One product that seems like a fit for the Zoho family is Acrobat. 

We need to prepare a compiled document to send to a customer. Some pages are PDFs, some are JPGs, some are selected cells from Excel or pages from Word files. Acrobat allows us to take all these different file types, turn them all into one document and reorder the pages, add notes or highlights, etc.  Then rolls the whole thing into one PDF that we can email as attachment. 

That seems like something Zoho would have. Does one of the products inside Zoho One already do something like this and I'm missing it? 

If not, it would be a great addition.
