International invoicing system integration: compliance & real‑time billing
At Bloonde we specialise in integrating bespoke platforms with external systems to meet legal and fiscal requirements across countries.
A recent international project involved integrating the Hungarian invoicing system Számlázz, which allows real‑time invoice issuance compliant with Hungarian tax authority standards.
How the Számlázz integration works
When a sale is created, the platform prepares the structured data required for a compliant invoice. The system then calls the Számlázz API to generate the invoice in real time and email it automatically to the customer.
If the sale changes (partial or full cancellation), the platform assembles corrective / credit note data and triggers generation of adjustment documents. All invoices (originals and corrections) are stored and indexed in the backoffice, where admins can filter by date, download batches or inspect per‑sale history.

Benefits of integrating Számlázz
- Automated billing workflow – reduced manual effort and error risk.
- Real‑time issuance – customers receive documents instantly, boosting trust and service quality.
- Corrective invoice handling – precise accounting with fast credit / adjustment generation.
Overall it streamlines Hungarian operations, improves compliance posture and enhances customer experience.
