Iris is easy to use for anyone who does not have much experience with computer systems or software. The layout of the program can be confusing at first but once you get used to it its very user friendly! I do like that there are several different ways to enter orders into Iris. We also love how quick we receive our invoices after shipping an order. There really isn't anything i dislike about this system other than maybe being able to print out one invoice instead of having to go back to each store when printing multiple invoices. Iris has made managing my stores so much easier and faster since implementing Iris in all 3 locations.
