I like it the best is how it can be connected to all social media, and how it automatically saves and resizes photos. I also think the way you can share your schedule with a client. I don't think there are anything I dislike about it. There is only one version. I think this is useful because you can schedule someone who you only know from social media. It is useful if you have a lot of clients. That way, you don't have to contact them to see if they are available. It's easy to use, it's easy to communicate with clients and it's easy to pay our employees. I wish it was a little more user friendly for our clients. It would be nice if they could search by city or neighborhood, or even block by block. Also being able to send out invoices with attachments would be handy. Professional Pet Sitter has helped us streamline our pet sitting business, and we can easily communicate with clients.
