Especially in times of an economic boom following a crisis companies have to deal with the phenomenon of the working capital trap which signifies a company s increasing need for financial liquidity in times of hindered access to debt capital caused by the increasingly restrictive credit approval processes of financial institutions. As a consequence of cost savings this situation is often reinforced by a low level of inventory. This book takes up the problem and shows ways of escaping the trap by identifying and strengthening in-house financing potential. First different operating ratios will be introduced. These refer to the amount of capital committed to the flow of goods and to the amount of in-house financing possible. Subsequently methods for consolidating in-house financing that are affected by procurement processes will be presented from the company s and the supply chain s perspective. From a company s perspective the methods for consolidating the amount of in-house financing over the following topics: The Management of Payment Terms Inventory Management and Product Group and Supplier Management From the supply chain s perspective the following methods for extending the possible amount of in-house financing will be discussed: Finance-Oriented Supply Chain Sourcing Supply Chain-Oriented Supplier Financing Collaborative Cash-to-Cash Management Collaborative Cash Pooling and Netting Supply Chain Financing Platforms. The conceptual models will be clarified using a practical example from the automobile industry. Finally the Procurement Value Added (PVA(c)) approach will be presented a concept that measures the contribution of procurement to the company s success.
