Business Functions is a free function library for Microsoft Excel designed to make business plans, budgets, structured financings and cashflows. Business Functions is in use by large companies, business advisors, and consultants because it saves time - time in development, time in maintenance, and calculation time.

Business Functions is based on the principle that using a purpose-built function in a cell is more transparent, reliable, flexible and accurate than an overly long Excel formula.
This principle has been extended to a comprehensive projections functions that project cashflows and accruals with a high degree of daycount accuracy.
