Hello, ajb_plumbing. Welcome to the Community.
Tracking your sales will provide a clear view of your business performance. We'll show you some of the ways you can track the rolling twelve-month sales total in QuickBooks Online (QBO).
Before we proceed, could you please confirm the specific area in QuickBooks where you previously saw the rolling twelve-month sales total? Any extra details, like a screenshot, would greatly help us better understand your concern and offer the most accurate solution.
In the meantime, you can head over to the Sales menu or create a customized sales report to find the data you need. To get the rolling twelve-month sales total, simply set the Date or Report period to Last 12 Months or use the Custom dates option to manually enter the date range.
Please see the attached screenshots below for your reference.
