Trade AI.
Industrialised.
The AI reads every item in the bill, recognises the work behind it and assembles both the material and the labour share — before the first supplier has replied.
In building services the margin is decided in costing — and costing waits on supplier quotes. KraftHub reverses the order: the AI recognises the work behind every item and fills a price pool for each from your DATANORM master, the wholesale interfaces, your past projects and the labour minutes in your performance lists. Incoming supplier quotes keep adding to it. The estimator takes over a priced draft instead of an empty list.

Where the hours actually go.
Not in the arithmetic. In understanding, searching and matching — five bottlenecks and what the AI makes of each.
The planner writes freely. The estimator translates in their head.
Where catalogue text is used, matching is a lookup. Where a planner or architect wrote freely — and that is the rule — the estimator first has to recognise which service is meant. That knowledge lives in individual heads today.
The AI recognises the work behind every item — semantically, against performance lists, the article master and past items. That one recognition unlocks both the material price and the labour minutes.
The price pool fills before the first supplier replies.
Plumbing, heating, ventilation: weeks pass before the partial quotes are all in. Until then there is no number anyone can work with.
For every item the system gathers candidates from the DATANORM master, over IDS-Connect and Open Masterdata, from your past projects and from the labour minutes. The labour share is fixed the moment the item is recognised — it never comes from a supplier. So a solid price statement exists on the day the tender arrives.
The work is not the arithmetic. It is the post.
Enquiries out, second wave, third wave. Back come partial quotes as PDF, as scan, in a mail attachment — with the wrong project reference, in the wrong folder, covering a handful of items. No supplier ever prices a complete bill. Finding and filing them is the real effort.
Incoming quotes are read, matched to items and rated — scans included, wrong project references included. Where the offered make differs from the one specified, the item is put in front of a person instead of quietly accepted.
The estimator takes over a draft, not an empty bill.
The final review is a blind run through the pile today: every trade in one sitting, with no idea where the expensive uncertainties are.
The draft is priced when the estimator opens it, with the source on every item. Exceptions are sorted by value × uncertainty. They check, add the project-specific parts, set overheads, risk and profit at total level and approve.
Every costing improves the next.
Experience sits in individual heads, and every branch prices differently. None of it can be compared.
Every quote fed in, every exception resolved and every confirmed match grows the reference base. Coverage rises with each project — one pricing logic across every site.
How much can be priced without a supplier enquiry depends heavily on the trade: in ventilation the material price comes mostly from supplier quotes, while in sanitary most of it can be covered from master data and your own history. We measure that on your projects rather than promising a blanket rate.
Your article master stays the source of truth.
KraftHub replaces neither your inventory system nor your job processing. It sits on the quoting and costing process and works on the data your installers and office team already maintain.

- IDS-Connect
- Search your wholesaler's shop and pull the cart into the quote, on your own credentials.
- GAEB
- Import building-services bills of quantities from planners and main contractors, price them and return them as X84.

Operations, hosting and data protection.
German hosting, logged access, a data processing agreement as part of the contract. Two deployment models — you decide where the platform runs.
- Hosting
- Operated in German data centres by a German provider. Access is your team's alone; support access happens only on explicit approval and is logged.
- Data protection
- GDPR-compliant, aligned with IT-Grundschutz, EU AI Act taken into account. Your data stays yours: return it at any time in open formats, no lock-in clauses.
- Traceability
- Every quote is traceable: you see which inputs produced which result, and you find and correct systematic deviations yourself.
- Audit trail
- Approvals and changes stay on the record — including the history of who changed what and when.
Two deployment models.
