Never promise the same sponsor spot twice.
See every upcoming issue in one place. Reserve a spot while a sponsor decides, confirm it when they say yes, and automatically free it again if they do not.

No more double-booking.
Everyone sees the same sponsor status, so two people cannot accidentally sell the same issue.
No forgotten “maybes.”
Reserve a spot while a sponsor decides. If they do not confirm in time, it opens up again automatically.
Always know what happens next.
Move each sponsor from available to reserved, booked, ready, and published in a clear order.
