Web Development Review from Chris Bailey
I engaged their web-development team to rebuild and modernize our company's manufacturing website, and the experience has been exceptional. From the outset, communication was clear and responsive: they took time to understand our industry-specific compliance needs and translated them into a site structure that is clean, secure, and easy to navigate. Delivery was on schedule, and the final result exceeded expectations pages load quickly, the design feels professional and trustworthy, and the content layout supports clarity for both clients and regulators.In addition, the team proactively suggested helpful enhancements: mobile optimization, streamlined navigation, and improved documentation pages all of which have already resulted in noticeably increased user engagement and lower bounce rates. They handled feedback promptly and implemented corrections without fuss, making the collaboration smooth and efficient.Overall, this project added significant value to our online presence, giving us a polished, modern website that accurately reflects our manufacturing standards and commitment to quality. I would gladly work with them again and recommend their services to anyone seeking reliable web development for regulated-industry clients.

Staff Augmentation Review from Sergey Novik
Were developing an internal image processing tool for our design team and needed two machine learning engineers, since our core developers were busy with other client projects. We required extra hands familiar with Python and computer vision, so after a developers market review, we hired them from SumatoSoft.The SumatoSoft developers joined our team and were able to swiftly adapt to our workflows, which resulted in them delivering the working models well before our hard deadline.Communication was straightforward throughout the engagement. We had video calls and exchanged brief text updates on a weekly basis. The delivered code is clean, and pull requests are well-documented.I appreciate that they pushed back on a few of our initial architecture ideas. They challenged our original approach and proposed a better method for handling the model weights. We plan to bring them back for the next phase of development.

Web Development Review from Domien Van Eynde
SumatoSoft is the firm to work with if you want to keep up to high standards. The professional workflows they stick to result in exceptional quality. Important, they help you think with the business logic of your application and they don’t blindly follow what you are saying. Which is super important. Overall, great skills, good communication, and happy with the results so far.

eCommerce Development Review from Alexander McCaig
The system has produced a significant competitive advantage in the industry thanks to SumatoSoft’s well-thought opinions. They shouldered the burden of constantly updating a project management tool with a high level of detail and were committed to producing the best possible solution.

Conversational AI Review from Austra Kausiniece
Oxagile took the time to really understand how our real estate agency works before building the AI calling agent. The custom solution was designed around actual sales process, and it now handles the first call with a lead. It speaks Latvian, asks the right questions, qualifies leads, arranges a callback, and gives human agents a qualified lead with the transcript attached. We've already seen a clear business impact, with at least three solid deals a month coming from conversations initiated by the Austra Nova AI call center. Leads are contacted and qualified much faster, and the cost per lead has also come down. What we appreciated most was how closely they worked with AVER's team throughout the project. Our sales people reviewed call recordings, shared their feedback, and Oxagile used it to continuously improve the scripts and the solution. It felt much more like working with internal team members than with an external technology provider. Just as importantly, they managed to deliver a highly customized solution much faster than we expected. Their use of Anthropic's Claude throughout the development process helped move quickly. For a company of our size, we didn't expect to get this level of customization, flexibility, and speed without a large investment, but Oxagile made it possible.

Software Development Review from Ali Krynitsky
We first met the Cybergizer team at a conference where they talked about their experience with AI in healthcare. Around that time, we were actually looking for a solution to turn doctor-patient conversations into written documents using an LLM speech-to-text model. The idea was to generate a summary that could later be shared with the patients family.The tricky part was getting the model to handle all the complex medical terms doctors use and making sure the output was accurate and reliable.Cybergizer jumped in and helped us get everything up and running super fast. Thanks to their support, we were able to deliver the solution to our client in record time and basically save the whole project (and the client's business too).They were incredibly flexible with processes and approaches, which really mattered since the whole situation was pretty unconventional with tight deadlines and lots of legacy issues.Were still working with Cybergizer on other parts of our business and can honestly say theyre a great partner to have on your side.

Matt Taylor's Review Sourced from Google
Experience working with HQ has been great, treating us more as a partner rather than a client. They stay on top of app trends and help us to create great UI/UX experiences. They are big enough to deliver what we need with quick turnaround, yet small and nimble enough to be flexible with our demands. Definitely recommend!

Software Maintenance Company Hiring Guide
What is a software maintenance company?
A software maintenance company is a specialized IT company that optimizes software products to ensure they remain agile, functional, and aligned with the latest technological advancements. Its core focus is maintaining software quality by eliminating bugs and glitches, improving user experience, and supporting product growth and scalability.
As part of its software maintenance and support services, this agency also helps businesses resolve some of the following challenges:
- Crashing and poor-performing software
- Low user engagement and high user churn rate
- Inability to integrate with operating and data systems, API versions, and communication protocols
- Incompatibility with newer devices and their operating systems
- Reliance on legacy code, which can incur higher maintenance costs and hinder integration with modern technologies
- Inability to comply with the latest international regulations
- Limited in-house expertise and resources for software development, testing and maintenance
- Frequent cybersecurity incidents across existing software
Valued at $209 billion in 2023, the software maintenance service market is predicted to reach $807 billion by 2031, with a compound annual growth rate (CAGR) of 18.45% from 2024 to 2031. The market is projected to grow due to the increasing need for operational efficiency and evolving customer demand for digital solutions.
Success story
For a more concrete understanding of what software maintenance companies can do for businesses, we selected this case study from ELEKS:
- Challenge: Network solutions provider Medusabusiness partnered with ELEKS to re-engineer and update its flagship product, Medusa, that was approaching the end of its technological and economic lifecycle.
- Solution: ELEKS reworked Medusa's architecture on the cloud and updated its traffic routing. Then, it produced a minimum viable product (MVP), performed quality assurance, and implemented self-service functions. ELEKS also provided continuous support and maintenance, integrating off-the-shelf solutions to support the client’s evolving needs.
- Results: Through its specialized expertise in network routing and software engineering, ELEKS ensured zero issues for 90% of Medusa’s upgraded features, which saved Medusabusiness 40% on operational costs and 20% on support efforts. Moreover, the enhanced product led to a 10% customer growth.
What do software maintenance companies do?
Software maintenance companies modify and update websites, applications, and other systems to resolve issues that have manifested post-launch and improve the product’s overall performance. This allows the solution to stay effective, competitive, secure, and adaptive to evolving technologies and industry standards.
Key software maintenance services include:
- Software audit
Analyzing the software to assess overall quality, test for issues, and measure it against a business’ envisioned objectives and the latest standards and regulations - Hosting and infrastructure maintenance
Managing servers, databases, and other software infrastructure components to ensure undisrupted operation and scalability - Bug/Corrective software maintenance
Repairing minor software defects that impact the app’s overall functionalities, like bugs, glitches, errors, and faults - Preventative software maintenance
Taking premeditated measures such as documentation updates, code optimization, and data backup to safeguard against potential issues and vulnerabilities - Perfective software maintenance
Amplifying functionality to fulfill the users’ needs by adding new capabilities, implementing user feedback, and removing outdated and ineffective features - Adaptive software maintenance
Implementing software changes to adhere to new business policies, changing regulatory requirements, or software and hardware updates - Backup and disaster recovery
Backing up software data and establishing processes to quickly restore operations in case of a disaster or emergency - Quality assurance
Conducting rigorous tests to identify and resolve functionality defects and ensure the software aligns with the latest practices, regulations, and quality standards - Product migration
Transitioning an existing product to a new platform or technology while maintaining data integrity and functionality
Success story
To showcase software maintenance services in action, we have selected this case study from iQuasar:
- Challenge: A commercial process improvement company engaged iQuasar to migrate and update its existing application, originally built with an outdated version of VC++ and C#. The application faced several critical issues impeding its scalability and maintenance, including fragmented and overly complex code, inefficient workflows, incomplete documentation, incompatible external library dependencies, outdated UI/UX, and outdated technologies and plugins.
- Solution: iQuasar upgraded VC++ and C# to the latest version, including the attached components. It also consolidated and organized the codebase, enhanced code readability, optimized the code image, implemented a stable and adaptable workflow by decoupling select modules, and audited and upgraded the external library. Moreover, iQuasar focused on producing a modern and user-friendly UI/UX design and provided comprehensive project documentation that followed the industry’s standardization practices.
- Results: The collaboration with iQuasar led to a more robust, stable, efficient, and future-ready application with increased performance longevity and user satisfaction.
What is the difference between software maintenance and support?
The difference between software maintenance and support lies primarily in their scope of work. Software maintenance involves ongoing improvements and updates throughout the entirety of the software development lifecycle to ensure long-term product value in the long term, including bug fixes, performance optimization, and feature enhancement. In contrast, software support addresses immediate user issues, provides quick fixes and troubleshooting, and helps end-users effectively use the product.
Other key distinctions include:
| Software maintenance | Software support |
| Assists companies supplying the software | Provides assistance to end-users |
| Resolves issues that impact software’s function, performance, and other aspects | Fixes short-term functional issues that impact user experience |
| Services include updating code and features, optimizing performance, fixing bugs, implementing security and preventive measures, and ensuring environmental adaptation | Services include troubleshooting, user training, remote assistance, and onsite support |
How much do software maintenance services cost?
Software maintenance services cost between $5,000 and $50,000 per month. Enterprise software maintenance fees can reach up to 70-90% of the total cost of ownership, while fees for mobile and web app maintenance amount to 15-20% of the original development costs.
The range of these costs can vary significantly, depending on several factors:
- Type of maintenance
- Age of software system
- System complexity
- Hardware stability
- Number of new features, functionalities, and integrations
- Number of internal and external users
- State of documentation
- Length of agreement
- Agency location and expertise
Why should I hire a software maintenance service?
You should hire a software maintenance service to resolve software issues, scale your software product, and ensure that it remains valuable to your target users, ultimately, contributing to your business continuity and profitability. Outsourcing such a service allows you and your team to focus on core business activities while you rely on an expert team to optimize your software.
Software maintenance companies can also help you:
- Improve product reliability by fixing arising problems, including bugs, slow-loading systems, and poor-performing features
- Improve software efficiency by optimizing codes and retiring outdated functions
- Elevate user experience by updating or adding new capabilities that meet users’ needs
- Increase cost-efficiency, as software maintenance companies can provide you access to professional tools, software, and technology
- Extend product lifespan by keeping it up to date with the latest hardware and software systems
- Improve user adoption through application programming interface (API) integrations and software interoperability
- Navigate the security and privacy regulations of different regions
- Migrate legacy software without losing valuable data and key software functions
- Safeguard against sophisticated cyber-attacks
Success story
To further emphasize the befits of hiring a software maintenance company, we handpicked a case study from Origina:
- Challenge: Trustmark National Bank (TNB) faced a complex challenge in moving away from IBM after an unfavorable three-year agreement. With IBM proposing significant fee increases for renewed support, the bank sought to avoid a new multiyear commitment while maintaining essential support for its software. To manage this transition, Trustmark required a skilled maintenance partner to sustain its current software without extending reliance on IBM.
- Solution: TNB entrusted Origina to manage and support 85% of its systems. The agency maintained all versions of TNB’s IBM software, provided expert guidance on software licensing, and helped TNB migrate away from IBM’s support while ensuring compliance with financial industry regulations. It also produced custom software for products that TNB decided to discontinue in the long term and implemented robust cybersecurity to all systems.
- Results: TNB secured over $5.5 million in savings, gained control over its software lifecycle, and increased operational efficiency and security.
