Android App for managing ledger of my clients in business

I need an app for managing ledger of my clients. App: 1. Enter CUSTOMER's NAME 2. Click on CUSTOMER NAME and add his transaction whether credit or debit. 3. While adding transaction there should be an option of 'click image of the bill'. 4. After clicking the image ek EDIT ki option aani chahiye (only orientation editing and cropping) 5. INDEX kind of a page jahan pe saare customers k naam with their balance amount. 6. SEARCH option for point no. 5 7. Click on a customer's name from that list there I'll find 3 columns: a. Credit b. Debit c. Balance 8. In these 3 columns there should be all his TRANSACTION DETAILS along with the images clicked during the transaction. 9. DOWNLOAD PDF option for point number 5. While downloading there should be a switch ON-OFF. If its ON PDF will be downloaded with customer's name and upto date balance. If its OFF then PDF with name only. There should be another switch ON OFF for those accounts whose balance are NIL. When its ON customer's whose balance are NIL should be excluded otherwise included. 10. When I open a ledger of particular customer and download it in PDF, along with each transaction a readable image should be there, So that i can give its printout to the customer. 11. EVERYDAY LEDGER page, WEEKLY LEDGER page and MONTHLY LEDGER page. Along with the transactions, IMAGE should also be there. 12. Admin login: access to the full app 13. Employee login: access only to the name database and adding a transaction. 14. All this data should be secure so that even a top IT PROFESSIONAL could not trace my admin account.
