Thanks for joining us here in the thread, Maggie.
To provide an appropriate resolution, may I kindly ask if you're using an integrated app? This could be why the system generated a monthly invoice for your client.
If not, I'd recommend reaching out to our QuickBooks support team for further investigation. They have the necessary resources to look into this matter in a safe environment. This way, they can open a new ticket for you and sign you up for the notification list to receive email updates.
Here's how:
- Sign in to your QuickBooks Online company.
- Go to the Help icon.
- Click the Search tab and select Contact Us.
- Enter a summary of your concern and click Continue.
- You can either choose Chat with us or Have us call you.
Additionally, I'm adding this resource you can browse for you to be able to have more tips and resources while working with QuickBooks in the future: Help articles, video tutorials, and more.
I'll keep an eye on this thread for any additional queries you may have when managing invoices. You can reply to this post, and I'll make sure to get the help you need. Keep safe.
