How to Pick the Right Shopify Plus Agency for Your Brand

  1. Match expertise to your stage. Pre-$5M brands need lean, growth-minded partners. $10M+ brands need agencies with replatforming and integration chops.
  2. Validate category fit. Ask for case studies in your vertical - fashion, beauty, B2B, food, electronics.
  3. Confirm post-launch model. A good agency stays on as a growth partner, not just a builder.
  4. Check the tech stack. Make sure they're comfortable integrating your returns, shipping, OMS, subscriptions, and loyalty stack.
  5. Talk to references. Speak with two clients at your scale before you sign.

Bonus: Make Your Shopify Plus Store Post-Purchase Ready

Most agencies focus on storefront and acquisition - but the post-purchase experience (returns, exchanges, shipping, tracking) is where margin and loyalty live. While you're evaluating Shopify Plus agencies, also evaluate your post-purchase stack:

Pair the right Shopify Plus agency with the right post-purchase stack, and you've got a system built to scale to nine figures.
