I thoroughly enjoy using seSales. Its very intuitive, as one would expect on a Mac, and its otherwise easy to use. When I'm out and about visiting with customers its very easy for me to give them an estimated invoice based on current supplies, and that helps me out tremendously as a small business owner. When I'm exhibiting at fine art or craft shows, I no longer have to mail customers their receipts after the show weekend is complete. My life is much easier now. Whenever I see a fellow business owner that is also a mac user, I recommend they purchase it, and when I'm working my "day job" I always recommend it to customers, too. Great job on the software Zarra Studios, I'm impressed.
