      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. They worked in Unity to build a cross-platform resource for users to advance through various curricula. 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. The Zco Corporation team is highly creative and collaborative throughout their work.

      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)

      Mobile App Development Review from Mark Joy

      Dima S. responded to one of my job postings on Upwork for creating an audio-related application. He explained the estimated cost of developing such an app, and advised that it would be much more costly than I had anticipated. I was not familiar at all with the costs associated with developing apps, so his explanation was very helpful. He saved me money by going above and beyond to research existing apps that provided similar functionality to the requirements I was seeking. He also found instructions for using native Apple settings for audio that would solve my problem. The settings he found even allowed import of an audiogram that I had gotten at the audiologist for my specifc problem. Though he did not end up developing an app for me, Dima saved me a ton of money by spending his time to research possible existing solutions which I had not found during my own search. I would highly recommend Dima for his level of care for projects and his customers.

      WordPress Website Design Review from Anna Abdulova

      Working with CitrusDev was very comfortable and convenient. CitrusDev developed a website (WordPress) for me with the services I provide to my clients. Since I have a shortage of time, it was important that the team did not need my constant involvement in the process. After discussing all the details, we met a few times to decide on further actions and make corrections. The work format was convenient and clear. And most importantly, it was flexible. The team responded quickly when changes were needed and gave advice for better results. I am happy with our joint project and want to thank CitrusDev for their professionalism and ease of work. Thank you. And I recommend them.

Also in order to get a job here you must have decent technical skills and English language ability. Pros: nice office, friendly staffs that really take care of employees Cons: underpaid salary

      ISBX is a very professional and talented web development company. The overall experience I had with them in the redesign of our website was outstanding. They were extremely creative, provided viable options at all junctures, and delivered on time and on budget. ISBX also provided a very hands-on, and professional team who understood our need for brand engagement and outreach to a new audience with our website refresh. The team also optimized the new site for mobile usage which was very important to us. ISBX successfully executed our complex project efficiently, with excellent communication and attention to detail at every step. I wouldn't hesitate to work with them again.

      I've been a client of ISBX for nearly three years. They are hands down the best development firm I have ever worked with. They are on budget and on time consistently. They are trustworthy, highly communicative, and very versatile. Nothing is in the "too hard box" for them.

Everything you need to know before hiring a software testing company

How can a software testing agency help my business?

A software testing agency can help you maintain good product quality, usability, security, and functionality, which builds customer trust in the long-term.

Research shows that dedicated QA services result in 22% less time spent on remediation and unplanned work.

By reclaiming this lost time, you can reallocate 29% more of your internal resources toward building new features.

The technical advantages are also substantial: having a software testing company on board often results in 2,555 times faster lead times and 200x more frequent deployment.

In addition, having a continuous testing infrastructure in place will allow you to recover from failures 24x faster, which subsequently will yield higher availability for your end users.

From a commercial standpoint, software testing companies prevent the technical friction that causes 67% of customers to abandon an application due to poor performance.

While some customer churn is inevitable due to external factors like user busyness or changing preferences, professional testing will make sure that technical instability is never the cause.

In essence, a software testing agency can provide the validation required to scale your product reliably.

How can I measure return on investment (ROI) in test automation?

In addition to risk mitigation, test automation ROI measures the time saved by automated execution compared to the manual effort required for the same tests. The value can be further determined based on the following:

  • Direct cost reduction: By quantifying the reduction in manual testing hours, organizations see a drastic drop in per-test costs. Automation enables faster release cycles and optimizes resource usage.
  • Risk reduction: Beyond simple bug-hunting, this refers to the business impact of prevented production defects. Higher test coverage automation catches security vulnerabilities and customer experience failures before the software gets launched, subsequently saving the brand from costly remediations and reputational damage.
  • Revenue acceleration: By deploying features faster, companies can realize revenue sooner and improve customer satisfaction through rapid iterations.
  • Team productivity: When considered as an investment, automation testing facilitates better resource allocation, allowing skilled engineers to focus on innovation rather than repetitive tasks, which improves overall team productivity and agility.

What should I consider before hiring software testing firms?

Before hiring software testing firms, discuss their expertise in both manual and automation tools, assess their reputation via references, evaluate culture fit, and determine compatibility with your time zone.

Here are some key considerations:

  1. Technical expertise
    Confirm the firm has experience with your technology stack and specializes in necessary testing types.
  2. Industry experience
    Choose firms with a proven track record in your vertical to make sure you’ll be working with people who understand the relevant regulatory standards and typical user behaviors across the niche.
  3. Communication
    Discuss the frequency of the updates you will receive. Preferably, choose a software testing company that operates within your time zone to avoid delays.
  4. Reputation
    Request case studies and speak directly with past clients to verify their reliability and quality of work.
  5. Security
    Inquire about their data security measures, especially if handling sensitive information, and check for relevant certifications (e.g., ISO, ISTQB).

Frequently Asked Questions About Software Testing Companies

What services do software testing firms provide?

Software testing companies provide different testing services to identify errors, security risks, performance issues, and how the software behaves in real-life situations and across devices. As part of their software testing service, they also check if each feature works as expected, fix bugs, make improvements, and make sure new software development updates don’t break existing functions, so the software quality remains stable. 

Core services include: 

  • Functional testing  
  • Performance testing  
  • Security testing  
  • Usability testing  
  • Regression testing   
  • Automation testing  
  • Accessibility testing    
  • Mobile app testing  
  • API testing  
  • Compatibility testing across devices/browsers  
  • Compliance testing  
  • Testing with artificial intelligence (AI) tools
  • QA audit 

How much do software testing services cost?

Hourly rates for QA testing range from $25 to $200+. The final cost is determined based on the size of the software or application, its complexity, required testing type, tech stack (custom-built and older legacy systems cost more), and niche.  

The rate will also depend on the seniority of the software tester. Across the United States, junior quality assurance (QA) tester may charge $70 to $110 per hour, while the rate for a senior QA mentor and automation engineer can range from $130 to $200 per hour.   

Special software testing services such as QA audit goes from $5,000 to $25,000. 

How can businesses know what type of software testing do they need?

Businesses can determine what type of testing solutions they need based on the potential impact of failures and the likelihood of defects. Namely, if they encounter:  

  • Core functionality issues: Use functional testing to verify features work as expected 
  • Unstable code or new features: Use unit testing for individual components and integration testing for modules working together 
  • Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing features 
  • Performance and load issues: Use performance and load testing to evaluate speed and scalability 
  • Security issues: Security and penetration testing are commonly used across apps handling sensitive user data 
  • Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end users 
  • Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versions 

There is also the option to choose between manual and automated testing.  

Is automated testing more expensive than manual testing?

As an investment, automated testing is pricier than manual testing but offers a lower cost-per-test over time as it can run the same scripts repeatedly, without human intervention. Conversely, manual testing entails lower upfront fee, but its cost grows linearly as the project grows, as every test cycle requires paid hours from QA testers.  

So, for short-term projects or ones with shifting requirements, manual testing is considered a more economical option, whereas for maintenance and regression cycles, automated testing grants better return on investment. 

The main distinction between these methodologies is that manual testing relies on human observation and interaction to identify defects, whereas automated testing uses software scripts to compare outcomes against predicted results.  

Manual testing is best suited for exploratory testing, usability assessments, ad-hoc bug hunting, and minor hotfix verifications where script development would be inefficient. Automated testing, on the other hand, is primarily used for regression testing to make sure the new code does not break existing features. 

How do businesses measure the effectiveness of software testing?

The effectiveness of the software testing is measured via: 

  • Code coverage: The percentage of the code that has been tested 
  • Defect density: The number of defects found per unit of code 
  • Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective tests 
  • Time to detect and fix defects: The time it takes to identify and fix software defects and software bugs 
  • Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase
