Fully Managed NAV Compliance, No Portal Needed
Purpose-built for Hungary’s NAV Online Számla requirements, this solution removes the need for manual portal navigation or external compliance agents. Your only job is handing over your invoice data.
Rather than logging into NAV or managing real-time invoice reporting internally, you simply pass your invoice information to Advintek. Our proprietary Invoice Factory platform takes over completely — handling everything from field validation and data mapping through to submission, cancellation management, and long-term secure archiving.
What is E-Invoice as a Service for Hungary?
Advintek’s E-Invoice as a Service is a completely handled solution built to keep businesses on the right side of Hungary’s real-time invoice reporting obligations under NAV — without requiring dedicated compliance staff or complicated portal access.
This service works especially well for SMEs, legal practices, retail businesses, and enterprises active in Hungary that want full compliance without developing internal systems or working through NAV’s regulatory framework independently. Passing the complete e-invoicing process to Advintek means your business gains time, cuts out errors, and always holds audit-ready records — without your team ever needing to open the NAV Online Számla portal.
No portals. No manual entry. No risk of non-compliance. Just seamless automation — powered by Advintek.
How It Works – Simple 3-Step Process
Advintek’s E-Invoice as a Service for Hungary is designed to be as friction-free as possible. No portal credentials. No outside agents. Here is exactly how the process runs:
Hand Over Your Invoice Data
Share your invoice details with Advintek through whichever channel works for you — email, secure file upload, or a direct system connection. No specific formatting, manual preparation, or technical work is needed from your side at any point.
We Check, Format and File With NAV
Our proprietary Invoice Factory system runs automated checks across your data, maps every invoice field to the structure NAV's Online Számla system requires, and files it securely in real time — capturing all required tax fields and submission metadata automatically.
Confirmation Arrives, and Your Archive is Ready
Once NAV processes your invoice successfully, you get an immediate status update confirming the outcome. Every record is then held in fully secured storage for the complete retention period required under Hungarian tax legislation.
