Dear sir how can I add digital signature and stamp in invoice and quotation pdf
not possible in Manager. you can use any pdf editor for the same.
@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 https://www.manager.io/guides/8941 and 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.
