While I appreciate all of the work the guys at Virtuemart have done over the years, their shopping cart product still does not support one the Internets most recent must have items – Destination-based sales tax based on local zip code + 4. I have been working on a website for a company in Washington using Joomla 1.5.x and Virtuemart 1.1.x. Unfortunately I was almost finished the site, just for a new law to go into affect, which affects many States now, and that is the new Destination-based sales tax law. This has thrown a major glitch into our time lines and development. Now my company has taken a huge financial hit because Virtuemart does not support this, nor do they seem interested in building this feature into the site any time soon. There isn’t much help or any relevant contributions in the Virtuemart forums either. There have been a few suggestions for older versions of Joomla/Virtuemart and you can find one here: http://forum.virtuemart.net/index.php?topic=22809.0, however nothing real solid for newer versions. This post is just an FYI for anyone looking to use Virtuemart, as they don’t support this extremely important feature.
