Here is the "tentative" scope for 3rd Party POS with Opera cloud "Oracle Hospitality" integration:
1. Retrieve Customer data from Opera and customer occupancy (validation) /update customer details
2. Post 3rd Party POS charges to rooms in Opera "Oracle Hospitality"
3. Different charge by type of item/ different charge types from the 3rd Party POS to Opera "Oracle Hospitality"
4. Please add from you experience what other requirements might be needed and let us know the estimation accordingly.
Please provide: the cost of such integration (up to 10 integration points between the 3rd Party POS) and the timeframe of this project, based on this high-level scope.
