Get to know the e-invoice
and its Access Point
The Flowis Access Point makes e-invoicing easier by taking care of everything “around” it, too.
The Peppol network
The whole system runs on the decentralized Peppol network, managed by the European Commission. It defines technical standards, security requirements and organizational rules.
Security is our top priority
Encryption
All communication is protected by end-to-end encryption (TLS/SSL), so third parties cannot read your data while it is being transmitted.
Identity verification
PKI certificates verify the identity of participants in the network, so you can be sure you are sending and receiving e-invoices with the right partner.
Audit trail
Every transaction is recorded – at any time you can trace its course and have proof of sending and delivery.
Integrity protection
Documents are protected against unauthorized changes, so the content of the invoice stays unchanged and trustworthy throughout the transfer.
Technical components of an Access Point
1. Standard format
Invoices comply with the European standard EN 16931, which ensures a uniform format across the EU. You can generate the Peppol BIS3 (XML) format automatically, right in Flowis.
2. Digital address
A unique Peppol ID generated by your Access Point serves as your address for receiving e-invoices.
3. Delivery confirmation
Message Level Status confirms that your invoice was successfully delivered to the Access Point and the Financial Administration.
4. Automatic reporting
Integration with the Financial Administration of the Slovak Republic ensures that data for VAT control is reported automatically.
5. Secure transfer
Secure encryption protects your business data.
