In all government offices, many letter types are used for office communication. For this purpose, the "Secretariat Instruction, 2014" mentions several letter templates. However, government offices use a variety of customized templates in addition to the letter templates stated in the Secretariat Instruction to improve the efficiency of their service delivery. We will further simplify the service delivery process if the templates can be created by each office and used per their requirements. The ability to integrate with other systems will be provided by this template builder.
