Számlázz.hu integration

Számlázz.hu integration: automated invoicing in your webshop

Számlázz.hu is Hungary's most widespread online invoicing service — and the most mature one for webshop automation. Once connected, a NAV-compliant invoice is generated automatically for every order: no manual retyping, no forgotten documents, no mistyped tax numbers. The customer receives the invoice by email, and you save hours every week.

Automatic invoice issuing

On payment or fulfilment, the invoice is created and delivered by itself.

NAV online reporting

The mandatory tax-authority reporting happens automatically through Számlázz.hu.

Storno and credit notes

Returns and modifications handled with correcting documents, from the shop.

Aligned with payment methods

Instant invoice for card payments, on delivery for COD — matching your process.

Why automate invoicing?

Above ten orders a day, manual invoicing eats hours weekly, and every manual step is an error opportunity: wrong tax number, missed item, forgotten storno. In the era of NAV online invoice reporting, a botched document isn't just an inconvenience — it's a penalty risk. Automated invoicing solves all of it at once: documents are always accurate and on time, and your accountant receives clean, exportable data.

How we connect Számlázz.hu

We integrate through the Számlázz.hu Agent API: invoices are configured to be issued on payment receipt or order fulfilment, with your shop's VAT rates and payment-method mapping. The e-invoice is delivered to the customer automatically, and the PDF is attached to the order in your admin. We pay special attention to the edge cases: advance payment, partial fulfilment, cash on delivery and returns — we have a proven flow for each.

Strongest together with payment gateways

Automated invoicing shows its real power combined with payment integrations: a successful SimplePay or Barion payment triggers the invoice instantly, a Stripe order from abroad produces the right currency-and-VAT document, and for COD the courier's delivery confirmation can trigger invoicing. The whole chain — payment, invoice, NAV reporting — runs without human touch, error-free.

Frequently asked questions

Do I need a paid Számlázz.hu plan?

API (Agent) usage requires an appropriate Számlázz.hu subscription — we help you pick the plan based on your invoice volume; the entry tier is usually enough.

I have several webshops — can they share one account?

Yes, Számlázz.hu handles multiple invoice blocks, so your shops' documents run in one account, still separated.

What happens on a return?

A storno or credit invoice can be initiated from your shop admin, automatically reported to the tax authority — no manual work.
