Software & Mobile App Development Company in Vietnam
Mobile, web and AI development for Vietnamese businesses, with local payment wallets, Vietnamese-language UX and a near-identical working day.
- NDA & full IP ownership
- Senior engineers
- Working hours that overlap with Vietnam
Vietnam has some of the most mobile-native consumers in Southeast Asia: people order food, split bills, pay electricity and top up phones from a single QR scan. Founders and product heads in Ho Chi Minh City, Hanoi and Da Nang who want that kind of polished experience often lack the in-house capacity to deliver it on time. Sigmato is a software development company Vietnam businesses can bring in for exactly that gap: we design, build and maintain mobile apps, web platforms and AI features from our engineering centre in Bengaluru, working hours that sit almost on top of yours.
Where Vietnamese Companies Need Engineering Help
Vietnam’s economy has shifted quickly from low-cost assembly toward electronics, logistics, retail and financial services. That shift creates software demand in a few recurring shapes:
- Manufacturing and export suppliers around Hanoi, Bac Ninh and Binh Duong that need production dashboards, supplier portals and inspection tools, sometimes with computer vision for defect detection.
- Retail and social commerce brands selling through marketplaces and livestreams that now want their own store, loyalty app and customer data, typically on Shopify or a custom headless build.
- Fintech, lending and insurance teams launching wallets, eKYC onboarding and micro-insurance products under State Bank of Vietnam supervision.
- Tourism and hospitality operators in Da Nang, Hoi An and Phu Quoc that need booking engines and guest apps in Vietnamese, English, Korean and Chinese.
- Logistics and last-mile delivery firms tracking motorbike couriers through dense urban districts, which suits our on-demand delivery app experience.
Vietnam’s Data Rules Have Tightened: What That Means for Your App
Personal data handling in Vietnam moved from a decree-based regime to a full statute. Decree 13/2023/ND-CP introduced consent and impact-assessment obligations, and the Law on Personal Data Protection, in force from 1 January 2026, raises those requirements to the level of law with heavier penalties. Alongside it, the Cybersecurity Law and its implementing Decree 53/2022 can require certain online service providers to store specified data in Vietnam. In practice, we build:
- Granular, recorded consent screens written in plain Vietnamese, with separate opt-ins for marketing and for sensitive data such as health, location or financial details.
- Data inventories and processing records that make your impact assessment and any cross-border transfer assessment easier to prepare.
- Hosting choices that can keep production data on infrastructure in Vietnam when your legal advisers decide localisation applies.
- For banking and wallet apps, biometric verification flows aligned with State Bank requirements for higher-value online transfers, plus hardening against the OWASP Mobile Top 10 risks.
We are engineers, not lawyers, so we work alongside your counsel. Our AI data privacy checklist shows the kind of controls we put in place by default.
Payments, Super-Apps and the Vietnamese Phone Market
Cash is still common, but QR payments have spread fast, and a checkout that only accepts international cards will lose most local customers. We integrate the methods Vietnamese users actually pick:
| Method | Where it fits |
|---|---|
| MoMo and ZaloPay wallets | Consumer apps, food, ride-hailing, subscriptions |
| VNPay QR and bank QR via NAPAS | Retail checkout, bill payment, bank-to-bank transfers |
| Domestic ATM cards (NAPAS) | E-commerce for customers without credit cards |
| Visa, Mastercard, Apple Pay | Travel, cross-border sales and premium segments |
| Cash on delivery | Marketplaces and first-time buyers outside big cities |
Android holds the larger share of handsets, with a wide spread of mid-range devices, while iPhone users concentrate in higher-income urban segments. We therefore test on a realistic device matrix and keep app sizes lean. Zalo is the default messaging channel for many customers, so Zalo Official Account notifications and Zalo login often outperform email for retention. Cross-platform frameworks such as Flutter (see the official Flutter documentation) let us ship both platforms from one codebase without compromising performance on budget phones.
Getting Vietnamese Localization Right
Vietnamese uses the Latin alphabet with stacked diacritics, which breaks naive search, sorting and fonts. We apply Unicode normalization so that “Hà Nội” and “Ha Noi” both match, choose typefaces that render tone marks cleanly, and allow for longer labels than English. Prices display in Vietnamese dong without decimals, addresses follow ward-district-province order (updated for the 2025 administrative merger of provinces), and dates use day-month-year.
Time Zone: Practically the Same Working Day
Vietnam (UTC+7) is only ninety minutes ahead of our Bengaluru team. When your office opens at 8:30, we are already online; when you finish, we are wrapping up as well. That means live stand-ups, same-day bug fixes and pair sessions without anyone working late. Our UK branch adds coverage if you also sell into Europe.
How a Typical Engagement Runs
- Free call and NDA. We discuss your users, market and constraints.
- Written proposal. Scope, stack, milestones and a fixed or time-and-material quote in USD, with VND equivalents if useful for internal approval.
- Design in Figma. Vietnamese-first screens tested with real users before development.
- Two-week sprints. Working builds, demos and a shared backlog.
- Launch and care. App Store and Google Play release, monitoring and optional support retainers.

Frequently Asked Questions
Why hire a team in India when Vietnam has its own outsourcing industry?
Many local studios are busy with export work for Japanese, Korean and US clients, so lead times can be long. We add capacity quickly, bring experience across AI, SaaS and e-commerce, and can complement a Vietnamese team rather than replace it.
Can you integrate MoMo, ZaloPay and VNPay in one checkout?
Yes. We usually connect through each provider’s merchant API or a local payment gateway, then handle callbacks, refunds and reconciliation in a single backend so finance sees one ledger.
Does my app have to store data inside Vietnam?
It depends on your service type and the data involved. Localization duties under the cybersecurity rules apply to particular categories of providers. We can architect for local hosting either way and recommend confirming the requirement with a Vietnamese lawyer.
What does a mobile app cost?
As an indicative range, a focused MVP usually lands between US$15,000 and US$50,000, while wallet-style or marketplace apps with several integrations run higher. The final quote depends on scope, and our mobile app development cost guide breaks down the drivers.
