Use Google Forms and have the result sent to a Google Sheet. Generate the invoice as a Google Doc using Google Apps Script pulling from the Google Sheet. I believe GAS will let you turn that Google Doc into a PDF and attach it to an email draft in the office person’s inbox. If somebody needs to edit something, let them edit the Google Doc and build a Google Docs extension that gives them a little button that lets them regenerate the PDF. Or they can just save it from the Google Doc themselves. https://www.google.com/script/start/ https://www.google.com/script/start/ The documentation is quite good.
