About PRAXAO

Practical tools for real work

PRAXAO is a collection of free online tools for the tasks that come back every week: writing an invoice or a quote, checking VAT, setting a price, a margin or an hourly rate, and estimating construction quantities.

BUILNORA — by PRAXAO — gathers the tools dedicated to construction: concrete, blocks and bricks, rebar, screed, paint and tiles, with realistic waste margins.

Our principles

• Free and without an account: every tool works immediately, as often as you need.
• Exact: amounts are computed with decimal arithmetic and rounded correctly for each currency.
• Private: your figures stay in your browser; a document is sent to our server only to build the PDF you request, and is not kept.
• Multilingual: English, French, Spanish, German and Arabic, with localized numbers, currencies and documents.
• Honest: advertising, when present, is always labelled and separated from the tools.
