Similar to P & L forecasting that uses the main categories in your profit & loss statement for multiple years, P & L Analysis is more detailed to match your complete profit & Loss statement on a monthly basis. I have always used QuickBooks for my businesses, that is what I am familiar with. What ever you use for your business, the same system can be used to help you analyze your monthly and yearly progress.
Profit & Loss Analysis will give a consistent look of your profit and loss statement that will help keep you on top of where your money is, and where it is going. Thru your planning you will be able to compare your numbers and adjust your plan monthly if needed. The better you perform on analyzing and tweaking your operations to hit your plan, the faster you can reach your goals.
Goals in Business has a spreadsheet that you can customize to fit your profit & loss statement to help start analyzing your month to month numbers. The better you know your numbers, the faster you can start planning properly for your future to hit your goals.
