That kind of thing can be created fairly easily with a macro. The only reason for the macro is that you want the current date & time; otherwise you could just save your 'Paid' stamp as a custom watermark and use that whenever it's needed. No additional software required.

Thank you again for your response, which does appear to provide a solution to my problem.
Re your suggestion, is this something that a retired Marine engineer, who has limited computer knowledge, action himself? If the answer is no, can you point me in the right direction for someone I could commission to create this for me.
