The American Express Business Travel Account (BTA) is a simple method for managing the administration of travel costs. It allows authorised users to charge travel related expenses through a designated travel agency, centralising travel expenditure and allowing better management of your travel costs. It is an ideal billing solution for corporations requiring detailed air-travel expenditure reporting through a centralised billing, reconciliation and payment process, plus it’s convenient for travelers not issued with a Corporate Card, such as contractors, infrequent travelers and consultants.
