Timebook — Time tracking, invoicing & bookkeeping for freelancers & solo LLCs

# Timebook > Timebook is an all-in-one web app for freelancers and single-member LLCs that combines time tracking, invoicing, and bookkeeping in one tool. Time tracking (web, CLI, or an AI agent over MCP) is free forever, no credit card. A Pro subscription — $29.99/month — adds PDF invoicing, Plaid bank sync to categorize transactions and match deposits to invoices, Schedule-C-ready books, and subcontractor billing (bring on subcontractors who track hours free, and invoice their work to your clients); new accounts can start a one-time 14-day Pro trial with no card. ## Key facts - Pricing: free forever for time tracking + CLI/MCP. Pro is $29.99/month (no per-seat, no tiers) and adds invoicing, bank sync, bookkeeping, and subcontractor billing. One-time 14-day Pro trial, no credit card. - Subcontractors (Pro): add a subcontractor to a project by email — you set their hourly pay rate. They track hours free (being a subcontractor is on the free tier), and you invoice their work to your clients. Not-yet-registered invitees get an email invite that links automatically when they sign up. - Built for: solo freelancers, contractors, and single-member LLCs in the US — not teams or accounting firms. - Core loop: track time → invoice from those hours → get paid → reconcile in Schedule-C-ready books. - Bank sync: connect via Plaid, categorize transactions to Schedule C lines, and match incoming deposits to the invoices they paid. - AI / developer access: a CLI (`@squidcode/timebook` on npm) and a hosted MCP server at https://usetimebook.com/mcp; also available as a ChatGPT app. - Made by Squidcode LLC (https://squidcode.com). ## Product - [Timebook home](https://usetimebook.com/): time tracking, invoicing & bookkeeping for freelancers and solo LLCs. - [Time tracking for freelancers](https://usetimebook.com/time-tracking-for-freelancers): track billable hours from the web, CLI, or an AI agent via MCP. - [Freelance invoicing software](https://usetimebook.com/freel
