What Tuttle is

Tuttle is a free desktop app for solo freelancers that brings time tracking, invoicing, tax planning, client management, and business finances into one place. It runs on Linux, macOS, and Windows. Users can track project time, enter it manually, or import it from a calendar or time-tracking tool. Tuttle can turn tracked time, manual quantities, or fixed-price contracts into invoices and timesheets, including deposit and final invoices. Invoices use Factur-X / ZUGFeRD formats, with optional XRechnung, and can be exported to PDF or emailed. Its dashboard covers revenue, unpaid invoices, project budgets, forecasts, and progress toward financial goals. Tuttle also tracks VAT and income-tax reserves and expenses, and estimates monthly pay users can safely take. It can extract invoice and contract details from PDFs using a local Ollama model or an OpenAI-compatible provider. Client, contract, time, and invoice data is stored locally. The project is open source under the GNU General Public License v3.0.
