Why a shopping app makes sense for 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 mobile commerce apps.
Key sectors include port and electronics manufacturing, with business districts such as 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.
That is why more companies in Hai Phong are moving from phone, WhatsApp and spreadsheet orders to a proper shopping app — one place where products, prices, payments, orders and customers are managed together.
Localised for Hai Phong, not translated into it
Conversion in Hai Phong depends on small local signals — the right currency, the right words and the right payment and courier names.
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
We localise pages, emails and notifications into Vietnamese where your audience needs it.
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
Using .vn where it suits you signals a local business to shoppers and search engines. Click-to-call and WhatsApp buttons use the +84 calling code so customers reach you without dialling errors.
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.
Designed to your requirements, not a template
If you run a business in Hai Phong and want to sell online, we build an e-commerce platform and mobile application to your exact requirements, from the first product page to the last delivery update.
Typical clients include grocery and pharmacy chains, restaurants and cloud kitchens, distributors with dealer networks and D2C start-ups. 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.
Features of your shopping app in Hai Phong
These are the building blocks of a shopping app. We scope them with you, so you pay for what your Hai Phong operation needs.
Customer shopping app
Browse, search, wish-lists, cart, wallet and UPI or card checkout, order tracking and push offers. Reports show which products, customers and areas of Hai Phong drive revenue.
Dealer and B2B app
Account pricing, quick re-order, statements, schemes and barcode scanning for trade buyers. Content and design can follow how customers in Hai Phong search and buy, including Vietnamese where you need it.
Delivery partner app
Assigned orders, route navigation, proof of delivery, COD collection and status updates. Bulk import and sync tools mean the Hai Phong team never re-keys stock, prices or descriptions by hand.
Store and admin app
Order alerts, stock updates, price changes and sales snapshots for owners and managers. Customers in Hai Phong can pay with cash on delivery, MoMo and ZaloPay, with receipts and refunds handled in the same admin.
Engagement
Segmented push notifications, deep links, in-app banners, loyalty and referral programmes. 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.
Performance and offline
Fast native-feel UI, image caching, offline cart and graceful handling of poor networks. Inventory can sit in Hai Phong, in a partner warehouse or across Vietnam, with click-and-collect where customers want it.
Industries in Hai Phong we work with
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 mobile commerce apps for:
Retail brands
We map how retail brands sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.
Grocery and pharmacy chains
For grocery and pharmacy chains, we usually start with delivery partner app, then add payment SDKs and wallets once orders are flowing.
Restaurants and cloud kitchens
Catalogue, pricing and fulfilment rules designed for restaurants and cloud kitchens in Hai Phong, connected to the systems you already use.
Distributors with dealer networks
Distributors with dealer networks get store and admin app plus performance and offline workflows tailored to their operations.
D2C start-ups
We map how D2C start-ups sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.
Marketplace operators
For marketplace operators, we usually start with customer shopping app, then add barcode and QR scanning once orders are flowing.
How Hai Phong customers pay online
Checkout is where most online sales are won or lost. In Vietnam, customers expect to pay with cash on delivery, MoMo and ZaloPay, and many also look for 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.
- ZaloPay
- Visa and Mastercard
- MoMo
- VNPay QR
- Bank transfer (Napas 247)
- Cash on delivery
Fulfilment options for Hai Phong orders
Your shopping app 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.
Marketplaces vs. your own shopping app in Hai Phong
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.
NNT Mart gives you a channel you own: your domain, your customer list, your pricing and your brand. Where it helps, we connect product feeds and orders from marketplaces so stock stays in sync and your team works from one dashboard.
Tax, invoicing and compliance in Vietnam
On tax: Vietnam VAT is 10% standard, temporarily reduced to 8% for many goods, and e-commerce platforms withhold tax for household sellers from July 2025.
Two frameworks shape the build: Decree 13/2023 on Personal Data Protection and the Personal Data Protection Law taking effect in 2026, and the Law on Protection of Consumer Rights 2023 and Decree 85/2021 on e-commerce, which requires website notification to the MOIT.
We build the technical controls — tax-inclusive pricing, compliant invoices, consent banners, terms and return pages, data-access roles and audit logs. We are not a law firm, so final legal and tax positions should be confirmed with your own adviser in Vietnam.
Take your Hai Phong store onto customers' phones
Every app is published under your own Google Play and Apple developer accounts, with crash reporting, analytics and release management included.
One backend serves the website and the apps, and the apps ship under your own Google Play and App Store accounts — so what you change once appears everywhere.
Push notifications can be timed to UTC+7 so offers reach Hai Phong customers when they are awake, and the interface can run in Vietnamese.
- Commerce APIs and headless backends
- Firebase and push messaging
- Barcode and QR scanning
- Customer support chat
- Social login
- Analytics and crash reporting
- Payment SDKs and wallets
- Maps and location services
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 shopping app serving Hai Phong, the usual sequence looks like this:
| Phase | What goes live |
|---|---|
| MVP app | Core shopping, checkout, order tracking and push notifications. Configured for VND, cash on delivery and Vietnam Post (VNPost) from the start. |
| Engage | Loyalty, referrals, personalised offers and deep links. |
| Extend | Dealer, delivery and admin apps on the same backend. Reviewed against how Hai Phong customers actually buy. |
We track app installs and active users, app conversion rate, push-notification click rate, crash-free sessions, store rating and share of revenue from app on a live dashboard from day one, so Hai Phong results are visible, not promised.
