Make sure you clearly define what you want to achieve with a cash flow forecast and design the categories, the horizon and the interval accordingly.
Take a hard look at your ERP and analyse wether you can reuse data from various modules to base the cash flow forecast with existing data. Your financial status will also contain a wealth of information to be used.
Your business might be cyclical. Use this to your advantage to improve forecasting quality
Your first cash flow forecast will be (really) far from perfect. Analyse why, take action and repeat this for every future forecast.
Forecasting operational cash flows is Step 1. Always ask your entities how they want to fund deficits or invest any surpluses resulting from these cash flows as Step 2.
Play around with the cash flow forecast to see what happens if… currencies fluctate, markets detoriate, projects are delayed or a volcano decides to erupt …
Share your analysis with your entities and give them a chance to learn for the next round of forecasting.
Prevent any data inconsistencies before they even hit your desk with smart checks on the cash flow forecast data.
