Outsource Software Development to Asia: Country-by-Country Guide

Quick Overview: 9 Asian Outsourcing Markets at a Glance

Rates above are all-in monthly costs through Second Talent’s flat $199/month EOR fee, including salary plus statutory employer contributions.

US comparables for senior engineers run $12,000-$18,000 per month base, or $17,000-$25,000 fully loaded with benefits, taxes, and overhead.

Vietnam: The Cost-Output Sweet Spot

Vietnam is the country we place into most often. The 530,000-strong developer population, low statutory employer cost (23.5%), and strong technical universities make it the cleanest cost-to-quality fit.

Hanoi and Ho Chi Minh City together host engineering hubs for Samsung, Intel, Bosch, NAB, and dozens of US-funded startups.

Senior full-stack engineers ship at $3,000-$5,000 per month all-in through our flat $199/mo EOR. That is 50-70% lower than the US loaded cost for an equivalent profile.

Top stacks are Java, Spring Boot, Python, Node.js, React, and increasingly LLM tooling. AI engineering talent is growing 35% year over year per Vietnam Plus IT Workforce Outlook 2025.

Timezone is GMT+7. Vietnamese engineers overlap with US East Coast from 7-10 AM their time. Most teams we place run an async-first model with a one-hour daily sync. English at senior levels is moderate-to-high.

Junior pools are weaker on English but improving fast as international companies expand.

One example: a US fintech client built a 12-engineer Vietnam squad over six months in 2025. The team shipped a full payment platform rebuild while saving $1.6 million versus an equivalent US team.

Indonesia: Mobile and Fintech Strong, Best Cost

Indonesia is the largest internet economy in the region per the Google-Temasek-Bain e-Conomy SEA 2025 report. Local unicorns Gojek, Tokopedia, OVO, and Bukalapak built engineering benches that now spill into the global market.

Senior engineers cost $2,500-$5,500 per month all-in.

Statutory employer cost is the lowest in the region after the Philippines at 11.5%. The 280,000-developer pool is concentrated in Jakarta, Bandung, and Yogyakarta.

Strongest stacks are mobile (Android/Kotlin and iOS/Swift), Java backend, Go, and PHP. Fintech engineering depth is exceptional given the local payments market.

English at senior levels is moderate. Mid-level and junior pools are weaker on English but technical output is strong.

Indonesia works for teams that can afford asynchronous communication and have a senior tech lead bridging the language gap. Hire engineers in Indonesia for stack-specific options.

Singapore: Regional Leads and AI Specialists

Singapore is not a cost-cutting country. Senior engineers run $5,000-$9,000 per month all-in, roughly 50-90% more than Vietnam or the Philippines.

You hire in Singapore when you need a regional team lead who can manage offshore squads, or a senior AI/ML specialist who has worked with state-funded research labs.

The 200,000-developer pool is anchored by Google, Meta, Stripe, ByteDance, and over 80 unicorn engineering offices. Singaporean engineers consistently rank in the top tier on global tech assessments per HackerRank Developer Skills Research.

English is native-tier across all seniorities.

Statutory employer cost is 17%. Timezone GMT+8. Use Singapore for senior cloud architects, AI/ML leads, regional engineering managers, and roles where you need a local interface to the rest of your APAC team.

How to Choose Between These Markets

Three questions narrow the choice fast.

How much does English fluency matter for the role? If the engineer interacts with US customers, attends client demos, or writes technical documentation regularly, the Philippines, Singapore, Malaysia, or Hong Kong are the safest picks.

If the role is heads-down backend or data work, Vietnam, Indonesia, Taiwan, and Thailand are equally strong at lower cost.

What is your timezone overlap requirement? Most low-cost APAC markets sit at GMT+7 or +8. They give US Pacific teams 4-6 hours of overlap if both sides shift slightly. EU teams get 4-7 hours of overlap.

If you need real-time pairing with a US East Coast engineering team, you need engineers willing to work afternoon-to-late-night shifts in their local time, which is doable but reduces the candidate pool.

What stacks are critical? AI/ML and hardware lean Singapore, Taiwan, and China. Fintech leans Hong Kong, Singapore, and Malaysia. Mobile leans Indonesia and Vietnam. .NET leans Philippines.

General full-stack and backend works equally well in Vietnam, Philippines, Indonesia, and Malaysia.

What Outsourcing to Asia Costs Over a 12-Month Engagement

Cost modeling matters before you commit. A 5-engineer team in Vietnam at $4,000 per engineer per month costs $240,000 over 12 months. The same team in San Francisco runs $1.1 million loaded.

The savings differential of $860,000 per year is what funds your runway extension or product expansion.

Singapore changes the math. Five Singapore engineers at $7,500 each run $450,000 over 12 months. Still 60% cheaper than US, but the value is in the regional management capability rather than raw cost cut.

Most successful Asia engagements we see mix one Singapore lead with three to six engineers in Vietnam or the Philippines.

Statutory employer contributions are real numbers. Hong Kong’s 6.5% rate adds $260 per month to a $4,000 senior engineer. China’s 31% rate adds $1,240 to the same engineer.

The country selection has a measurable downstream impact on total cost. Run your numbers through the offshore hiring cost calculator for your specific team configuration.

The Bottom Line on Outsourcing to Asia

Asia outsourcing is no longer a cost-only decision. The talent pool, AI tooling adoption, and remote engineering maturity have all caught up to the point where output gaps are single-digit percentages on most stacks.

The right country depends on your role profile, your timezone, and the level of English-language client interaction the engineer needs to handle.

Vietnam, the Philippines, and Indonesia anchor the low-cost tier with 70-78% savings versus US loaded cost.

Singapore, Hong Kong, Taiwan, and China sit higher on the price curve but unlock specialty skills (AI/ML, fintech, hardware, regional management) that the lower-cost markets cannot reliably deliver yet.

Malaysia and Thailand split the middle with mid-tier cost and strong English at senior levels.

Pick by role fit first. Optimize cost within the matching countries. Use an EOR for compliance from day one. Run the engineer through the same review and ownership process as your onshore team.

Those four moves separate the engagements that work from the ones that don’t.
