Attaching documents from an iPad

I want to add a PDF file to a customer account on my iPad. my PDF files are stored in my goodreader app. Is there any way to attach a PDF from goodreader to a customer account on my iPad? I an accessing Zoho through the www.zoho.com website on my iPad, not the mobile site (because the mobile site does not communicate with Zhoh on my desktop). Thank you.
