E-Commerce Development FAQs

how much does it cost to build an online store in singapore
E-commerce development in Singapore typically ranges from SGD 8,000 for a basic Shopify or WooCommerce store to SGD 50,000+ for complex custom solutions with advanced features. The cost depends on your product catalogue size, custom functionality, payment and shipping integrations, and design requirements. TerrisDigital provides a detailed quote after a free scoping session.
best ecommerce platform for singapore business
The best platform depends on your business model. Shopify is ideal for businesses wanting a fully hosted, low-maintenance solution with predictable monthly costs. WooCommerce suits those needing full control and heavy customisation without transaction fees. Magento is built for large catalogues and enterprise-scale operations. TerrisDigital helps you evaluate each option against your specific requirements before committing.
shopify vs woocommerce singapore which is better
Shopify charges a monthly subscription plus transaction fees but handles hosting, security, and updates for you. WooCommerce is free to install on WordPress and has no transaction fees, but you manage your own hosting and updates. Shopify is simpler to operate while WooCommerce offers more customisation flexibility. The right choice depends on your technical comfort level and budget structure.
how to accept paynow and grabpay on online store
PayNow and GrabPay can be added to your online store through payment service providers like Stripe Singapore, HitPay, or PaySG that support local payment methods. These integrate with Shopify, WooCommerce, and custom-built stores. TerrisDigital configures these gateways alongside credit card and PayPal options so your customers can pay using their preferred method at checkout.
how long does it take to launch an ecommerce website
A standard e-commerce store on Shopify or WooCommerce takes 8 to 12 weeks to develop and launch. Custom-built stores with unique features like product configurators, subscription billing, or multi-vendor marketplaces may take 16 to 20 weeks. Factors affecting timeline include catalogue size, number of integrations, and the complexity of custom functionality required.
do i need a developer to set up shopify store
You can set up a basic Shopify store yourself using templates, but a developer is recommended if you need custom design, unique functionality, third-party integrations, or optimised performance. DIY stores often look generic and lack the conversion-focused design that drives sales. TerrisDigital builds Shopify stores with custom themes and tailored features that stand out from template-based competitors.
how to set up shipping for ecommerce singapore
E-commerce shipping in Singapore involves integrating with local couriers like Ninja Van, J&T Express, and SingPost, and configuring shipping zones, rates, and estimated delivery times. For regional delivery across Southeast Asia, you can add international carriers like DHL and FedEx. Most platforms support real-time shipping rate calculations based on weight, dimensions, and destination.
ecommerce website gst singapore how to handle
Singapore GST (currently 9%) must be included in displayed prices for B2C sales or clearly itemised at checkout. Your e-commerce platform should automatically calculate GST on taxable goods and generate GST-compliant invoices. TerrisDigital configures GST settings correctly during store setup and integrates with accounting software like Xero to automate GST reporting for IRAS submissions.
can i migrate my online store to a new platform
Yes, e-commerce platform migrations are common. The process involves transferring products, customer data, order history, reviews, and SEO data to the new platform. Proper 301 redirects must be set up to preserve search rankings. A well-planned migration typically takes 4 to 8 weeks with minimal downtime and zero data loss when handled by experienced developers.
how to increase ecommerce conversion rate singapore
Key strategies include offering local payment methods like PayNow and GrabPay, displaying prices in SGD, providing fast local shipping options, optimising page speed to under 3 seconds, and building trust with clear return policies and customer reviews. A/B testing checkout flows and reducing form fields can also significantly improve conversion rates for Singapore shoppers.
ecommerce pdpa compliance singapore what do i need
E-commerce stores in Singapore must obtain explicit consent before collecting customer data, display a clear privacy policy, encrypt personal data at rest and in transit, and implement proper data retention procedures. Your checkout process should collect only necessary information, and marketing emails require opt-in consent. TerrisDigital builds PDPA compliance into every e-commerce project from the start.
how to integrate xero with online store singapore
Xero integrates with Shopify, WooCommerce, and most e-commerce platforms through official plugins or third-party connectors like Amaka or A2X. The integration automates invoice creation, syncs payment data, calculates GST, and reconciles transactions — eliminating manual data entry. Setting up the mapping between your store products and Xero accounts correctly from the start saves significant time on bookkeeping.
