We'll develop a user friendly iPhone application which will be working as per your mentioned requirements. We'll integrate banking API and JavaScript API of Tableu.
The app will notify if payments are missed and made, etc. Additional features like Credit repair, aid customers, etc. will also be integrated perfectly within this app. You can really be assured of that.
We'll develop an easy to use ADMIN PANEL whereby you'll be able to manage/update the payments, credits, tools, images, etc. Web services will also be created accordingly. Data will be stored in latest MySQL 5.X databse in an organised way.
Finally, upon completion we'll assist you to launch the app on iTunes store and provide you 6 months of free Support.
But I believe there are some more points that are needed to be integrated within the app. So please provide us more details.
Thanks you
Warm regards
Rob Parker
