FAQs
What prospects usually ask.
WooCommerce, Shopify, or custom — which platform should we use?
Shopify is the right default for most product retailers — fast to launch, predictable hosting, mature app ecosystem, low operational burden. WooCommerce makes sense when you already run on WordPress and want full control of hosting, content, and customisation. Bespoke or headless commerce (Next.js front-end with a commerce backend) is for catalogues, pricing models, or customer journeys that off-the-shelf platforms don't accommodate cleanly.How much does eCommerce development cost?
A polished Shopify or WooCommerce build typically lands between £6,000 and £25,000 depending on theme customisation, integration count, and product catalogue complexity. A bespoke or headless build with custom checkout, advanced personalisation, or unusual fulfilment logic is more like £30,000–£150,000. Ongoing platform fees and apps sit on top — usually £30–£500 a month.How long does an eCommerce build take?
A Shopify or WooCommerce store with a custom theme and standard integrations typically launches in six to ten weeks. A bespoke build with custom checkout flow, complex catalogue, or deep ERP/inventory integration is more like three to five months. Migrations from an existing platform usually add two to four weeks for product, order, and customer data.Do you migrate products and orders from our existing platform?
Yes. Product data, customer accounts, historical orders, and reviews can all be migrated between the major platforms (Shopify, WooCommerce, Magento, BigCommerce). We map data carefully, handle SEO redirects so existing rankings don't drop, and run the migration in a staging environment first so you can validate everything before cutover.Which payment providers can you integrate?
Stripe, PayPal, GoCardless, Klarna, Clearpay, Apple Pay and Google Pay are the common ones, plus regional providers like Worldpay and Adyen when needed. For B2B stores we often add invoiced payment, account-based credit terms, or integration with Sage / Xero for billing. The right mix depends on your customer base and average order value.Can the store handle subscriptions, memberships, or recurring billing?
Yes. On Shopify we'd typically use Recharge or Bold Subscriptions; on WooCommerce we'd use WooCommerce Subscriptions; on bespoke builds we'd integrate Stripe Billing or GoCardless directly. Each has trade-offs around dunning, plan switching, and customer self-service that we'll walk through against your specific subscription model.How do you connect the store to inventory or accounting systems?
We integrate with the common ones natively — Xero, Sage, QuickBooks for accounting, and Linnworks, Veeqo, or Cin7 for inventory and multi-channel order management. For ERP-grade integrations or unusual stock systems, we build custom middleware so orders flow through cleanly without manual re-keying. The aim is always one source of truth, not parallel ledgers.
