We want to build a mobile App (internal use) for accounting purposes. With the app, users should be able to scan (and crop) invoices with their iphone camera, give them a name, add some variables (invoice date, supplier name, total amount, TVA amount,..) and upload the invoice to a folder on our web server. The entered variables should be inserted in an SQL table on the server and refer with a column "filename" to the uploaded invoice.
The app should work on Android & iOS and can be hosted on our server (but that's not required).
We will create the mockups (how it should look like), and a full detailed briefing. In your application, please describe briefly how you will create this (what software/..)
