About invoice and quote new attachment

I have been download your desktop edition, but i want to know about invoice and quote when i create it already then view it again i saw on it have new attachment to upload file or picture but when i upload it already, then i email or pdf file is blank no see the file that i upload, why?

How can i upload stamp on it to saw it when my customer view it in pdf or email?

Manager has no way of knowing that you want to add an attachment to the email. If you want full control of emailing, it might be better to generate a PDF of the invoice. Then, separately, add it plus any other attachments you want to an email created in your email program rather than in Manager.[quote=“Nalyn, post:1, topic:7719”]

You cannot do this in Manager. But you can do anything your email program allows if you follow my advice above.
