Global cash management is a lot trickier than domestic cash management, not just because of the variety of investment options, but because of the various types of money used. When you are working with anything other than the United States dollar, you always have to adjust for that. Technology today makes it much easier to do such things.
In order to drive your working capital management in such a way as to be able to do accurate and in-depth cash flow forecasting that gives you the results you want, you have to use technology that works in real time. Robust reporting with real time technology is the only way that global cash management can be done, without a lot of guess work. Since your financial strategies rely on solid numbers and data, real time technology is really the only option you have if you want to see even moderate success in this area.
