What is software outsourcing? Hiring a third-party provider to handle software development tasks — from full project builds to testing, system integration, or ongoing maintenance — so businesses can access external expertise, speed up time-to-market, and reduce costs without expanding an in-house team.
Why outsource to Vietnam:
- Talented developers — a fast-growing, government-supported tech workforce with continuously improving skills.
- Strong English proficiency — most engineers are college-educated with years of English study, enabling smooth communication.
- Cost-effective rates — $20–$50/hour vs. $80–$150/hour in the US/EU, a 20–40% saving without compromising quality.
- Modern business hubs — concentrated talent in Ho Chi Minh City and Hanoi, both easily reachable via direct international flights.
Top 13 companies covered: InApps Technology, FPT Software, KMS Solutions, Saigon Technology, TMA Solutions, SotaTek, NashTech, Power Gate Software, Enlab, Beetsoft, LinxHQ, ICTS Custom Software, and Adamo Software — each profiled with founding year, specialization, and key achievements.
