I have an idea for a mobile/web app that I would like to make, and I am trying to find out what is the simplest, most efficient and user friendly way to develop and troubleshot this application.
What I want this app to do:
Mobile (Customer) Android/ iPhone Friendly
- View Invoices
- Take payments - Bank/Recurring (auto on/off options), Credit/Debit Card (immediate rejection if insufficient funds) and Cash.
- Receive Notifications ( Payments are due)
- Make personal updates
- Billing and Collections
- Send detail payment information to customers minus credits.
Any and all suggestions are greatly appreciated.
