      Cross-Platform Review from Mark Gratiot

      In addition to building out a native remote inspection app for iPads, Zco concurrently ported the software to a Xamarin platform for Windows users. Zco has released nine major iterations of the iPad app, each available in the App Store, as well as the initial version of the cross-platform Xamarin build. Their nimble team boasts a wide breadth of skills to match any given situation. Having clear documentation upfront has reduced onboarding time.

      Zco Corporation provided full-stack mobile app development to an educational resource retail organization.

The app has successfully been moved into preproduction and the second phase of development, completely satisfying project stakeholders with the quality of both its designs and functionality.

      Startup Review from J. Michael Webb

      J. Michael Webb from CheckMySpot chose Zco Corporation for app development due to its expertise. Zco adeptly developed a hybrid mobile teledermatology platform and an admin website, demonstrating excellent communication, responsiveness, and innovation. Despite the project's evolving and innovative nature, Zco seamlessly integrated Webb's intent and met all challenges, leaving him with no suggestions for improvement. (Verified via email/call)

FAQs About Web Development Companies

What’s the difference between web development and web design?

Web design focuses on the visual aesthetics and the functional user experience, while web development covers the aspect of building and maintaining the technical foundation that allows designs to function smoothly. 

  • Web design services: layout, colors, fonts, imagery, UI/UX design, accessibility, and responsive design 
  • Web development services: front-end and back-end coding, database, servers, APIs, scalability, security, and performance. 

How do you choose between a custom-built solution and a CMS or low-code platform?

Choose a CMS or low-code platform (e.g., WordPress, Webflow, or Squarespace) when you need to launch your website fast and affordably. These platforms are also ideal for small businesses with lean teams or those that do not have a dedicated development team to maintain a complex site structure.  

Consider a custom-built website if you require unique functionality, tight interactions with internal systems, or performance and scalability beyond off-the-shelf platforms. However, highly tailored websites typically require higher budgets and longer timelines. 

What are the common hidden fees in a web development proposal?

The most common hidden fees in a web development proposal include hosting and infrastructure, compliance and security (e.g., SSL certificates, security audits, and plugins), and ongoing maintenance. Some companies also bill extra for copywriting, graphic design, and marketing (i.e. SEO and analytics setup), as these are typically out of the developer’s scope. 

What red flags should you watch out for when looking for a web development company in the U.S.?

Spotting these red flags early helps protect your time and money:

  • Generic packages and fixed pricing, suggesting templated tactics 
  • You can’t meet the actual team 
  • Extremely low quotes and unrealistic guarantees 
  • Inability to explain their development processes and workflows 

How much do website development companies in the USA charge?

In the U.S., the agencies typically price website development projects between $12,000 and $150,000. Here's what you can expect depending on what you need:  

  • UI/UX design: $2,000-$15,000 per project 
  • Front-end and back-end development: $3,000-$15,000 per project 
  • Database and CMS integration: $2,000-$25,000 per year 
  • eCommerce functionality: $2,000-$25,000 per month 

What non-negotiables should I require from my web development contract?

Your website development contract should define and specify your project's scope, requirements, and what is out of scope. It should also detail timelines, milestones, payment structures, revision policies, exit clauses, confidentiality, and data protection terms.  

Significantly, your contract should clearly state that you own the intellectual property rights, code, design files, accounts, third-party assets, and licenses of the entire project.
