It was easy for us as we have been using vetit since it's inception 15 years ago! The user interface has improved vastly over time but in general I don't dislike any part of this product; however there are some areas where they could improve - such as faster file uploads when sending documents across from one patient or owner (or other providers) files into their own private folder so those people can access them without having an account with our office software first!! This makes sharing information much easier between all parties involved instead of waiting days if not weeks before getting responses back about shared communications/documents etc.. Also being able to send emails directly through the app would be very helpful too especially given how many times clients forget passwords at work nowdays! We also use both apps together which works well because the two programs sync up nicely allowing me easily transfer data from patients who see.
