best decision I have made in regards to scaling my business. They are professional, so creative, they communicate every step of the way and their pricing is fair for the highest quality work. The designer of our logo and website did it well and I am so impressed and proud of the final product! the designer listened and knew exactly what I wanted which made the process so simple. Seriously could not recommend QOLOS more!

Amazing and talented people. I’ve worked for both client and agency side and can can say their partnership is amazing. They truly care about ongoing operations and not just ending it at a project level. Highly recommend! Message me if you want specifics.

John Andesilich's Review Sourced from Google
I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

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.
