Including a PDF attachment with customer statements allows recipients to seamlessly review their account activity in QuickBooks Online (QBO), Kinsm. I'll offer a workaround and guide you in submitting a feature request to our developers.

Currently, QuickBooks Online (QBO) doesn't have the option to attach PDFs to customer statements. Instead, you can download your customer statements and manually send them outside QuickBooks.

Here's how:

1. Go to + New, then Statement.
2. Tick the box beside the customer.
3. Select Print or Preview.
4. Click the download icon, then send the PDF directly to your customer.
   
   

We recognize how this option can help you seamlessly. I recommend sending feedback to our product engineers. It could lead to a feature enhancement, making the process more streamlined for you and other users in the future.
