[10/15 Yokohama] Lecture Announcement | Serious DX and AI Grand Strategy 2025

Leave the digitization of various statutory documents such as contracts and invoices to us.

The "paperlogic electronic contract" is an electronic contract service that allows for the differentiation between party-type signatures, which use the electronic certificate of the contracting parties as a form of a seal, and witness-type signatures, which use email addresses as a form of a recognition seal. In addition to concluding contracts, it also offers the functionality to send documents such as estimates and invoices with signature information and timestamps, as well as the ability to digitize board meeting minutes. We provide an electronic archive as a storage function. The electronic archive not only stores contracts concluded using the electronic contract function but also allows for the import of PDFs, supporting electronic transactions and scanner storage in accordance with the revised Electronic Bookkeeping Act. PDFs registered are read using AIOCR, minimizing the effort required for data entry. 【Features】 ■ Ability to differentiate between party-type signatures and witness-type signatures ■ Standard timestamp functionality ■ Compliance with the Electronic Bookkeeping Act (acquisition of JIIMA certification for electronic transactions and scanner storage) ■ Support for digitizing various documents, including contracts, estimates, purchase orders, order confirmations, invoices, and receipts *For more details, please download the materials or feel free to contact us.

In line with the revised Construction Industry Law of 2025, "paperlogic Electronic Contract" has been enhanced with the "paperlogic Construction Document DX Pocket." With paperlogic's strength in "visual operation," users can simply upload documents along the screen to facilitate electronic contracts and internal signatures. Additionally, features have been added for automatic linking between general contractors and subcontractors, as well as the ability to send documents with automatically applied signatures and timestamps via email. The digitization of contract operations in the construction industry not only significantly reduces mailing costs, labor costs, and stamp duties but also contributes to stabilizing contracts between general contractors and subcontractors. ■ Four Features of "paperlogic Construction Document DX Pocket" - A package price that is significantly more economical than the usual price, covering both general contractors and subcontractors. - Provision of user guides and legal guides tailored for the construction industry. - A comprehensive product that includes electronic tools for the construction industry without the need to contract various services. - Automatic storage of documents exchanged between general contractors and subcontractors, ensuring zero loss. ■ Benefits of Digitizing Contract Operations... - Significant reduction in stamp duties! - Significant reduction in mailing costs and labor costs! - Up to 60% reduction in time spent on document creation and management (compared to our company). → This also leads to improved operational efficiency.
