Can I automatically send our company's W9 when I send an invoice to a customer?

Hello, @mpfralick.

I'd be glad to give you an insight about W9 in QuickBooks Online. 

The Form W-9 is a request for the TIN and certification of a U.S resident. Currently, sending the W9 forms automatically in QuickBooks Online is unavailable. 

What you can do is to get a downloadable form from the IRS website and manually email it to your contractors. Here's how:

1. Go to the IRS.gov website.
2. Click the Forms & Instructions tab.
3. Select Form W-9.

Once you receive their information, you can set up their account in QuickBooks. You may follow the steps outlined in this article to add a new vendor: How to add, edit, and inactivate contractors.

You also have an option to invite your contractor so that they are the ones who will enter their tax information.

Here's how: 

1. Go to the Workers tab located in the upper left corner.
2. Choose Contractors, then Add contractor.
3. Enter the contractor's name and email in the field, then tick the box below the email box.
4. Hit Add Contractor.

After that, let your contractors log in with their Intuit account if they have one or create a free account to share their tax info with you. Then, they'll enter their W-9 info and sign the form.

Feel free to let me know if you have additional questions. I'm always here to help. Have a lovely day.
