I suggest a really exciting market would be the Corporate Travel Market. In order to attract large Corporates for mass adoption I suggest the following 5 features would be advantageous.
- Auto Expense Processing features - either using the phone camera to auto log receipts and invoices
- Exporting Expense items
- Expense Analytics Reporting - tracking periods of high/low activity, with location, time etc aimed for Management
- Points Rewards System - for strategic preferred hotels, airlines, city travel, restaurants etc.
