I worked on something with dotnet and QB for a bit before the project got dropped. It seemed pretty easy to do without 3rd party tools. I don't remember the specifics but I think it was just a matter of calling a QB com component and telling it to spit out some XML, or sending the component XML.

If I recall correctly, it was just a matter of starting with one of the examples. Then there was a document that listed all the calls you could perform, so you just had to find the right one.

The biggest issue i've found is adding/updating QB in the right sequence, so that the validations are met. That means populating the QB data (ITEMS, CLASSES, COA CODES, CUSTOMER:JOBS, VENDORS) in the correct order and validating the existance of this data before creating/updating STATEMENTS and INVOICES and applying payments.

>I was hoping to replicate what i do when updating MSOutlook from fox and that is to store a PK value on an Outlook contact record (in a rarely used field) and simply search for that value in order to determine if an add or an update is needed. But have not found a a means of doing the same w/ QB. The version of the control i have does not support the creation of or the searching of user-defined QB fields (that may have changed though).
