Freelancer Toolbox is a browser-based collection of free invoicing, rate, tax, and contract tools for freelancers, plus paid document templates and open-source command-line utilities, published at kleogeos.github.io/freelancer-tools.
What is Freelancer Toolbox?
Freelancer Toolbox is a set of free web tools that run entirely in the browser with no signup or account. It takes form inputs—client details, amounts, wallet addresses, or pasted contract text—and outputs printable/PDF invoices, crypto payment QR codes, CSV tax records, hourly rates, late fee calculations, and clause checklists. The site also sells paid templates (Freelancer Starter Kit, 40 AI Prompts for Freelancers, Web Developer Pack, and a bundle) and provides open-source CLI tools installable via pip. It is made by kleogeos on GitHub.
Key Features
- Invoice generator — fill a form and get a clean printable/PDF invoice in under a minute.
- Crypto invoice generator — same invoice plus a built-in scan-to-pay QR code for USDT/BTC wallet addresses.
- Live crypto network fee comparison — real-time USDT transfer cost on TRC20 vs ERC20 vs BEP20, fetched from public blockchain nodes.
- Crypto income tax helper — looks up the historical USD value of each crypto payment received for income tax record-keeping and exports to CSV.
- Hourly rate calculator — turns a target yearly income into an hourly rate that covers taxes, time off, and non-billable work.

- Self-employment tax estimator (US) — rough estimate of what to set aside for taxes before spending an invoice payment.
- Contract checklist scanner — paste a contract and instantly see which of 10 standard freelance-protection clauses are missing.
- Open-source CLI tools — pip-installable commands for invoice generation, contract checking (including a pre-commit hook), rate calculation, and checking USDT TRC20 payments without an API key.

What can you do with Freelancer Toolbox?
- Freelance designers and writers: create a printable PDF invoice in under a minute by filling a form, then email it to a client without creating an account.
- Crypto-paid contractors: generate an invoice with a scan-to-pay QR code for USDT or BTC, and check the current TRC20 vs ERC20 vs BEP20 transfer fee before asking for payment.
- Self-employed workers in the US: estimate self-employment tax on an incoming payment and calculate a late fee if a client pays after the due date.
- Developers: install the freelance-invoice-cli via pip to generate HTML invoices from a JSON file, or wire contract-checklist-cli into a pre-commit hook to catch missing contract clauses before signing.
