Hungary
Custom ERP and billing, AI agents, web applications and SaaS for pharma and financial services businesses in Budapest. Built by Flip Retail in Jaipur, India, and delivered remotely, with working software every two weeks.
01 — Local economy
A pharmaceutical tradition more than a century old continues at Gedeon Richter, Egis and Sanofi's Chinoin plant, and OTP Bank and the oil group MOL run their Central European businesses from Budapest. Morgan Stanley, BlackRock and other multinationals operate large finance and IT service centres here, distribution centres line the M0 ring road, and tourism and conferences support a big hospitality sector.

03 — Compliance
What an ERP, billing system or AI agent has to respect here.
| Indirect tax | VAT (ÁFA), standard rate 27%Standard rate 27%, the highest in the EU, with reduced rates of 18% and 5%; returns are monthly, quarterly or annual. The tax authority NAV pre-fills draft VAT returns (eÁFA) from invoice and cash-register data. |
|---|---|
| E-invoicing | Mandatory · NAV Online Számla (real-time invoice reporting, RTIR)Data from virtually all invoices issued by Hungarian VAT taxpayers (B2B, B2C and to foreign customers) must be reported to NAV in real time via the Online Számla system, but the invoice itself may still be paper, PDF or XML. NAV has published a ViDA-aligned concept for mandatory structured e-invoicing, which was not yet law at last check. |
| Data protection | GDPR plus Act CXII of 2011 on Informational Self-Determination and Freedom of Information (Infotv.)GDPR applies directly, supplemented by Act CXII of 2011 on Informational Self-Determination and Freedom of Information (Infotv.) and supervised by the NAIH; B2B buyers expect an Art. 28 data processing agreement, a sub-processor list and, in practice, EU/EEA hosting or SCC-covered transfers. |
| AI rules | The EU AI Act applies directly: prohibited AI practices have been banned since 2 Feb 2025, general-purpose AI model rules apply since 2 Aug 2025 and transparency duties (e.g. chatbot disclosure, AI-content labelling) since 2 Aug 2026, while the Digital Omnibus on AI (in force 27 Jul 2026) moved stand-alone high-risk (Annex III) obligations to 2 Dec 2027 and product-embedded high-risk (Annex I) obligations to 2 Aug 2028; Hungary has designated its national AI Act authorities. |
| Systems we migrate from or connect to | Számlázz.hu, Billingo, Kulcs-Soft, Novitax, RLB-60, SAP Business OneMasters, ledgers, stock and open balances move across and are reconciled before cutover. |
| Payment rails for web apps and SaaS | SimplePay, Barion, Stripe, Instant transfers (AFR), SEPA (for EUR transfers) |
| Also worth knowing | Invoicing software must transmit XML invoice data to NAV automatically at issue, and retail sales go through online cash registers connected to NAV. Automated submission requires the taxpayer to set up a technical user in the Online Számla system. |

Yes. Invoicing is built for Hungary's VAT (standard rate 27%).

You choose: your own cloud account in a region that suits you, or your own servers. Access inside the system is role-based, and during development we work on test or masked data wherever possible. GDPR applies directly, supplemented by Act CXII of 2011 on Informational Self-Determination and Freedom of Information (Infotv.) and supervised by the NAIH; B2B buyers expect an Art. 28 data processing agreement, a sub-processor list and, in practice, EU/EEA hosting or SCC-covered transfers.
Yes. Masters, ledgers, stock and opening balances move across and are reconciled with your accountant before cutover, ideally at a year-end or quarter-end.
Yes. Current language models handle Hungarian and English well, including mixed-language messages. We still test an agent in each language your customers use before it goes live, and route anything it is unsure about to your team.
Usually one module that fixes the most expensive problem first. For pharma & life sciences that is often batch & expiry control and formula and recipe management. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
