Three case studies illustrate that although corporate treasurers do share common expectations and goals they are a diverse community. What treasurers need from a payment solution will depend on factors such as whether the company is centralised or decentralised; the nature of the payments; the geographical spread of the organisation; and the level of control required by the treasurer. Case study one looks at the treasury issues addressed by a large oilfield services company which needed its treasury function to be flexible while maintaining control; case study two examines how a group treasury of a multinational corporate moved away from a decentralised regional framework into a model that combined central treasury control with local subsidiary ownership; case study three looks at the need for accounting information to be available in London and New York.
