For the past couple of months, I have been getting this error when trying to check account activity with Billing Solutions, which opens up in a browser within QuickBooks:

QuickBooks Billing Solutions isn't currently available through the web browser you're using. In time, we hope to support all browsers to avoid this inconvenience.

For now, we hope you'll take the time to download a browser that does allow you to use QuickBooks Billing Solutions. We think you'll find that your time was well spent. You can download Microsoft Internet Explorer at

Thank you and sorry for the inconvenience.

I'm using QuickBooks Enterprise Solutions 13.0 release R8 and Internet Explorer 10 (latest version). After submitting bug reports several times when this started, I finally decided to give them a call today. It turns out that they are finally aware of the problem, although there is NO KB listed neither in the above error message or on any of Intuit's web sites. 

Apparently, the cause of the problem is that the latest release of QuickBooks (R8) is not compatible with IE 10. Unfortunately, the only current solution is to not only remove IE 10 and install IE 8 instead, but you also have to downgrade QuickBooks to the R6 release. That means a lot of uninstalling and reinstalling. NO THANK YOU! I will just wait until they have a fix in an upcoming release (hopefully, there will even be one!).

I just feel sorry for those users of Billing Solutions that are actually paying for it, unless they are getting it for free during this time. Otherwise, it would be very unfair to be required to downgrade just because Intuit made the problem in the first place.
