Direct answer
Can Vietnamese businesses outsource software development to SpikeSecure in India?
Yes. SpikeSecure Technologies Pvt. Ltd. is an Indian software development company based in Coimbatore that Vietnamese manufacturers, F&B chains, ecommerce brands and startups outsource development to. You can commission a fixed-scope project or hire Indian software developers as a dedicated team. We build web applications, websites, mobile apps, ecommerce stores and marketplaces, CRM and ERP systems, SaaS products, streaming and community apps, and AI features for Vietnamese startups, SMEs, agencies and enterprises, as fixed-scope projects or dedicated teams, under a mutual NDA, with weekly demos, source code and IP owned by you, and a 30-day warranty. We have no office, staff or entity in Vietnam and do not claim any.
What differs from a local agency is cost and time-zone shape, not the engineering: our published Indian ranges are the starting point for every proposal, invoicing is in USD, deployments go to AWS or Google Cloud Singapore, or a Vietnamese provider such as Viettel IDC, VNPT or FPT Cloud where data residency is required, in accounts you own, and integrations use the payment, accounting and delivery tools Vietnamese businesses already run. Vietnam is on Indochina Time (UTC+7), one and a half hours ahead of India, so our 09:30–18:30 IST day runs 11:00–20:00 in Vietnam and overlaps your working day from 11:00 to 17:00, with the common 11:30–13:30 lunch break planned around; morning requests are answered by 11:00 your time. Launch and incident coverage outside that window is arranged in the maintenance plan.
- Based in: Coimbatore, India; Vietnam served remotely. No local office is claimed.
- Working overlap: Vietnam is on Indochina Time (UTC+7), one and a half hours ahead of India.
- Currency and invoicing: USD, invoiced through Wise or Stripe; INR if you prefer. Vietnamese dong (VND) amounts in proposals are indicative conversions; the fixed price is set in the invoicing currency.
- Hosting: AWS or Google Cloud Singapore, or a Vietnamese provider such as Viettel IDC, VNPT or FPT Cloud where data residency is required, in accounts you own.
- Integrations commonly requested: VNPay, MoMo, ZaloPay and ShopeePay wallets, Napas domestic cards and VietQR bank transfers, OnePay and Payoo gateways, Visa and Mastercard, and cash on delivery, which remains common in Vietnamese ecommerce.
- Evidence: six published Indian case studies and our own products (Local Friends, SpikeSecure and SpikeSEO WordPress plugins); no Vietnamese clients are named.
- Also searched as: software development company for Vietnam, outsource software development to India from Vietnam, hire software developers from India for Vietnamese companies, app development company for Ho Chi Minh City businesses, offshore development partner Vietnam.
- Product evidence: Local Friends, SpikeSecure’s own calling platform, is the running proof for Vietnamese teams: Local Friends supplies the tested calling, live-room, wallet and moderation modules: Agora audio and video, Flutter apps, a Next.js web front end, a NestJS back end and payouts, extended with Vietnamese UI, Zalo notifications and VNPay or MoMo top-ups.

Why an India-based team
Why Vietnamese companies build with SpikeSecure.
Cost without the trade-offs
A Coimbatore cost base, one Flutter codebase for both stores, open-source stacks and reusable modules from our own products put our published ranges well below most local agency quotes for the same scope.
An established team, not a marketplace
The same engineering team since 2018, 50+ delivered projects, our own products in production (Local Friends, SpikeSecure and SpikeSEO plugins) and named case studies you can check.
Accountability in writing
Fixed scope, dated milestones, acceptance criteria, weekly demos and a 30-day warranty, so remote does not mean unaccountable.
You keep everything
Code, accounts, infrastructure and IP are yours from day one; there are no licence fees or lock-in on custom builds.
Built for AI search
Every web deliverable ships with structured data, llms.txt and answer-first content, the same practice that gets our own site cited by AI assistants.
Honest about limits
We have no office, staff or entity in your country and say so. Where a local vendor is the better choice, for example on-site hardware work, we tell you.
Delivery model
How a Vietnam project runs with a team in Coimbatore.
SpikeSecure has one office, at CHIL SEZ IT Park, Saravanampatti, Coimbatore, India. Vietnamese clients are served remotely by that engineering team.
- Time zones. Vietnam is on Indochina Time (UTC+7), one and a half hours ahead of India, so our 09:30–18:30 IST day runs 11:00–20:00 in Vietnam and overlaps your working day from 11:00 to 17:00, with the common 11:30–13:30 lunch break planned around; morning requests are answered by 11:00 your time. Launch and incident coverage outside that window is arranged in the maintenance plan.
- Communication. A named project lead, a shared channel on Slack or WhatsApp, weekly demos on a staging URL (recorded for absent stakeholders), a written Friday status note and GitHub access throughout.
- Commercials. A written fixed-scope proposal before work starts; USD, invoiced through Wise or Stripe; INR if you prefer. Vietnamese dong (VND) amounts in proposals are indicative conversions; the fixed price is set in the invoicing currency.
- NDA and ownership. A mutual NDA before discovery; repositories, cloud, app store and domain accounts in your name; IP in the delivered work is yours.
- Hosting and integrations. AWS or Google Cloud Singapore, or a Vietnamese provider such as Viettel IDC, VNPT or FPT Cloud where data residency is required, in accounts you own; VNPay, MoMo, ZaloPay and ShopeePay wallets, Napas domestic cards and VietQR bank transfers, OnePay and Payoo gateways, Visa and Mastercard, and cash on delivery, which remains common in Vietnamese ecommerce.
- After launch. A 30-day warranty, then optional maintenance with monthly health reports, or a documented handover to your team or local vendor.
Vietnam context
Working with Vietnamese businesses: industries, ecosystem and compliance.
Who hires us from Vietnam
Manufacturers and exporters needing ERP, quality and dealer portals, F&B chains and franchises needing ordering and loyalty apps, ecommerce brands selling alongside Shopee, Lazada and Tiki, fintech and edtech startups, tourism and hospitality operators, logistics companies and real estate developers.
Ecosystem
Consumer products need Vietnamese as the primary language with English as a switch, VNPay, MoMo, ZaloPay and Napas as payment rails, VietQR for transfers and Zalo alongside SMS for notifications. Deployments go to Singapore cloud regions, or to Vietnamese providers when your compliance advisers require in-country hosting.
Compliance
Decree 13/2023 on personal data protection and the 2025 Personal Data Protection Law set consent, cross-border transfer and impact-assessment duties, and the Cybersecurity Law adds data-localisation rules for some services; VAT is 10% at the time of writing (with temporary reductions) and e-invoicing is mandatory. We implement what your advisers specify and do not give tax or legal advice.
Language and localisation
Vietnamese and English interfaces with full diacritics support, Vietnamese address and name formats, VND formatting without decimals and dd/mm/yyyy dates, using Vietnamese copy supplied or approved by you or your translation partner.
Market factors
What changes when we build for Vietnam.
Building for Vietnam is not a matter of translating an Indian product. These are the market factors SpikeSecure designs for on every Vietnamese project, stated as of the time of writing; regulations change, so your local advisers confirm your obligations and we implement them in the software.
- Language: Vietnamese first with full diacritics support, fonts that carry Vietnamese glyphs, dd/mm/yyyy dates and ward, district and province address formats, plus an English switch; Vietnamese copy is supplied or approved by you or your translation partner.
- Currency: Vietnamese dong (VND) with no decimals and dot thousands separators in the product; proposals fixed in USD with VND shown as an indicative conversion.
- Tax and invoicing: VAT of 10% on most goods and services, with temporary reductions on some categories, and mandatory electronic invoices connected to the tax authority; we configure the software as your accountant instructs and invoice from India.
- Payments: VNPay, MoMo, ZaloPay and ShopeePay wallets; Napas domestic cards and VietQR bank transfers; OnePay and Payoo gateways; Visa and Mastercard; cash on delivery, which remains the largest ecommerce payment method.
- Delivery: Giao Hang Nhanh, Giao Hang Tiet Kiem, Viettel Post and J&T Express integrations, Grab Express for same-day in Ho Chi Minh City and Hanoi, with cash-on-delivery reconciliation.
- Data protection: Decree 13/2023 on personal data protection and the 2025 Personal Data Protection Law: consent, impact assessments and cross-border transfer dossiers; the Cybersecurity Law adds data-localisation duties for some services. Implemented as configuration and process defined by your advisers.
- Hosting: AWS or Google Cloud Singapore by default, or Viettel IDC, VNPT, FPT Cloud or CMC Cloud when data must stay in Vietnam, in accounts you own.
- Working week: Monday to Friday with many Saturday mornings; a common 11:30–13:30 lunch break; Vietnam is on UTC+7, so our 09:30–18:30 IST day is 11:00–20:00 Vietnam time and we overlap 11:00–17:00. Tết (late January or February) pauses most client work for one to two weeks and is planned into every schedule.
- Communication: Zalo is the primary customer channel, with Zalo Official Account notifications, brand-name SMS and Facebook alongside; Vietnamese app-store listings are part of scope.
- Sectors we see: Manufacturers and exporters needing ERP and dealer portals, F&B chains and franchises, ecommerce brands selling alongside Shopee, Lazada, Tiki and TikTok Shop, fintech and edtech startups, tourism and hospitality, logistics and real estate.

Project process
The Vietnam project process, step by step.
The same six steps on every engagement, scheduled around the agreed overlap window.
01
Discovery — week 1
Two or three video sessions in the agreed Vietnam overlap window under a mutual NDA, mapping users, integrations and constraints; a fixed-scope written proposal follows, usually within 48 hours of the last session.
02
Design — weeks 2–3
Wireframes, a design system and a clickable prototype reviewed with your stakeholders before any code is written.
03
Build — week 3 onwards
Weekly demos on a staging URL, GitHub access from day one, a written Friday status note and a shared channel for questions.
04
Test — final weeks
Functional, performance, accessibility and security testing against a pre-launch checklist you sign off in writing.
05
Launch
Deployment to AWS or Google Cloud Singapore, or a Vietnamese provider such as Viettel IDC, VNPT or FPT Cloud where data residency is required, in accounts you own, monitoring and backups configured, and a launch-week watch with you.
06
Support
30-day warranty, then optional maintenance with monthly reports, or a documented handover to your team.

Mutual NDA first
Signed before any brief is shared, on your template or ours; no sub-contractors without written consent.
02
Source code and IP are yours
Repositories, cloud accounts, app store listings, domains and design files are created in your name; we hold no licence over the delivered work.
03
Security baseline
HTTPS with HSTS, security headers, OWASP Top 10 review, role-based access, encrypted secrets, audit logs, dependency scanning and a penetration test before launch on client-facing systems.
04
Data handling
Data stays in the cloud region you choose. We implement the data-protection, retention and consent requirements your compliance advisers specify; we do not give legal advice.
05
Performance and accessibility
Core Web Vitals targets, WCAG 2.1 AA checks, and SEO and AEO fundamentals on every web deliverable.
06
Continuity
Documentation, infrastructure as code, tested backups and a recorded handover, so your team or another vendor can operate the system without us.
Pricing methodology and timelines
How we price and schedule for Vietnamese clients.
01
Fixed-scope projects
One written price for a defined scope, paid in milestones (typically 30% on start, 40% at design sign-off, 30% at launch); change requests are quoted before they are built.
02
Dedicated teams
Monthly rate per developer or designer by seniority, minimum three months, project lead included above three people, 30 days' notice to scale.
03
Starting point
Our published Indian ranges: websites ₹1.5–4 lakh, ecommerce ₹1.5–15 lakh, mobile apps ₹4–20 lakh, custom software and web applications ₹3–25 lakh, marketplaces ₹6–40 lakh. Conversions shown on our pages are indicative.
04
Timelines
Websites 4–10 weeks, ecommerce 6–12 weeks, mobile apps 12–20 weeks, custom software and SaaS 12–24 weeks, with dated milestones in every proposal and a pilot release where possible.
05
Running costs
Cloud hosting, third-party APIs and app store fees are paid by you directly at cost; maintenance retainers start after the 30-day warranty, from ₹15,000 a month.
06
No local taxes charged by us
We invoice as an Indian entity; treatment of our invoices under your local tax rules is for your accountant to advise. We do not give tax advice.
Country-specific proof
What we set up for Vietnamese clients, and what already runs in production.
01
Payments, in your accounts
VNPay, MoMo, ZaloPay and ShopeePay wallets, Napas domestic cards and VietQR bank transfers, OnePay and Payoo gateways, Visa and Mastercard, and cash on delivery with rider reconciliation, which remains common in Vietnamese ecommerce. Set up in accounts you own, with webhooks, refunds and settlement reconciliation tested in the sandbox before go-live.
02
Accounting and CRM sync
MISA, Fast or Bravo accounting through export or API where the vendor offers one, Xero or QuickBooks Online for foreign-owned companies, and Vietnamese e-invoices through a licensed provider such as Viettel, VNPT or MISA meInvoice as the tax rules require; Zoho CRM or HubSpot through their APIs for sales teams.
03
Cloud and data residency
AWS or Google Cloud Singapore for most workloads, or Viettel IDC, VNPT Cloud or FPT Cloud where Vietnamese data residency is required, in your accounts with your billing; encrypted Postgres, object storage and a CDN with Hanoi and Ho Chi Minh City edge locations in front.
04
Privacy and compliance we design for
We design for Decree 13/2023 on personal data protection and the Personal Data Protection Law that follows it (consent, impact assessments, cross-border transfer records), the Law on Cybersecurity's data-localisation duties for the services it names, mandatory e-invoicing under Decree 123/2020, State Bank of Vietnam rules where the product holds or moves customer money (you or a licensed partner hold the licence, not us), and Vietnamese-first interfaces with English as the second language, at the time of writing (September 2026). Your counsel signs off; we implement.
05
Local channels and APIs
Vietnamese and English UI, Zalo Official Account and Zalo Notification Service for messaging alongside SMS brand-name gateways, Giao Hàng Nhanh, Giao Hàng Tiết Kiệm and Viettel Post APIs for delivery, and Google Maps for Hanoi, Ho Chi Minh City and Da Nang delivery zones; all in your accounts.
06
Production proof, and how to verify us
What already runs in production, and is the pattern we reuse: per-minute wallets, Razorpay checkout and RazorpayX payouts, Agora audio and video, Flutter and Next.js clients and a NestJS API on AWS in Local Friends; Razorpay checkout, WhatsApp Business API follow-ups and role-based dashboards in the six published case studies. Swapping Razorpay for VNPay or MoMo is a gateway adapter and a sandbox test run, not a new architecture. No Vietnamese client is named on this site and we do not hold SOC 2 or ISO 27001 certification; we say both plainly. What you can check: Local Friends running live, six published case studies with client quotes, the security baseline on this page, and references relevant to your sector on the discovery call. Any specific number we quote is traceable to a source or labelled indicative.
FAQ
Working with SpikeSecure from Vietnam: your questions answered.
Does SpikeSecure serve Vietnam?
Yes. SpikeSecure is based in Coimbatore, India and serves Vietnamese clients remotely: web applications, mobile apps, ecommerce, SaaS products and AI features on fixed-scope proposals or dedicated teams, under a mutual NDA with weekly demos and source code you own.
Where is SpikeSecure based?
SpikeSecure Technologies Pvt. Ltd. is based at CHIL SEZ IT Park, Saravanampatti, Coimbatore, Tamil Nadu, India. It has one office and serves every international market, including Vietnam, remotely from there.
How does outsourcing software development to India work for a Vietnamese company?
A mutual NDA first, then a fixed-scope written proposal in USD within 48 hours. Our day overlaps yours from 11:00 to 17:00 Vietnam time for stand-ups and demos, morning requests are answered by 11:00, Tết is planned into every schedule, and code, cloud and payment accounts are created in your company's name.
Does SpikeSecure have an office in Vietnam?
No. SpikeSecure has one office, in Coimbatore, India, and serves Vietnamese clients remotely. We do not have Vietnamese staff, a Vietnamese entity or a local phone number, and we do not claim any.
Can you integrate VNPay, MoMo, ZaloPay and Napas?
Yes. We integrate VNPay, MoMo, ZaloPay and ShopeePay wallets, Napas domestic cards, VietQR transfers and the OnePay and Payoo gateways, alongside Visa and Mastercard and cash on delivery, through merchant accounts in your company's name.
How does the time difference with Vietnam work?
Vietnam is one and a half hours ahead of India, so our office hours are 11:00–20:00 Vietnam time and we overlap your working day from 11:00 to 17:00. Morning requests are answered by 11:00 your time and demos are scheduled in your afternoon.
Do you build Vietnamese-language products?
Yes. Vietnamese-first interfaces with an English switch, full diacritics, local address and date formats and VND formatting are standard; the Vietnamese copy itself comes from you or a translation partner you approve, and we implement it exactly.
How much does development cost for a Vietnamese company?
Proposals are fixed in USD from our published Indian ranges: websites ₹1.5–4 lakh, mobile apps ₹4–20 lakh, ecommerce ₹1.5–15 lakh, custom software ₹3–25 lakh, roughly USD 1,800 to 30,000 at the time of writing and marked as indicative until the written proposal.
Do you integrate Zalo?
Yes. Zalo Official Account notifications and Zalo login are built into Vietnamese consumer products where you hold the Zalo business account, alongside brand-name SMS and email, because Zalo is the channel most Vietnamese customers actually read.
Can our data stay in Vietnam?
Yes. When your advisers require in-country hosting under the Cybersecurity Law or the personal-data rules, we deploy to Viettel IDC, VNPT, FPT Cloud or CMC Cloud in accounts you own; otherwise AWS or Google Cloud Singapore is the default for latency and cost.
How do you handle Tết and Vietnamese holidays?
Every schedule marks Tết and the public holidays as a freeze on client-side decisions and releases. Development continues in India during that period and demos resume on the first working day after the holiday.
Can you connect our store to Shopee, Lazada or TikTok Shop?
Where the marketplace exposes a seller API or an approved connector, we synchronise catalogue, stock and orders between your own store and those channels; where it does not, we build the import and export workflows your operations team needs. Scope is confirmed in the proposal after checking the current API terms.
Which Vietnamese payment, messaging and delivery systems do you integrate?
VNPay, MoMo, ZaloPay, ShopeePay, Napas cards and VietQR transfers, OnePay and Payoo, cash on delivery; Zalo OA and ZNS plus SMS brand-name gateways for messaging; GHN, GHTK and Viettel Post for delivery; MISA, Fast or Bravo accounting and licensed e-invoice providers as the tax rules require. Set up in your accounts and tested in each vendor's sandbox first. The same wallet, checkout and payout pattern already runs in production on Razorpay in Local Friends and our published case studies.
How does remote development work in practice?
A named project lead, a shared Slack or WhatsApp channel, weekly demos on a staging URL in the agreed overlap window, a written Friday status note, GitHub access from day one and a pre-launch checklist you sign off. Decisions are captured in tickets so nothing depends on being in the same room.
How long does development take?
Websites 4–10 weeks, ecommerce 6–12 weeks, mobile apps 12–20 weeks, custom software and SaaS 12–24 weeks. Each proposal carries dated milestones and a pilot release usually goes live before the full scope.
Who owns the source code and IP?
You do. Repositories, cloud accounts, app store listings and domains are created in your name from day one and the intellectual property in the delivered work belongs to you; there are no licence fees on custom builds.
Can you sign an NDA?
Yes. A mutual NDA is signed before discovery, on your template or ours, and sub-contractors are never used without your written consent.
How are projects managed?
Fixed written scope, dated milestones, weekly demos, a Friday status note, GitHub access, acceptance criteria and a 30-day warranty; change requests are quoted in writing before they are built. Dedicated teams follow your roadmap in two-week releases.
What services does SpikeSecure offer Vietnamese clients?
Custom software and web applications, websites, mobile apps, ecommerce and marketplaces, CRM and ERP, SaaS products, OTT and live streaming, healthcare, real estate, matrimonial, dating and astrology apps, AI features, and SEO and AEO services, plus dedicated developers. Each has its own service page linked from this hub.
Can SpikeSecure build ecommerce, mobile, SaaS, AI, OTT, real estate, matrimonial or astrology applications for Vietnam?
Yes. All of these are existing SpikeSecure services with published scope, pricing ranges and process, delivered to Vietnamese clients under the same NDA, fixed-scope and ownership terms; the service cards above link to each page.
