Webshop & E-commerce Development

Shopify Plus, WooCommerce or headless commerce with the integrations a real store needs.

Scope my project

A store is a system, not a theme. Behind the storefront sit product data, stock, payments, shipping, tax and the ERP that has to agree with all of it. We build stores where those pieces connect, so the team spends time selling rather than reconciling.

Platform choice follows the business. Shopify Plus for speed and ecosystem, WooCommerce for content-led stores, composable commerce with Medusa or commercetools when the catalogue or channels outgrow a single platform.

How we're different
  • Our marketing team's e-commerce specialists review the store for feeds, SEO and conversion before launch.
  • Integrations are built with monitoring, so a failed order sync is an alert rather than a customer complaint.
  • We plan for peak: load testing and a launch runbook are standard.
Who this is for
  • A consumer goods manufacturer moving from wholesale-only to direct sales in several markets.
  • A retail group replatforming a store that its ERP, warehouse and loyalty systems all depend on.
  • A B2B distributor with customer-specific pricing, approval workflows and a catalogue in the hundreds of thousands.
Signals you need this now
  • Stock on the storefront and stock in the warehouse disagree daily.
  • Peak trading brings outages or a checkout that slows to a crawl.
  • Plugin updates break integrations and nobody knows until an order is missed.
  • Expansion into a new market means a new store built from scratch.
