I am not currently using Sourcelink. 

Back when QB had the scanning feature originally, they were charging for it, so I used Sourcelink as it was more economical. 

After a while QB Included Scanning with the Enterprise edition at no charge, so I switched to that...everyone in the office learned it, it's a simple learning curve. I found their customer service to be awesome.

What I am doing now is sticking with QB Enterprise 21 and not upgrading, waiting for that email that says "we will no longer support version 21 we all know that's inevitable.

See if they have a trial version and it works for you? I think they do have a 14 day trial version.
