Hi,
from your description, it seems you would like to develop a competitor of Xero or Tally. Several aspects are pushing me to ask you the following :
1) Every country is having their own taxation rules and performance calculator. Who shall give us those information ?
2) you want to save the Client in your local machine. This possible only with a desktop based software. But you want a web based, am I right ?
3) The budget mentioned is not at all acceptable because it will be covering more than Farm & Crop Accounts, Bonus/Penalty Calculator, Accounts payables / Receivables, GL, EDI Feed Capture, Integrated Sales & Purchase ledgers, Tax and performance calculator etc.
Are you fixed with this budget ?
Lastly, one can not drink even a cup of tea with 30 dollars and that too in paypal. Come on. We never accept project below 30% advance. If you agree, only then respond to my message.
Regards,
Mit-
