A hotel runs on people you are not standing next to. The question is never "can I trust them" — it is "what can each one reach, and what did they actually do".
Not a setting you have to configure hotel by hotel. A receptionist opens the system and the screens that are not his are not there — not greyed out, not there.
The rule is enforced on the server, not by hiding buttons. A screen somebody is not allowed to open does not load even if he knows the address.
Days present, leave, overtime and advances become the month's payslip without anybody retyping a register into Excel. Each person can open their own — and only their own.
Assign work to a person or a role. The screen shows what was given, what got done, and what is still open at the end of the shift — so a handover is a screen, not a conversation someone forgot.
Every rate change, every discount, every refund, every room block, every login — who, what, when, and from where.
Waiting for approval, waiting to be paid, already sent — each with who asked and who allowed it.
Maintenance wants a room off sale. It waits for a manager, and the request and the answer are both kept.
Allowed, with a reason — and every one appears on your screen with the name of whoever wrote it.
A correction to a booking or a bill goes through a request, not a quiet edit.
Count the drawer, bank the cash, lock the sheet. After that the day cannot be edited.
The moment someone is let go, every login and every phone of theirs stops the same second.
