Our non-profit gets many donations through American Express and other companies that charge a percentage to process the gift.  EX:  A person donates $100 and AMEX takes 3.5% so we only get the difference.  We receive these processed gifts only once a month and the total the person gave is listed and only at the bottom of the sheet is the TOTAL fee listed for the month.  It is not broken down.  How can my records match the bookkeeper's records if I can't put the fee into RE?  There are too many donations to be able to calculate each person's gross donation, fee and net donation.
