How do I attach my W9 to my invoice when sending to a client?

Hi there, @witherjd.

I know that being able to attach your W-9 to a client is important. I want to make sure you have the information on how you can go about doing this. What I can recommend is to export the invoice. Then, manually send it to your customers outside of QuickBooks Self-Employed. You can attach your W-9 to the email. 

Here's how to export:

1. Go to the Invoices tab.
2. Click the drop-down arrow under the Action column.
3. Select Export as PDF.

More details about creating and managing invoices are thoroughly discussed in this article: Create an invoice in QuickBooks Self-Employed.

I'll ensure to send feedback or a feature request about being able to add an attachment to invoices. Our engineers review all the feedback we receive to ensure we’re meeting the needs of our customers. You can also share your thoughts and ideas through your account. 

Here's how you can leave feedback:

2. Type and enter "feedback" into the chat box.
3. Follow the prompts to leave feedback.

If you have any other questions, just let me know and I'll be happy to help. Thanks again for reaching us and have a wonderful day!
