Where to start with QuickBooks development? [closed]

Answer 1

For the new QuickBooks Online API, use http://qbapi.com

Answer 2

Yes it provides SDK using which you can integrate your application with Quick Books http://qbsdk.developer.intuit.com/sdk/qb/Get_Oriented

Answer 3

Take a look at Quickbooks SDK and Documentation. The SDK has two COM interface: QBFC and QBXML. The difference in using QBXML, you need to serialize and deserialize XML manually which isn't hard once you get the handle of it. And I find QBXML much more convenient since you can choose to include requests and responses you need.

Also, if you plan to use Quickbooks SDK, the Online Reference is your best friend.

Answer 4

The Intuit Developer Network (IDN) is the starting point for learning about QuickBooks integration. For .NET developers, there are 2 directions you could go:

1. Join the Front Runner program - this is a partnership between Intuit and Microsoft to assist .NET developers who want to develop cloud based services using the Intuit Partner Platform (IPP). The IPP is a hosted cloud based development platform, and is generally regarded as the way of the future for QuickBooks integration. IPP has not up to now been that friendly to the Microsoft technology stack; so-called native IPP apps run in Flash and Java.

2. Use the traditional QuickBooks SDK with the QBFC framework. This method of integration is time tested and it is simpler, especially if you are only interested in custom development. The SDK has always been eaiser to use with .NET and C#, although many developers have done well with Java, PHP, and other languages despite the difficulties.

There are plenty of online and downloadable resources for both these approaches available at the IDN site. You won't find any books or classes on QuickBooks development, though - it's a niche area.
