Welcome to the Community space, Lloyd.
Yes, you can send an Invoice via WhatsApp. Here's how:
- Open the invoice you want to send in QuickBooks Online.
- Next to the Save and send button, click the small arrow and choose Save and Share (WhatsApp).

- Add your customer’s email if it's missing, then write your message.
- Click Share and Close. A new tab for WhatsApp Web will open, where you can select a contact and send the invoice link.

It's also worth noting that this feature currently only sends a link to the invoice, not a PDF. The mobile app option is also currently only for iOS. Please refer to this article for more information: Send invoices with WhatsApp in QuickBooks Online.
