Timebook is time tracking, invoicing, and bookkeeping in one app - built for one freelancer, not a team of 50. Start a timer, send a polished PDF invoice, watch the bank payment land, and let it auto-categorize for tax season. Connect your bank via Plaid, import statements, or log time from the CLI or ChatGPT (MCP). $29.99/mo flat. No per-seat, no tiers, no upsells. 14-day trial.
