With this lightweight application, you can manage almost all financial aspects of your construction projects. Define your projects, register the parties involved (such as clients, contractors, and material suppliers), record your incomes and expenses, and store your invoices.
The key feature of this app is that all information is stored only on your phone or computer (no cloud storage). Finally, with various filters, you can view  detailed reports of your costs, incomes, and debts based on your desired date range.
