I'm here to ensure that you can connect with our customer service representatives seamlessly, Kristi.
Beforehand, did you try the suggestion from the error message to update your billing details? If not yet, refer to these steps:
- Log in to your QuickBooks account.
- Go to the Gear icon, then Subscriptions and billing.
- Click the Pencil icon from the Payment method section.
- From there, update or re-enter your billing information accurately.
You can also access this link for additional reference about updating and handling your billing details: Manage billing, payment, and subscription info in QuickBooks Online.
If the issue persists, I recommend contacting our Customer Support Team again. Please know that our team's availability would depend on your QuickBooks plan.
For Simple Start subscribers, our experts are available from 6 AM to 6 PM PT from Mondays to Fridays. Meanwhile, you can reach them from 6 AM to 3 PM PT on Saturdays, and unavailable on Sundays.
Finally, I've included this resource you might find handy: Customize invoices, estimates, and sales receipts in QuickBooks Online. It can help you manage and personalize the displayed information on your customer transactions.
If you have follow-up questions about sending or managing your invoices, feel free to add a reply to this thread. We're always here to help.
