e-Commerce Development FAQs

We specialise in Shopify and WooCommerce, which together account for over 50% of all ecommerce stores globally. We also work with Magento (Adobe Commerce) for enterprise clients. Our team has hands-on experience across all three platforms, allowing us to recommend the right fit for your budget, technical needs, and business model

The right platform depends on four factors: your budget, your technical requirements, how much customisation you need, and your long-term growth plan. Shopify suits most small-to-mid-size businesses launching or migrating. WooCommerce suits businesses needing full customisation and already running WordPress. Magento suits large enterprises with complex catalogues and workflows. We offer a free 30- minute consultation to help you make the right decision without sales pressure.

Yes. We build both B2C stores (selling direct to consumers) and B2B stores (selling to trade customers with features like account-based pricing, bulk ordering, purchase order terms, and quote request workflows). Many of our clients run both B2B and B2C channels from a single store setup.

Yes. We regularly take over existing stores that need a redesign, performance overhaul, or new functionality. We start with a full audit of your current store covering speed, mobile UX, conversion rate, SEO, and security – then present a clear improvement roadmap before any work begins.

Every ecommerce store we build includes SEO foundations as standard: clean URL structure, proper heading hierarchy, schema markup for products and breadcrumbs, XML sitemap configuration, canonical tags, and image alt text. We also optimise page speed (a direct Google ranking factor) and ensure mobile-first indexing compliance. For ongoing SEO campaigns, we offer dedicated ecommerce SEO services.

We integrate all major payment gateways including Stripe, PayPal, Authorize.Net, Braintree, Square, and regional gateways specific to markets in the US, UK, Australia, and India. We also set up buy-nowpay-later options like Klarna, Afterpay, and Sezzle where required
