It is a lightweight framework for recording trip basics, budget assumptions, owners, deadlines, split rules, and fallback plans in one visible place before departure.
It is not a booking service, payment processor, visa checker, or full project-management system. It helps the group make responsibilities and decisions explicit; bookings, official checks, and settlement still happen through the relevant external services.
Every important decision or booking should have one named owner and a clear due date. Smaller optional tasks can stay flexible, but flights, accommodation, documents, payments, and arrival logistics should not be left floating.
Choose a fallback when the task is assigned. If the deadline passes, the group can use the backup option, move ownership, or deliberately drop the item instead of restarting the same discussion under time pressure.
Use the trip budget calculator to set a planning baseline and the free expense splitter to calculate actual balances. When a document becomes hard to keep current, move shared tasks and trip updates into the NomadCrew iPhone app; Android remains in closed testing.
