Why the total of account revenue and total of Income by customer Summary were not the same ?

Hi there, somsanithph-phon.

The total account revenue and a total of Income by customer Summary should the same. With this, it could be the date range and the accounting method of the reports are not the same. I'd suggest opening both reports and choosing the same accounting method and period. You'll also have the option to customize these two statements so you can easily differentiate the totals.

Here's how:

1. Click Reports at the left panel.
2. Choose the report in the search bar.
3. Select the date range in the Report period and the accounting method.
4. Click the Customise button and filter the report to view the data that you want to see.
5. Hit the Run button.

For additional information about customizing a report to focus on the details that matter to the data you want to view, you can click this article: Customise reports in QuickBooks Online.

If the issue persists, I'd suggest logging your account and running a report using a private browser or incognito. This way, we can isolate this for a possible browser-related issue. You can use any of these keyboard shortcuts:

• For Internet Explorer of Firefox, press Ctrl + Shift + P.
• For Chrome, press Ctrl + Shift + N.
• For Safari, hold down Command + Shift + N.

If it works in incognito, I'd recommend clearing the cache of your regular browser. This removes the history or log of sites so you can start with a clean slate. If the steps above didn't work, use another supported browser as an alternative.
