Digital Agency: "paperlogic can be used as contract documents for the national and local governments."

  • NEW
  • COMPANY

"Electronic contracts for national and local governments are also available with 'paperlogic Electronic Contracts'" In December of last year (2023), we inquired about our service 'paperlogic Electronic Contracts' regarding the 'Law and Orders Related to Regulations on New Business Activities' utilizing the Digital Agency's gray zone resolution system. As a result, we received a response from the Digital Agency stating that 'paperlogic Electronic Contracts' can be used as an electronic record in place of paper contracts for national and local government contracts. "'paperlogic' is endorsed by the Digital Agency" In this inquiry, we received confirmation that 'paperlogic Electronic Contracts' can be utilized as an electronic record in place of paper contracts for national and local government contracts. From now on, you can confidently use 'paperlogic Electronic Contracts' not only for contracts between private companies but also for all types of contracts in local government practices, including administrative contracts and discretionary contracts.
