A hotel restaurant runs like a business within a business. To the guest, though, it’s simply part of the hotel.
A guest charges dinner to the room. A drink is posted from the bar. A transaction is voided. Each of these depends on two operational systems staying aligned. When they do, the guest never notices. When they don’t, the problem shows up at checkout.
Many hotels assume that activating an integration means it’s ready. It isn’t. Both systems need to be configured, mappings completed, and real scenarios tested. You also need a plan for what happens when something changes tomorrow.
