Digital shadow / Brandt Heating & Plumbing GmbH, 15 employees

Brandt Heating & Plumbing GmbH, 15 employees

A family-run SHK firm busy with service, bathrooms and heat pumps, losing evenings to quotes, funding paperwork and time sheets.

How it works

  1. Check the numbers. Each step shows the hours your company spends on it per week. Click a number to change it, or set it to 0 if the step does not exist for you.
  2. Insert building blocks. Click a coloured block in a step. Below it you read in plain words what the AI would do there and what stays with your people. The shadow under the step shrinks.
  3. Read the result. The dark bar at the bottom shows the key figures; the full calculation with cost, return and a curve is below the departments.

Block colours show how you get it:

A dashed box means no building block exists yet.

Where AI helps most here

Start with what saves the most. Many blocks run on the same platform (e.g. one AI workplace for the office): you buy it once, and every further step only needs configuring.

      The company from above

      Each building is a department. Its height shows how much work happens there, each window is a recurring task, and the shadow on the ground is the manual work. Click a building to open it. Windows light up where AI helps, and the shadow gets shorter.

      Your calculation

      Example calculation for orientation. Prices, hours and savings are estimates for a fictitious company, not an offer, a promise or advice. Your real figures depend on your processes, your software and the providers you choose.

      Insert building blocks or a package to see the calculation.

      The value is working time that becomes free for other work; it is not automatically lower wages. The curve counts the freed time from the first month on. All figures are rough estimates.

      Parts list for your selection

      BlockUsed inSavesValue per yearOne-offMonthlyDataRisk of failure

      Every row shows the amount that goes into your calculation; the rows add up to the totals. Blocks on a platform (AI workplace, automation, transcription, accounting AI, ...) only cost their configuration; the platform itself appears once with its rollout and its seats or base fee (prices researched 2026). Stand-alone solutions use the middle of the catalog price band, scaled to the size of the company.

      Assumptions and sources

      Fictitious but typical firm: 1 owner-master, 1 further master/site manager, 8 journeymen, 2 apprentices, 2 office staff, 1 trainee clerk. Hours are estimates per week for the whole company, rounded, in a normal heating-season week; no hard study figures per step. Productive field work is deliberately large (about 60 percent of hours), including driving, and marked no_ai. Office and master hours reflect common complaints in the trade of 8 to 12 hours of weekly paperwork per person in management, GoBD-compliant invoicing, e-invoice receipt duty since 2025, BEG funding rules and DSGVO. Fachkräftemangel means the master often does office work in the evening, so master hours are partly overtime and not in the 40-hour week.
