    FAQ
    Answers to your most important questions

    Here you will find answers regarding indirect procurement, the single-creditor model, and working together with PSG. If your question is not listed here, please feel free to contact us directly.

    General Information on Indirect Procurement

    What is Tail Spend?
    Tail spend refers to the portion of procurement volume that falls on many small, irregular orders with a wide variety of different suppliers, often accounting for over 80 percent of suppliers but only a small fraction of the total volume. PSG addresses this unclear area directly with its Marketplace and SpotBuy solutions.
    What is the difference between strategic and indirect procurement?
    Strategic procurement concerns the high-volume commodity groups that are crucial for core operations. Indirect procurement covers everything that keeps operations running without being part of the actual product, such as office supplies, IT accessories, or services. PSG specializes precisely in this indirect area.

    The Single-Creditor Model

    What is PSG's single-creditor model?
    No matter how many suppliers are involved in procurement, you receive a single invoice from PSG. PSG is your central point of contact for ordering, delivery, invoicing, and payment, consolidating all supplier relationships behind it.
    For which company size is PSG suitable?
    The target audience includes primarily companies with more than 1,000 employees and an annual tail spend of over 1 million euros in indirect procurement.

    Marketplace, SpotBuy, and eProcurement

    What is the PSG Marketplace?
    The PSG Marketplace is a standardized catalog solution with over 70 million items from more than 200 suppliers. It covers over 90 percent of typical demand regardless of industry and can be integrated into existing eProcurement and ERP systems.
    What is PSG SpotBuy?
    PSG SpotBuy is the solution for spot purchases, i.e., goods and services not stored in the regular procurement or ERP system. From inquiry to invoice, the entire process is handled via PSG as the sole creditor.
    What is PSG eProcurement?
    PSG eProcurement supports companies that want to manage their suppliers and users independently through digital transaction platforms and marketplace systems, including catalog and free-text orders as well as integration into existing ERP systems.

    For Suppliers

    How can I become a supplier at PSG?
    Interested suppliers send an inquiry via the application form on the "Become a Supplier" page. PSG then gets in touch and discusses possible partnership models around Marketplace and SpotBuy.

    Certification and Collaboration

    Which certifications does PSG hold?
    PSG operates a quality management system certified according to ISO 9001 and an environmental management system certified according to ISO 14001. The EPSA Group was awarded the EcoVadis Platinum Medal in 2025 and received the CDP "B" Score.
    How does collaboration with PSG work?
    In four steps: Analyze the status quo, develop action recommendations, technical and organizational implementation, followed by long-term support and care by a personal team.

    Let's Talk

    Do you employ more than 1,000 staff and prefer not to deal with an annual tail spend of over €1 million? Would you like to have just one instead of thousands of creditors for indirect procurement? Do you also require transparency and compliance with ESG regulations, from the LkSG to proof of CO2 reduction, even for one-off purchases? Then you should get to know us to see how we have achieved significant, sustainable process cost savings for our clients for over 30 years and implemented digital processes in the “tail-end” of procurement.
