How it works

One kitchen. Six steps. Every number carried through.

Measurements feed the calculators, quantities feed the budget, deliveries show what is ready, and finished work moves the progress bar. You enter a number once and MILBET keeps it in sync.

  1. Measure

    Add the room as a zone. Enter length, width and height, then the doors and windows. MILBET subtracts the openings and works out every area you will need.

    Zone · Kitchen5.00 × 4.00 × 2.60 m
    Floor area20.00 m²
    Perimeter18.00 m
    Walls, gross46.80 m²
    Openings (2 windows, 1 door)− 6.80 m²
    Walls, net40.00 m²

  2. Plan

    Pick works from ready templates or write your own. Each one gets dates, a zone, a checklist and a status, so the whole job is visible in one list.

    Work plan3 of 5 done
    • Remove old tiles and cabinets
    • Patch and plaster walls
    • Prime walls
    • Paint walls, 2 coats
    • Lay floor tiles

  3. Calculate

    Open a calculator from the zone and the area is already filled in. You see the formula, the waste percentage and exactly where the result was rounded up.

    Paint · walls8.8 L
    40.00 m² × 2 coats ÷ 10 m²/L × 1.10 = 8.80 L
    Tile · floor15 boxes
    20.00 m² × 1.10 = 22.00 m² ÷ 1.5 = 14.67 → 15 ↑

  4. Buy

    Every result becomes a material you can price and track from Needed to Delivered. Partial deliveries are counted, and each work shows whether its materials are ready.

    Wall paint, matt whiteDelivered8.8 L · €96.80
    Porcelain floor tile 60×60Partially delivered9 of 15 boxes · €435.00
    Tile adhesive C2TENeeded5 bags · price not set

  5. Budget

    Planned and actual costs for materials, labour and extras add up on their own. You always know what is left, and an overrun shows up the moment it happens.

  6. Report

    Export a clean PDF or CSV of the project, the materials, the budget or the work plan. Send it to a client, a supplier or your crew through the iOS share sheet.
