Why will the customer's payment be automatically closed

Hi there, userhello13.

I'd like to help with your question about customer payments. Are you referring to the status of your invoices? If so, they will be marked as paid and will automatically close as soon as payments are applied. Check out this article for additional details: Record Invoice Payments In QuickBooks Online.

If you're using PayPal to receive payments from your customers, they will be linked to the invoice once the transactions are imported. Then, the invoice will automatically close as well. Here's an article for more details: Accept Card Payments With PayPal App FAQ.

Let me know if you need anything else. We're always here to help.
