What brands are on Shopify Plus?

Shopify Plus is the perfect option for both large retail stores and fast-rising ecommerce stars. 

It’s perfect for your brand if:

  • You're already doing $50,000 or more in sales each month.
  • You're gaining traction and quickly rising toward six-figure sales.
  • You're in need of an agile platform that can keep pace with industry innovation.


  • You're an established retailer just breaking into ecommerce or direct-to-consumer sales.
  • You're looking for continuous innovation from a worldwide team of ecommerce experts.
  • You needing to get ahead of competition and gain market share quickly.

Why Shopify Plus?

Guaranteed uptime. No matter how heavy the traffic or how many sales, your site will be there for your customers.

Sell where you want to. Web, mobile, social, bricks and mortar, wholesale... Sell everywhere your customers want to buy. Shopify Plus isn’t multi-channel, it’s every channel.

The easiest-to-use platform. Add products and promotions without a developer, automate your workflows, and see what is going on in your business – all with a single login.

Custom checkout. Bring your branding and custom functionality to your checkout experience to reduce abandoned carts and set your store apart from the competition.

Exclusive Shopify Plus features, apps and scripts. You’ll have access to a full range of Shopify Plus-only apps and the Shopify Plus API for any custom development solution you need.

Always-on support. You’ll have a dedicated account manager ready to answer your email or call 24/7.

The Couture Club

+28% conversion rate

After helping this premium powerhouse navigate the Shopify ecosystem and increase conversion rate by +28%, we levelled up their loyalty scheme, The Club, to produce a 58% increase in sign-ups.

"Moving to Shopify Plus would have been a lot easier if we'd worked with Underwaterpistol from the start! But we didn’t. The move itself wasn’t difficult, as Shopify makes it so easy. But initially we didn't get what we expected without the right team behind us. As soon as we started working with Underwaterpistol, we had an additional 30 people to support us with expertise and knowledge in different areas. It’s about finding the right agency to partner up with."

Scott Shashua, Director at The Couture Club
