I need to affix a Purchase Order for a new client on a invoice?

Welcome to the QuickBooks Community, tribalzone875. Let me help you affix a Purchase Order on an invoice in QuickBooks Online.

If you mean to attach a Purchase Order to the invoice, you can do so at the bottom part of the Invoice page. From there, you can upload the PO file from your PC.

Here's how:

1. Sign in to your QuickBooks account.
2. Open the Invoice page and scroll down to the bottom part.
3. Click Attachments.
4. Go to the file location of the PO.
5. Upload the PO and click Open to upload.

However, if you're referring to converting or linking a PO to an invoice, this is currently unavailable in QuickBooks. You can only add an accepted purchase order to expenses, bills, or checks. You can open this article to see extra details: Add purchase orders to expenses, bills, or cheques in QuickBooks Online.

For now, I recommend visiting the Apps menu within QBO or in our QuickBooks Apps site for any recommendations we can integrate into the platform. This way, it'll help you turn a PO into an invoice transaction.

Lastly, refer to this article if you need steps on how you can personalise and add specific info to your sales forms: Customise invoices, quotes, and sales receipts in QuickBooks Online.

Please leave a comment if you have more questions about invoices or anything else. I'm always around to assist, tribalzone875. Take care.
