Digital signature

Sell&Sign is a SaaS solution allowing to implement digital signature on all types of documents.

Nowadays, the handwritten signature is slow and unreliable, to the point that it creates a certain administrative phobia in more and more French companies! Practices such as e-mail agreement, contract scanning, copy-paste of signatures previously drawn on PC are developing, to save time, but present lots of risks. In a 100% digital economy, and because we are at the dawn of a generalization of digital transactions, digital signature is increasingly relevant.
