How Vinkius protects your data

Can I set different limits for each virtual assistant on my team?

Absolutely. You have full control in our command center. You can create an AI agent that only "reads" data so the support team can answer questions, and another superpowered agent that can "edit" and "create" information exclusively for your operations team. Each AI gets exactly the level of access you allow.

What happens if the underlying API rate limits my agent?

Our edge infrastructure automatically handles backoffs, queueing, and throttling. If an AI agent sends too many erratic requests, Vinkius manages the rate limits gracefully, ensuring your backend doesn't crash.

How does the AI access my passwords and credentials?

It simply doesn't. On Vinkius, your passwords, API keys, and login details are kept in a secure vault. The AI (like ChatGPT or Claude) merely "asks" Vinkius to perform the task. Vinkius opens the door, does the work, and hands the result back to the AI. Your credentials are never seen, read, or learned by the artificial intelligence.

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

Absolutely. Use the list_posting_categories tool 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.

What can AI Agents do with Lexware Office (Accounting & Invoicing)?

The Lexware Office (Accounting & Invoicing) integration provides structured, LLM-friendly schemas for reliable tool execution within your agentic workflows.

The Future of bookkeeping

The Lexware Office (Accounting & Invoicing) toolkit provides AI native integration for bookkeeping. It structures data so Claude Code can accurately process finance accounting requirements.

Connecting invoicing with Cursor

Use Lexware Office (Accounting & Invoicing) to interface with invoicing via natural language. The toolkit provides Cursor with LLM-friendly schemas for finance accounting tasks.
