One of the highlights is the <strong>Falteiro</strong> module: every petshop loses money to clients who book a slot and simply don't show up, leaving the schedule empty and the cash flow in the red with no warning. Falteiro automatically detects this pattern, flags repeat no-show clients, and gives the petshop the data to act, through reminders, confirmation requests or a rebooking policy. In the end, PetPredictCore isn't just a system: it's proof that whoever lived the problem up close can also build the solution, one line of code at a time.'>O sistema é estruturado em módulos: agendamento, controle financeiro, gestão de estoque e automação de processos, além de diversas outras implementações pensadas para o dia a dia do petshop.
