From days to hours: How kessler standardized and accelerated its quoting and procurement processes with Luminovo

kessler Systems GmbH unites all services under one roof: from software and hardware development through design and prototyping to the manufacturing of electronic assemblies and devices. This results in seamless solutions – from concept to series production. For several years, kessler has worked closely with Luminovo, not only as a customer, but as an active development partner. Through this ongoing collaboration, the company has fundamentally modernized its internal workflows while providing valuable feedback that helped shape the evolution of Luminovo itself.

The result: significantly faster quoting processes, optimized material costs, and higher quality in both purchasing and customer support.

“I press a button and can generate a customer quote for a prototype within a single day. That’s a huge advantage for us. And something we have to deliver as a small but agile company.”

— Tobias Schöppner, Strategic Purchasing & Procurement

The challenge: Manual work, high costs, and lack of transparency

Before adopting Luminovo, many of kessler’s processes were still manual. Quotes were prepared in Excel, BOMs had to be cleaned up line by line, and component prices were pulled from online retailers. This approach came with several pain points:

• Lengthy turnaround times: Prototype quotations typically took four to five days to complete.

• Poor data quality: The preparation of the bills of materials was previously characterized by several manual steps, which should gain significant efficiency through new measures.

• High material costs: Due to time pressure, the team often relied on expensive catalog prices, which impacted both margins and competitiveness.

• Lack of sourcing visibility: There was no central overview of supplier RfQs or quote statuses.

• Error potential: Due to the manual processing of complex bills of materials, there is an inherent potential for deviation, which kessler is further reducing with the new approach.

  
  

“Just to prepare a basic cost calculation for 100 to 150 components took three to four hours – and the final quote was only ready after four or five days.”

The solution: End-to-end digitalization with Luminovo

kessler decided to fully digitize its quotation and procurement processes with the help of Luminovo. As one of Luminovo’s earliest customers, kessler was deeply involved in the product’s design and feature development. Through continuous feedback, the team played a key role in helping Luminovo evolve into a new industry standard for digital quoting in electronics manufacturing.

1. Faster quotation turnaround

By integrating the API with our suppliers and distributors, kessler is able to significantly reduce the time-consuming manual price research. This accelerates internal processes and creates the foundation for more efficient quotation creation.

“We used to have requests that took several days. Today, with good data, we can deliver a quote within a few hours – sometimes even the same day.”

— Tobias Schöppner, Strategic Purchasing & Procurement

2. Improved quality and proactive customer communication

Luminovo automatically detects BOM errors, obsolete components, and supply issues.
This allows kessler to proactively coordinate alternatives with customers, and flag potential risks early on, improving both quote quality and customer trust.

“Our customers appreciate when we point out discontinued components and propose alternatives. It helps them avoid costly redesigns and strengthens our customer relationships.”
— Tobias Schöppner, Strategic Purchasing & Procurement

3. Efficient purchasing and measurable cost savings

Through supplier APIs, stored discount curves, and special pricing logic, kessler has significantly reduced material costs. All prices and availabilities are now visible in one central dashboard, ensuring complete sourcing transparency. The integrated supplier RfQ tracking feature provides real-time visibility across all ongoing inquiries.

“In the past, we had to rely on expensive catalog prices. Today, we have full transparency across all supplier prices and can negotiate strategically.”

— Tobias Schöppner, Strategic Purchasing & Procurement

4. Centralized data platform and standardization

kessler now uses Luminovo as a central data source across many areas. Standardized data exports are created using individual templates, for example, for calculation, purchasing, or production. All relevant documents, quotations, and supplier PDFs are stored directly within the respective project, fully digital and version-proof.

“We now use Luminovo across all departments, and everything is standardized. That saves time and creates clarity.”

Outlook

Through close collaboration, kessler has contributed directly to building an emerging industry standard for quoting and procurement in electronics manufacturing.

Looking ahead, kessler aims to leverage Luminovo’s full potential, particularly in the areas of manufacturing cost calculation, expanded supplier APIs, and automated order processing.

“Luminovo delivers the intelligence we need. This makes the collaboration valuable to us and creates tangible benefits for our customers.”

— Tobias Schöppner, Strategic Purchasing & Procurement

The close partnership between kessler and Luminovo creates an innovation loop that drives both sides forward. The goal is clear: greater efficiency, better data quality, and a robust industry standard for quotation and purchasing processes.
