As a website developer that works with wordpress / Joomla / Virtuemart - response time is important to me. Myself and several others have been waiting forever on a developer for Quickbooks integration with Virtuemart 2.0.12 - this product costs close to $1k and they can't be bothered.
Giang at Joom Donation is on top of his game and charges a reasonable price to solve an annoying problem.
I found the plugin to be at most 15min of time to install. It works and my client is happy!
Thank you Giang! Keep up the good work!
