Quick answer

Who builds an online store in Singapore?

NNT Mart by N&T Software builds custom online stores and mobile apps for businesses in Singapore, designed to each client's requirements. Platforms support PayNow QR, Visa and Mastercard and GrabPay, ship through SingPost and Ninja Van, follow the Personal Data Protection Act 2012 (PDPA), and come with a free demo within 24 hours of the requirements meeting.

Key takeaways

  • Singapore businesses tell us what they sell and how they want to sell it; our engineers turn that into a custom online store, an admin system and a mobile app shaped around their operations.
  • Checkout ready for PayNow QR, Visa and Mastercard and GrabPay, with delivery through SingPost and Ninja Van or your own team.
  • GST-ready invoicing and controls designed around the Personal Data Protection Act 2012 (PDPA).
  • Free demo within 24 hours of the requirements meeting; you own 100% of the source code after final payment.

Why Singapore businesses are investing in online stores

Singapore is a market of about 5.9 million people where online stores are growing fast, with Singapore as its capital.

Singapore is the regional HQ hub for Southeast Asian commerce, with near-universal mobile payments and very fast delivery. Many brands launch here before expanding across ASEAN.

For a business in Singapore, the opportunity is to own the customer relationship: your own online store keeps your margin, your data and your brand, while marketplaces and social channels become additional sales routes instead of the only one.

What makes a Singapore store feel local

Conversion in Singapore depends on small local signals — the right currency, the right words and the right payment and courier names.

Currency and pricing

The store speaks Singapore dollar: SGD amounts from product page to invoice, so Singapore buyers never convert in their heads.

Language and content

Content can be produced in English, Mandarin and Malay, so a Singapore customer reads the store in the language they use at home.

Local trust signals

Badges for PayNow QR and Visa and Mastercard, SingPost delivery and clear return terms reassure first-time buyers in Singapore.

Domain, phone and contact

Using .sg where it suits you signals a local business to shoppers and search engines. Click-to-call and WhatsApp buttons use the +65 calling code so customers reach you without dialling errors.

Designed to your requirements, not a template

Whatever your business sells in Singapore, N&T Software designs and develops the online store and the matching mobile app exactly to your requirements — your catalogue, your prices, your payment and delivery rules.

Typical clients include D2C start-ups, speciality shops, manufacturers selling direct and grocery and food businesses. Categories that sell especially well online in Singapore — electronics, fashion, groceries and beauty — get catalogue structures and filters designed for them.

Before any commitment you get a free requirements meeting, a demo built on your use case and a proposal priced to your budget.

Core modules we build for Singapore clients

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

Branded storefront

A fast, mobile-first design on your own domain with your colours, typography, banners, landing pages and SEO-ready category structure. Storefront language, imagery and navigation are set up for Singapore shoppers and available in English and Mandarin.

Catalogue manager

Categories, brands, variants, bundles, specifications, images, videos and bulk import/export so your team can manage thousands of SKUs. Product data imports from your existing sheets or ERP, so Singapore teams do not re-type thousands of items.

Checkout and payments

Guest and account checkout, local payment gateways, wallets, bank transfer, cash on delivery, coupons and abandoned-cart recovery. Checkout is configured for PayNow QR, Visa and Mastercard and GrabPay.

Orders and fulfilment

Order confirmation, packing slips, courier booking, tracking links, cancellations, returns, refunds and customer notifications. Couriers such as SingPost, Ninja Van and J&T Express plug in alongside your own fleet for Singapore orders.

Inventory and locations

Stock by warehouse or store, low-stock alerts, store pickup, local delivery zones and sync with your existing inventory system. Multiple stock points in Singapore are supported, so a Singapore order ships from the nearest one.

Growth and reporting

Promotions, loyalty, reviews, email and WhatsApp campaigns, plus dashboards for revenue, products, customers and conversion. Reports show which products, customers and areas of Singapore drive revenue.

How Singapore customers pay online

Shoppers in Singapore rarely abandon a cart over price alone — they leave when their usual method is missing. Here that means PayNow QR, Visa and Mastercard and GrabPay, then Apple Pay and Google Pay, Atome BNPL and NETS.

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 Singapore dollar (SGD).

  • GrabPay
  • NETS
  • Visa and Mastercard
  • Apple Pay and Google Pay
  • PayNow QR
  • Atome BNPL

Shipping, couriers and local delivery in Singapore

Your online store can book shipments and share tracking with SingPost, Ninja Van, J&T Express, Lalamove, Qxpress and POPStation lockers, or route orders to your own riders and stores.

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.

Selling online legally in Singapore

For Singapore sellers, tax first: Singapore GST is 9% (since January 2024) and overseas vendors selling low-value goods to Singapore consumers must register under the OVR regime.

On privacy we design around the Personal Data Protection Act 2012 (PDPA), enforced by the PDPC, including the Do Not Call registry; on consumer rights the store reflects the Consumer Protection (Fair Trading) Act, which prohibits misleading claims and drip pricing.

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.

Your own store alongside Shopee and Lazada

Shopee, Lazada and Amazon.sg are where many shoppers in Singapore start, which is why sellers list there. The trade-off is commission, limited branding and rules the platform can change overnight.

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

Industries in Singapore we work with

Popular online categories in Singapore include electronics, fashion, groceries, beauty, health supplements and home. In Singapore, we most often build online stores for:

Retail brands

Retail brands get branded storefront plus checkout and payments 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.

Speciality shops

For speciality shops, we usually start with orders and fulfilment, then add accounting and GST/VAT invoicing once orders are flowing.

Manufacturers selling direct

Catalogue, pricing and fulfilment rules designed for manufacturers selling direct in Singapore, connected to the systems you already use.

Grocery and food businesses

Grocery and food businesses get inventory and locations plus branded storefront workflows tailored to their operations.

Multi-outlet retailers

We map how multi-outlet retailers sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.

Mobile commerce in Singapore

A customer shopping app for Android and iOS can share the same catalogue, cart, offers and order history, with push notifications for drops, price alerts and delivery updates.

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

Order alerts, offers and abandoned-cart reminders go out on Singapore time (UTC+8), in English and Mandarin if you want.

  • Accounting and GST/VAT invoicing
  • ERP and inventory software
  • WhatsApp Business API
  • Payment gateways and wallets
  • Courier and shipping aggregators
  • CRM and email marketing
  • Meta and TikTok catalogues
  • Google Analytics 4 and Merchant Center

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 online store

We launch the journeys that create value first, then add depth. A typical roadmap for an online store in Singapore:

PhaseWhat goes live
Launch storeStorefront, catalogue, checkout, payments, shipping and admin go live. Configured for SGD, PayNow QR and SingPost from the start.
GrowPromotions, loyalty, reviews, marketing integrations and SEO content.
ScaleMobile app, marketplace feeds, multi-warehouse and ERP sync. Reviewed against how Singapore customers actually buy.

We track conversion rate, average order value, cart abandonment, repeat-purchase rate, page speed (Core Web Vitals) and return rate on a live dashboard from day one, so Singapore results are visible, not promised.

How Singapore clients work with us

Singapore runs on UTC+8, which is 2h 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.

We work in English and can deliver storefront content in Standard Chinese, Malay and Tamil. NDAs are signed on request, and you get a named project lead plus direct access to the engineers building your online store.

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

How we work

How we deliver your online store in Singapore

We do not sell a fixed template. Each online store for businesses in Singapore moves through seven gated stages, and nothing advances — and nothing is invoiced — until you have approved the working result.

You approve the working result before you pay

Milestones are customised to your requirements — six or more is typical, and delivery time is agreed around your scope. Every payment after the advance is released only after you have seen the working result and given written sign-off. Here is an example plan for a online store:

Launch is where your online store starts earning — so we stay accountable

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

100% of the source code and IP is owned by you

For every online store, 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.
