Digital deliveries

Understanding different types of digital deliveries: regular mail, ERDS and QERDS.

Go paperless! Deliver contracts digitally and legally.

Digital contracts contain information intended exclusively for the eyes of the addressee. So the content of an e-mail or attachment must not be accessible to people with false intent, given that even minor alterations can have major consequences.

Digitalize and secure your communications with ERDS and QERDS

We know it can be a bit overwhelming if it's first time you're hearing about ERDS and QERDS.
We have a very clear overview of everything you need to know to decide on the type of registered delivery - ERDS or QERDS - you need.


The biggest difference between regular email and secure email is the eIDAS legal framework.

Indeed, sending a 'regular' email has no legal value, since neither the sender nor the recipient can know whether the attachment has been manipulated by a third party in transit. In theory, an invoice sent by e-mail can simply be refused by the recipient.

EIDAS ensures that you can create an ERDS or QERDS article to give legal weight to your digital data transfer.

Compared to document sealing?

Basically an electronic seal is a certificate that is linked to a company instead of a person.
In Belgium, the qualified electronic seal gets the equivalent legal effect of a handwritten signature of the natural person who represents the legal person that created the seal. This means that, apart from the authentication and integrity of the seal (see eIDAS) also non-repudiation is ensured.
