/ what it does

How does the AI help?

Számlázz.hu is one of Hungary's leading invoicing platforms. The connector authenticates with a static Számla Agent key generated in your web account — a non-expiring token, no "kicked out every few days" OAuth instability. The connector supports the full invoice and receipt lifecycle: issuance, storno, query, payment registration, and proforma flow. Financial safety: the connector dedup-prechecks every invoice creation, so retries do not produce duplicate documents.

/ use cases

What can you do with it?

No coding, no API docs. Just plain English.

🧾

Invoice creation in plain language

"Issue an invoice to Kovacs Kft. for 150,000 HUF with 27% VAT, due tomorrow" — the connector builds the XML, validates line totals, and returns the issued invoice number.

📰

Proforma to final invoice

"Create a proforma for 300,000 HUF for Example Ltd." — proforma issuance, and one call later it can be deleted when the final invoice is in place.

🔁

Storno in a single command

"Cancel invoice 2026/SZ-0042" — the connector creates the storno counterpart and returns the new storno invoice number.

💵

Cash/card receipt issuance

"Issue a 9,990 HUF cash receipt" — produces the receipt instantly with the pre-registered prefix.

/ tools
