There is a company that has software that does post directly into QB. Go to Personable.com/sourcelink/ and look at sourcelink standard, they also have a sourcelink management as well with additional features. It either has a demo you can watch or you can set one up with the company.  The only downside I see is that if you have multiple companies in QB, when scanning you have to close out of one company to be able to  scan to the company you are working in.
