Top 10 reputable software outsourcing companies in Vietnam

Many digital transformation projects fail to meet expectations not because of a lack of technology, but because businesses choose the wrong software outsourcing partner. When solutions do not align with operational needs, systems become difficult to use, unstable, and generate additional costs after handover. The article below summarizes market trends and introduces reputable software outsourcing companies in Vietnam based on practical implementation criteria.

Overview of the software outsourcing market in Vietnam

Why are businesses increasingly outsourcing software development?

Businesses choose external software outsourcing companies because of the following clear benefits:

• Cost savings: Reduce recruitment costs, salaries, benefits, and the expenses of maintaining a permanent in-house IT team.
• Access to skilled talent on demand: Add the exact roles needed and scale resources up or down according to each project phase.
• Faster implementation: Leverage established processes and available teams to shorten the time from idea to a live, working product.
• Reduced internal technical management burden: Lessen the pressure of managing a development team and focus more on core business activities.
• Adoption of new technologies without large investments: Easily access modern technologies and implementation experience, especially in a competitive market with a shortage of IT talent.

Common software outsourcing models today

Models by delivery location

• Onshore outsourcing: Teams operate within the same country, making face-to-face collaboration easier and ensuring alignment in language and operational context.
• Nearshore outsourcing: Teams are located in nearby countries with similar time zones and distance, helping balance cost efficiency and collaboration capability.
• Offshore outsourcing: Teams are based in more distant countries, often optimizing costs but requiring clear governance and communication mechanisms to limit requirement misalignment between the business and the software outsourcing company.

Models by project development approach

• Waterfall: Projects follow sequential stages from requirements to design, development, testing, and handover, typically used when requirements are stable and changes are minimal.
• Agile/Scrum: Projects are divided into short iterations with regular reviews to incorporate feedback, effective when incremental delivery and continuous adjustment are needed.
• V-Model: Each development phase has a corresponding testing phase, suitable for projects that prioritize testing and strict acceptance criteria.
• Spiral: Projects iterate through cycles of planning, prototyping, risk assessment, and expansion, worth considering when technical risks are high or requirements cannot be finalized at the outset and require a software outsourcing company to collaboratively refine them over time.
