Thanks for joining this thread, @JulioS. Let me provide some information about invoices in QuickBooks.

If you integrate Bluebeam with QuickBooks, and you are having issues with invoicing using the software, I recommend contacting them directly.

They have the right tools to check the preferences and help ensure that your invoices will not be garbled. 

Let me also attach this link to help you send a physical or PDF copy of a statement or sales form to your customer: Download and save invoices, other sales forms, and statements as PDF.

Keep me posted if you have additional questions about managing invoices in QuickBooks. I'll be happy to help you again. Stay safe!
