## Overview

Credit HP is a Laravel/Filament application for managing phone-installment contracts and monitoring collections, capital, and profit. Operators manage customers, products, guarantors, contracts, and payments; installment schedules and payment status feed the monitoring matrix and overdue views. The README documents WhatsApp reminders through Evolution API, with a Fonnte fallback visible in the sampled service. The graph reflects documented capabilities and sampled service behavior; unsampled resource and widget wiring is not inferred.
