Thanks for chiming in on this thread, @jojo1616.

At this time, the option to send an invoice via text message directly isn't available. However, you can send an invoice link to your customers over SMS so they can view and pay their invoice using the Save and share link option. 

In the meantime, I suggest utilizing a third-party app that can directly send invoices to your customers using text messages. Simply hover over to the Apps menu inside your QBO account and look for an app.

We also recognize how beneficial sending an invoice link directly via SMS is for you and your business. While this option is unavailable, I recommend sending your feedback to our Product Development Team so they can review it and perhaps consider adding this in our future updates. Here's how:

1. Log in to your QBO account.
2. Go to the Gear icon, then tap Feedback.
3. Enter your comments or product suggestions.
4. Then select Next to submit feedback.
