Top 10 Offshore Software Development Companies in Vietnam (2026)

Vietnam's best offshore software development companies in 2026 include MONA, FPT Software, TMA Solutions, NashTech, KMS Technology, Saigon Technology, Savvycom, Orient Software, Rikkeisoft, and Sun*. They range from a 30,000-person global corporation to focused 300–700-engineer firms. This guide compares team size, certifications, and specializations so you can shortlist the right fit.

Full disclosure before anything else: this list is published by MONA, and we've put ourselves at #1. We're not pretending to be a neutral directory, but every claim about every company below is sourced from public information (company websites, Clutch, LinkedIn), and we've listed nine genuinely strong competitors, because a shortlist that only works when you hide the alternatives isn't worth publishing.

Quick Comparison: Vietnam's Top Offshore Software Companies

How We Chose These Companies (Methodology)

We evaluated Vietnamese offshore vendors against five criteria, using only publicly verifiable information:

1. Engineering depth. In-house employed engineers, not assembled freelancers. Headcounts below come from each company's own website, LinkedIn, or Clutch; where sources disagree, we say so.
2. Track record. Years operating and evidence of long-term client relationships (named clients, review volume).
3. Process maturity. Certifications like CMMI and ISO 27001, cited only where publicly confirmed. Where a certification couldn't be verified, we don't claim it.
4. Client feedback. Clutch ratings, always with review counts, because a 5.0 from 2 reviews means less than a 4.8 from 20.
5. Clear specialization. What each firm is actually best at, so you can match vendor to project instead of picking by rate card alone.

Every company on this list is real, operating, and independently checkable. No pay-to-play placements.

1. MONA — Best for SMBs and Mid-Market Companies

Yes, this is us. Here's why we put ourselves first. MONA is a Ho Chi Minh City–based development company with 200+ staff, employed, not a freelancer network, delivering 14,000+ projects since 2016. That delivery volume is unusual in this list: where most offshore vendors run a handful of large enterprise accounts, MONA's model is built for the businesses the giants overlook, SMBs, startups, and mid-market companies that need offshore software development with fast turnaround, transparent pricing, and full IP ownership in writing. Core work spans custom software, web platforms, e-commerce, and AI development. If you need a 50-person team for a five-year banking program, the enterprises below may fit better. If you need software shipped by an accountable senior team without enterprise overhead, that's exactly what we built MONA to do.

2. FPT Software — Best for Enterprise-Scale Programs

FPT Software is Vietnam's largest IT services company, founded in 1999 (some sources cite 1998) and headquartered in Hanoi. Press reports place it at 30,000+ employees across 30+ countries (source: figures aggregated on Wikipedia from company announcements), with offices spanning the Americas, Europe, and Asia-Pacific. Its official site lists clients including Airbus, Panasonic, Schaeffler, and Honda, and certifications including ISO 27001, TISAX, HITRUST, and ISO/IEC 42001 for AI management (source: fptsoftware.com). Strengths sit in large-scale digital transformation, cloud, and industry programs for automotive, manufacturing, banking, and healthcare. The trade-off: enterprise scale comes with enterprise process. Smaller engagements can feel like a small account at a very big firm.

3. TMA Solutions — Best for Telecom and Deep R&D

TMA Solutions is one of Vietnam's oldest software firms, founded in 1997 and headquartered in Ho Chi Minh City with ~4,000 engineers (source: tmasolutions.com; LinkedIn lists the 1,001–5,000 band). It holds CMMI Level 5, TL 9000, and ISO 27001 certifications (source: company site), and operates dedicated 5G, automotive software, IoT, and data centers plus a 600-engineer innovation campus in central Vietnam. TMA's heritage is telecom engineering. The TL 9000 certification is rare in this list, and it serves finance, e-commerce, healthcare, and logistics clients across the US, Canada, Europe, Japan, and Australia. Best fit: technically deep, long-running engineering programs rather than fast product sprints.

4. NashTech — Best for UK and European Enterprises

NashTech opened its first office in Hanoi in 2000 and is headquartered in London, with delivery centers in Ho Chi Minh City and Hanoi, a structure worth understanding: UK-facing management, Vietnamese engineering. Formerly part of Nash Squared (Harvey Nash), it was acquired by investment firm PAG in 2023 (source: Staffing Industry Analysts). The company reports 3,000+ people globally, including 2,000+ engineering specialists (source: nashtechglobal.com), and claims Vietnam's first CMMI Level 5 v2.0 appraisal alongside ISO 27001 and ISO 9001. It rates 4.7/5 from 12 reviews on Clutch. Strengths: custom software, cloud, and data work for insurance, retail, logistics, and education clients that want a Western-headquartered contract with offshore economics.

5. KMS Technology — Best for QA, Testing, and Healthcare Software

KMS Technology, founded in 2009, is headquartered in Atlanta, USA, with its main engineering hubs in Ho Chi Minh City and Da Nang. Its Vietnam operations passed 1,000 team members per the company's own announcements. That US-HQ structure means US-based account management and contracting on top of Vietnamese delivery. KMS is best known for software quality: QA and test engineering are core practice areas, alongside custom development, Salesforce, and generative AI work, with a dedicated healthcare unit (KMS Healthcare). It holds ISO/IEC 27001 (source: company press release) and rates 4.8/5 from 17 verified Clutch reviews, one of the strongest review bases among Vietnam-delivery vendors. Best fit: US companies, especially in healthcare, that want quality engineering as a first-class discipline.

6. Saigon Technology — Best for Agile Dedicated Teams

Saigon Technology was founded in 2012 (per its own site; third-party directories list 2010–2011) and runs ~400 staff across Ho Chi Minh City and Da Nang, with representative offices in the US, Australia, Singapore, and Switzerland (source: saigontechnology.com). It holds ISO 27001 and ISO 9001 and names clients including Standard Chartered Bank and Abbott on its website. Clutch shows 4.8/5 across 9 verified reviews. The company focuses on Agile dedicated teams for web and mobile development, cloud migration, and legacy modernization, serving healthcare, fintech, and logistics clients. It's also the most SEO-visible mid-size player in this space, a sign of consistent Western-market focus. Best fit: mid-size US/EU/AU companies wanting a stable dedicated offshore development team.

7. Savvycom — Best for Fintech and Digital Banking

7. Savvycom — Best for Fintech and Digital Banking (AI-generated illustration)

Savvycom, founded in 2009 and headquartered in Hanoi, reports 700+ technology professionals (source: savvycomsoftware.com; LinkedIn lists 501–1,000) with representative offices in the US, Australia, South Korea, Japan, Thailand, and Singapore. The firm reports 500+ projects delivered for 200+ clients across 30+ countries, with its strongest concentration in banking and finance, including digital banking platforms, ERP, and increasingly AI and blockchain work, plus healthcare, retail, and education. Its Clutch profile shows a 4.9/5 rating from 23 verified reviews, the highest well-sampled rating on this list. Founder-CEO Van Dang is one of Vietnam tech's most visible female founders. Best fit: fintech and banking-adjacent products where domain familiarity shortens discovery.

8. Orient Software — Best for Custom Web and Mobile Builds

Orient Software was established in 2005 (originally incorporated in Singapore) and is headquartered in Ho Chi Minh City, with additional offices in Da Nang, Hanoi, and Hue and representative offices in Singapore and Tokyo (source: orientsoftware.com). The company reports 330+ experts, and its Clutch profile (5.0/5, though from only 4 reviews) shows a service mix centered on web development (~40%) and mobile (~30%) alongside UX/UI, QA, cloud, and AI development. It has held ISO 9001 since 2012 (source: company press release). Orient also runs one of the largest English tech blogs of any Vietnamese vendor, evidence of long-term investment in the Western market. Best fit: well-scoped custom web and mobile application projects.

9. Rikkeisoft — Best for Japanese-Market Delivery

Rikkeisoft was founded in April 2012 by six engineers and is headquartered in Hanoi, having grown past 1,000 employees (source: Clutch and LinkedIn company profiles) with subsidiaries in Japan, the US, South Korea, and Thailand. Its DNA is the Japanese market. The founders met studying in Japan, and Japanese enterprise clients remain its core, which shows in its process discipline and BPO capabilities alongside AI, mobile, IoT, and cloud development. The company claims CMMI Level 3 and ISO 27001/9001 certifications (company-published; we couldn't independently verify against its site at the time of writing) and reports 500+ global customers with 97% retention (source: Clutch profile). Best fit: companies that value Japanese-grade delivery discipline, or Japan-market products specifically.

10. Sun* (Sun Asterisk) — Best for Startup Product Development

Sun* began as Framgia in 2012, rebranded in 2019, and listed on the Tokyo Stock Exchange (ticker 4053) in 2021. That makes it the only publicly listed company on this list besides FPT's parent. Legally headquartered in Tokyo, its development force of ~1,500 employees (source: company About page; Clutch describes 2,000+ total members) sits mainly in Hanoi, Da Nang, and Ho Chi Minh City. Sun* positions itself as a "digital creative studio": business design, prototyping, development, and growth support under one roof, plus an IT talent training arm producing ~2,000 trainees per year. Best fit: funded startups, especially those touching the Japanese market, that want product thinking bundled with engineering rather than pure staff augmentation.

How to Choose Between Offshore Software Development Companies in Vietnam

Ten good options is still nine too many for your project. Three filters cut the list fast:

Match company size to project size. A 30,000-person firm and a 300-person firm are different products. Enterprise programs with multi-year budgets belong at FPT, TMA, or NashTech scale. A product build, platform, or business system for an SMB or mid-market company gets more senior attention per dollar at a 250–700-engineer firm. That mismatch, not engineering skill, is behind most offshore disappointment.

Check what's verifiable, not what's claimed. Every vendor says "top talent" and "Agile." Instead ask: How many engineers are employed in-house? Which certifications can you show current documents for? Can I speak to two referenceable clients with projects like mine? Any serious vendor answers all three within a day. (Our full checklist is in the vendor-selection section of our offshore software development guide.)

Match the engagement model to the work. A fixed-scope build, a long-term offshore development center, and ongoing IT outsourcing services like maintenance and QA are different contracts with different management demands. Decide which you're buying before comparing prices, or you'll compare quotes for three different things.

Ready to Shortlist

If your project fits the SMB-to-mid-market profile, custom software, web platform, e-commerce, or AI development, delivered by an employed in-house team with your IP protected in writing, MONA is the #1 pick on this list for a reason we're happy to prove rather than assert. Get a free project estimate. We'll respond within one business day with an honest assessment, including telling you if one of the other nine companies above is actually the better fit for what you're building.
