Practical tools, open workings
The toolkit covers concrete, masonry, boards, paint, flooring, roofing, labour, pricing, equipment and cash flow. Each tool shows the formula, an example, assumptions and common mistakes. Values are editable planning scenarios, not industry benchmarks or supplier quotes.
Regional context without hidden assumptions
Region selection chooses language, currency formatting and initial units. It never converts currencies or certifies a local tax rate. Tax and cost inputs must come from your own project records. European English uses Ireland and EUR as its starting context; it does not represent a single rulebook for Europe.
Corrections and ownership
Numbriv maintains the software and educational content. Automated tests check selected formulas, conversions and interface flows; they do not constitute professional certification. Send a correction with the page address, non-confidential example inputs and the reason you believe the result should differ.
