New Invoicing System

Because of recent change in our pricing structure, we need a new invoicing application on our website. Our current invoicing system on our website works only with fix pricing. On our website we provides Sales lead to our suppliers and we want to charge variable pricing for variable number of leads they received in a month, e.g. if they received up to 10 leads in a month then we charge $0.00, if they received 100 leads = then $1 per lead , and if they receive 200 leads = then $.90. We also have Fix Joining Fee of $99, but some time we offer free joining too as a promotion. We want the Invoices to be calculating automatically and to be sent monthly to our clients both to their email address and their USER Accounts Area on our website. Our Clients mostly pay us by Internet Banking and Direct Bank Deposit, So we want a system from where we can upload our Bank Statement in CSV format and it will automatically credit the user accounts. We also want to do Manual entries (For Cheque or other method like cash). We want to accept Credit Cards Payments from our clients through Paypal and integrate with our Paypal account. We also want to integrate Taxes/GSTs and Paypal fee (same way GAF calculate Paypal fee and add to the final payment). We want each Supplier can see and use in their Admin Area the following: 1- Inv # 2- Fee Amount 3- Paid Amount (Last deposit they made) 4- Due Amount (Current Bill) 5- Balance Amount (Can be negative or positive) 6- Bill Date 7- Due Date ( If the due date is passed and the balance is negative then the account will be automatically suspend and suspension email will sent to the supplier)". 8- Option ( View/Print , Pay ), when they click Pay they will see our bank account details for deposit or if they like to pay by credit card then they will have Paypal option. Don't put Fake Bids, you can ask questions before you bid. Please no time waster, if you think you can do this in a timely manner and with in the budget then bid. Happy biding!!! We will do more business with the winner …..
