FreelanceDesk is an offline invoicing and client tracker that ships as a single HTML file.

You download it, double-click it, and it runs in the browser you already have - Chrome, Edge, Safari or Firefox - with the internet switched off. Your client list, your hours and your invoices never leave your computer: no server, no account, no usage tracking.

There is no subscription to fund, so you pay once and keep it. If you ever decide to move on, one click exports everything to CSV or a full JSON backup.
