Selling online sounds simple until you start pricing it. One shop owner sets up Shopify in a weekend for the cost of a monthly subscription. Another spends $15,000 on a custom platform. Both are running "an e-commerce website", which tells you how wide the range really is.
The right choice depends on what you sell, how many products you carry, and how much you want to manage yourself. A home baker selling ten items has very different needs from a retailer with 2,000 stock-keeping units and a warehouse to sync.
This guide breaks down ecommerce website cost in Singapore for 2026 across the three main routes: WooCommerce, Shopify and a custom build. We will cover the upfront cost, the ongoing fees that catch people out, and which one fits which kind of shop.
What drives ecommerce website cost in Singapore
An online shop costs more than a brochure site because it does more. It takes money, syncs stock, sends order emails and has to stay secure. Here is what moves the price.
Number of products
Ten products is a quick setup. Two thousand products, with variants, photos and stock counts, is a serious data and design job. More products means more build time and often a higher monthly tier.
Payment and delivery setup
You will need a way to take payment and a way to handle delivery. In Singapore that often means connecting a local payment gateway and a courier or delivery option. Each connection is setup work, and some carry their own fees.
Platform choice
This is the big fork. Shopify is a paid monthly service that does a lot for you. WooCommerce is software you add to a WordPress site, cheaper monthly but more to manage. Custom is built from scratch, most flexible and most expensive.
Design and trust
People hand over card details on your site, so it has to look trustworthy. A polished, mobile-friendly design is not vanity for a shop, it directly affects whether someone completes checkout or bails.
WooCommerce vs Shopify vs custom: the comparison table
Here is the head-to-head. These are typical 2026 SGD ranges for a small to mid Singapore shop. Treat them as estimates, since product count and features swing the numbers.
| Factor | WooCommerce | Shopify | Custom build |
|---|---|---|---|
| Typical upfront build (SGD) | $1,500 to $6,000 | $1,000 to $5,000 | $10,000 to $40,000+ |
| Ongoing platform cost | Hosting ~$20 to $80/mo plus some paid plugins | ~$39 to $150+/mo subscription | Hosting and upkeep, often higher |
| Transaction fees | Only your payment gateway's fees | Subscription plus gateway fees (extra fee if not using Shopify Payments) | Only your gateway's fees |
| Ease of running it yourself | Moderate, more moving parts | Easiest, built to be self-managed | Depends entirely on the build |
| Flexibility | High, open and customisable | Medium, within Shopify's system | Highest, anything is possible |
| Best for | Owners wanting control and lower monthly fees | Owners wanting fast, low-fuss selling | Large catalogues or unusual requirements |
| Main catch | You own the maintenance burden | Monthly fees and less control add up | Expensive and slow to build |
Which one is right for your shop?
The platform should match the shop, not the other way round. Here is a plain guide to which route tends to suit which seller.
Choose Shopify if
- You want to start selling quickly with minimal fuss.
- You are comfortable with a monthly fee in exchange for someone else handling the technical side.
- Your catalogue is small to medium and fairly standard.
Choose WooCommerce if
- You already have or want a WordPress site and a blog.
- You want lower monthly costs and more control over how things work.
- You are okay with a bit more responsibility for updates and upkeep, ideally with a care plan.
Choose a custom build if
- You have a large or unusual catalogue that off-the-shelf tools handle badly.
- You need something specific that neither platform does well.
- You have the budget and the volume to justify it. Most small shops do not, and that is fine.
For most Singapore SMEs starting out, Shopify or WooCommerce covers the job at a fraction of custom cost. Jumping straight to custom is one of the most common ways to overspend.
The ongoing costs people forget
The build price is only half the story. An online shop has running costs that a simple brochure site does not. Budget for these from the start.
- Payment gateway fees. Expect a percentage plus a small flat fee on each sale. This is normal and unavoidable across every platform.
- Platform or hosting. Shopify's subscription, or WooCommerce hosting plus the odd paid plugin.
- Maintenance. A shop must stay secure and updated, more so than a brochure site, because it handles money. See our guide to website maintenance cost in Singapore.
- Apps and add-ons. Reviews, email, loyalty and so on. Useful, but they stack up monthly, so add only what earns its keep.

Frequently asked questions
What is the cheapest way to start selling online in Singapore?
For very small catalogues, a basic Shopify plan or a simple WooCommerce setup is usually the cheapest sensible route, with build costs from around $1,000 to $1,500 plus ongoing fees. Avoid jumping to a custom platform, which is far pricier and rarely needed at the start.
Do I have to pay fees on every sale?
Yes. Every platform involves payment gateway fees, typically a small percentage plus a flat amount per transaction. Shopify may add its own fee on top if you do not use its in-house payment system. Factor these into your pricing from day one.
Can I move from Shopify to WooCommerce later, or the other way?
You can, but it is a migration project with real effort, especially with many products and orders. It is better to choose the right platform up front based on your catalogue size and how much you want to self-manage, rather than planning to switch later.
