Currently, when one completes our conference registration form, we manually prepare and email his/her invoice. We use Google Forms for this purpose. Does anyone know of a way that we could streamline this process by having an invoice automatically prepared and emailed to the submitter? Is there on online service that is recommended for this purpose? Thanks.
Check out http://www.appvita.com/, just search for invoice and you will get a whole bunch to choose from
How can I use PHP for this purpose? I have a website designed in PHP. However, my knowledge of web design is very limited. Thanks.
If your knowledge is very limited and you don't want to hire a coder, this maybe help: http://css-tricks.com/html-invoice/. It easy to understand.
