What affects ecommerce website development cost
Six factors account for most of the variation in ecommerce website development cost in Singapore. Understanding each one helps founders make informed decisions before committing to a build.
Platform choice
Platform choice is one of the most significant decisions, as it determines the cost structure across development, hosting, maintenance, and future scalability. There are three main options: Shopify, WooCommerce, and a fully custom build.
Shopify is a fully hosted platform that handles server infrastructure, security, and software updates as part of the monthly subscription. WooCommerce is open-source ecommerce software installed on a WordPress site, with lower monthly costs but more technical maintenance responsibility on the business. A fully custom build is developed from scratch on proprietary technology, offering complete control over every aspect of the store but at significantly higher upfront and ongoing cost.
While Shopify and WooCommerce are the most widely used ecommerce platforms in Singapore, other similar options exist, including BigCommerce, Wix, and Squarespace. Each has its own pricing model and feature set. The right choice depends on the business's size, technical resources, and growth requirements.
Product catalogue size and structure
Catalogue size and structure directly affect how much work goes into setting up and configuring the store. A small catalogue of 20 to 30 products can often be uploaded and managed by the founder directly through the platform's content management system (CMS), keeping the development cost lower. A larger catalogue of several hundred or thousands of products typically requires a dedicated setup process, data mapping, and in some cases a development team to handle the import, categorisation, and quality checking.
Beyond size, catalogue structure also matters. Additional product features such as bundled pricing, subscription options, or tiered discounts each require additional configuration and add to the overall cost of setup.
Design approach
For many ecommerce businesses, the experience of the website is a key differentiator. Founders want the look and feel of their store to reflect their brand identity and product positioning, and design is what determines that.
There are two broad approaches to ecommerce web design. The first is working with a pre-built theme, which platforms like Shopify and WooCommerce offer in a wide range of styles. These can be used as provided or customised to better match a brand's identity without a full custom design engagement. The second is commissioning a fully custom design built specifically for the brand, which produces a more distinctive result. The cost of custom design depends entirely on the experience level and scope of the designer or agency engaged.
Features and integrations
All ecommerce stores are built on the same core set of features: product listings, cart, checkout, and payment gateway. Platform subscriptions cover this baseline functionality. Where cost increases is when features beyond the standard set are required.
For example, a business that needs its online store to sync inventory with a physical retail point-of-sale system requires a custom integration that is not available out of the box. Similarly, connecting the store to an external customer relationship management (CRM) platform, an accounting system, or a third-party shipping application programming interface (API) each adds development time and cost.
Payment setup
Payment setup is a technical requirement for every ecommerce store, and the scope of that setup affects cost. Singapore ecommerce businesses typically need to support PayNow, major card networks such as Visa and Mastercard, and at least one digital wallet like GrabPay. Setting up, testing, and quality-assuring multiple payment methods at checkout requires configuration time and adds to the development scope.
Who builds it
The choice of who builds the site directly affects both the cost and quality of the output. Freelancers generally charge less than agencies but offer a narrower scope, less structured project management, and limited post-launch support. Agencies charge more but bring market knowledge, a managed build process, and ongoing accountability.
For Shopify specifically, the platform maintains a Shopify Partner programme, a directory of certified developers and agencies. Engaging a Shopify Partner provides an additional level of confidence in the vendor's platform expertise. Similarly, for PSG-funded builds, only vendors listed on the GoBusiness approved vendor list are eligible, regardless of the platform chosen.
Ecommerce website development costs in Singapore (2026)
Ecommerce website development costs in Singapore fall into three broad tiers based on the scope and nature of the website. The right tier depends on the stage of the business, the size of the product catalogue, and the level of customisation required.
Basic ecommerce store: SGD $1,500 to SGD $6,000
A basic ecommerce store is built on a platform like Shopify or WooCommerce with a pre-configured theme and standard payment gateway integration. It is suited to businesses with a smaller catalogue launching their first online store. The goal at this tier is to get a functional, well-structured store live at a manageable cost, with the intention of validating the channel before committing to a larger investment.
Stores in this tier are typically built by a freelancer or an entry-level agency and take 2 to 4 weeks to complete.
Mid-level store: SGD $8,000 to SGD $20,000
A mid-level store involves custom design work on top of a platform foundation, alongside integrations such as CRM tools, shipping management, and search engine optimisation (SEO) setup. The information architecture is more carefully considered, and more time is invested in how the store is structured and presented.
This tier is suited to growing businesses with an established product range and a customer base that expects a more polished online experience. Stores in this range are typically built by a web agency with ecommerce experience and take 6 to 12 weeks to complete.
Enterprise or custom build: SGD $25,000 to SGD $50,000 or more
A custom build is developed from scratch without relying on a platform like Shopify or WooCommerce as the foundation. This allows for fully bespoke checkout flows, complex product databases, advanced user experience features, and multi-channel integrations that off-the-shelf platforms cannot accommodate.
This tier is suited to established businesses with significant transaction volumes or highly specific technical requirements. It is also suitable for startups with in-house technical resources that want complete control over every part of the customer funnel. Open-source platforms like Magento are also commonly used at this tier, as they offer greater flexibility than Shopify or WooCommerce while still providing an established development framework. Custom builds typically take 1 to 3 months to complete. Most SMEs starting out do not need a custom build. Starting on a platform and migrating later if growth demands it is typically more cost-effective.

Ongoing ecommerce website costs
Website development is typically the main upfront investment in building an ecommerce presence, but it is not the only cost. The platform, payment processing, maintenance, and other operational costs all add up over time and vary depending on the build type chosen.
Platform and hosting costs
Platform and hosting costs differ across the three build types and are a key factor in the true annual cost of the website:
- Shopify: SGD $39 to SGD $150 per month, which includes hosting, SSL certificate, security updates, and platform access. Higher-tier plans unlock additional features and lower transaction fees
- WooCommerce: hosting at SGD $20 to SGD $80 per month. SSL certificate is typically included with modern hosting providers. Technical maintenance is the responsibility of the business or its developer
- Custom build: unlike hosted platforms, custom builds require the business to directly rent server space from a hosting provider. Costs vary based on traffic volume, infrastructure requirements, and the level of technical management needed, and typically require dedicated developer
- Other hosted platforms: platforms such as BigCommerce, Wix, and Squarespace offer similar hosted models to Shopify, generally priced between SGD $20 to SGD $120 per month depending on the plan and features
Payment gateway fees
Every sale on an ecommerce store passes through a payment gateway, which charges a fee per transaction. These fees are a variable cost tied directly to revenue. They increase as the store grows. Typical rates in Singapore for 2026:
- Domestic SGD card payments: 2.8% to 3.4% plus SGD $0.50 per transaction
- International card payments: approximately 3.9% plus SGD $0.50 per transaction
- PayNow: approximately 1.3% per transaction
- Foreign exchange (FX) markup: typically an additional 1% to 2% on cross-currency transactions
For a full breakdown of payment options, see Aspire's guide on ecommerce payment solutions.
Ecommerce website maintenance costs
Maintenance requirements vary significantly by platform. Hosted platforms like Shopify, BigCommerce, and Wix manage security updates, platform updates, and server infrastructure on the business's behalf, with support available directly through the platform. Third-party maintenance costs for hosted platforms are therefore lower. WooCommerce and custom builds, where the business owns the technical infrastructure, require more ongoing maintenance. Typical monthly costs in Singapore in 2026:
- Basic maintenance plan: SGD $150 to SGD $400 per month, covering security updates, platform and plugin updates, and backups
- Standard ecommerce maintenance: SGD $400 to SGD $800 per month, adding performance monitoring and content changes
- Full-service ecommerce support: SGD $800 to SGD $1,200 per month, covering bug fixes, performance optimisation, and ongoing content management
Plugins and apps
Platform subscriptions cover the core ecommerce functionality. Additional tools such as email marketing, loyalty programmes, product review systems, advanced search, and upsell features are typically added through third-party apps and plugins, each of which carries its own monthly subscription fee. A realistic budget for these is SGD $50 to SGD $300 per month, and it tends to grow as the business adds functionality over time. Custom builds typically have lower ongoing app costs but higher development costs when new features are required.
Domain name
A domain name is purchased for a set period, typically 1 to 2 years, and must be renewed to remain active, making it a recurring annual cost. Singapore domains with .sg or .com.sg extensions cost SGD $55 to SGD $80 per year. International .com domains cost SGD $14 to SGD $25 per year.
Ecommerce web design costs: freelancer vs agency in Singapore
Beyond the platform decision, choosing who builds the store is one of the most consequential decisions in the build process. The three main options each carry different cost and quality profiles.
- Freelancer: SGD $1,500 to SGD $10,000 for a basic to mid-range ecommerce build. Lower cost, but typically narrower scope, less structured project management, and limited post-launch support. Best suited to founders who have clear specifications and the technical confidence to manage the entire process themselves
- Local Singapore agency: SGD $6,000 to SGD $30,000 for mid to enterprise ecommerce builds. Higher cost, but brings market knowledge, a structured build process, and post-launch support. Additionally, most Singapore agencies are familiar with the PSG grant process and can help structure a project to qualify for funding
- Overseas developer: development costs are typically lower, but factors such as communication overhead, time zone differences, and revision cycles can affect the overall timeline and quality of delivery
Regardless of who is engaged, any proposal should be reviewed carefully to confirm it includes payment gateway setup, product catalogue configuration, quality assurance testing, mobile responsiveness, and post-launch support. Many lower-cost proposals exclude some of these items.
How to reduce ecommerce website development costs in Singapore
Use the PSG ecommerce grant
Eligible Singapore SMEs can claim up to 50% of ecommerce website development costs through the PSG ecommerce grant. The grant covers development costs for pre-approved ecommerce solutions through vendors listed on the GoBusiness portal. For a mid-level store costing SGD $15,000, the grant reduces the out-of-pocket cost to SGD $7,500. For eligibility criteria and a step-by-step application guide, see Aspire's full guide to the PSG ecommerce grant.
Start with a platform build, not a custom build
For most SMEs, Shopify or WooCommerce covers all the functionality needed to launch and grow at a fraction of the cost of a custom platform. A custom build is appropriate when the business has genuinely outgrown what platforms offer, not as the starting point. Starting with a platform build also makes it significantly easier to qualify for PSG funding.
Scope the build tightly
Every additional feature, integration, and customisation adds cost. Starting with a minimum viable store, meaning only the features needed to launch, and adding functionality incrementally based on how customers behave enables lower costs and faster launch timelines.
A phased, data-driven approach also gives founders a stronger foundation for expansion decisions. Each new feature or integration can be evaluated against real performance data which leads to more targeted investment as the business grows.
Managing ecommerce finances after the build
The website development budget is one part of the financial management of an ecommerce business. Once the store is live, the ongoing costs of running an ecommerce business, including supplier payments, payment processing, marketing, and logistics, need to be tracked and managed efficiently. Aspire's ecommerce solutions are designed to help founders manage exactly this, giving visibility and control over outgoing business costs as the store scales.
