Is it possible to put a password protect on the PDF invoices and quotes? I know i am able to do this manually on other software but i need each user to do this?

Hello there, VdPSAR.

In QuickBooks, there is no built-in feature to password-protect PDF invoices and quotes. However, you can use a third-party application to add a password to protect those documents. 

Then, find encryption tools that can help you send protected files to your customers, you can visit our App Store.  It'll help you enhance the security of your invoicing and quoting process. 
 

We also have a separate forum called Intuit Developers. You can connect with experienced developers who can provide guidance on the best third-party hosting applications for your needs.

Additionally, you can personalize and add specific information to your sales forms in QuickBooks, you can visit this article for more details: Customise invoices, quotes, and sales receipts.
