Thanks for getting in touch with the Community, bosettilawncare.
I can certainly understand how an ability to select specific customers to receive texted invoices could be useful and have submitted a suggestion about it as of today.
You can also submit your own feature requests while signed in.
Here's how:
- Use the Gear icon, then go to Feedback.
- Enter your suggestion(s) in the Have feedback? window.
- If necessary, attach a file with your Camera icon.
- Select Next.

Your feedback's definitely valuable to Intuit. It will be reviewed by our Product Development team and considered in future updates. You can stay up-to-date with the latest news about your product by reviewing Intuit's Product Updates webpage.
I've also included a detailed resource about working with invoices in the app which may come in handy moving forward: Receive an invoice payment using the QuickBooks Online mobile app
I'll be here to help if there's any additional questions. Have an awesome Wednesday!
