Don't think my invoices are sending to new customers

This isn't a common occurrence, monty.

I'm here to share troubleshooting steps to ensure your new customers can receive the invoices.

If you recently migrated from QuickBooks Desktop, we may need to reset your email address to refresh the info in the online version. Here's how:

1. Go to the Gear icon, then select Account and settings.
2. Select the Company section, then click Edit ✎ in Contact info.
3. Review each email address and make changes as needed.
4. Select Save, then Done.

If not, have your customer check their junk or spam folder. The transactions could be stored at that location. Otherwise, I recommend clearing and re-entering your email address. I'll show you how:

1. From the Gear icon, select Account and settings.
2. Select the Company section, then click Edit ✎ in Contact info.
3. Clear the Company email field and enter the desired address as is, even if it appears correct. (Be sure not to use extra characters or spaces before, within, or after the address you enter).
4. Select Save, then Done.
5. Send yourself a test transaction.

In case none of these fixes the issue, I suggest performing Solution 3 in this article: Troubleshoot if Customers Aren't Receiving Emails.

Meanwhile, we can send your customer invoices link via SMS or other messenger services. To get this, open the transactions. Then, select Save and Share link under the Save and close drop-down menu. 

Aside from that, we can also use your Gmail address to email the invoices or print and send them via mail.

Furthermore, I've added an article that'll help you gently remind customers about invoice due dates to ensure you'll receive payments on time: Send Invoice Reminders Automatically or Manually in QuickBooks Online.
