The case for a custom e-commerce platform in Hai Phong
Hai Phong is a centrally-governed city of vietnam, where around 2.1 million people live and shop, and one of the markets in Vietnam where we build custom e-commerce platforms.
The local economy is driven by port and electronics manufacturing, and commercial activity concentrates around the port and industrial zones.
Logistics are supported by Hai Phong port and Cat Bi Airport, which matters when you promise customers fast delivery.
Vietnam is one of the fastest-growing e-commerce markets in Asia, driven by young urban shoppers. Cash on delivery remains common, but QR and wallet payments are rising quickly.
For a business in Hai Phong, the opportunity is to own the customer relationship: your own custom e-commerce platform keeps your margin, your data and your brand, while marketplaces and social channels become additional sales routes instead of the only one.
Localised for Hai Phong, not translated into it
A store that works in Hai Phong respects local habits as well as local law. These are the details we configure first.
Currency and pricing
Prices, taxes, shipping and refunds are shown in Vietnamese đồng (VND), formatted the way Hai Phong customers read them.
Language and content
Content can be produced in Vietnamese, so a Hai Phong customer reads the store in the language they use at home.
Local trust signals
We add the payment logos, courier names and policy pages shoppers in Hai Phong recognise: cash on delivery and MoMo and delivery through Vietnam Post (VNPost).
Domain, phone and contact
A .vn domain (or your own) builds local trust and search relevance. Contact buttons are pre-set with +84, so a customer in Hai Phong taps once to call or message.
Talent and partners nearby
Hai Phong draws on Hai Phong University, which means plenty of local staff, interns and technology partners to run the store after launch.
Custom-built for how you sell in Hai Phong
Whatever your business sells in Hai Phong, N&T Software designs and develops the custom e-commerce platform and the matching mobile app exactly to your requirements — your catalogue, your prices, your payment and delivery rules.
Typical clients include multi-brand groups, businesses outgrowing SaaS platforms, companies migrating legacy stores and regulated sectors. Categories that sell especially well online in Vietnam — fashion, beauty, electronics and mother and baby — get catalogue structures and filters designed for them.
We start with a requirements meeting, show you a working demo within 24 hours, and only then propose scope, milestones and budget.
Core modules we build for Hai Phong clients
These are the building blocks of a custom e-commerce platform. We scope them with you, so you pay for what your Hai Phong operation needs.
Custom workflows
Product configurators, made-to-order flows, approvals, contracts and industry-specific rules. Bulk import and sync tools mean the Hai Phong team never re-keys stock, prices or descriptions by hand.
Headless architecture
API-first commerce with a fast front end, so web, app, kiosk and marketplace channels share one backend. Payment steps are built around cash on delivery, MoMo and ZaloPay, the options shoppers here already trust.
Multi-entity operations
Multiple brands, companies, warehouses, currencies and tax registrations on one platform. Couriers such as Vietnam Post (VNPost), Giao Hàng Nhanh (GHN) and Giao Hàng Tiết Kiệm (GHTK) plug in alongside your own fleet for Hai Phong orders.
Deep integrations
ERP, PIM, WMS, CRM, POS, accounting and legacy systems with reliable, monitored data sync. Stock can be held in Hai Phong or anywhere in Vietnam, with pickup and local-delivery options where they make sense.
Migration
Move from older platforms with product, customer and order history, SEO-safe redirects and parallel runs. Reports show which products, customers and areas of Hai Phong drive revenue.
Performance and security
Caching, CDN, load testing, security hardening, audit logs and cloud infrastructure as code. Storefront language, imagery and navigation are set up for Hai Phong shoppers and available in Vietnamese.
Businesses that use NNT Mart in Hai Phong
Popular online categories in Vietnam include fashion, beauty, electronics, mother and baby, groceries and home. Local demand in Hai Phong is shaped by port and electronics manufacturing, so we often design catalogues and B2B ordering around those sectors. In Hai Phong, we most often build custom e-commerce platforms for:
Enterprises with complex catalogues
For enterprises with complex catalogues, we usually start with headless architecture, then add SAP, Oracle, Microsoft Dynamics and Odoo ERPs once orders are flowing.
Multi-brand groups
Catalogue, pricing and fulfilment rules designed for multi-brand groups in Hai Phong, connected to the systems you already use.
Businesses outgrowing SaaS platforms
Businesses outgrowing SaaS platforms get multi-entity operations plus migration workflows tailored to their operations.
Companies migrating legacy stores
We map how companies migrating legacy stores sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.
Regulated sectors
For regulated sectors, we usually start with performance and security, then add search engines (Elasticsearch, Algolia) once orders are flowing.
High-traffic retailers
Catalogue, pricing and fulfilment rules designed for high-traffic retailers in Hai Phong, connected to the systems you already use.
How Hai Phong customers pay online
Shoppers in Hai Phong rarely abandon a cart over price alone — they leave when their usual method is missing. Here that means cash on delivery, MoMo and ZaloPay, then VNPay QR, bank transfer (Napas 247) and Visa and Mastercard.
We integrate suitable gateways and providers for your business category and merchant eligibility, handle payment status, failed-payment retries and refunds, and keep sensitive card data with the provider rather than on your servers. All amounts are shown in Vietnamese đồng (VND).
Business buyers around the port often want invoices or bank transfer, while consumers lean on cash on delivery. We support both flows.
- Bank transfer (Napas 247)
- ZaloPay
- VNPay QR
- MoMo
- Visa and Mastercard
- Cash on delivery
Delivery and fulfilment from Hai Phong
Your custom e-commerce platform can book shipments and share tracking with Vietnam Post (VNPost), Giao Hàng Nhanh (GHN), Giao Hàng Tiết Kiệm (GHTK), Viettel Post, J&T Express and Ninja Van, or route orders to your own riders and stores across Hai Phong.
We set up shipping zones, cut-off times, free-shipping thresholds, cash-collection rules and returns so the promise on the product page matches what your team can deliver.
Connectivity in the area — Hai Phong port and Cat Bi Airport — makes regional and national dispatch from Hai Phong practical.
Hai Phong sellers: marketplace plus your own store
Shopee, TikTok Shop and Lazada are where many shoppers in Hai Phong start, which is why sellers list there. The trade-off is commission, limited branding and rules the platform can change overnight.
Your custom e-commerce platform becomes the hub: marketplaces and social shops become extra outlets fed from one catalogue, while repeat customers buy directly from you at better margins.
Rules Hai Phong sellers must respect online
Vietnam VAT is 10% standard, temporarily reduced to 8% for many goods, and e-commerce platforms withhold tax for household sellers from July 2025.
On privacy we design around Decree 13/2023 on Personal Data Protection and the Personal Data Protection Law taking effect in 2026; on consumer rights the store reflects the Law on Protection of Consumer Rights 2023 and Decree 85/2021 on e-commerce, which requires website notification to the MOIT.
Our job is the engineering: price display with tax, invoice numbering, cookie and marketing consent, return and terms pages, role-based access and logs. Legal and tax conclusions stay with your own adviser in Vietnam.
Mobile commerce in Hai Phong
Because the platform is API-first, customer, staff and partner mobile apps can be added at any point without rebuilding the backend.
Apps are published under your own developer accounts and share the same backend as your custom e-commerce platform, so offers, stock and orders are always consistent between web and mobile.
Order alerts, offers and abandoned-cart reminders go out on Hai Phong time (UTC+7), in Vietnamese if you want.
- BI and data warehouses
- Identity and SSO
- Cloud platforms (AWS, Azure, GCP)
- Search engines (Elasticsearch, Algolia)
- WMS and 3PL systems
- POS and store systems
- SAP, Oracle, Microsoft Dynamics and Odoo ERPs
- PIM and DAM
Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.
Launch roadmap and success metrics
Value first, depth later. For a custom e-commerce platform serving Hai Phong, the usual sequence looks like this:
| Phase | What goes live |
|---|---|
| Foundation | Architecture, core commerce, priority integrations and migration. Configured for VND, cash on delivery and Vietnam Post (VNPost) from the start. |
| Differentiate | Custom workflows, configurators and automation. |
| Optimise | Performance, new channels, apps and continuous enhancement. Reviewed against how Hai Phong customers actually buy. |
Success is measured on page load and API response times, uptime, order-sync accuracy, manual-work hours saved, release frequency and total cost of ownership — tracked on a dashboard you can see from launch day.
Working with our team from Hai Phong
Our team covers UTC+7 — 1h 30m ahead of India (IST) — through three 8-hour shifts, so a Hai Phong client always reaches someone during the local working day.
Project communication is in English; storefront content can be produced in Vietnamese. You get a named lead, direct engineer access and an NDA if you ask.
Our head office is in Chhapi, Gujarat, with an office in Hyderabad and representation in Nigeria, South Africa, Ethiopia and Zambia; Hai Phong clients are served remotely with on-site workshops when the project needs them.
