What is a delegated signature?

A delegated signature is a type of digital signature in which a third party is authorised to digitally sign for the original signatory.

Docuten offers clients the possibility of authorising the platform to digitally sign invoices. The invoice is signed by a certificate issued by the “Certification Authority” to Docuten.

This type of signature is fully legal. Article 5.3 of Royal Decree 1496/2003 of November 28 indicates the possibility of outsourcing invoice issuance to a third party.

Allowing Docuten to sign your electronic invoices means you don’t need an electronic certificate in the name of the company. It is a fully valid and secure option for your company, and you avoid the expense of purchasing an electronic certificate. It also saves a lot of time since the signature is done automatically at the time of sending without needing any further action. What’s more, the use of a delegated signature is compatible with any browser (Chrome, Firefox, Edge, Safari, etc.). In contrast, signing with your own certificate can only be done via Explorer.

To use it, check “Yes” in the Delegated signature option under “Preferences” > “Invoice format”. The invoice will be signed automatically without needing to take any further action.

All of the solutions offered by Docuten comply with the eIDAS Regulation, along with other international regulations on digital signature. Feel free to contact us if you have further questions.
