Westernmass - we are a private Christian PS - 8th grade school in Missouri. I designed a simple spreadsheet for use in tracking (prior to my first auction, we kept notes in a file folder). Spreadsheet has these columns: Contacted Y/N, Donor, Contact Name (have very few), how contacted, date, whether they responded, whether they donated, when the donation was received, and notes. The final column is whether to contact them again next year. Each year, I filter by the "contact again next year" column and that becomes the basis of the next round of requests. In the notes column on this tab, I put deadlines for the business if known.
On another tab, we list donation, donor, value, received Y/N, thank you note Y/N, and notes.
We've used spreadsheet applications in the cloud, but most people send me the businesses they contact and the results and I update and send out our master spreadsheet periodically. We only have 3 people who do most of the work on this, though, or we'd probably move everything to the cloud.
We can't request donations from breweries, wineries, or casinos - we have lots of them in this area.
Good luck on your event next week!
