FAQ

Questions Lexware Office owners ask.

  • 01

    Can I create a new customer record through my agent?

    Yes. Use the create_contact capability by providing the company name, contact person, and email. Your agent will format the data according to Lexware Office standards and assign the correct role ('customer' or 'vendor') instantly.

  • 02

    How do I check the payment status of an invoice?

    The get_invoice capability retrieves the complete document structure, including the current status (e.g., 'paid', 'open', or 'overdue'). Your agent can summarize these details for you directly in the conversation.

  • 03

    Can my agent list all accounting categories available in my account?

    Absolutely. Use the list_posting_categories capability to retrieve the defined chart of accounts. This is essential for understanding how revenues and expenses are mapped to your financial reports and DATEV exports.
