What is an IT outsourcing company?

An IT outsourcing company acts as your external technology partner, offering specialized services such as software development, cybersecurity, and technical support. Think of them as an extension of your in-house IT team — managing everything from day-to-day operations to large-scale system integrations.

In today’s era of digital transformation, where the demand for advanced tech expertise often surpasses in-house capabilities, outsourcing provides a practical and strategic solution.

By tapping into global talent pools and cutting-edge technologies, these companies deliver cost-efficient, high-quality IT services on demand, allowing businesses to scale efficiently without the overhead of hiring full-time specialists.

Cost-Effective Solutions

Vietnam offers significant cost advantages for companies looking to outsource their IT needs. Companies can achieve 40-70% cost reduction compared to hiring in-house teams in Western markets. Even within the Asia-Pacific region, Vietnam stands out for its competitive pricing structure.

Vietnam offers competitive infrastructure costs, ranking 12th globally, 6th in Asia, and 1st in Southeast Asia for internet services. On average, internet users in Vietnam spend US$11.27 (or VND260,000) per month on their connection. The typical cost of broadband internet is $12.4 per month, which is much lower than in neighboring countries such as Thailand ($25.9), Indonesia ($32.5), Malaysia ($34.9), and the Philippines ($51.1).

Office leasing in Vietnam is also cost-effective, averaging $15 per square meter per month, about 20% cheaper than in other Asia-Pacific countries. These affordability factors make Vietnam an attractive location for companies looking to set up dedicated development teams or offshore centers.

Skilled and Growing Tech Talent Pool

Partnering with a leading software outsourcing company in Vietnam offers businesses access to a diverse pool of tech talent, ranging from recent graduates to experienced professionals. These candidates are carefully vetted by industry experts and possess strong skills and experience across a range of fields. In addition to their technical abilities, Vietnamese developers are well-regarded for their work ethic, positive “can-do” attitude, and familiarity with global work cultures, making them a perfect fit for international business standards.

This highly skilled workforce is part of Vietnam’s rapidly expanding IT sector, which has gained global recognition. According to the Vietnam IT Market Report 2023 by TopDev, the country is home to approximately 530,000 IT professionals, with more than 57,000 students graduating each year from over 300 universities and training centers, including top institutions like Hanoi University of Science and Technology, Vietnam National University, and FPT University.

Strong Government Support

The Vietnamese government has introduced several supportive policies to promote the growth and development of the IT sector, including:

  • National Digital Transformation Program: Launched in June 2020, this initiative aims to accelerate digital transformation across various sectors and position Vietnam among the top 50 countries in e-government by 2030.
  • National Program for Supporting Innovative Startup Ecosystems (Project 844): This program, which runs until 2025, provides funding, mentorship, and incubation opportunities to foster innovation and support startups.
  • Education Initiatives: The government is modernizing curricula, promoting STEM education, and encouraging collaborations between universities and IT companies for hands-on training and internships.
  • Foreign Investment Incentives: Vietnam offers tax breaks, reduced land lease fees, and streamlined administrative procedures to attract international IT companies.
  • Digital Infrastructure Development: Significant investments are being made in high-speed internet and 5G networks to support the IT industry.
  • Cybersecurity Law (2018): This law ensures a secure online environment by enforcing strict security standards for businesses.

Cultural Compatibility and Communication Skills

Language proficiency plays a critical role in the growth and global integration of Vietnam’s IT outsourcing industry. While Vietnam currently ranks 63rd out of 116 countries in the Education First English Proficiency Index, the country has made significant strides in improving English language skills.

Many IT companies in Vietnam also prioritize language training, collaborating with English centers or offering internal courses to improve their teams’ language capabilities. Furthermore, some professionals learn Japanese and Korean to collaborate with partners from Japan and South Korea, underscoring the strategic importance of these markets. This multilingual ability not only broadens career opportunities but also strengthens Vietnam’s competitive edge in the global IT outsourcing sector.
