    Elogic Commerce Reviews & Testimonials

    • Hanna Dobromyl
      Hanna Dobromyl Technology Partnerships Lead at Akurateco
      5.0

      eCommerce Review from Hanna Dobromyl

      We brought Elogic in as an extension of our engineering team to help Akurateco scale integrations across Shopify Plus, Adobe Commerce, and custom commerce environments for enterprise merchants. Their senior engineers integrated smoothly into our workflows, covering integration development, platform customization, and technical consulting - with communication that stayed transparent, disciplined, and proactive throughout, from status updates to flagging risks early. Elogic's strength showed most in complex B2B commerce - account structures, merchant-specific configurations, and enterprise buying requirements - and in integrating our stack with ERP, CRM, PIM, and other backend systems. When priorities shifted, they adapted without friction, and for an engagement of this scope, the value was clear: their process lowered hiring risk and let us scale delivery without building that capacity in-house. The impact has been measurable: integration delivery accelerated by roughly 3040%, delivery capacity grew by about 50%, and we've been able to support enterprise merchant requirements faster without expanding headcount. This is an ongoing partnership, and Elogic continues to be a reliable technology partner as we scale.

      B2B Review from Anna Korobkyna

      Elogic helped us build and improve the digital experience around our enterprise cybersecurity platform, focusing on customer-facing workflows and a more scalable way for enterprise customers to manage their accounts and services. As our enterprise customer base grew, many processes still required manual involvement from our internal teams, which became difficult to scale. We needed a partner who could understand our business processes and help us build a more efficient and maintainable solution. Elogic supported us with customer portal development, account management workflows, API integrations with our existing systems, backend and frontend development, QA, and ongoing technical improvements. What stood out was their ability to understand the complexity of enterprise requirements and think beyond individual tasks. They focused not only on delivering functionality but also on creating solutions that could support future growth. Communication was clear and proactive throughout the engagement. The team adapted well as priorities evolved and worked closely with us to keep everything aligned. The result has been reduced manual effort in customer workflows, a stronger foundation for scaling enterprise operations, and more time for our internal team to focus on advancing our core security platform. This is an ongoing partnership, and I would recommend Elogic to B2B software companies looking for a technology partner to build scalable customer-facing platforms and complex integrations.

    • Julia Klotsko
      Julia Klotsko Head of Marketing at Panem Agency

      eCommerce Development Review from Julia Klotsko

      We brought Elogic in to build a Shopify store from scratch for one of our clients - a project that required not just a clean storefront but deep integrations with NetSuite for ERP and Brightpearl for order management, alongside our full marketing stack. That combination of storefront and backend complexity is exactly where a lot of agencies fall short.Elogic handled it without missing a beat. The discovery phase was thorough - they mapped every integration touchpoint before writing a line of code, which eliminated the kind of mid-build misalignments that usually cost real time and money to fix. Both workstreams ran in parallel and came together cleanly at launch.The results were tangible: over 120 pre-orders in the first two weeks, 40% above target; order processing errors dropped by roughly 70% after Brightpearl automation replaced manual handling; inventory discrepancies between the storefront and NetSuite went to zero; and paid media ROAS improved by 25% in the first month simply because attribution was finally accurate.Project management was disciplined and transparent throughout - we always knew where things stood, and when requirements shifted mid-build, the team adapted without friction. After launch they stayed actively involved, optimising performance and flagging issues proactively rather than waiting to be asked.For a project of this complexity, Elogic delivered strong value for money. I would recommend them to any agency or business dealing with backend system complexity alongside a storefront build - that's where they genuinely stand out.

      Software Development Review from Mark Griffin

      Due to past experiences, Latent AI is always cautious when hiring external engineering resources for a project. But collaborating with Admios is a breath of fresh air. The agencys account manager is nothing short of professional, attentive, and understanding of client needs. Furthermore, Admios seasoned and self-sufficient engineers fit seamlessly into the Latent AI culture. The team treats and trusts them as one of their own. (Verified via email)

      Off the Grid has had a longstanding developer partnership with Admios. Recently, the client trusted Admios with building a complex React Native POS system and a guest order-ahead app. Given the complexities of the project, Off the Grid wouldn't have chosen any other agency to work with. The Admios' developers did an excellent job, the management was proactive, and the software quality is exceptional. Admios is highly recommended. (Verified via email)

      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.

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.

We reached out to Emergent to find out more about their virtual dba services. Their services sounded to be exactly what we needed. That was over 4 years ago. Since then we found Emergent to be a key partner in helping us in administration of our databases. Our systems are highly efficient, highly available and we feel secure knowing they are under the oversight of some amazingly skilled engineers.

      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.

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
