Configuring Opportunity Settings in Vome
How to access these settings:
What an approved user can do on their own: see the shifts, reserve them, cancel them, and how many they can take. Also Flexible Schedule, Instant Book, and everything to do with shift requests.
What are the User reservation settings on an opportunity?
Which shifts users can see and when the door is open: hiding full shifts, the visibility window, the reservation cutoff, pausing reservations, overlaps, and scheduling when the reservation portal opens.
What are the Scheduling controls on an opportunity?
Whether users can commit to a whole recurring schedule in one step instead of reserving shift by shift, whether they can leave it, and how long the commitment lasts.
What are the Shift series settings on an opportunity?
How attendance gets recorded: check-in and check-out availability, tap-to-check-in, GPS proximity validation, auto check-in/out, and when the check-in and check-out portals are open.
What are the Attendance tracking settings on an opportunity?
Who can claim hours, whether claims are auto-approved, additional hours on top of a logged shift, and what you collect with a claim through a form or a note.
What are the Hour claim settings on an opportunity?

None of these settings restrict administrators. You can always reserve, assign, record attendance and log hours on someone's behalf.
They are per opportunity, so two opportunities can run completely different rules.
Custom scheduling, attendance and claim settings need the Pro, Enterprise or Ultimate plan. Receiving hour claims works on every plan.
