Sign your invoices !!

According to Law 59/2003 on electronic signatures in Spain, an electronic signature is a set of data in electronic form, recorded alongside other data or associated with it, which can be used as a means of identifying the signer.
The electronic signature allows the signatory to be identified unequivocally and ensures the integrity of the signed document, i.e., that the signed document is exactly the same as the original and has not been altered or tampered with. This allows the necessary trust to be established for the exchange of messages between the sender and the recipient.
The electronic signature shall have the same value with respect to data recorded electronically as a handwritten signature has with respect to data recorded on paper.
This signature must be made with a Digital Certificate issued by a Certification Authority, which certifies the ownership of the same. The operation of the electronic signature is based on a public key and a private key. Each party has a pair of keys, one used for encryption and the other for decryption. Each party keeps one of the keys secret (private key) and makes the other one available to the public (public key).
The public key is the part that “travels” in electronic transactions and allows the identity of a citizen to be authenticated. The private key is only in the possession of the signer and is used to perform the signing process .

With the latest version of Fact-line, you can now sign invoices generated in PDF format with a digital certificate. Both from the manual editing of an invoice and from the automatic invoicing that generates all invoices in PDF format, signs them, and sends them by email to customers who have been configured to receive them. An option has also been added to sign any PDF selected by the customer.
