ProfiSuite Intelligence · an in-house AI assistant
Your digital foreman who thinks ahead.
Other AI tools know nothing about your business. ProfiSuite Intelligence already. The self-built analysis looks at revenue, outstanding receivables, capacity utilisation and quote conversion rate, and tells you every morning what you need to look at today. Like a site foreman who knows the place, except he works around the clock.
- Daily briefing at the push of a button What's urgent today — in one sentence, every morning.
- Forecasts instead of gut feeling Revenue forecast, expected closings and liquidity for the next 8 weeks.
- Warns before things go wrong Overdue invoices, bottlenecks and sick-leave rate in view early on.
Basic
Live key figures, business health score, liquidity and capacity utilisation, always included in ProfiSuite Handwerk.
Pro PRO
The personal AI business assistant: daily briefing, projections, forecasts, cross-tool context.
🔒 GDPR-compliant and transparent: you decide for yourself whether you use Pro. What is processed is clearly disclosed in the consent.
ENTERPRISE After 1 year, ProfiSuite Handwerk Intelligence Pro
Request process optimization
One year of data, then we optimize your entire business.
If ProfiSuite Intelligence Pro once it has run in your business for a year, there is something no other tool has: real history data from your business. That is exactly what the data-driven process optimisation on — a complete review that only in combination with ProfiSuite Intelligence Pro is possible (Enterprise package).
Your own numbers are used to show concretely where your business can save money and time, for example:
Buying materials at the right time
When to order which material cheaply and in time, based on your actual consumption and price trends.
Staff and deployment planning
Spot utilisation, peaks and idle time — deploy teams where they bring in the most revenue.
Offer & pricing strategy
Which jobs really pay off, what quote rate you're running, and where margin slips away.
Liquidity & seasonality
Plan ahead for seasonal patterns, incoming payments and bottlenecks, instead of just reacting.
...and everything else that can be analysed from your ProfiSuite data, tailored individually to your business.
AvailableOnly in the Enterprise package, in combination with ProfiSuite Intelligence Pro

REQUIRED IS COMING Already built in today
E-invoicing 2028? You're already ready.
Receive domestic businesses must be able to process e-invoices since 1 January 2025 — including small traders. For the Exhibition transition periods and exemptions apply: for prior-year turnover above €800,000, the general transition period ends in 2026; at €800,000 or less, it ends at the end of 2027. Small business owners are exempt from the invoice issuing obligation. Where the obligation applies, a simple PDF afterwards does not count as an e‑invoice.
ProfiSuite Handwerk can do both today, so you won't have to change anything in 2028:
- Reception & shipping, digital — ZUGFeRD and XRechnung (standard EN 16931), exactly the formats the tax office requires.
- From quote to e-invoice — one click, done and structured, no standalone solution, no second program.
- Archived in original format — changes logged; can form part of a GoBD-compliant process. Incoming e-invoices are automatically filed in the correct folder.
In short: receiving and sending are technically ready — regardless of when the obligation applies in your case. Status: March 2026. General information, not tax advice; your tax advisor will clarify the details.
GDPR · legal certainty · data protection
Your data belongs to you.
Data protection is not an afterthought stuck on here. It is built into the architecture. Briefly and honestly, here is what that means in practice:
Servers in Germany
Hosted at Hetzner in Nuremberg/Falkenstein. No transfer to third countries. A data processing agreement is in place.
Field-level encryption
Salary and IBAN are encrypted with AES-GCM. The key is unlocked per role via PIN (PBKDF2). The apprentice cannot see salaries.
No trackers
No advertising, tracking or analytics services. All fonts and libraries are embedded locally, with no third-party requests.
Audit log with hash chain
Every change timestamped and attributed to its author. Tampering with the chain is detected, documented in a traceable way: timestamp, author, hash chain.
GoBD & 10 years
Tamper-proof document storage, 10-year retention for invoices and e-invoices in their original format (XML).
Versioned consent
GDPR consent with digital signature, privacy policy in the app, anonymisation for analytics, withdrawal possible at any time.
2-factor & roles
TOTP 2FA for sensitive roles (managing director/accounting), device binding, brute-force lockout, session timeout, granular permissions.
Data subject rights
Access, rectification, erasure, data portability (JSON export) — can be done directly from the app.
You will find more details in the Privacy policy and under Hosting & security. The full record of processing activities (Art. 30 GDPR) is ready for every business.

Frequently asked questions
What you want to know.
Do I need internet for ProfiSuite Handwerk to work?
No. ProfiSuite Handwerk keeps your data on the Device and keeps working offline too — in a dead zone on the construction site, in the cellar, in the car. As soon as the connection is back, it automatically syncs everything with the server, without losing anything.
Does ProfiSuite Handwerk run on iPhone and Android?
Yes. ProfiSuite Handwerk runs on iOS and Android and in the browser on the office computer. The journeyman clocks in on mobile, you make quotes on a tablet, and in the office you work on a large screen. On a phone, it can be added to the home screen like a real app.
Is my data GDPR-compliant and secure?
Yes. The data sits on a German server (Hetzner, Nuremberg/Falkenstein). There are no external trackers or advertising services, and all fonts and libraries are embedded locally.
