The case for a B2B ordering portal in Chiang Mai

Chiang Mai is a commercial centre in Thailand where around 354,000 people live and shop, and one of the places where we build B2B and wholesale portals for local businesses.

Key sectors include digital nomads, tourism and startups, with business districts such as Nimman and the city centre.

Logistics are supported by Chiang Mai Airport, which matters when you promise customers fast delivery.

Thailand has one of the world's highest rates of social and chat commerce through LINE. Brands that move those conversations to a proper store with PromptPay checkout gain repeat customers.

That is why more companies in Chiang Mai are moving from phone, WhatsApp and spreadsheet orders to a proper B2B ordering portal — one place where products, prices, payments, orders and customers are managed together.

What makes a Chiang Mai store feel local

A store that works in Chiang Mai 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 Thai baht (THB), formatted the way Chiang Mai customers read them.

Language and content

Storefront copy, product pages and emails can run in Thai and English, with local date and number formats.

Local trust signals

We add the payment logos, courier names and policy pages shoppers in Chiang Mai recognise: PromptPay QR and TrueMoney Wallet and delivery through Thailand Post.

Domain, phone and contact

A .th domain (or your own) builds local trust and search relevance. Click-to-call and WhatsApp buttons use the +66 calling code so customers reach you without dialling errors.

Talent and partners nearby

With Chiang Mai University close by, finding people to manage catalogues, content and support after launch is realistic in Chiang Mai.

A B2B ordering portal built around your Chiang Mai business

Every NNT Mart B2B ordering portal in Chiang Mai is engineered to the client's own brief — the web platform, the admin panel and, when you need one, a mobile application built for your workflow.

Typical clients include FMCG distributors, industrial suppliers, electrical and hardware traders and medical and institutional suppliers. Categories that sell especially well online in Thailand — fashion, beauty and skincare, electronics and groceries — 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.

What your B2B ordering portal includes

Each module below is configured — or custom-developed — to your requirements. You choose what launches first and what follows in later phases.

Business accounts

Registration, KYC and approval, company hierarchies, branches, buyers and approvers with their own permissions. Couriers such as Thailand Post, Kerry Express (KEX) and Flash Express plug in alongside your own fleet for Chiang Mai orders.

Contract pricing

Price lists by customer, group or territory, quantity slabs, pack sizes, minimum order values and negotiated rates. Stock can be held in Chiang Mai or anywhere in Thailand, with pickup and local-delivery options where they make sense.

Quick and bulk ordering

SKU-code entry, spreadsheet upload, saved lists, re-order from history and scheduled repeat orders. Reports show which products, customers and areas of Chiang Mai drive revenue.

Quotes and approvals

Request-for-quotation, counter-offers, purchase-order upload and multi-level approval before submission. Storefront language, imagery and navigation are set up for Chiang Mai shoppers and available in Thai and English.

Credit and payments

Online payment, credit limits, pay-later terms, outstanding statements and payment reminders where approved. Product data imports from your existing sheets or ERP, so Chiang Mai teams do not re-type thousands of items.

Sales-team tools

Order on behalf of customers, territory assignment, visit notes and performance dashboards for representatives. Customers in Chiang Mai can pay with PromptPay QR, TrueMoney Wallet and Rabbit LINE Pay, with receipts and refunds handled in the same admin.

Industries in Chiang Mai we work with

Popular online categories in Thailand include fashion, beauty and skincare, electronics, groceries, home and health supplements. Local demand in Chiang Mai is shaped by digital nomads, tourism and startups, so we often design catalogues and B2B ordering around those sectors. In Chiang Mai, we most often build B2B and wholesale portals for:

Wholesalers

Catalogue, pricing and fulfilment rules designed for wholesalers in Chiang Mai, connected to the systems you already use.

FMCG distributors

FMCG distributors get contract pricing plus quotes and approvals workflows tailored to their operations.

Industrial suppliers

We map how industrial suppliers sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.

Electrical and hardware traders

For electrical and hardware traders, we usually start with credit and payments, then add warehouse and inventory systems once orders are flowing.

Medical and institutional suppliers

Catalogue, pricing and fulfilment rules designed for medical and institutional suppliers in Chiang Mai, connected to the systems you already use.

Dealer networks

Dealer networks get sales-team tools plus contract pricing workflows tailored to their operations.

Payments customers in Chiang Mai expect

A B2B ordering portal for Chiang Mai must support the way people here actually pay: PromptPay QR, TrueMoney Wallet, Rabbit LINE Pay, Visa and Mastercard, mobile banking apps and cash on delivery.

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 Thai baht (THB).

Zone-based payment rules let you offer different options for Nimman than for outer parts of Chiang Mai.

  • Cash on delivery
  • Rabbit LINE Pay
  • Mobile banking apps
  • Visa and Mastercard
  • PromptPay QR
  • TrueMoney Wallet

Fulfilment options for Chiang Mai orders

Your B2B ordering portal can book shipments and share tracking with Thailand Post, Kerry Express (KEX), Flash Express, J&T Express, Ninja Van and Lalamove, or route orders to your own riders and stores across Chiang Mai.

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 — Chiang Mai Airport — makes regional and national dispatch from Chiang Mai practical.

Your own store alongside Shopee and Lazada

Selling in Chiang Mai through Shopee, Lazada and TikTok Shop gets you reach quickly, yet the buyer belongs to the platform, not to you.

With your own B2B ordering portal you keep the customer data, set the offers and the packaging, and still push stock to marketplaces from a single admin.

Rules Chiang Mai sellers must respect online

Thai VAT is 7%, and foreign e-service providers must register under the e-Service VAT rules.

On privacy we design around the Personal Data Protection Act B.E. 2562 (PDPA), enforced by the PDPC since 2022; on consumer rights the store reflects the Consumer Protection Act and the Direct Sales and Direct Marketing Act, which require registration for online sellers.

Controls we implement include compliant invoices, consent capture, policy pages, restricted staff access and audit trails. Please confirm the final legal and tax position with a local adviser in Chiang Mai.

Mobile commerce in Chiang Mai

Phones carry most traffic in Thailand. A dealer and sales-representative app lets buyers re-order in seconds, scan products, check statements and receive scheme announcements, while reps take orders at the counter even with patchy connectivity.

Apps are published under your own developer accounts and share the same backend as your B2B ordering portal, so offers, stock and orders are always consistent between web and mobile.

Push notifications can be timed to UTC+7 so offers reach Chiang Mai customers when they are awake, and the interface can run in Thai and English.

  • WhatsApp and SMS notifications
  • Logistics and freight partners
  • Warehouse and inventory systems
  • ERP (SAP, Oracle, Microsoft Dynamics, Tally, Zoho)
  • BI and reporting tools
  • CRM and lead management
  • Accounting and e-invoicing
  • Credit and payment gateways

Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.

How we phase your B2B ordering portal

We launch the journeys that create value first, then add depth. A typical roadmap for a B2B ordering portal in Chiang Mai:

PhaseWhat goes live
Launch portalAccounts, contract pricing, catalogue, ordering and ERP order sync. Configured for THB, PromptPay QR and Thailand Post from the start.
AutomateQuotes, approvals, credit, statements and notifications.
ExpandDealer and sales-rep apps, analytics and new territories. Reviewed against how Chiang Mai customers actually buy.

Success is measured on order-entry time, share of orders placed online, order accuracy, days sales outstanding, repeat-order frequency and sales-rep productivity — tracked on a dashboard you can see from launch day.

How Chiang Mai clients work with us

Our team covers UTC+7 — 1h 30m ahead of India (IST) — through three 8-hour shifts, so a Chiang Mai client always reaches someone during the local working day.

We work in English and can deliver storefront content in Thai. NDAs are signed on request, and you get a named project lead plus direct access to the engineers building your B2B ordering portal.

Our head office is in Chhapi, Gujarat, with an office in Hyderabad and representation in Nigeria, South Africa, Ethiopia and Zambia; Chiang Mai clients are served remotely with on-site workshops when the project needs them.

You approve the working result before you pay

There is no standard price list, because every B2B ordering portal is quoted to your requirements and budget. What is standard is how you pay: a small advance, then milestones released only after written acceptance. An example:

Launch is where your B2B ordering portal starts earning — so we stay accountable

Every project includes a free 90-day defect warranty. After that, the same team that built your B2B ordering portal keeps it secure, updated and running on a fixed annual fee agreed up front — no open-ended hourly billing and no surprise invoices.

No lock-in: the platform is yours

For every B2B ordering portal, upon full and final payment the complete source code and intellectual property are transferred to you — so you can host, maintain and enhance the system with any developer.

Chiang Mai runs on UTC+7 (1h 30m ahead of India (IST)). We reply within 10 minutes around the clock, meet in your working hours and write storefront content in Thai and English as well as English.

Which couriers do you integrate for deliveries from Chiang Mai?

Cost depends on catalogue size, integrations, payment and delivery rules, mobile apps and support. Payments are split into milestones, and 90% is released only after you accept working modules.

Can you build a mobile app along with the B2B ordering portal for my Chiang Mai business?

Yes. We build Android and iOS apps for customers, dealers, delivery staff or administrators on the same backend as your B2B ordering portal, and publish them under your own Google Play and App Store accounts.
