I know this hasn't been an easy process for you, 

Stomp Records. I understand how latency affects your navigation, and I want to make sure this gets resolved for you.

Since latencies in your company file persist, I recommend contacting our Customer Care Team. They have the necessary tools to review your account and further investigate the root cause of this issue. To do this:

1. In your QBO account, go to the Help icon and choose the Search tab.
2. Select Contact Us.
3. Describe your concern and click Continue.
4. Choose between Chat with us and Have us call you.

Also, you may consider taking into account the information shared by my colleague, jenop2 above.

In case you want to track and manage customer-paid invoices, you can record their payments to link the transaction to the original invoice. This way, your accounts stay balanced and accurate.

I'll be more than willing to provide additional assistance to any queries you may have when performing QuickBooks-related tasks. Feel free to mention me on this thread, so I can get you covered. Keep safe!
