Why a multi-vendor marketplace makes sense for Hai Phong
Hai Phong is a centrally-governed city of vietnam, home to about 2.1 million people, and one of the markets in Vietnam where we build multi-vendor marketplaces.
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 multi-vendor marketplace — one place where products, prices, payments, orders and customers are managed together.
Local details we build into every Hai Phong project
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
Everything a Hai Phong shopper sees — price, tax, delivery fee, refund — is in VND, written the local way.
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
Badges for cash on delivery and MoMo, Vietnam Post (VNPost) delivery and clear return terms reassure first-time buyers in Hai Phong.
Domain, phone and contact
A .vn domain (or your own) builds local trust and search relevance. Click-to-call and WhatsApp buttons use the +84 calling code so customers reach you without dialling errors.
Talent and partners nearby
With Hai Phong University close by, finding people to manage catalogues, content and support after launch is realistic in Hai Phong.
Custom-built for how you sell in Hai Phong
We do not hand Hai Phong businesses a ready-made theme: we study how you sell, then build the online platform and Android/iOS app your customers and staff actually need.
In Hai Phong we typically work with industry-specific marketplaces, regional seller networks, B2B supplier platforms and service-provider marketplaces, and with sellers in categories such as fashion, beauty, electronics and mother and baby that have strong online demand in Vietnam.
Before any commitment you get a free requirements meeting, a demo built on your use case and a proposal priced to your budget.
What your multi-vendor marketplace includes
Each module below is configured — or custom-developed — to your requirements. You choose what launches first and what follows in later phases.
Vendor onboarding
Application, document verification, agreements, approval and seller dashboards with team access. Bulk import and sync tools mean the Hai Phong team never re-keys stock, prices or descriptions by hand.
Catalogue governance
Listing templates, moderation queues, category rules, image standards and duplicate detection. Customers in Hai Phong can pay with cash on delivery, MoMo and ZaloPay, with receipts and refunds handled in the same admin.
Commission engine
Commissions and fees by vendor, category, product or transaction, with promotions funded by either party. 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.
Order routing
Split carts, vendor-wise fulfilment, shipping rules, service areas and delivery tracking. Stock can be held in Hai Phong or anywhere in Vietnam, with pickup and local-delivery options where they make sense.
Settlements
Payout calculations, reconciliation reports and integration with split-payment providers where permitted. Revenue reports by product, repeat buyer and delivery area of Hai Phong guide stock and marketing decisions.
Trust and support
Ratings, reviews, returns, disputes, seller performance scores and customer-support workflows. Content and design can follow how customers in Hai Phong search and buy, including Vietnamese where you need it.
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 multi-vendor marketplaces for:
Industry-specific marketplaces
We map how industry-specific marketplaces sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.
Regional seller networks
For regional seller networks, we usually start with commission engine, then add KYC and business verification once orders are flowing.
B2B supplier platforms
Catalogue, pricing and fulfilment rules designed for B2B supplier platforms in Hai Phong, connected to the systems you already use.
Service-provider marketplaces
Service-provider marketplaces get order routing plus trust and support workflows tailored to their operations.
Institutional procurement platforms
We map how institutional procurement platforms sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.
Artisan and curated brand marketplaces
For artisan and curated brand marketplaces, we usually start with vendor onboarding, then add CRM and helpdesk once orders are flowing.
Getting paid online in Hai Phong
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.
Gateway selection depends on your category and merchant approval; we connect the provider, reconcile payments, automate retries and refunds, and never store raw card data. Prices, taxes and refunds appear in Vietnamese đồng (VND).
For Hai Phong customers ordering from the port and industrial zones, cash-on-delivery and pay-on-pickup rules can be set per delivery zone.
- ZaloPay
- Bank transfer (Napas 247)
- Visa and Mastercard
- MoMo
- Cash on delivery
- VNPay QR
Fulfilment options for Hai Phong orders
Your multi-vendor marketplace 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.
Delivery rules can price by distance, weight, postcode or zone, offer same-day slots in dense areas, and switch on pickup points or click-and-collect where customers prefer them.
Connectivity in the area — Hai Phong port and Cat Bi Airport — makes regional and national dispatch from Hai Phong practical.
Marketplaces vs. your own multi-vendor marketplace 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.
With your own multi-vendor marketplace you keep the customer data, set the offers and the packaging, and still push stock to marketplaces from a single admin.
Rules Hai Phong sellers must respect online
Tax basics: Vietnam VAT is 10% standard, temporarily reduced to 8% for many goods, and e-commerce platforms withhold tax for household sellers from July 2025.
Customer data is handled with Decree 13/2023 on Personal Data Protection and the Personal Data Protection Law taking effect in 2026 in mind, and the storefront follows 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.
Mobile commerce in Hai Phong
Phones carry most traffic in Vietnam. Separate buyer and seller apps let customers shop and track orders while vendors manage listings, accept orders and see payouts from their phones.
Apps are published under your own developer accounts and share the same backend as your multi-vendor marketplace, 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.
- KYC and business verification
- WhatsApp and push notifications
- Analytics and BI
- Tax and invoicing systems
- Logistics aggregators
- Split-payment and escrow providers
- CRM and helpdesk
- Search and recommendation engines
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
We launch the journeys that create value first, then add depth. A typical roadmap for a multi-vendor marketplace in Hai Phong:
| Phase | What goes live |
|---|---|
| Pilot marketplace | Seller onboarding, catalogue, checkout, order routing and basic payouts. Configured for VND, cash on delivery and Vietnam Post (VNPost) from the start. |
| Govern and grow | Moderation, commissions, promotions, reviews and dispute handling. |
| Scale | Buyer and seller apps, new categories, cities and service areas. Reviewed against how Hai Phong customers actually buy. |
Success is measured on active sellers, GMV and take rate, listing approval time, order defect rate, seller payout accuracy and buyer repeat rate — tracked on a dashboard you can see from launch day.
Time zones, language and support
Hai Phong runs on UTC+7, which is 1h 30m ahead of India (IST). With three 8-hour shifts we are available 24×7, so meetings, demos and urgent fixes happen in your working hours.
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.
