What InvoiceTools is
A free invoice generator and a set of business calculators that run entirely in your browser. Build an invoice, write a quote, work out a margin or a late fee, and export a print-ready PDF, without an account and without anything you type being sent anywhere unless you choose to. InvoiceTools.com is built and run by one tradesperson in Houston, Texas, as Invoice Tools Inc.
Why it works this way
Most free invoice generators are a funnel. You fill in your client's details, their address, what you charged them, and all of it lands in a database belonging to a company you had not heard of an hour earlier. The invoice is free; your billing history is the price.
These tools do the arithmetic and the layout on your own device. Used without an account, there is no upload step, so there is nothing to store, nothing to leak, and nothing to sell. Close the tab and it is gone. Three things do send data, and only when you use them: saving to an account, sending a document as a tracked link, and AI drafting, which sends what you give it to be read. The privacy policy sets out each one.
It also means no watermark, no three-invoices-a-month limit, and no email address demanded before you can download the thing you just made.
Who uses it
- Freelancers and consultants who invoice a handful of clients and want it to look like a business rather than a text file.
- Trades and contractors quoting jobs where materials are bought up front, the scope moves, and the paperwork has to survive an argument six weeks later.
- Small studios and agencies who need documents that match each other and terms that match the contract.
- Anyone who has been paid late, which is most people who invoice, and needs to work out a fee and write the letter that goes with it.

Accounts, and why they are optional
Everything above works with no account at all. An account exists for one reason: so your business details, clients, quotes and invoices are still there tomorrow, and so a quote can turn into an invoice without retyping it.
If you make one, the dashboard follows a job from quote to payment: send it by email or WhatsApp, the client accepts it from a link with no account of their own, you log the work as it happens, and the invoice is built from what was quoted plus what was actually done. What is owed, what is overdue and what has been collected are worked out from your own rows rather than typed in twice.
What is stored, where it sits and how to delete it is set out on the privacy page, in plain language.
How the tools are kept honest
- Checked against real figures. Tax and payroll calculations are verified against published rates rather than assumed, and the working is shown so you can check it yourself.
- Stated limits. Where a rule varies by state, country or circumstance, the tool says so instead of pretending to one answer.
- Not advice. These are calculators and document builders. Tax, legal and payroll rules change and differ by place, so for anything consequential, confirm with an accountant or an attorney.
Something wrong, or missing?
If a number looks off, a rate is out of date, or there is a tool you keep wishing existed, email contact@invoicetools.com. Corrections get priority over features, because a calculator that is quietly wrong is worse than one that does not exist.
Nothing you type leaves your browser explains how the tools are built so that holds, and how to confirm it in the network tab.
Common questions
Is InvoiceTools really free?
Yes. Every calculator, generator and template is free with no signup, no watermark and no limit on how many documents you create. An account is optional and also free while in beta. The pricing page lists every allowance.
Do I need to create an account to make an invoice?
No. The invoice generator, quote generator, receipt maker and all 200 templates work with no account. An account only exists so your details and documents are saved for next time.
Is my invoice data stored anywhere?
Not by the tools. They run in your browser, so what you type is never sent to a server. If you create an account, what you choose to save is stored and can be exported or deleted at any time.
Can I use these invoices and quotes commercially?
Yes. Documents you create are yours to send to clients and keep for your records. There is no watermark and no attribution requirement.
What countries do the tools work for?
The document tools work anywhere and support multiple currencies. Tax tools are country-specific: sales tax covers US states, VAT covers 40 countries, and each says which rules it uses.
Who is behind InvoiceTools?
One tradesperson in Houston, Texas, trading as Invoice Tools Inc., who invoices his own jobs with these tools. There is no venture funding behind it and no plan to sell your data, which is why the tools store nothing unless you sign in and save.
How do I report an error in a calculator?
Email contact@invoicetools.com with the figures you used and what you expected. Corrections are treated as more urgent than new features.
Do you offer an API or integrations?
Not yet. The tools are deliberately self-contained. If there is an integration you would actually use, it is worth telling us about.
