De Bortoli Travel app for iPhone and iPad

The purpose of management is to create supply and demand. On the one hand there are providers such as parking lots, etc. Offering parking, tours in Venice, on the other there are commercial activities (hotels, newsstands, etc.) that offer these services to their customers.
De Bortoli Traver stipulates agreements with the various parking lots, tour operators and makes these products available to all the activities involved in the sale.
For each transaction the activity accumulates a predetermined percentage with De Bortoli Travel which will be recognized at the end of the month.
The management system must be able to know both the number of transactions and the actual total of transactions and the actual amount that De Bortoli must subsequently pay to the operator.
