How Apparel Retailer Summum Improved Conversion Rates by 19% in Just 5 Weeks with Advanced Merchandising

Summum is a women's apparel fashion label established by Jos and Jorien Wijker in 1998. A down-to-earth Dutch brand with international appeal, focused on on-trend and timelessly classic designs prioritizing aesthetic appeal and comfort.

Conversion Rate Growth

The Challenge

Summum sought to implement advanced multiple-parameter product sorting to drive conversion rates, but needed to mitigate the risks of sales and revenue drops during the transition from single-parameter to multi-parameter sorting.

  • Increase overall conversion rates without impacting sales
  • Reduce non-moving inventory while improving conversion
  • Safely transition from single-parameter to multi-parameter sorting

The Solution

Using Kimonix, Summum balanced sales, conversion rates, variants with stock ratio, and inventory metrics. They developed advanced sorting incorporating 'how many sizes are in stock' into their merchandising strategy — a critical factor for fashion apparel.

Ask Phill, a Shopify Platinum Partner Agency, ensured smooth integration and implementation throughout the process.

The Results

In just five weeks, Summum saw a 19% increase in their store's overall conversion rate, successfully transitioning from single-parameter to multi-parameter sorting without any negative impact on sales.

Conclusion

What Summum Says

Kimonix is a great tool for merchandise collection pages, whether for very basic or more advanced (AI) strategies. One of the most critical factors for us, as a smaller eCommerce team, is that it is effortless to install and use by the end user — basically, no development needed.
