Finance: how to ensure accurate cashflow forecasts

You should establish a monitor system in the first place to detect any possible cashflow gap which will occur during your production and operation. This system can calculate the balance between your income and expenditure on a daily base. And should there be any sign of cashflow problems the system will warn your staff to do something about it before hand.
In order to achieve the accuracy you must set up a report system which demands every manager report the current financial status of his or her departments. The information will be collected everyday for you to take consideration.
