# 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/freelance-invoicing-software): turn tracked hours into PDF invoices and track which are paid. - [Bookkeeping software for your LLC](https://usetimebook.com/bookkeeping-software-for-llc): Schedule-C-oriented books, bank sync via Plaid, and P&L reports. - [Self-employed accounting software](https://usetimebook.com/self-employed-accounting-software): track time, invoice from those hours, and keep Schedule-C-ready books in one app built for one person. - [Time tracking for consultants](https://usetimebook.com/time-tracking-for-consultants): capture billable hours, invoice by engagement, and keep clean books in one app. - [Time tracking for independent contractors](https://usetimebook.com/time-tracking-for-independent-contractors): log billable hours, invoice clients, and keep Schedule-C-ready books for 1099 income. ## Comparisons - [QuickBooks alternative](https://usetimebook.com/quickbooks-alternative): why a solo freelancer or single-member LLC may not need full accounting software. - [QuickBooks Self-Employed alternative for solo LLCs](https://usetimebook.com/quickbooks-self-employed-alternative-solo-llc): QBSE was discontinued — a straight comparison for one-person LLCs. - [Toggl alternative for freelancers](https://usetimebook.com/toggl-alternative-for-freelancers): a time tracker that also carries hours all the way to paid and booked. - [FreshBooks alternative](https://usetimebook.com/freshbooks-alternative): flat pricing and free time tracking vs FreshBooks' billable-client tiers and per-user fees. - [Harvest alternative](https://usetimebook.com/harvest-alternative): all-in-one that adds Schedule-C books to time tracking and invoicing — flat price, not per seat. - [Clockify alternative](https://usetimebook.com/clockify-alternative): free time tracking plus built-in invoicing and Schedule-C books, without a paid-tier jump. ## Guides - [Schedule C for a single-member LLC](https://usetimebook.com/schedule-c-for-single-member-llc): why a single-member LLC files on Schedule C of Form 1040 by default. - [Schedule C expense categories for freelancers](https://usetimebook.com/schedule-c-expense-categories): the Schedule C expense lines freelancers and single-member LLCs use, and what each covers. - [How to invoice as a freelancer](https://usetimebook.com/how-to-invoice-as-a-freelancer): step-by-step invoicing from tracked hours — what a professional invoice needs and how to get paid. - [How to do taxes as a sole proprietor](https://usetimebook.com/how-to-do-taxes-as-a-sole-proprietor): Schedule C, self-employment tax, quarterly estimated payments, and deductions, in plain English. - [Single-member LLC bookkeeping: owner draws vs. expenses](https://usetimebook.com/single-member-llc-bookkeeping): the #1 solo-LLC bookkeeping mistake and how to record each correctly. - [What is a timesheet?](https://usetimebook.com/what-is-a-timesheet): what a timesheet is, what to include, and how freelancers turn one into an invoice. - [Free profit and loss (P&L) statement template](https://usetimebook.com/profit-and-loss-statement-template): a downloadable P&L template built around Schedule C categories. ## Developers - [MCP documentation](https://usetimebook.com/docs/mcp): connect Timebook to Claude, ChatGPT, or any MCP-capable AI agent. - [npm: @squidcode/timebook](https://www.npmjs.com/package/@squidcode/timebook): the CLI and locally-runnable MCP server. - Hosted MCP endpoint: https://usetimebook.com/mcp (OAuth). ## Company - [Affiliate program](https://usetimebook.com/affiliate): earn recurring commission for referring Timebook subscribers. - [Sign up](https://usetimebook.com/register): create a free account — free time tracking, optional 14-day Pro trial, no credit card. - [Terms of Service](https://usetimebook.com/terms) - [Privacy Policy](https://usetimebook.com/privacy)
