Imunoklub | Case Study Unification of two e-shops and more value from each visit

We have been collaborating with Imunoklub since 2013. We were there at its beginnings on BUXUS and gradually developed the solution through systematic adjustments, according to how the business itself grew. For a long time, we moved the e-shop forward step by step. However, with the growth of the business, there came a moment when further progress was no longer about individual improvements, but about how the entire system functions as a whole.

It wasn't just about the e-shop. The way the entire business operates changed - from purchasing to processing and delivering orders.

On this basis, we elevated the existing solution to a new level. We unified the Slovak and Czech e-shop, connected it with ERP ABRA, and significantly modified the loyalty program and purchasing process.

One Multi-Admin for Two E-Shops

The key step was to unify the Slovak and Czech e-shops into one system on CMS BUXUS. Outwardly, local specifics - language, content, and domains - were preserved. Internally, however, it is one common back office, which significantly simplifies management for the client.

Integration with ERP

For e-commerce to scale realistically, it must have order in its data. Therefore, we set ERP ABRA as the unequivocal source of truth. Everything essential about products, prices, stocks, and customers is managed from one place. BUXUS takes care of presentation, content, and the purchasing process. Thanks to bidirectional synchronization between systems, changes from ERP are immediately reflected on the e-shop and vice versa.

Digitization of a Custom Loyalty Program

The original loyalty program operated outside the e-shop and was based on a number of manual processes. Customers entered codes from product packages, for which they earned loyalty points and subsequently rewards. These were processed and dispatched separately, apart from regular e-shop orders.

With hundreds of thousands of codes entered and tens of thousands of gift shipments, it was no longer a minor operation. The loyalty program required a lot of time and work, complicated logistics, and also brought considerable costs for the separate dispatch of rewards.

We have transferred the new loyalty system directly into the e-shop and ensured its technological design and development. Benefits, rewards, and gifts are now a natural part of the shopping process and are available to the customer in real-time.

A fundamental change also occurred in the background. Rewards, which were previously processed and dispatched separately, are now packed directly with the order. The result is less manual work, simpler logistics, and lower operating costs for the loyalty program.

Loyalty program without unnecessary manual work

Before

95,372

shipments sent only with gift items

Loyalty rewards were processed separately from orders and required separate shipping.

Today

The loyalty program is part of the e-shop and shopping process. Rewards are added directly to the order and shipped together with the purchase.

Less manual work. Simpler logistics. Lower costs.

Progress Instead of Collecting Points

The new loyalty program operates on the principle of progress instead of the traditional point collection. The customer can clearly see where they stand, what benefits they are currently utilizing, and what they need to reach a higher level. We have directly linked this principle with the shopping process - even while browsing the e-shop and in the cart, the customer is motivated to increase the order value.

Product Sets as a Tool for Increasing Order Value

We have designed a system of product sets that are created by combining existing products without the need for separate storage. This allows the client to flexibly create packages according to the current strategy - whether it is to support specific products or seasonal campaigns.

Higher Conversion Rate

+11.9 % Conversion Rate (YoY)

More visitors completed a purchase. An optimized checkout, better navigation, and redesign of product pages removed barriers in the purchasing process.

Stable Retention

52.3 % Revenue from returning customers

More than half of the revenue was generated by returning customers. Their conversion rate increased by 20.6%, confirming that the migration did not threaten customer loyalty.

Higher Visit Value

+10.8 % Revenue per visit (YoY)

Each visit to the e-shop brought more revenue. A better user experience translated into more efficient sales without the need to increase traffic.

“This project was not just a redesign of the e-shop. The goal was to elevate the functioning of e-commerce to a new level - from order processing and customer data to logistics.

One of the biggest challenges was transforming the long-established loyalty system. We retained what customers were accustomed to, but significantly simplified the entire process. Moving loyalty rewards directly into the order resulted in less manual work for the client, simpler logistics, and lower costs, while customers gained a more convenient way to redeem benefits.

The success of the project relied not only on technology but also on close collaboration, open communication, and thorough expectation management.”

We have been collaborating with the agency ui42 for many years - they were also present at the creation of the original Imunoklub, which brought us tens of thousands of loyal customers. Therefore, the choice of supplier for the new Imunoklub was clear. The cooperation is professional, client-oriented, and detail-focused, resulting in a project that we will benefit from and delight our customers with for many years to come.
