@udaysingh007005, the full answer to your question depends on what you mean by “digital signature and stamp.” If you are referring to adding a graphic representation of a signature and business stamp of some kind, this can be done with custom fields of the image type. See [Use custom fields | Manager](https://www.manager.io/guides/8941) and [Add an image to a custom field | Manager](https://www.manager.io/guides/16188). If you are referring to some form of digital security authentication in the PDF file itself, you cannot add that within Manager. ---

You can automate the procedure by automatically signing all the pdf generated by Manager and saved in a certain directory. ---

How what, @melaibary? More than one thing was discussed in this thread. If you are asking about automatic signing of PDFs, that is not a Manager feature, but a function of the PDF generator you use. This forum is only for discussion about Manager. ---
