# Adopets > Adopets is an Adoption Management System (AMS) for animal shelters and rescues that streamlines the adoption process end to end — applications, team collaboration, digital kennel cards, secure payment processing (adoption fees, licenses, products, donations), reporting, and post-adoption communication.
