A band-booking platform could help customers discover acts by style, location and occasion, then discuss a suitable performance. The first commercial decision is whether the platform introduces people, manages bookings or acts as the contracting party.
Profiles would need approved media, line-up information and a clear description of what a performance includes. Availability can be provisional until travel, timings and requirements have been checked. An enquiry should not appear as a confirmed booking simply because a date looks free.
Start with one type of event and a small group of acts. Map enquiries, quotations, deposits and cancellations. Decide who resolves disagreements and how changes are recorded, so both parties can see the arrangement they actually accepted.
