Hotel Manager· London, England, United Kingdom
Luxury independents and hotel groups invest heavily in Oracle Hospitality to run rooms and F&B operations. Yet in most organisations, OPERA remains a system of record - not a system of revenue.Hotel Manager converts that investment into commercial returns.Built natively within OPERA Cloud and connected directly to Simphony, it orchestrates commercial performance across the full guest lifecycle - pre-arrival, in-stay and post-departure - maintaining a persistent Oracle guest identity and linking every interaction to real-time operational workflows without middleware, manual reconciliation or third-party routing.This ensures a single commercial view of the guest from booking through departure and beyond, synchronised directly with the Oracle stack.All of this is delivered through fully branded, personalised, mobile-first guest journeys operating directly on the live OPERA profile - capturing intent before arrival, activating measurable RevPAG uplift during the stay, and ensuring every interaction reconciles against a single, persistent Oracle guest record. Every stay enriches commercial history and reduces identity fragmentation across the portfolio.We work with luxury hotels and groups running Oracle globally to activate commercial performance across their existing stack.Not a guest app.Not a bolt-on.The Oracle ecosystem finally has a native revenue layer. It's time for a change.
