Held in-house with Wyvern DataCare, the list is claimed to be the cleanest, most up-to-date listing of top national charity and voluntary organisations.
Selections are available by income level, job title and charitable cause, which includes sectors such as: animal and wildlife; armed service; elderly; and health and overseas etc.
Previous and continuous users include: travel; office supplies and stationery; software; recruitment; events; management training; publications; and legal and financial related products.
