title: Quick integration with SaaS application
body: <p>Customer is currently using QB Desktop for their accounting needs. They want to develop a cloud based (SaaS) business application in .NET. I have never worked with QB applications so my questions are basic.</p>
  
  <ol>
  <li>What is the shortest way I can integrate the client's QB data with cloud based MVC app ?</li>
  <li>How is the app in Intuit App Center different from QB Online app ? Can I use the QB Online right away instead of developing my own app ?</li>
  <li>If I have to develop an app ( that will available Intuit App Center), will I be able to provide all functionality that exists in QB Desktop ?  I read on Intuit site that not all functionality is available in v3.</li>
  <li>How the clients(tenants) will use this QB app ?</li>
  </ol>
  
  <p>Thanks.</p>
