Website designers and developers for Vietnamese businesses Vietnamese first, English second, from India.

SpikeSecure Technologies Pvt. Ltd., a website design and development company in Coimbatore, India, designs and builds websites for businesses in Vietnam: Vietnamese-first corporate sites with an English edition, export catalogues and dealer portals for manufacturers, campaign pages for Ho Chi Minh City and Hanoi audiences, property project sites and WordPress or Next.js builds, with VNPay, MoMo and Napas payments where a site sells, invoiced in USD from our published Indian ranges and hosted in Singapore or Vietnam in accounts you own.

A Vietnamese site has to render full diacritics in every font, format VND without decimals, show ward, district and province addresses, offer Zalo alongside phone and email, and satisfy Decree 13 consent rules on forms. We build those in, write the English edition for international buyers, and keep a six-hour overlap with your afternoon from Coimbatore; there is no Vietnam office and we do not claim one.

• Typical budget: ₹1–3 lakh for a corporate website with a CMS, SEO setup, forms and analytics.
• Where the team is: Coimbatore, Tamil Nadu, India; ICT (UTC+7). No office in Vietnam; delivery and support are remote, with a 11:00–17:00 ICT live overlap.
• Who it is for: manufacturers and exporters, F&B chains, ecommerce brands, tourism and hospitality operators, real estate developers, clinics, schools and startups in Ho Chi Minh City, Hanoi, Da Nang and Hai Phong.
• Localised for: Vietnamese first with full diacritics, English as the second language; USD invoicing with local amounts shown as indicative conversions; VNPay, MoMo, ZaloPay, ShopeePay, Napas cards and VietQR; Zalo and WhatsApp notifications; 10% VAT with mandatory e-invoices connected to the tax authority.
• Indicative cost: business websites from ₹40,000, corporate sites ₹1–3 lakh, web applications from ₹3 lakh on our published Indian pricing, roughly USD 500–4,500 (about VND 14–116 million) at the time of writing (October 2026), confirmed in a fixed-scope proposal.
• Hosting and data: AWS or Google Cloud Singapore, or Viettel IDC, VNPT Cloud or FPT Cloud where data residency is required, in accounts you own; designed for Decree 13/2023 on personal data protection and the Personal Data Protection Law that follows it, plus the Cybersecurity Law's localisation duties.
• Start: Book a discovery call; written proposal within 48 hours; mutual NDA before discovery.

Who looks for website designers in Vietnam

Manufacturers and exporters in Binh Duong, Dong Nai and Bac Ninh who need an English catalogue that wins foreign buyers; F&B chains and franchises with ordering and loyalty on the web; ecommerce brands that sell on Shopee, Lazada and Tiki but want their own store; tourism operators in Da Nang and Hoi An with booking pages; and property developers with project microsites.

Vietnamese first, English second

Vietnamese is the primary edition: fonts that carry every diacritic, dd/mm/yyyy dates, VND formatting, ward–district–province address forms, Zalo click-to-chat and VietQR payment prompts. The English edition is written for investors and foreign customers rather than translated line by line. Vietnamese copy is supplied or approved by you or your translation partner; hreflang links the two editions.

Search and hosting

Google and Cốc Cốc serve Vietnamese searches, and AI assistants answer “công ty thiết kế web” style questions directly; every build ships with technical SEO, structured data, llms.txt and answer-ready content so the site ranks for Ho Chi Minh City, Hanoi and Da Nang searches and is cited by AI answers. Hosting goes to AWS or Google Cloud Singapore for speed, or to Viettel IDC, VNPT or FPT Cloud where Vietnamese data residency is required, in your accounts.

• Payments. 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.
• Accounting and CRM. 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.
• 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.
• What already runs in production. 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 hold no SOC 2 or ISO 27001 certification.

SpikeSecure has one office, at CHIL SEZ IT Park, Saravanampatti, Coimbatore, India. Vietnamese clients are served remotely by that engineering team; there is no Vietnam office, entity, local staff or local phone number, and we do not claim one.

• Working hours. 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. Tết and other public holidays are written into schedules, and launch or incident coverage outside the window is arranged in the maintenance plan.
• Commercials. A written, fixed-scope proposal before work starts. Quoted and invoiced in USD through Wise or Stripe, or in INR; Vietnamese dong figures in proposals are indicative conversions and the fixed price is set in the invoicing currency. We are an Indian entity and charge no Vietnamese VAT; your accountant advises on foreign-contractor tax treatment on your side, and we do not give tax advice.
• NDA and ownership. A mutual NDA is signed before discovery. Source code lives in a GitHub organisation you own; cloud, app store, payment and domain accounts are in your name from day one; the intellectual property in the delivered work is assigned to you on final payment.
• Communication. A named project lead, a shared channel on Zalo or Slack, weekly demos on a staging URL (recorded for absent stakeholders), a written status note every Friday and GitHub access throughout.
• Hosting. 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.
• After launch. A 30-day warranty on every build, then optional maintenance with monthly health reports, or a documented handover to your in-house team or a Vietnamese vendor.
