# Sponsor Concepts
An event Sponsor is a commonly used term for a Donor that is also wanting to participate in the event as a bidder and potentially receive recognition for their contribution to the event.
Although Sponsors and Donors are essentially synonymous, if the Sponsor wants to participate in the event by being able to bid on items, for example, they will also need to have a Bidder Record.
Donors and Bidders are considered two separate entities in Auctria.
# Sponsors And Donors
A key difference between a Sponsor and a Donor is the Sponsor generally is making their donation and receiving something in return. For example, this may be special placement or promotional consideration on the Auction Website, Tickets to the event, or some type of For Sale item.
To accept a Sponsor via your Auction Website, they must purchase an item.
See Selling Sponsorships for more information on this.
A Donor, on the other hand, would often be making a "cash" donation or providing an item or service to the event to help raise funds or offset costs; and, although they may potentially receive recognition on the Auction Website they are not "purchasing" anything with their donation.
A Donation can be designated as a Sponsorship (this is no longer recommended) and must be done using the Add A Donor Donation function to manually accept the donation.
