I love that it is so easy to set up for my clients! It's very user friendly which makes things go smoothly when we are transporting their dogs or cats from one city/location in another state of country etc.. There really isn't anything bad about this software at all!! We've transported pets internationally with them as well - no issues there either. The only thing you have to watch out if your client has allergies because they may think something was put into his food but its not (which happens sometimes). If he does then just tell him what happened instead saying "I don’t know". That way everything will be ok :) You can also easily customize how much each item costs depending upon where exactly doggy daycare facility / veterinary clinic located within different cities throughout US & Canada too ;) Great product overall. ! And best part? They offer free training sessions via phone + email support whenever needed.
