How to choose the right expert (quick checklist)

• Confirm Shopify Partner / Shopify Plus Partner status (Shopify directory). (Shopify.com)
• Look for portfolio projects matching your industry (fashion, cosmetics, food, B2B).
• Ask for examples of personalized features you need: custom product builders, personalization engines, headless setups, ERP or PIM integrations.
• Request references and examples of measurable results (conversion lifts, load times, revenue increases).
• Get a written scope and milestone timeline before committing.

If you’d like, I can:

• Pull together 3–5 direct contact links and recent portfolio examples for 2–3 of these agencies (I’ll fetch current contact pages and case studies).
• Or recommend which agencies best match your budget and project type if you tell me approximate budget and whether you need Shopify Plus, headless, or multilingual/multi‑currency support.
