I build free tools for small business

About

I build small web tools for small businesses — from Argentina, mostly for the US market. Kavento is the current one: a free invoice generator and a set of business calculators that run entirely in your browser. No accounts, no backend, nothing uploaded. Before that, booking software and online stores for local shops.

Kavento - Free business calculators and invoices, no account needed

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.
