93% Item Recognition: How Steel Trader Köstner Automates Quotes and Orders with Agentic AI
Read the turian x Köstner success story!


Company Profile
Köstner Stahlzentrum GmbH is part of Richard Köstner AG and trades steel, stainless steel and aluminium from four sites in Bavaria and Saxony. It also offers processing, from sawing and blasting to its own rebar bending shop. Around 220 people work in the steel business.

I would definitely recommend investing in automated case processing. What matters, though, is that people stay involved and continue to make the final decisions themselves.

The challenge lay in the high number of requests, the many line items per document and the wide product range: around 20,000 items in different steel grades, plus more than 15,000 customer accounts. Every second request arrives as plain email text, and every fifth line item is a cut-to-length piece. Orders and requests usually contain no item number, only a technical description of the product. New employees in particular often lacked the product knowledge for this.
For Köstner, very high product recognition was essential, which is no trivial task in steel trading. What tipped the decision in favour of turian was the trusting collaboration from the very beginning, along with the contractual, technical and commercial terms.


According to Trautner, without turian everyday work would be far more dominated by manual routine data entry.
Our customers expect very fast processing. A request comes in at 7 a.m. on a Monday morning, and by 7:30 the customer already has their quote. If we only follow up at 10 a.m., the order may already have gone to a competitor. With turian, we can quote faster and follow up sooner.


Right from the start, without extensive guidelines, we achieved a recognition rate of almost 77%. Through weekly joint meetings and feedback from day-to-day practice, we have continuously improved item recognition to around 90% today. That means we have reached the minimum rate we set ourselves.
Acceptance varied from site to site at first. turian has since become established, and the teams love using it. What they value most is that the tedious entry of header data and line items has largely disappeared.
