Why not run a DJ guest list in a spreadsheet?
Sheets are fine for a one-off. They fail when the door, RSVPs, and three promoters all need the same names.
A spreadsheet is fast to start. It has no door view, no guest RSVP, and no history tied to a night. Version conflicts show up as people who swear they were on the list.
DJZop makes the night the source of truth. RSVPs, door check-in, and the artist site read the same list. You can still export if you want a sheet for accounting.
Stay on a sheet if you throw one party a year with a single editor. Move off it when a second promoter or a real door shift appears.
