Knowledge

Create an invoice, quote and Nachtrag in your own words

Describe what you did. From that, a document in German is created, which you review before sending.

Which document do I need?

That depends on the situation: A quote states what you offer at what price. A cost estimate is a non-binding estimate. The invoice requests payment for work performed. A Nachtrag covers additional or changed services.

Invoice: progress invoice (Abschlagsrechnung) or final invoice (Schlussrechnung)
Quote or cost estimate
Nachtrag with justification
Letter to the client
Acceptance report (Abnahmeprotokoll)

Choose the document type – customer and project data are filled in

How the draft is created

You describe the task in your language, by text or voice. BauWalker asks for anything missing and prepares the document in German: recipient, subject, salutation and text.

Draft of a letter to the client: download, edit, send

Who calculates and who decides

Amounts and VAT are calculated by the platform using fixed rules, not by the language model.
You enter prices and quantities yourself – BauWalker does not suggest prices.
A document is sent by email only after your explicit confirmation.

Abschlagsrechnung: what matters under VOB/B

If the VOB/B has been agreed, interim payments (Abschlagszahlungen) are to be granted in the amount of the value of the verified services rendered in accordance with the contract; proof is provided by a verifiable statement (§ 16 Abs. 1 Nr. 1 VOB/B). The claim falls due within 21 days of receipt of the statement (§ 16 Abs. 1 Nr. 3 VOB/B). The wording of your contract is always decisive.
