It's very easy to use - even for someone who isn't tech savvy! The interface makes it so I can see everything at once in one place without having to scroll through pages of text or images. There are many features like being able to add multiple dogs/cats into your account (you don't have to be an existing client) as well as adding clients directly from other programs such as Outlook and Excel. You also get to keep all previous invoices which helps ease any confusion about what has been paid already. If there was anything we didn't really enjoy using this program they've changed recently-it used to work great but now some functions are slower than before when loading screens would appear after clicking something several times. We love how organized our kennels are thanks to this tool.
