FAQ
What is an e-invoice, and how is it different from a PDF?
An e-invoice is a structured XML document that follows the European standard EN 16931 and the Peppol BIS Billing 3.0 specification. Its data can be read and processed automatically by accounting software.
A standard PDF sent by email is a visual document rather than a structured e-invoice. Its data usually needs to be entered manually or extracted using additional software.
How will e-invoices be sent to customers?
E-invoices will be delivered through Peppol Access Points — service providers that securely send and receive e-invoices over the international Peppol network.
Who needs a Peppol Access Point?
VAT-registered businesses need a Peppol Access Point to send and receive domestic e-invoices covered by mandatory e-invoicing. Businesses that are not VAT registered also need one if they receive e-invoices from VAT-registered suppliers.
Does mandatory e-invoicing also apply to consumers?
No. Mandatory e-invoicing applies to transactions between businesses (B2B) and between businesses and public authorities (B2G). It does not apply to sales to consumers (B2C).
Can I use more than one Peppol Access Point?
Yes. You can use different providers for sending and receiving e-invoices. You can also send through multiple providers, but you must choose one provider for receiving.
What are the benefits of using Flowis?
Flowis lets you send, receive and manage e-invoices in one place. It converts invoices to BIS 3 format and lets you track their delivery status and history. You can also give your accountant access to the app.
For more specific needs, Flowis can connect to your accounting system and be tailored to your company’s processes.
