Giving campaigns give you a page built around a goal, with progress that updates as gifts come in. Point supporters to one link for a renovation fund, a season push, or a one-time ask, and let them see the campaign move.
Because campaign giving runs through the same system as your ticket sales, every gift lands in the same CRM as your patrons. You see who gave, what they gave to, and how close you are to the goal without keeping a separate spreadsheet.
