Hey there, theotillotson.

Thanks for posting your question here in the Community. I want to make sure you're able to create a customer statement in QuickBooks Online.

As an initial troubleshooting step, I recommend clearing the browser cache first. The cache is in place to collect frequently used data to make loading web pages quicker and easier. If it becomes too full it can potentially cause certain viewing and performance errors within the system. Clearing the cache will remove anything that's preventing the statement page from load properly. Here's how to get this done if you're using Chrome for example:

1. At the top right, click More (three vertical dots).
2. Click More tools and then Clear browsing data.
3. At the top, choose a time range. To delete everything, select All time.
4. Check the boxes next to "Cookies and other site data" and "Cached images and files."
5. Click Clear data.

The following article provides similar steps for other browsers: Clear cache and cookies to fix issues when using QuickBooks Online

Please give these steps a try and then head back over to the statement page to see how things look. I'm only a comment or post away if you have any other questions.
