Hi there, @Pearl189.
I'll make sure this matter is addressed timely to ensure you can access your customers in QuickBooks Online seamlessly.
To start with, it's recommended to use the Google Chrome browser and to install its latest version while using QuickBooks. Kindly read this article to learn more about a few things to consider for the best experience you can get: Why is QuickBooks Online Slow?.
Yes, @Fiat Lux - ASIA is correct, it's best to log in to your online account via the incognito or private browser. However, if you can confirm you've already followed the basic browser troubleshooting suggestion above, I suggest contacting our Customer Care Support.
With their tools, you can work with one of our specialists in creating a ticket via your email on file letting our engineering team investigate why you have experienced such inconvenience. You can do so by following the steps below:
- Go to Help.
- Select Search.
- Click Contact Us.
- Enter a few words describing how you're unable to access your customers' file in the What can we help you with? text area.
- Choose Chat or Callback to connect with our specialists online.
On that same page, I'm including this reference for the steps in creating a document for your customers showing what is due for a certain number of days: Create and Send Statements in QuickBooks Online. This way, you can remind them and let them prepare the needed payment for your invoices.
