My Customer Sales Summary and Proudct/Service Sales Summary report totals match but my Profit & Loss total Customer sales for the same period does not?

Hello sue-kyle,

It's important your Profit and Loss report totals are matching your sales reports. Rest assured, I'll be happy to give you a hand with this. QuickBooks Online is designed to bring simplicity to the way you handle your accounting. With our reports, you can easily bring your financials into focus. 

Great job on checking with the date ranges on your reports as that's one of the common factors which can cause discrepancies on your totals. Here are other factors to consider: 

• The accounting bases of the reports do not match. 
• Sales items point to incorrect sales accounts.
• The P&L report includes transactions that do not use items (e.g., the Expense on a bill or a journal entry).

It's important to check you're using the appropriate accounting method and you can check this using the steps below: 

1. Click on Settings ⚙, then select Account and Settings.
2. Navigate to the Advanced tab.
3. In the Accounting section, click Edit ✎ icon.
4. Select the Accounting method.
5. Click Save, then Done.

You can also adjust the accounting method from your reports. Once you have the report open, look for where it says Accounting method. From here you can select the method you'd like to use. It's vital you go through your reports and check if the transactions are recorded correctly. You can compare and contrast your Profit and Loss and sales reports to see if there are more/less transactions on them.

Give this a try and let me know how you make out. I'm here to help.
