What Tuttle is
Tuttle is a free, open-source desktop application for solo freelancers managing time, invoices, taxes, clients, and business finances. It runs on Linux, macOS, and Windows, and stores client, contract, time, and invoice data locally. Time can be captured with a project timer, entered manually, or imported from a calendar or time-tracking tool. Tuttle creates invoices and timesheets from tracked time, manual quantities, or fixed-price contracts, including deposit and final invoices. Factur-X and ZUGFeRD e-invoices can be exported to PDF or emailed, with XRechnung optional. The dashboard shows revenue, outstanding invoices, project budgets, forecasts, and progress toward financial goals. It tracks VAT and income-tax reserves, expenses, and estimated monthly pay. PDF invoice and contract data can be extracted through local Ollama or an OpenAI-compatible provider. The project uses the GNU General Public License v3.0.
