Elogic Commerce Reviews & Testimonials
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
Head of Marketing at Panem Agency
5.0★
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 Daisy Skot
KitRUM made a variety of development services: conception, coding, and QA, which means almost a full software package for our company. We needed to develop a few tasks, for example, a desktop app for our store, a cloud app for administration and supervision, and a portable app for end customers. However, we had an in-house team, which is not enough for this project. So we had to find a dedicated team that could deliver all we needed. We found KitRUM as a top-notch software development company

Wearables Review from Issac John
A global OTT provider - Discovery+ earlier this year, had a breakthrough launch in a cluttered OTT market like India with a differentiated product targeted at lifelong learners and passionate communities. The team at Robosoft played a significant role in building this multi-platform experience spanning iOS, Android, Web and Fire TVs. Their team comprises an extremely dedicated bunch of folks with a keen problem solving approach and under the stellar leadership of Ravi Teja, Jay Shah, Srinidhi Rao and Pooja Bal, they have been the kind of dependable partners that a lot of brands would be fortunate to have. I wish them and their team the best for their future.

Our experience working with Robosoft has been quite good in terms of product and outcomes. With our CapitaStar@Work app for India business, the end goal was to bring our customers and their employees onto a digital platform. The objective was to integrate our solutions such as visitor, parking, and ticketing system management into a single app. CapitaStar@Work caters to our requirements and surely will make life simpler for our users. I would recommend Robosoft to others because it is a good organization to implement technological interventions in any traditional manufacturing, real estate, or brick-and-mortar industry.

Oversight of our databases have always been a challenge. Finding the skillset to properly administer the systems is both difficult to find and high priced for a mid-sized organization. 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.

Consumer IoT Review from Mason Ferlic
GripFusion is a sports technology startup developing Tactile Intelligence. Our flagship product, the ForceBall, is the first grip-sensing baseball. We approached Atomic Object with the challenge to build a React Native iPad app to connect with the embedded electronics over BLE and visualize sensor data in real time. Atomic stepped up to the plate and hit a home run! They took early R&D code and we're able to successfully navigate IoT challenges, large amounts of sensor data, and seamless UX. The developer team worked closely with our technical staff to incorporate evolving firmware and hardware improvements. The design team did hundreds of hours of user discovery and product feedback to ensure we deliver a cutting-edge experience. Overall, Atomic has the breadth and depth to tackle complex hardware-software systems.

As a freelance Video Producer, I recently wrapped up another fun project with the folks over at Atomic Object, and I've gotta say, it was an experience worth mentioning. Collaborating with their marketing team on a series of authentic and engaging customer-facing and internal videos was nothing short of fantastic. Their seamless planning and logistics during pre-production, coupled with easy going personalities during production, made the process a breeze. Post-production brought our collective vision to life with meticulous story editing and videos that reflect their unique culture and values. Their team's dedication to kindness, empathy, and diversity made this collaboration not just successful, but truly enjoyable.

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%
