I love the simplicity and convenience of Harvest. I track my time and expenses as I am on the move, which makes for easy billing. I wasnt thrilled with a monthly subscription fee, but it is worth every cent as I am able to accurately record my time on my mobile device. I cant imagine going back to my old manual system. I recommend it for small business.
