Our client, the Seidensticker Group (industry/clothing), was faced with the task of significantly reducing indirect procurement costs (non-merchandise) in a market characterised by store closures, online focus and outsourced logistics. The aim was to achieve transparency across all product groups, closer integration of the specialist departments with purchasing and a holistic cost reduction through direct negotiations, tenders and product group strategies. Procedure: Accounts payable-based data analysis and interviews, development of the product group strategy, subsequent tenders and negotiations. Result: significant savings of up to 37 % for existing suppliers and up to 50 % for alternative suppliers. Examples per product group: insurance 37.3 %, IT hardware 32.1 %, shopfitting 27.4 %, printing materials 18.7 %, vehicle fleet 31.2 %; additional optimisations in telecommunications and time recording, among others. The customer now has transparent purchasing structures, lower overheads and consolidated contract data.
