Invoicing & QB integration System (Webbased)

I have a bookkeeping company and have a need for a webbased system that will integrate (or download into) with my clients existing quickbooks file. Phase 1 = release of $150.00 (this needs to be completed in a few days) -Webbased secure dashboard that uses icons (similar to Quickbooks).? For this phase the only function needed will be invoice.? For this phase we will need a secure login created and the invoice functionality. -Webbased secure login environment that enables clients to input information into fields and generate a pdf invoice. -The options for the invoice should including printing immediately or having it emailed, in addition it should be: ? 1.) Simple to use. ? 2.) Secure Admin section plus Client login section. ? 3.) Add as many clients as needed. ? 4.) Add as many invoices for each customer as needed. ? 5.) Invoices self total the inputted data. ? 6.) You can search through customers or invoices for keywords. ? 7.) Keeps track of Payments you receive from customers. ? ? 9.) You or client can create a clean invoice for printing. 10.) Unlimited? Items per Invoice plus misc., shipping etc... *Should have the same functionality as:? <[login to view URL]> (sign-up for a free acct, to know how it should look) And same graphical content as the above. Phase 2 - release of $50 (Data downloads into QB) the invoice data should download into QB, the admin should have the ability to download the info generated into their company quickbooks file versus 2008 or greater. *Please note that the deadline set is only for phase 1, I will work with the coder to identify a deadline for phase 2
