Account management

It isn't available in QBO however, here is my easy workaround.  

1) Customize your report to remove all footer fields and export file to PDF.

2) Open in Adobe Acrobat and go to Tools - Edit.

3) Select Header & Footer - Add.

4) In the Center Footer Field input your desired verbiage.  You may also want to change font details depending on your QBO Report Settings.

5) At the top of the entry screen select save settings and name your setting whatever you prefer.  I use "QBO Financial Statements".

Steps 4 & 5 will only be needed the first time in order to setup the template.  Once it is in Acrobat you can then select the saved footer after step 3 and it will automatically populate the other fields.  This template is user specific for Adobe and will be available to use on any reports.  The final template will look something like this...

Hope this helps!
