Saigon Technology designed and built VietMart, a multi-vendor online marketplace for Vietnam and Southeast Asia, built around one idea: the incumbents underdeliver on trust. Delivered as a fully interactive prototype spanning three roles, a buyer app, a seller dashboard, and a platform admin console, VietMart shows how escrow-backed orders, cash refunds, identity verification, and live, social shopping come together in a marketplace that’s fairer to sellers and safer for buyers than what they’re used to.
What The Client Required
Buyer AppÂ
- Discovery & search - browse by category, search with filters, and surface recommendations.Â
- Flash sales & promotions - time-boxed deals and vouchers that drive urgency and conversion.Â
- Product detail pages - images, descriptions, variations, and ratings & reviews.Â
- Cart & wishlist - save for later and check out when ready.Â
- Checkout & payments - voucher and discount application, with COD, e-wallet, and card options for local payment habits.Â
- Escrow-backed orders - payment held safely and released on delivery, so the buyer is protected end to end.Â
- Live map delivery tracking - follow an order's progress in real time, not just a status label.Â
- Livestream & social commerce - shop live, in the moment, inside the app.Â
- AI shopping assistant - guided, conversational help finding the right product.Â
- Orders & cash refunds - order history plus a returns flow that refunds real money, not vouchers.Â
Seller DashboardÂ
- Product management - add, edit, and delete listings; track inventory; bulk upload catalogs.Â
- Order & shipping management - confirm orders, manage fulfillment, and handle returns and refunds.Â
- Analytics - sales reports, product performance, and customer insights at a glance.Â
- Transparent fee calculator - shows a seller exactly how much they keep on each sale, turning fees from a surprise into a known number.Â
Admin ConsoleÂ
- Platform & GMV analytics - marketplace-wide visibility into volume and growth.Â
- VNeID verification review - approve and manage verified seller and buyer identities.Â
- Counterfeit & product moderation - keep fake and non-compliant listings off the platform.Â
- Promotion management - configure platform-wide campaigns and vouchers.Â
- Dispute resolution with SLA timer - resolve buyer–seller disputes against a visible clock, so nothing stalls.Â
Our Technologies
- Front end: React single-page applications (SPA) with client-side routing and role-based views.
- Applications by Platform & Role: A mobile-responsive buyer app and desktop seller / admin consoles.
- Experience: Themeable design system (adjustable brand, color, and VI / EN language), warm-neutral visual language, and responsive layouts.Â
- Localization: Bilingual Vietnamese / English; designed around local market needs including VNeID identity verification and local payment methods (COD / e-wallet / card).Â
Challenges
- Put trust at the core, not in the fine print - verified identities, money held safely until delivery, and real refunds, so buyers transact without second-guessing.Â
- Be fair to sellers - transparent fees that show exactly what a seller keeps, instead of margins that erode invisibly.Â
- Feel local - designed for the Vietnam and SEA market, with VNeID identity verification, local payment habits, and a bilingual Vietnamese / English experience.Â
- Make shopping social and live - livestreams and social commerce built into the product, not bolted on.Â
- Serve three audiences at once - buyers, sellers, and the platform's own operations team, each with a purpose-built surface.Â
- Prove the concept before heavy investment - a clickable, end-to-end experience stakeholders could walk through, not a slide deck.Â
Solutions
- The Buyer App (mobile) - discover, shop, watch live, pay safely, and track deliveries in real time.Â
- The Seller Dashboard (desktop) - manage products, orders, and analytics, with transparent take-home fees front and center.Â
- The Admin Console (desktop) - run the platform: GMV analytics, identity verification, counterfeit moderation, and time-bound dispute resolution.Â
- A central demo hub ties the three together, letting any stakeholder step into each role and see how the marketplace behaves end to end.Â
The OutcomeÂ
VietMart demonstrates, end to end and across three roles, what a trust-first marketplace looks like and how it behaves, a working, interactive product that stakeholders can click through rather than imagine.Â
What the build delivers: A complete buyer journey - from discovery and live shopping to escrow-protected checkout and real-time delivery tracking - in one polished, mobile-responsive experience. A seller experience that makes fees transparent and day-to-day operations (products, orders, analytics) self-service. An operations console that gives the platform team the levers that matter: verification, moderation, and time-bound dispute resolution. A brandable, localizable design system and a scalable React architecture ready for future phases.Â
Our Approach
MVP-first, design-led
We built VietMart as a fully interactive prototype so every role, screen, and flow could be experienced and validated, proving the trust-first thesis before committing to a full production build.
A cohesive, themeable design system
One visual language runs across all three surfaces: a warm coral brand color for energy, teal reserved for trust and verification signals, plus distinct accents for live commerce, AI, and flash sales, set in the Vietnamese-optimized "Be Vietnam Pro" typeface. The system is brandable out of the box: brand name, colors, and language (Vietnamese / English) are adjustable in each app's built-in "Tweaks" panel, so the platform adapts to an operator's brand and market.Â
Modern front-end engineering
VietMart is built as React single-page applications with role-based surfaces, a mobile-first buyer app alongside desktop seller and admin consoles, on a scalable foundation ready to grow into a full production marketplace.
Looking ahead (future phases)
VietMart's architecture is built to grow well beyond the prototype. Planned post-MVP enhancements include:Â
Logistics & delivery - third-party logistics (3PL) integrations, shipping-fee calculation, and an optional warehousing phase.Â
Growth & marketing - an affiliate program, plus push-notification and email campaigns.Â
Trust at scale - anti-spam review moderation and deeper fraud controls.Â
Deeper AI - expanding the AI assistant toward richer personalization and recommendations.Â
