I love how easy it was to use, my clients loved that they could add their own notes as well! The customer service has been great so far with any problems we have had. Sometimes you can't do anything right away in the app but they are working hard to get features added soon. It's an amazing program! We haven't found too many things that don't work yet. Just make sure everyone knows what buttons to push before you start using this tool. You will be glad you did! Keeping track of invoices and billing customers easier than ever.
