Standard software for your SHK (Sanitär, Heizung, Klima — plumbing, heating, AC) business — bought, not rented
Maintenance in a spreadsheet, Datanorm only as a paid extra, the emergency job written on a slip of paper in the van? krafteq Handwerk is standard software for plumbing, heating and air conditioning — from the enquiry through quote, job and time tracking to the e-invoice and the export to your tax advisor. Bought once instead of rented monthly, in a dedicated installation for your business. Based in Leverkusen, for SHK businesses across the Rhineland and all of Germany. We are currently rolling krafteq Handwerk out with the first businesses: you test it free of charge, receive an individual offer afterwards, and we set up your business together with you.
GAEB tender import and Datanorm are built in — not sold as a paid extra.
Target audienceDoes this sound familiar?
krafteq Handwerk is built for SHK businesses with 5 to 50 employees — owners and master tradespeople who carry out plumbing installation, heating engineering and air conditioning work. These are the situations we encounter most often:
Maintenance running in a spreadsheet
You have 80, 200 or 400 maintenance contracts for heating systems, heat pumps and air-conditioning units — but the reminders, appointments and service reports all live in a growing spreadsheet. Miss a service and you have an unhappy customer, sometimes a liability claim.
Datanorm charged as an extra in the subscription
Your wholesaler delivers product and price data in Datanorm format. With the subscription providers that interface is often a paid extra module. In krafteq Handwerk it is built in — together with catalogue and supplier prices for your costing.
GAEB tenders are tedious manual work
Architects and main contractors send GAEB files for heating and plumbing lots. You transfer the line items manually into your quoting tool. Hours are lost, typos creep in. GAEB import belongs in every serious SHK software.
Emergency jobs end up on scraps of paper
Boiler failure, burst pipe, no hot water — emergency calls come in evenings and at weekends. Raise the job, record the call-out and the hours, book materials: from a smartphone, without double-keying everything on Monday.
Heating subsidy documentation creates mountains of paperwork
Subsidies for heat pumps and boiler replacements require clean documentation: appliance type, installation, commissioning, efficiency. We structure your jobs so that your customers can file their applications easily — we do not advise on subsidy applications, but we make the data readily available.
Your subscription software cannot be changed
TAIFUN is deeply specialised for the SHK trade and is purchased — no public list prices; according to the vendor the price depends on workstations and modules (as of Aug 2026). ToolTime, plancraft and HERO run as one system for all customers at once — customer-specific changes are typically more limited in standardised multi-tenant operation, and the exact scope differs from vendor to vendor. And where the price hangs on seats, the monthly bill grows with it: plancraft bills each further office and mobile seat separately, HERO each further app licence, ToolTime tiers by team size (TEAM up to 5, MAX up to 10 employees) — as of Aug 2026.
FeaturesWhat krafteq Handwerk covers for SHK businesses
A job runs all the way through: enquiry, quote, costing, scheduling, site documentation, time tracking, e-invoice, accounting export. The installation arrives with the terms, units and templates of the SHK trade — not as an empty system.
Job management with materials, hours and call-out
Create SHK jobs, track status, schedule engineers. Per job: line items with pipes, fittings and radiators, hours per engineer, activity types for travel and work. Linked to the customer record, photos and the site diary.
Recurring maintenance
Plan maintenance for heating systems, heat pumps, air-conditioning and ventilation as a series — with separate work sections per appointment. Whatever is recorded on site is handled through questionnaires; you define the fields.
Maintenance contract software for plumbing and heating businessesGAEB import and export
Import GAEB files from architects and main contractors — GAEB 90 (D81/D83/D84/D86), GAEB 2000 and GAEB DA XML. Line items, quantities and descriptions land in the quote; the export (X84/X86) goes back validated.
Datanorm from your wholesalers
Read and write product and price data from your plumbing wholesaler via Datanorm. Catalogue categories with the units of the trade, supplier conditions, costing with a real surcharge structure per cost type.
Calculation software for plumbing and heating businessesPlant data on the job
Manufacturer, type, serial number, commissioning date and the history of previous visits sit with the customer and on the job — recorded through questionnaires, findable again at the next service. On the next visit the engineer has the data on their smartphone.
Site view for engineers
The interface is a web application and runs in the browser on smartphone and tablet. The site sees a lean day view: job, site measurements, hours, receipts — no prices, no customer data, no settings. The cut is enforced on the server.
Photo and site documentation
Site measurements, defects, site diary and photos sit on the job instead of in five chat threads — plumbing installation, boiler fitting, AC installation. Everything stays together and can be issued as a document.
E-invoicing (XRechnung, ZUGFeRD)
Structured invoices for public-sector clients and in B2B — receiving has been mandatory since 2025, and sending becomes mandatory in stages from 2027 and 2028 under the German Wachstumschancengesetz. Plus interim, final and recurring invoices, open items, dunning and the DATEV export for your tax advisor.
ProductThis is what your SHK software looks like
Heat pump, buffer cylinder, composite pipe, maintenance contract — the terms are already in there. The screens are in German, the language of the product.
Open quotes, overdue invoices, running jobs and cash balance at a glance — the state of the business when you open the app.
The day view for office and site: today's activities and your own attendance with breaks.
Maintenance contracts sit as jobs of their own in the same list as new business — with status, contact and owner, filterable by maintenance.
The existing plant is recorded on the job: what comes out and what goes in, plus contact, billing type and job total.
Weather, crew size and incidents per working day, stored on the job — from the old boiler removed to the hydraulics piped up.
Quotes, invoices and reminders with recipient, status and amount in one list — from draft through released and paid to overdue.
Receipts and payments with posting suggestions, collected as the package for the tax adviser and exported per period.
Hours per job, booked day by day and per fitter — the basis for post-calculation and progress invoices.
Weekly planning with lanes for enquiries, jobs, teams and people: who is on which site, and when.
The trade's article master with article number, unit and supplier — the basis for calculation and quoting.

How it worksYour own SHK installation in three steps
No sales process, no open consulting invoice. You see a running system with your own data before terms are discussed.
-
Submit your enquiry
Describe your SHK business briefly in the form — size, focus (plumbing, heating, air conditioning), what is currently causing trouble. It takes five minutes. Only the industry is required, everything else is optional.
No sales call, no sales pressure, no obligation.

Your test instance
We set up your test instance — with the terms, units and templates of the SHK trade, with the wage groups and catalogue categories of your trade — and send you the access, usually within three working days. You create a real maintenance job and see whether it fits.
You judge a running system, not a plan.

Quote and start
If it fits, you receive an individual written offer: a fixed-price perpetual licence for your business, plus running your installation — with krafteq as an annual service with the first year included, or self-hosted on your own server. We set up your business together with you. Fine-tuning after go-live is included; its scope is set out in your quote.
Pay once, use indefinitely. Whatever does not fit in the first months, we fine-tune.
What you getFour building blocks — in every quote
You buy the software. You rent the operation — or run it yourself. Those are two separate things and they stay separate. The concrete terms are set out in your quote, not on this page.
Fixed-price perpetual licence — one-off
You buy a perpetual right to use the software as delivered. Paid once, no monthly licence fee, no minimum term. Billed per business, not per user and not per workstation — the seats for your engineers are therefore included.
Your own installation per business
Your own database, your own domain, your own configuration — not a shared system with other businesses. That is precisely why a change for your business is possible at all. Data export at any time.
Operation as you prefer
Run by krafteq as an annual service — the first year is included, after which security updates, backups, monitoring and support run through it. Servers in Germany, GDPR data processing agreement. Or self-hosted on your server or at your IT provider. Or entirely offline in your own network.
Fine-tuning and updates
All updates and security updates are included in the first year, as is fine-tuning after go-live within the agreed scope: whatever does not fit your SHK business in the first months, we fine-tune. After that, updates run through maintenance — and without maintenance your version simply keeps running.
Comparisonkrafteq vs. TAIFUN, plancraft, ToolTime, HERO & Co.
The established providers deliver solid software — TAIFUN in particular is deeply specialised for the SHK trade and, unlike the cloud vendors, is purchased rather than rented. The difference is not a feature list but the model behind it: how it is billed, what remains after a cancellation, and whether your business gets its own installation.

TrustWith the rigour of a German engineering partner
krafteq is a German GmbH based in Leverkusen. We have served enterprise clients in industry and manufacturing for years — and we build krafteq Handwerk to the same standards.
krafteq GmbH, Leverkusen
German company headquartered in the Rhineland. A fixed, German-speaking contact in Germany — not a call centre. Meetings on site are possible, fully remote equally so — typical travel time to SHK businesses in Cologne, Düsseldorf and Bonn is under an hour.
Security built into the process
Every change is reviewed, credentials are held in a secured vault, and every release is checked for known vulnerabilities.
Data in Germany, or in your own network
Run by krafteq on servers of European providers (Hetzner, OVHcloud or IONOS, depending on requirements) in Germany — data processing agreement (DPA) available as standard, sub-processors and safeguards documented in the DPA and the TOMs, encryption in transit (TLS 1.2+) and at rest, a dedicated database for your business. Or self-hosted, or entirely without an internet connection.
Built by Senior Engineers
Every specialist brings at least ten years of professional experience. The people building krafteq Handwerk have already delivered critical systems in enterprise environments.
“Maintenance, plant data, GAEB and Datanorm are not exotic edge cases — they are everyday SHK work, which is why they are built in rather than bought in. An SHK business cannot describe in advance what its software has to do; it notices once it works with the thing. That is why you get standard software in your own installation, bought instead of rented — and whatever does not fit in the first months, we fine-tune.”
