I need to attach a PO to my invoices when I send them, is this possible on QuickBooks?

Welcome to the Community! I'm pleased to assist you in attaching a purchase order to your invoices in QuickBooks.

Yes, you can attach a purchase order (PO) to an invoice when you send it through QuickBooks. To do this, you'll need to download a PO then attach it to an invoice. I'll show you how to do it below.

First, here's how to create a PO and download it:

1. Go to the +New button.
2. Select Purchase order under Suppliers.
3. Fill out the form.
4. On the bottom of the screen, click Print.
5. Press Download, and then save the file to your device.

Afterwards, you can create an invoice and attach the PO by following the steps below:

1. Go to the +New button.
2. Select Invoice under Customers.
3. Fill out the form.
4. At the bottom part, drag the downloaded file in the Attachments field.
5. Tick the Attach to email option.
6. Send the invoice by clicking Save and send.

Once done, your customer will receive a copy of the invoice as well as the attached PO.
