Customer Koszulkowo

Koszulkowo.com is one of the biggest online stores in Poland that sells gadgets and print-on-demand t-shirts. The offer includes over 100 000 products in a variety of configurations and around 6000 different patterns. Koszulkowo.com cooperates with hundreds of different artists who create designs for printing as well as influencers (e.g. Loesje). The designs feature modern style and carry a strong pop culture message. The customer quickly reacts to trends and popular memes, thus constantly introducing new patterns to their collections (the most famous is, among others, “Think different” with a pear in rainbow colors).

Koszulkowo.com has a modern science park and machines dedicated to printing in various techniques. They also provide wholesale orders as well as custom designs.

Initial situation

The customer came to us from another agency due to the lack of appropriate service. The focus was on transparency of communication and billing. The store needed further optimization in terms of UX and new features on the store – the customer wanted to grow in marketing and wanted to implement new features on the store that would help them stay ahead of the competition. Support in case of any bugs in the store was also very important. 

Common objective

The main goal of our cooperation was to improve some visual aspects of the store design, improve the speed of the website (i.a. increasing conversion rate), introduce better marketing campaigns thanks to additional integrations as well as the ability to export data from the store in various formats. Additionally, the number of errors preventing sales on the store had to be reduced.
