Applications Review from Denis Khorolsky
We worked with DevIT on a Shopify app for one of our ecommerce clients. The app handled product personalization, pricing rules, and personalized order data, while our team worked on the main Shopify platform and customer experience. The teams worked well together, and the client was able to launch the new feature without changing the existing store.

Small Businesses Website Development Review from Oleksandr Romanov
We worked together with DevIT Group on a financial operations platform for a shared client. Our team focused more on the core product and Python backend, while DevIT handled the infrastructure side using Node.js services built with NestJS and Fastify.
They worked on integrations, payment flows, internal APIs, notifications, and async processing between different services. A lot of the project depended on things working reliably in the background, and their part stayed stable even as new integrations were added later.
The collaboration felt pretty easy overall. Most discussions were direct and technical, without too much unnecessary process around them.

Small Businesses Website Development Review from Viktoriia Rekonvald
We worked alongside DevIT Group on a fintech platform for a shared client. Our team handled the blockchain layer, while DevIT was responsible for the web application built on a MERN stack.
They took care of the full application layer, including the React frontend and Node.js backend. Their part covered wallet connection flows, transaction tracking, and syncing on-chain data with the app. The way they handled API logic and off-chain data storage kept the system predictable even when blockchain confirmations were delayed.

Chop Dawg helped us turn our gifting app concept into a working prototype, handling wireframes, UI design, coding, data storage, and automation from scratch. Their team has been transparent, proactive, and highly responsive throughout the process. They provide clear schedules, flag issues early, and keep us informed at every stage. We’ve been very happy with the prototype so far and are excited to move into full iOS and Android development.

Chop Dawg took our iOS app from concept to launch, handling design, development, AWS, and App Store requirements. Their team was responsive, practical, and highly supportive throughout the process. They also stayed involved after launch with updates and fixes, and even helped promote the app through their network. Their support contributed to strong early growth and helped position the company for a later acquisition.

Chop Dawg supported us with UX/UI design for a new fintech web application. They took the time to understand our users, product requirements, features, and overall vision before moving into design. Over a 6 to 7 week engagement, their team shared regular Figma reviews, incorporated feedback quickly, and stayed highly responsive. They finished ahead of schedule with no budget issues, and the internal response to the final designs has been very positive. Their attention to detail, professionalism, and ability to keep the process organized made them very easy to work with.

Web Development Review from Kelly Anne Kah
Digital Aptech Pvt. Ltd. successfully developed and designed a comprehensive real estate platform, incorporating post-launch performance metrics. Their in-depth research of industry competitors laid the foundation for a tailored design that met our unique needs. During the design phase, they effectively balanced a variety of requirements to serve both our existing and prospective customers.
The project began with an analysis of competitor websites, examining their organizational structures and adapting them to align with our sales and operational processes. The result was a site inspired by leading industry platforms, featuring a home feed where users could explore properties of interest. Additionally, the platform was enhanced with features that allowed current customers to track their properties throughout the sales process. Digital Aptech Pvt. Ltd. also integrated links to our property management portals for seamless navigation.
Throughout the project, we collaborated extensively using Figma and Salesforce. They implemented a Multiple Listing Service (MLS) data feed, a critical real estate data solution, and extracted valuable insights from the website to support our sales team. By integrating this data feed and other innovative features, Digital Aptech Pvt. Ltd. significantly increased visitor traffic and conversions on our platform.
Their team demonstrated exceptional responsiveness and provided a combination of technical expertise and excellent customer service. Digital Aptech Pvt. Ltd. proved to be a communicative and reliable partner, delivering a robust solution that met and exceeded our expectations.

We started off with some discovery sessions and a beta demo, then went through a few rounds of tweaks where they adjusted both how it worked and how it looked based on what we asked for. The whole build went pretty smooth. Gotta say, Mikhail, the PM, was great to deal with. Super easy to talk to and somehow turned what I wanted into clear technical stuff without me having to overexplain.

Software Development Review from Darshan Chordia
We worked with Techstack to create a digital platform that would simplify how we manage projects, materials, and client interactions. The idea was to make our process more transparent and efficient while keeping the quality and uniqueness of our products at the center.
From the beginning, Techstacks team understood our needs clearly. They built a stable, modern system that allowed us to manage workflows, track materials, and visualize designs in real time. Everything worked smoothly across devices, and the new platform handled large amounts of visual data without any performance issues.
Communication was easy and professional throughout the project. The team stayed responsive, respected deadlines, and quickly adapted to feedback. We appreciated how they approached the project with both technical precision and creative understanding, making sure the solution supported our way of working.
The result made a big difference for us. We now have a reliable, easy-to-use platform that saves time, improves coordination, and helps us deliver better experiences for our clients. Working with Techstack company felt effortless - they were consistent, thoughtful, and committed to getting every detail right.

Software Development Review from Sidharth Dugar
We worked with Techstack to develop a digital platform that could support the financial and operational needs of our growing client base. Our vision was to create an integrated web solution that would bring together financial management, client communication, and digital infrastructure into one cohesive system. The goal was to give small and medium-sized businesses the same level of data visibility and workflow efficiency that large enterprises enjoy but through a user-friendly, scalable product.
Techstack company quickly understood what we were trying to achieve. They built a modern web application architecture that unified financial analytics, project tracking, and CRM capabilities while ensuring top performance and security. Their team handled everything from backend development to UX optimization.
What stood out most was how seamlessly Techstacks team balanced precision with flexibility. We had tight deadlines and evolving priorities, yet they consistently delivered on time without compromising quality. Communication was clear and proactive, we always felt aligned, even as the project evolved.
The result was a platform that allowed us to operate more efficiently and deliver a better experience to our clients. It centralized our data, reduced manual processes, and helped us scale faster without adding unnecessary complexity. Techstack brought strong technical expertise and a genuine sense of ownership to the project, turning a challenging concept into a powerful business tool that continues to grow with us.

Web Development Review from Sri Sharma
When we brought Techstack on board, our analytics subsystem was at a breaking point. Performance issues, data inconsistencies, and outdated architecture were slowing us down and creating friction for both our internal teams and end users. Given the scale of our platform: millions of customer interactions generating terabytes of data daily we needed a partner who could not only fix the flaws but also future-proof the entire system.
Techstack company took on the challenge with impressive precision. Their team started with a deep audit that revealed critical weaknesses in our existing infrastructure. From there, they restructured the backend, optimized performance, and built a reliable synchronization flow between our internal tools and third-party CRMs. Techstack introduced a new architecture powered by Amazon Redshift and an asynchronous analytics engine, which dramatically reduced data retrieval times and improved responsiveness across the board.
What we appreciated most was how seamlessly they integrated into our process. They communicated clearly, delivered consistently, and made sure every change was fully tested and stable before rollout. The results were: system reliability improved, performance bottlenecks disappeared, and we could finally handle large-scale data processing without worrying about stability. Techstack company combined strong engineering skills with a genuine commitment to understanding our goals. They helped us rebuild confidence in our platforms ability to scale and perform at its best.

Mobile App Development Review from Chris Caputo, PMP
After looking at multiple vendors to build an app to provide information on municipalities we selected Quartus. The scope included the development of the app (including designs) and integration to a service that our development team created. Quartus was successful. They delivered in a timely, cost-efficient manner and were easy to work with. When we decided to have a second app created, we did not look elsewhere and stayed with Quartus. This app involved the development of a calculator to calculate and email title insurance premiums. Like our first app, Quartus had to develop the designs (they were able to leverage a portion of the work from our first app) and integrate to a different service that our development team created. Once again, Quartus delivered. These apps were for Android and iOS. They are a good partner.

We spoke to a few different companies as we set out to find someone to create a website/database application to augment our desktop software. We chose The Demski Group in part because we found them very easy to talk to in our interview. That first impression stuck as we have a great relationship with them now. We are currently planning to farm out another project and are not even considering looking for anyone else to take it on.

What services does a software testing company provide for your business in the United States?
They provide a comprehensive range of services designed to validate and improve software quality through systematic evaluation and advanced tooling.
Core testing services include:
Quality assurance and testing strategy: Audits software and defines testing scope, priorities, coverage, approach, and reporting.
Functional testing: Verifies that software features work according to specified business and functional requirements.
Regression testing: Detects unintended issues introduced by system changes and releases.
Performance and load testing: Measures the application’s reliability and responsiveness during peak usage.
Security testing: Identifies and resolves security vulnerabilities and tests against compliance and governance requirements.
Usability testing: Assesses user experience, interface intuitiveness, and overall accessibility of the solution.
Integration and API testing: Validates how different system components and third-party services work together.
In addition to these services, software testing companies implement a mix of manual (often for exploratory and user experience-focused scenarios) and automated (repeatable checks throughout the development cycle for speed and consistency) testing models.
How much does software testing cost?
Software testing costs about 15%-25% of the development costs or 23% of the IT budget. In terms of hourly rates, US software testing companies charge an average of $100-$250 per hour, with more complex systems or specialized tests going beyond $300/hour.
The final rate will depend on solution complexity, testing coverage, quality requirements, project timeline, and current technical debt.
Here’s how much software testing costs as a percentage of the software development budget:
Critical systems and highly regulated industries: 40%-50%
Enterprise applications: 25%-35%
Consumer-facing applications: 15%-25%
Mobile applications: 20%-30%
In practice, basic one-time testing projects, such as a website penetration test, cost approximately $5,000-$10,000.
On the other hand, continuously evolving software solutions that require regular comprehensive testing can fetch between $20,000 and $70,000+ per month.
Are there any additional costs to consider when working with US software testing agencies?
Beyond project scope, complexity, and timeline, these are additional costs to consider when working with software testing agencies in the USA:
Tooling and platform fees: Software license or subscription fees for device farms, performance testing platforms, and security scanning tools may be billed separately from the company’s overall rates.
Device/browser lab coverage: For tests that require broad compatibility coverage, costs can increase based on access to real devices, operating system versions, and browsers.
Scope growth: New testing requirements, additional integrations, new platforms (mobile/web), or expanding acceptance criteria often require a change order.
Additional test cycles: Extra rounds of re-testing and regression tests beyond what’s defined in the service level agreement (SLA) incur additional costs.
Defect remediation effort: Fixing defects is often outside the testing scope and is billed as an additional engineering or development fee.
Compliance and security deliverables: If you require additional formal evidence (e.g., audit artefacts and traceability) or expanded security testing, expect incremental charges.
How long does software testing usually take?
On average, software testing takes around 20%-40% of the total software development time. However, the final timeline will depend on infrastructure complexity, test scope and methodology, and quality requirements.
Here’s an approximate software testing timeframe based on the typical software project schedules:
Full Release Schedule
Software Testing Timeframe
Small software builds (e.g., Landing platforms)
12-24 weeks
2-4 weeks
Mid-sized builds (e.g., Fully customized mobile apps)
16-40 weeks
3-4 months
Large builds (e.g., Multi-module platforms)
36-144 weeks
6-12 months
Notably, software testing is often integrated into the software development lifecycle (SDLC). As such, it’s common to see QA and testing done in 1-2-week sprints rather than a separate stage altogether.
What industries do US software testing firms typically work with?
US software testing providers work with a wide range of industries, as all digital solutions need to be tested in some capacity. However, these are the sectors that quality assurance (QA) and testing experts work in based on the State of Testing Report 2025:
Tech: 35.2%
Finance and insurance: 16.9%
Others: 12.7%
Healthcare: 10.9%
Business and information: 4.5%
Retail: 4.1%
Marketing: 3.7%
Transportation: 3%
Government: 3%
Gaming: 2.6%
Education: 1.9%
