Legal compliance is also assured! Evolved business document management 【paperlogic】

Paperlogic is an electronic contract service fully supervised by certified public accountants. It is one of the few services that allows for the differentiation between "party-type signatures," which use the electronic certificates of the contracting parties as a form of a seal, and "witness-type signatures," which use email addresses as a form of acknowledgment. In addition to the execution of contracts, it also offers the functionality to send documents such as estimates and invoices with signature information and timestamps, as well as the digitization of board meeting minutes. We provide an electronic archive as a storage function. **Features** - Ability to differentiate between party-type signatures and witness-type signatures - Standard timestamp functionality - Compliance with the Electronic Books Preservation Act (acquisition of JIIMA certification for electronic transactions and scanner storage) - Supports the digitization of various documents, not just contracts, including estimates, orders, order confirmations, invoices, and receipts. *For more details, please download the materials or feel free to contact us.*
