Ecommerce Developer in Singapore

Hiring an ecommerce developer in Singapore usually ends in one of two disappointments: an agency that quotes five figures for what is essentially a template, or a freelancer who drops a theme on your domain and disappears. I'm Joshua — I run Outsourced SG, and I lead a small, vetted team of AI-trained developers who build custom storefronts, Shopify and WooCommerce stores, and product configurators for Singapore businesses. Think of me as the ecommerce developer Singapore SMEs call when a template stops being enough. Pricing starts at S$400/month per developer, most stores go live in under two weeks, and you own 100% of the code — no CPF, no foreign-worker levy, no lock-in.

Below I've laid out exactly what I build, how a custom build compares to a DIY Shopify, the real stores I've delivered (including WOYKE and Cocomadame.sg), the industries I work with, and the honest truth about EDG and PSG grants for e-commerce. No invented numbers, no fake testimonials — just what I actually do. If you'd rather talk it through, my WhatsApp button is on this page.

What a good ecommerce developer in Singapore actually does for you

Plenty of "developers" will drop a template on a domain and vanish. A proper e-commerce build is a system — storefront, catalogue, checkout, payments, delivery, tax and the admin tools you'll live in every day. Here's what my team covers end to end as your ecommerce development Singapore partner:

• Custom storefronts — fully bespoke online stores for when a template can't do what your brand or product needs (unusual catalogues, bundles, subscriptions, B2B pricing tiers).
• Shopify builds & theme customisation — as a Shopify developer Singapore merchants trust, I build clean, fast stores with custom sections, apps and Liquid tweaks, without the bloat that slows most themes down.
• WooCommerce on WordPress — flexible, self-owned stores for merchants who want content and commerce in one place; as a WooCommerce developer Singapore brands rely on, I keep you fully in control of your own store (like Cocomadame.sg).
• Product configurators — visual "build-your-own" tools so customers can see exactly what they're buying before they pay. This is product configurator development for Singapore's made-to-order brands (exactly what I built for WOYKE).
• Payment & logistics integrations — Stripe, PayNow/PayLah, credit cards, plus delivery and fulfilment hooks so orders flow without manual copying.
• Migrations & rescues — moving off a broken platform, un-slowing a heavy store, or taking over a build a previous freelancer abandoned.
• Automation & AI on top — order bots, stock alerts and a support AI chatbot that answers routine customer questions so you're not glued to your inbox.

Not sure whether you need a store, a broader web build, or a full application? I also do outsourced web development and custom software development — and I'll tell you honestly which one your project actually is before you spend a cent.

DIY Shopify vs a custom build — which do you actually need?

Let me save you an argument you're probably having with yourself. A DIY Shopify or Wix store is genuinely the right call for a lot of shops. If you sell 20 fairly standard products and a template layout works, spinning it up yourself is cheap and fast. You don't need me for that, and I'll say so.

You need a developer when the store has to do something the template can't: a configurator, complex bundles or subscriptions, B2B pricing, a custom checkout flow, deep integrations, or serious speed and SEO where every second of load time is costing you sales. Here's the honest comparison:

My rule of thumb: if a template does the job, use the template. Come to me when the template becomes the bottleneck — or when the store is core to your revenue and "good enough" isn't good enough.

Real e-commerce stores I've built and handed over

I won't quote you invented numbers or fake testimonials — that's a promise. But I'm happy to show you what I've actually delivered, and I hand every project over in person so you know it's real.

WOYKE — custom jewellery with a visual product configurator. WOYKE sells custom jewellery, so a normal "add to cart" was never going to work — customers needed to design their piece and see it before buying. I built a bespoke e-commerce store with a visual product configurator: shoppers build and preview their custom jewellery, then check out. It's a fully working store, delivered and handed over in person. If your product is made-to-order or personalised, this is the kind of build that turns "can you do X?" enquiries into clean, self-serve orders.

Cocomadame.sg — a WooCommerce fashion store. For Cocomadame's fashion label I built a full WooCommerce storefront on WordPress — catalogue, product pages, cart and checkout — a real, working store the owner controls. WooCommerce was the right pick here because it keeps content and commerce in one place and leaves the merchant fully in charge.

And more. I've also built order and purchase automation (like the Susy & Bae auto-purchase bot) and a customer-service AI chatbot for Vroom Garage, delivered in milestones. Across the business, that's 60+ websites, apps, e-commerce stores and automation projects handed over since 2019. You can see how the wider process works in my guide to outsourcing software development in Singapore.

Industries I build e-commerce for

E-commerce isn't one thing. A jewellery configurator, a fashion boutique, and a workshop taking bookings all need different plumbing. These are the industries I most often build for in Singapore:

• Fashion & apparel — lookbook-style storefronts, variants, sizing, and fast mobile checkout (like Cocomadame.sg).
• Jewellery & custom/made-to-order goods — visual configurators and "design-your-own" flows (like WOYKE).
• Food, F&B & grocery — ordering, delivery slots, and menu/catalogue management.
• Health, beauty & wellness — subscriptions, bundles, and repeat-order flows.
• Automotive & workshops — parts stores, plus booking and customer-service automation.
• Home, lifestyle & retail brands — clean catalogues with strong brand design.
• B2B & wholesale — tiered pricing, minimum-order quantities, quote requests, and account logins.

If your niche isn't on the list, message me anyway — the underlying build (catalogue, checkout, payments, admin) is the same skeleton, and the specialised parts are exactly what a custom developer is for.

Speed and SEO: a slow store is a leaky bucket

An e-commerce store lives or dies on two numbers most template shops ignore: how fast it loads and whether Google can read it. Every extra second of load time quietly costs you carts, and a store that isn't structured for search leaves you paying for ads to plug the gap. So I build with that in mind from day one — clean, semantic markup, image optimisation, lazy loading, Core Web Vitals awareness, proper product schema, and correct metadata so a custom online store Singapore shoppers find in search can actually rank and appear in Google Shopping. That's ecommerce web development Singapore founders can grow on, not just launch.

Because my team works with AI-accelerated tooling, we ship this faster than a traditional agency without cutting the fundamentals. That speed is also why most stores go live in under two weeks, and urgent jobs in 3–5 days.

Payments, logistics and the integrations that matter in Singapore

A store that can't take money smoothly isn't a store. I wire up the payment and fulfilment stack Singapore shoppers actually expect:

• Payments — Stripe, credit/debit cards, PayNow and PayLah, and buy-now-pay-later where it fits.
• Delivery & logistics — shipping rates, delivery-slot booking, and hooks into courier/fulfilment partners.
• Back-office — inventory sync, order notifications, invoicing, and exports into your accounting or ERP.
• Marketing — email/abandoned-cart flows, analytics, and pixel setup so you can see what's working.

If part of your workflow is still manual — copying orders into a spreadsheet, chasing stock, replying to the same customer questions — that's exactly what I automate, so the store handles the busywork instead of you.

How your store gets built, step by step

You won't be left guessing what's happening. I keep the process short, visible and milestone-based so you always know where your money's going:

1. Free scoping chat — you tell me what you sell and what the store must do; I turn it into clear milestones and an honest quote, no charge.
2. Design & build — a vetted, dedicated developer builds your storefront while you review progress weekly and steer as we go.
3. Integrations & testing — payments, delivery and admin get wired up and tested with real test orders before anything goes live.
4. Launch & in-person handover — the store goes live, and I hand it over — code, admin access, and a walkthrough so you can run it yourself.

After handover the store is fully yours: 100% IP assignment means the code, content and domain stay with you, with nothing locked behind me. Most clients keep a developer on to add features, run promotions and handle seasonal spikes, but you're never obliged to — there's no lock-in, and you can pause or stop whenever you like.

Ecommerce developer Singapore pricing (and why I'm cheaper than an agency)

Local e-commerce agencies routinely quote S$8,000–50,000 for a store. My developers start at S$400/month each (Starter Squad, 1–2 devs) and S$550/month each (Product Team, 3–5 devs) — SGD, one flat invoice, and most stores ship inside the first month or two. Full numbers are on the pricing section.

I'm cheaper for structural reasons, not because the work is worse. My developers are based in Indonesia (GMT+7, just one hour behind Singapore), so there's no CPF and no foreign-worker levy — that alone saves roughly 17–37% versus a comparable local hire, where a mid-level developer runs about S$6,000–12,000 a month fully loaded. There's no agency overhead stacked on top, and no lock-in. You get a Singapore point of contact (me), a vetted full-time developer, and a 30-day replacement guarantee if the fit's wrong. For a fuller cost picture, see what it costs to build an MVP in Singapore and how to vet offshore developers so you know what "cheap" should and shouldn't mean.

EDG and PSG grants for e-commerce — the honest version

People ask me constantly whether a grant will cover their store, so here's the straight answer. A qualifying custom-software project may be supportable under the Enterprise Development Grant (EDG) — typically up to around 50% of qualifying costs, subject to eligibility and approval. A bespoke storefront can sometimes be scoped to fit there, and I'm happy to help you check.

The Productivity Solutions Grant (PSG) is different: it funds pre-approved packaged solutions, not bespoke development. So a fully custom store I build for you generally won't be PSG-claimable — if you specifically want a PSG-supported route, that means adopting a pre-approved packaged e-commerce solution, which is a different product from what I do. I'd rather tell you that upfront than pretend my core service is "PSG-eligible" when it isn't.

This isn't grant or legal advice — grant rules and lists change, so confirm current eligibility with Enterprise Singapore before you budget around it. For a fuller breakdown, read my guide to EDG and PSG grants for software development in Singapore.

That's the whole picture — what I build, what it costs, and where I'll happily tell you to use a template instead. If you've got a store to build, fix or rescue, send me a message and I'll give you an honest scope and quote, no charge.

Frequently asked questions

Why are you cheaper than a Singapore ecommerce agency?

Structural reasons, not corner-cutting. My developers are full-time and based in Indonesia (GMT+7, one hour behind Singapore), so there's no CPF and no foreign-worker levy — that saves roughly 17–37% versus a comparable local hire, where a mid-level developer runs about S$6,000–12,000 a month fully loaded. There's no agency markup stacked on top and no lock-in, and you still get a Singapore point of contact — me. Pricing starts at S$400/month per developer.

Can I use EDG or PSG grants for my online store?

Possibly EDG, generally not PSG. A qualifying custom-software project may be supportable under the Enterprise Development Grant (EDG), typically up to around 50% of qualifying costs, subject to eligibility and approval. The Productivity Solutions Grant (PSG) funds pre-approved packaged solutions, not bespoke development, so a fully custom store I build usually isn't PSG-claimable. I'll help you check and scope it — but this isn't grant or legal advice, so confirm current eligibility with Enterprise Singapore.

What happens after you hand over the store?

The store is 100% yours. You get all the code, admin access and the domain, plus a walkthrough so you can run it. There's no lock-in — you can manage it yourself, bring in another developer, or keep one of mine on to add features and handle busy seasons. It's your choice, always.

Do you sign an NDA, and is my data handled under PDPA?

Yes. I sign an NDA before we get into sensitive details, and you get 100% IP assignment on everything built. Data is handled in line with Singapore's PDPA. If you have your own data-processing agreement or security requirements, I'm happy to work to them.

Shopify or WooCommerce — which is right for me?

It depends on your needs. Shopify is fastest to launch and lowest-maintenance if a hosted platform suits you. WooCommerce on WordPress is best if you want content and commerce together and full control of your own store, like I built for Cocomadame.sg. If neither fits — say you need a configurator or unusual logic — a custom build is the answer. I'll recommend the honest option for your case, not the one that bills the most.

Can you build a custom product configurator?

Yes. A visual product configurator is exactly what I built for WOYKE's custom jewellery — customers design and preview their piece before checkout. If your product is made-to-order, personalised or bundled, I can build a configurator that turns complex orders into a clean, self-serve flow.

Can you integrate PayNow, Stripe and local delivery couriers?

Yes. I set up Stripe, credit and debit cards, PayNow and PayLah, plus shipping rates, delivery-slot booking and hooks into courier and fulfilment partners. I can also connect inventory, invoicing and your accounting or ERP so orders don't get re-typed by hand.

How long does it take to build an online store?

Most stores go live in under two weeks, and urgent builds in 3–5 days. Larger custom stores with configurators or deep integrations take longer — I'll give you a milestone timeline in the free scoping chat so there are no surprises.

Can you fix, speed up or take over my existing store?

Yes — rescues and migrations are common work. Whether it's a slow store, a broken checkout, a platform migration or a build a previous freelancer abandoned, I'll audit what you have and scope the fix before you commit to anything.

Will my store be fast and SEO-friendly?

Yes — it's built in from day one: clean semantic markup, optimised images, lazy loading, Core Web Vitals awareness, product schema and correct metadata so your products can appear in search and Google Shopping. A fast, well-structured store converts better and leans less on paid ads.

Can you add an AI chatbot or automation to my store later?

Yes, and it's a popular add-on. I can bolt order and stock automation, or a customer-service AI chatbot like the one I built for Vroom Garage, onto an existing store — so routine enquiries and manual tasks handle themselves.
