How to Choose a Shopify Plus Agency
The right agency depends on the complexity of the project and the outcomes the business wants to achieve.
Before selecting a partner, enterprise brands should evaluate:
- Experience with similar industries and business models
- Shopify Plus migration and replatforming capabilities
- B2B and international commerce expertise
- ERP, CRM, PIM, POS and OMS integration experience
- UX, accessibility and conversion optimisation skills
- Headless or composable commerce capabilities
- Project governance and communication processes
- Post-launch support and optimisation services
Shopify’s partner directory allows merchants to compare partners by services, location, pricing and partner tier. Shopify also states that partner tiers reflect factors such as platform experience and proven success.
Businesses should also ask agencies to provide case studies relevant to their requirements. A useful case study should explain the original challenge, the work completed, and the outcome, rather than presenting only brand logos or screenshots.
Final Thoughts
Each agency in this list offers a different combination of technical, creative and strategic capabilities.
Some are better suited to design-led consumer brands, while others specialise in B2B commerce, international expansion, complex integrations, unified commerce or continuous conversion optimisation.
Before making a decision, businesses should clearly define their platform requirements, operational challenges, budget, internal resources and post-launch expectations. Comparing agencies against these priorities will make it easier to select a Shopify Plus partner that can support both the immediate project and the company’s longer-term commerce plans.
