Idiot Business Tools was built around a simple idea: the everyday paperwork that every small business and HR team produces — invoices, payslips, offer letters, quotations — shouldn't require expensive software, an account, or a subscription. We built a focused set of 20 business and HR document tools that run entirely in your browser, with no signup and no server ever seeing your data.
Every tool on this site follows the same design: a clear input form, a live preview that updates as you type, and a print or download option once you're happy with the result. We deliberately kept the design plain and professional, because the documents you create here — invoices, contracts, HR letters — are ones your clients, employees and vendors will actually read and act on.
Because every tool runs as client-side JavaScript, nothing you type — client names, salary figures, personal details — is ever transmitted to a server or stored anywhere outside your own device. We think that matters, especially for documents as sensitive as payslips and offer letters.
