ARK's Journey From Legacy to Composable

Ark is Norway's largest bookstore chain - they handle up to 50.000 orders per day. With the ambition to be the most innovative bookstore chain, they aim to provide their customers with the most accessible means of purchasing books.

They struggled with legacy systems that were too complex and costly. So they started a project where the main focus was on optimizing the system architecture.

ARK solved this by implementing a state-of the-Art MACH architecture, with Omnium Order Management System (OMS) as a central hub.


Omnium OMS digitally oversees the entire order lifecycle, from entry to fulfillment and after-sales service. It ensures free flow of product, customer and order information to unify their sales channels.

The Result?

  • 50 % efficiency increase in several internal tasks
  • 15 % increase in the conversion rate
  • 25 % boost in revenue - just one month after launching the new online solution

Sign up to the webinar to learn how Norway's largest bookstore chain achieved these results!

We chose Omnium because we needed an order processing system to simplify interfaces in stores with complex order flows. Omnium has proven expertise in this area. In the old ARK solution, this was internally built into the ERP system, which was both slow and had unsatisfactory user interfaces.
