List the last 5 invoices from InvoiceXpress

I've retrieved the latest 5 invoices. Highlights include FT 2026/1 (€1,200), FT 2026/2 (€450), and FT 2026/3 (€2,100). All documents are in the 'Finalized' state. Would you like the PDF link for any of these?

I've found client 'TechPorto' (ID: 12345). Their fiscal ID is 500123456 and they are located in Porto. They have 3 active estimates pending approval. Would you like to see their contact history?

What are the active VAT rates in my account?

I've identified 3 active VAT rates: 23% (Normal rate, ID: 1), 13% (Intermediate rate, ID: 2), and 6% (Reduced rate, ID: 3). There are also 2 exemption codes configured for international services. I can provide the IDs for your item mappings.

Yes. Use the `get_invoice` tool with a specific Invoice ID. Your agent will return all document details along with a permalink to the signed PDF, allowing you to view or share the official fiscal document instantly.
