The problem

What it solves

Renovation companies usually put every quote together by hand after a site visit: measure, look up tile and adhesive prices, add labour, add VAT. It is easy to end up a box short or with last year’s rate.

The tricky part

What had to be right

Openings and rounding. Wall area must exclude doors and windows, and materials are sold by the box, not by the m². The sheet keeps exact areas for labour and rounded quantities for materials, so neither half of the quote is off.

Inside

What it does

  • Calculator tab: room length, width, tiled height and openings in, floor and wall areas out
  • Drop-downs for tile lines, adhesive, grout and waterproofing, rounded up to full boxes and bags
  • Waste allowance by tile size: 10% standard, 12% large format
  • Labour per m² for removal, waterproofing, floor and wall tiling, plus fixed jobs
  • Price list tab with a “last updated” date for every price; VAT and quote validity in Settings
  • Quote tab that saves a numbered PDF with the logo to Google Drive

What the owner gets

One file, prices changed in one place, and quotes that look the same every time.
