Live music, booked right.
Venues post their open nights, artists book them — contracts and payment handled.
Most rooms book the same ten or twenty acts for nine nights out of ten. GigsFill doesn’t change who you book — it stops you doing it by text/email and no more need for your crazy spreadsheet.
Put those acts on your Preferred list. Post the nights you need covered. They book themselves — and the contract and the payment take care of themselves too.
You decide who is on the list, how often each act can play, and what they are paid. Nobody else gets near your calendar unless you open the night up.
