Expense and cost recovery system

An expense and cost recovery system (ECRS) is a specialized subset of "extract, transform, load" (ETL) functioning as a powerful and flexible set of applications, including programs, scripts and databases designed to improve the cash flow of businesses and organizations by automating the movement of data between cost recovery systems, electronic billing from vendors, and accounting systems. It is most applicable to companies that bill back clients for time and costs.
