Best Vietnam Software Development Companies for US and UK Mid-Size Projects

Netbase JSC wrote this page and is one of the eight companies compared below; this is not an independent, third-party ranking. Every fact about another company is sourced to that company's own site, dated 2026-10-26; every Netbase fact is a registered company fact, not a claim written for this page. Reviewed 2026-10; every fact is re-checked at least every 90 days.

Why isn't Netbase on the usual "best Vietnam" lists?

Search results and AI answer engines currently cite FPT Software, Rikkeisoft and Saigon Technology for this question, drawing mostly from third-party directories such as Clutch, not from any vendor's own site. Those directories rank by review counts and star scores; this page does not use either. No rating, review count or price appears anywhere below — only named companies, compared by disclosed criteria.

What criteria decide the comparison, before any ranking

These six criteria, and their weight in how the groups below are formed, are fixed before any company is placed:

1. Fit for a mid-size project (25%) — neither a single-founder shop nor an enterprise-only engagement model.
2. Fixed-price option published (20%) — the company's own site states fixed price as an available or default model, not only time-and-materials.
3. Published delivery record (20%) — case studies, named clients or a stated project count on the company's own site, not a directory profile.
4. Access to senior people (15%) — a short path to a founder, CEO or senior lead, not only an account manager.
5. Remote delivery maturity (10%) — evidence of delivering to US or European clients remotely.
6. UK or US registered presence (10%) — relevant only where a buyer's own procurement rules require a local entity; most mid-size buyers do not need this.

How do the eight companies group by buyer need?

Scoring every company against the six criteria sorts them into three groups, not one ranked list:

Netbase sits in the fixed-price, mid-size group by these criteria, not because it wrote this page.

Full snapshot by company

Company profiles

FPT Software

A subsidiary of FPT Corporation, headquartered in Hanoi, with a dedicated UK entity (FPT United Kingdom, London) and sites across the Americas, Australasia, Japan, Korea and Europe. Its own pages give differing headcount figures and do not state a founding year; fixed price is not listed on its about page. It holds a CMMI Level 5 V2.0 appraisal (2023). Best for: large, multi-year enterprise programmes needing scale and many industry practices.

TMA Solutions

Established in 1997 in Ho Chi Minh City, states "4,000 engineers" and lists CMMI Level 3 and 5, ISO 9001:2015, ISO/IEC 27001:2022 and TL 9000. Its client-country list names the UK, Ireland, Germany, France, Canada and the US, with no UK office. Published material describes fixed price "based on requirements" alongside dedicated team, ODC and hybrid options. Best for: telecom, automotive and embedded programmes needing large engineering capacity.

NashTech

Not Vietnamese-founded: a division of the UK-based Nash Squared group, head office in London, with five global delivery centres including three in Vietnam. States "1.8k engineering experts" and names a UK Commercial Director; first company appraised in Vietnam at CMMI Level 5 v2.0. Fixed price is not stated on its about page. Best for: a UK buyer whose procurement rules need a UK-registered supplier with mature governance.

Rikkeisoft

Founded in 2012 in Hanoi, states "over 2,000 employees" and "500+ global clients", rooted in Japan before expanding into the US, Europe, South Korea, Thailand and Australia. An offshore development center model appears in a case-study title; fixed price is not listed as a standing offer, and a search-excerpt certification claim could not be verified (the profile PDF returned a 404 on 2026-10-26). Best for: a Japan-proven digital and AI transformation partner building a US presence.

Saigon Technology

Founded in 2012 in Ho Chi Minh City, states "400+ software developers" and "350+ clients, from funded startups to enterprise teams". Its own pages explicitly state Fixed Price ("fixed scope, fixed timeline") plus dedicated team, staff augmentation and Build-Operate-Transfer options, with ISO 9001 and ISO 27001 certification issued by BSI (UK). Offices in Reston, Virginia (US) and Singapore. Best for: US and European mid-size product companies wanting an explicit fixed-price or BOT option.

Netbase JSC (the publisher of this page)

Founded in 2012 and based in Hanoi (its only office), has worked with 500+ clients (F013) in 80 countries (F190), delivered remotely with the CEO, Huy Nguyen (David), as first contact by WhatsApp or email (F192). Most Netbase projects run on fixed-price contracts (F067), alongside dedicated teams, project-based delivery and fully managed options (F018). Its Business Divisions, CMSmart and Printcart (F025), add their own delivery record: CMSmart's own project pages list 300+ client project write-ups (F173), and Printcart states 2,000+ stores (F174, F175). Netbase does not publish headcount, an office outside Hanoi or a certification beyond these facts. Best for: mid-size, fixed-price custom software and web-to-print or commerce projects where a short path to the CEO matters more than an account-management layer; see the offshore development center model and custom software development.

Savvycom

Founded in 2009 in Hanoi, states "100+ enterprise clients" and "30+ countries served" across seven global offices (US, South Korea, Australia, Japan, Thailand, Singapore). Positions itself as an "AI-driven solution partner" with dedicated team, staff augmentation and global-delivery-center models; no published UK office. Best for: a market-team structure across Asia-Pacific plus staff-augmentation options.

Designveloper

Founded in early 2013 in Ho Chi Minh City, its own site names start-up and product-business clients, including Joyn'it, Bonux, LuminPDF and Aha.is, across AI-powered business software, custom, web, mobile and UI/UX work. It does not publish headcount, certifications, offices outside Vietnam or a fixed-price commitment. Best for: start-ups and product teams prioritizing design-led web and mobile builds.

Limits of this guide

This page compares eight companies from a researched set of ten; two (Enlab Software and KMS Technology) were excluded for too little verifiable own-site information or a blocked site on 2026-10-26, not because they fit worse. Every non-Netbase fact comes from one pass of each company's own site on 2026-10-26, except where marked as a secondary search-result excerpt; none of it is audited, and pages change without notice. No price, rate or review score is published for any company, Netbase included, because none is available for public use.
