Accounts Payable are responsible for processing timely and accurate payments to suppliers, consultants and individuals, in a multitude of currencies, to enable the College to carry out its world-class teaching and research. The department ensures compliance to financial policies and procedures relating to the purchase to pay cycle whilst ensuring efficient payment.

The department uses sophisticated electronic invoicing technology, through our partner Tungsten. This enables the team to process a growing volume of invoices whilst maintaining high standards.
