How to choose the right e-commerce agency.

Not every agency will fit every project. Consider platform expertise: if you're committed to Shopify, agencies like Significa Ask Phill, We Make Websites, or By Association Only bring deep platform knowledge. Think about scale: are you a mid-market brand looking to grow, or an enterprise needing complex integrations? And don't overlook specialisation: some agencies excel with luxury brands (By Association Only, VAAN), others with D2C scaling (Ask Phill, We Make Websites), and some bring end-to-end product thinking (Significa).

Europe's e-commerce agency landscape offers deep expertise across platforms, industries, and brand types. From Shopify specialists like Ask Phill and We Make Websites to design-led agencies like By Association Only and VAAN, to full-service partners like Significa, the choice depends on your specific needs. Whether you're migrating platforms, scaling operations, or launching a new brand, these agencies bring proven track records in building e-commerce experiences that perform.
