If you are using QuickBooks Online, this blog post from the QuickBooks Online group about their software and the various browsers is a must read for you.
Before you forge ahead and automatically upgrade or change browsers based on their recommendations, be sure to read through the growing number of comments at the bottom of the blog post. There you will see some feedback and real-life experiences of those who did just that.
Since I don't work much with the Online version in my practice and focus on the Pro, Premier and Enterprise Editions of QuickBooks, I welcome your feedback on how the Online edition is working out for your business. Post your thoughts in the comment box below.
