FICO, also called Finance and Controlling, helps integrate the accounting side of a business. All the financial sections like Accounts Receivable, Accounts Payable, General Ledger, Tax, etc are incorporated into SAP. It makes month ends much easier in companies now with all the automation. Controlling, on the other hand represents the flow of costs and revenues from the transactions that take place in the company.  It helps to track internal costs within the company.
