A donation is a gift of money to an organization. Donations can be one-time gifts or recurring. They can also be given to fulfill a prior pledge. Donations can be independently given or can be tied to a particular campaign and/or appeal. Donations must, however, be associated with a donation fund to get the proper accounting code. Donations can be paid for with cash, check, electronic check, or credit card and are typically tied to a particular person who has a record in the main database. You can also send acknowledgement letters to donors and record the date that a donation is acknowledged.
