Can I emit legal Mexican electronic invoices (CFDIs) with this tool?

Yes! Use the `create_invoice` tool. You just need to provide the client's RFC, the SAT usage code (e.g., G03), and the item details. Konfío will automatically stamp (timbrar) the XML document with the SAT network to make it fully legally binding in Mexico.

How do I check when my next loan payment is due?

First use `list_loans` to find your active loan ID, then use `get_payment_schedule` with that ID to view all upcoming installments, breaking down principal, interest, and IVA taxes for each payment.

Can I pay suppliers via SPEI using my Konfío balance?

Yes, use the `create_transfer` tool with the supplier's 18-digit CLABE number and the transfer amount. Konfío processes these as standard domestic SPEI wires.
