An alternative to the stand-alone cash flow forecasting systems is to use the cash planning and forecasting modules in the group accounting and financial control packages. Unit 4's OCRA provides a Cash Planning module that collects cash availability data from the group's ERP systems and banks and then combines this with subsidiaries forecasts to provide an overall cash flow forecast. It also generates liquidity and currency exposure forecasts. The system is typically used by large holding groups with annual sales of EUR200m+.
