The best program you can get is Auction Maesto - maestrosoft.com/auction/index.html
I'm a full time Charity Auctioneer | Fundraising Auctioneer and it is the software that I recommend to my clients across the board. It is most comprehensive and can be used for all events. Pricing is very reasonable too. It is a one time investment and your school owns the software forever.

They offer free demos - ask for one and check it out for yourself.

Does anyone use a computer program to track donations for an auction? We are looking for something that multiple people can access and change. We need to put in company names, donation item, if it was picked up and contact info.
