Electronic Signature Document Signing
The module enables signing documents with a qualified electronic signature (QES/UQES) directly within the on-premise version of Bitrix24. Cloud versions of the platform are not supported. Signed files are generated with a visual stamp in PDF format and retain full legal validity under Federal Law No. 63-FZ 'On Electronic Signatures'.

Built-in Digital Signature for BUS
The module enables signing PDF documents with a built-in electronic signature (QES/EQES) directly on the website. Documents signed with QES or EQES have legal force equivalent to a handwritten signature in accordance with Federal Law No. 63-FZ "On Electronic Signatures." A visual signature stamp is automatically embedded in the signed file.
