My customers and invoices all disappeared! How do I get it back???

Hi mlamesse, 

Welcome to Community!  QuickBooks Online provides the features you need complete all of your daily bookkeeping tasks with ease.  I can see how having your customers and invoices disappear would be rather alarming.  I'll be happy to help so you're back on track with your work!

If you haven't done so already, I recommend clearing cache on your browser.  This is important to increase the performance of your system.  Once you've completed the process, log into your QuickBooks account using a private or incognito browser.  I'd also suggest trying other browsers such as Safari, Edge, Google Chrome or Firefox. 

If the issue persists, please don't hesitate to contact us so we can work with you in real time and take a deeper look into the situation from our end.

Feel free to reach back out with any other questions.  We'd love to help!
