## Overview

SaciGestao is a WPF desktop real-estate management system. The main workflow is to sign in, manage clients and property listings, create rental or sale contracts, and review portfolio activity on the dashboard; contracts can also be exported as PDFs. Data is held in memory during a session and written to JSON on exit. The README describes financial management as not yet implemented, although finance-related source modules are present. Relationships below are limited to README statements and indexed or excerpted source references.

Main entry points: [`SaciGestao/MainWindow.xaml.cs`](https://github.com/miguelsignorini/projeto_acelera/blob/main/SaciGestao/MainWindow.xaml.cs) (Main navigation), [`SaciGestao/Service/FinanceiroService.cs`](https://github.com/miguelsignorini/projeto_acelera/blob/main/SaciGestao/Service/FinanceiroService.cs) (Payment tracking), [`SaciGestao/Service/ContratoService.cs`](https://github.com/miguelsignorini/projeto_acelera/blob/main/SaciGestao/Service/ContratoService.cs) (Contract rules), [`SaciGestao/Service/Persistencia.cs`](https://github.com/miguelsignorini/projeto_acelera/blob/main/SaciGestao/Service/Persistencia.cs) (JSON persistence)
