What Is Custom Software Development in Hanoi?
Custom software development in Hanoi is the process of designing and building software tailored to a business or individual’s specific needs. Unlike off-the-shelf software with fixed features, customized software is tailored to a company’s workflows, objectives, and unique requirements, ensuring maximum compatibility and efficiency.
Benefits of Custom Software Development
In the digital era, every business has its own operational model and strategic goals. Using generic software often fails to meet all practical needs. Therefore, custom-built software becomes the optimal solution, offering flexibility, performance, and scalability.
Tailored to Unique Business Needs
Each business operates differently. Custom software is developed by carefully analyzing real user needs, ensuring the product includes all necessary functions, an intuitive interface. It features that fit business operations, enhancing productivity and saving time.
Advanced and Scalable Features
Unlike template-based software with limited functionality, custom-built systems can integrate specialized features designed for real-world business processes. This enables automation, seamless data synchronization, and better control across departments.
Enhanced Security
Data security is crucial in today’s competitive environment. Custom software solutions incorporate robust security measures to prevent unauthorized access, information leaks, and data theft – protecting customer trust and business reputation.
Easy Maintenance and Upgrades
Custom-developed software comes with transparent source code, making maintenance, updates, and feature expansion efficient and straightforward. With a flexible architecture, businesses can adapt quickly to market and technological changes while minimizing downtime.

Top 5 Custom Software Development Projects Most Implemented in Hanoi
Corporate Website Design Software
During brand building and development, a website is almost always the first platform every business needs. Therefore, custom website design is one of the most in-demand software development services in Hanoi. A professional website not only serves as a channel to introduce the business, products, and services but also reflects its vision, core values, and growth direction. Depending on the company’s scale and goals, websites can be developed using various programming languages and frameworks such as WordPress, Laravel, or ReactJS.
Among them, WordPress dominates the Vietnamese market, with approximately 60–70% of businesses using it due to its affordability and quick deployment. However, it has certain limitations in speed, security, and deep customization. Hence, companies should consult reputable custom software development providers, such as TopOnTech, to obtain suitable, practical solutions.
Business Apps and Sales Applications
Alongside websites, mobile applications have become indispensable tools for modern businesses, especially in the retail, service, and e-commerce sectors. Having a dedicated mobile app helps businesses easily connect with customers, improve user experience, and enhance personalized customer care. Many companies now choose to develop both apps and websites simultaneously to ensure brand consistency, feature alignment, and seamless operational flow.
Internal Task Management Software
After the COVID-19 pandemic, the rise of remote and hybrid working models has significantly increased demand for task management software. Although popular tools such as Trello, Jira, or Base.vn exists, not all businesses find them suitable in terms of functionality, security, or scalability. As a result, many companies in Hanoi are turning to custom task management software development to build systems tailored to their specific internal needs, ensuring seamless integration with their existing platforms.
AI-Integrated Software – ChatGPT Solutions
Integrating AI technology—particularly ChatGPT—into enterprise software has become a strong trend in recent years. Many Hanoi-based businesses have requested systems integrated with ChatGPT via API to support various operations, such as customer support chatbots, intelligent task management, data analysis, and automated content generation. Thanks to its natural language processing and continuous learning capabilities, ChatGPT-integrated software not only helps reduce manpower but also greatly enhances efficiency and user experience.
Sales Management Software
This is one of the most popular and frequently requested types of software, especially among retail companies, store chains, and distribution enterprises. An effective sales management system enables businesses to closely monitor their operations, from orders and inventory to finances and sales reporting. In the booming e-commerce landscape, investing in a dedicated sales management system helps businesses gain greater operational control, optimize costs, and minimize data processing errors.

TOT’s Software Development Process in Hanoi
At TOT, every software product is built through a systematic, rigorous 8-step process that adheres to international standards. This not only ensures high-quality output but also allows clients to monitor and control project progress with complete transparency.
Business Process Survey and Understanding
TOT works directly with relevant departments to survey and capture the entire current operational process of the business. Through interviews, we identify how the organization operates in reality, analyze and clarify “pain points” – the bottlenecks and challenges that currently exist – to fully understand the client’s needs.
The processes are visually represented using BPMN diagrams, flowcharts, or mind maps, helping both the enterprise and the technical team clearly see the problems.
This is a foundational step, especially for businesses that have not yet standardized their processes or have never implemented a software system before.
Requirements Gathering & Implementation Proposal
Based on the requirements and objectives collected, TOT proposes a detailed software development plan that includes the system architecture, core features, technologies to be used, and security orientation.
All proposals are presented transparently, aligned with real-world needs, and easy to implement.
Interface Design and System Programming
The software interface is designed to optimize user experience (UI/UX) while still reflecting the brand’s identity. TOT uses professional tools such as Figma and Adobe XD to create prototypes before moving into official coding using modern technologies like Node.js, PHP, and Python.
Software Development (Agile Methodology)
The development process at TOT follows the Agile model, allowing flexibility, speed, and adaptability to change. Each sprint is reported periodically so that clients can clearly track progress and provide timely feedback.
Quality Testing
Once developed, the software undergoes strict multi-layer testing, including:
- Functional testing
- Performance testing
- Security testing
- User experience testing
TOT ensures that the final product meets the highest quality standards before moving on to the trial phase.
Training and Handover
TOT conducts training and system handover sessions to ensure that the business can confidently operate the system effectively.
We provide a complete set of instructional documents throughout the implementation process, helping businesses easily manage, train internally, and maintain the system in the long run.
In addition, TOT collaborates with the client to organize User Acceptance Testing (UAT) sessions to ensure the software meets real-world needs and expectations.
This helps the business be more proactive during operations and reduces dependency on the development team.
Alpha and Beta Testing
During the alpha testing phase, TOT performs internal testing to detect early errors before moving on to beta testing, where clients experience the product in real conditions. TOT applies CI/CD (Continuous Integration/Continuous Deployment) to ensure quick updates and smooth operation from day one.
Maintenance, Upgrades, and Continuous Improvement
TOT is committed to supporting clients even after official deployment.
Our maintenance service includes:
- Regular updates
- Bug fixing
- New feature enhancements
- Continuous technical support
These services ensure that the software always runs stably, securely, and efficiently.m TOT also evaluates the software’s real-world performance using key indicators such as processing speed, system uptime, and user engagement rates. At the same time, we conduct user interviews and collect feedback from relevant departments to further optimize performance and identify future improvement opportunities.
