The Open Auction is an excel spreadsheet, specifically designed to help you plan and execute your auction. It has been created with non-profit organizations in mind. Its only requirement is MS Excel. The Open Auction consists of several worksheets; each one designed to manage a different part of the auction process. The system helps with the following areas: manage vendors and their donations; manage attendees and paddle numbers. It records bids on live auction items and records bids on silent auction items. It also manages raffle items, 50/50 draws, and cash donations; generates invoices for checkout; controls expenses; generates auction items lists and silent auction bid forms; generates thank you letters with results from the auction.
