Kavento - Free business calculators and invoices, no account needed

by•
A free invoice generator and seven business calculators that run entirely in your browser. Fill in an invoice, pick one of five templates, download a print-ready PDF. No sign-up, no watermark, and nothing you type is ever uploaded. Every calculator prints its formula and a worked example, so you can check the answer instead of trusting it. Plus invoice guides for 12 trades: photographers, contractors, caterers, movers, electricians and more.

Hi Product Hunt 👋 I kept needing a quick invoice and a margin calculation, and kept landing on tools that wanted an email address first, or that watermarked the PDF unless I upgraded. So I built the version I wanted: no account, no watermark, no upsell. The part I'm most pleased with is invisible. The invoice preview you see and the PDF you download are literally the same file - generated once in your browser with pdf-lib and shown back to you - so the preview can never drift from what you actually send. Most builders draw an HTML preview and generate the PDF separately. There's no backend at all, which makes the privacy claim boring rather than impressive: your invoice data has nowhere to go. The site does load analytics and the privacy page says so, but nothing you type into an invoice or a calculator ever leaves the page. Open the network tab and check. The part that took longest wasn't the generator. It was writing invoice guides for 12 specific trades - the licence line a photographer needs, the retainage a contractor holds back, the purchase order that decides whether a consultant gets paid this month. I'd genuinely like to know which calculator is missing. Tell me what you needed and couldn't find.
