Competition in business sectors has increased very much during the course of the 21st century. In order for businesspersons to maintain a relationship with their customers and suppliers, they are required to stay in touch with them, and sometimes visit them at different locations all over the world. They also assign employees to market their products and service on their behalf. Business travel of this nature calls for expenditure on airfare, accommodation, food and other travel related expenditure. The expenses incurred by an employee can be filed in the form of a report for the purpose of reimbursement from the employer. These reports are referred to as expense reports. Expense reports serve the purpose of accounting for business expenditure and help in filing of tax returns.
