QuicksBooks Import Items & Invoices - quickbooks

Question

I have QuickBooks 2010 pro edition, As the Title suggests I need to import Products & Invoices into Quickbooks.
Some Background...
we are an online company where we sell products online, my client wants to import all products into quickbooks and every online sale into quickbooks as well, our website is built using ASP.NET with SQL Server as backed.
I am new to quickbooks, so i am not sure what to do from here...
I have heard of IIF import & SDK, unfortunately I could not find and valuable documentation on them. can anyone please put me in right direction (maybe some sample code)? please do not give me SDK url of quickbooks website.
Thanks

If you're not willing to look at the QuickBooks SDK, you are doing yourself a huge disservice.
The easiest way to implement what you're trying to do is via the SDK and the Web Connector. There's a basic overview of the QuickBooks Web Connector on our wiki. It's specifically geared towards moving data from an online website, into QuickBooks for Windows (just like you're trying to do). The basic idea is that it polls your website, asking for stuff to do, and you can feed it XML requests to do stuff (add a customer, add an invoice, etc.).
Basic protocol looks like this:
// Web Connector asks your SOAP service to authenticate Web Connector
=> SOAP server: authenticate with the username "xyz" and the password "bla" (authenticate)
If authentication is successful, the SOAP server returns a ticket value and the process continues
// Web Connector asks for something to do Web Connector => SOAP
server: hey SOAP server, what do you have for me to do?
(sendRequestXML)
SOAP server generates and returns a qbXML request
// Web Connector relays that request to QuickBooks, and receives a
response from QuickBooks Web Connector => QuickBooks: hey
QuickBooks, the SOAP server gave me this request, can you please
process it?
QuickBooks processes the request, and returns a response to the Web Connector
// Web Connector relays the response from QuickBooks back to the SOAP
server Web Connector => SOAP server: hey SOAP server, here is the
response for that last request from QuickBooks (receiveResponseXML)
SOAP server processes the response, handling any errors and doing whatever with the response
SOAP server returns a percentage done, if it's less than 100%, this process continues...
// The process starts over, with the Web Connector asking the SOAP
server for the next request... Web Connector => SOAP server: hey
SOAP server, what else do you have for me to do? (sendRequestXML)
SOAP server generates and returns a qbXML request
... and so on and so forth ...
If you download the QuickBooks SDK (ouch, sorry!) you'll find that it contains some of the stuff you've asked for. Specifically, there is sample code it drops in this directory:
C:\Program Files (x86)\Intuit\IDN\QBSDK12.0\samples\qbdt\c-sharp\qbXML\WCWebService
Here's a cleaned up, stripped down version of what's in that sample code:

The QuickBooks SDK also contains a 98 page Web Connector documentation PDF which describes implementation in detail, and 600 pages of general QuickBooks SDK documentation which might be helpful.
