It has been a while since I posted but wanted to share some exciting news about PetSitClick. Over the winter we have been hard at work making PetSitClick the easiest to use and best pet sitting software out there. On the administrative side of things we have introduced a ton of new improvements including the ability to copy visits, mark multiple invoices as paid and much more powerful invoicing tools. Coming up, we are introducing a complete redesign of our customer portal at the end of April and apps for your walkers and sitters later in the Spring.
