For tradespeople and sole proprietors
Less admin work – more work on site
BauWalker takes over the part of the office for which a small business usually has no dedicated specialist: offers, contracts, invoices, letters and German documents.

Contracts and invoices
Invoices and contracts — in one place
Verträge
- Deadlines and duties
- Payment terms
- Contract risks
- Grounds for a Nachtrag
- Obligations of the client (Auftraggeber) and the contractor (Auftragnehmer)
Invoices and payments
- Payment plan (Zahlungsplan) and interim invoices (Abschlagsrechnungen)

Questions in your native language
You don't have to translate German bureaucracy first
Ask your question in Russian, Polish, Turkish, Ukrainian or German. BauWalker looks for the answer in German documents and sources and explains the result in your language — German technical terms stay where they matter for the work.
A typical day as a master craftsman
Before and after BauWalker
Without BauWalker
- In the morning, a letter in German — you only half understand it.
- At midday on site, a question about extra work: "Is this still in the contract or already a Nachtrag (change order)?"
- In the evening, searching for the right passage in the PDF and the correspondence.
- At night, the invoice and the letter to the client — with a fresh mind there's no time left for them.
With BauWalker
- The letter is explained in your language, and the draft reply in German is ready.
- Answer on extra work with a reference to the contract clause — straight from the construction site.
- You find the right passage and the document with a single question.
- The Abschlagsrechnung (interim invoice) and the letter are prepared; you only review and send.
