Customer statement reflects incorrect invoice amount

Hello there, @LuckyDogAR. I'll ensure to get this sorted out on why the customer statements reflect the incorrect invoice amount.
 

Before I can do that, I'll need more details about your concern. I want to know the statement type you run and send to your customer. You can also provide us a screenshot so we can check the cause of the incorrect amount. Any additional information will be a great help in resolving your concern.
 

I'll be waiting for your reply in the comment section. Take care always!

Thanks for the screenshots, LuckyDogAR.

One possible cause why the amount is different is if the invoice was edited after the statement was printed. You can check out the Audit Log report to see if that's what happened.

The report also tracks the following information: 

• The date of any change to your books
• The name of the user who made the change
• The type of change or event
• The name of any customer or vendor related to the change
• Any original transaction date and amount

Let me share these steps on how you can run the report: 

1. Go to the Gear icon and select Audit Log.  
2. Click the drop-down list in the Date Changed section and select Custom.
3. Select a date when the invoice was possibly edited.
4. Look for the transaction and check if you can see an event that says "Edited".
5. Click the View link under the History column. This will give you more details about the changes.

Here's an article about this feature for more details: Use the Audit Log in QuickBooks Online.

If the transaction was not edited, we'll have to take a closer look at the transactions to determine why the amounts are not the same. 

For us to do that, I would recommend reaching out to out to our chat or phone support teams. The can screen-share with you and gather more information to sort this out. Here's how to reach out to them:
