In my Profit and Loss Report the Total of my income does not match when all my invoices are added together. Why is this?

Welcome to the Community forum, @Nicholas-Frost. I've got details about why the total income on your Profit & Loss (P&L) report doesn't match your invoice totals in QuickBooks Online (QBO).

Firstly, income represents all transactions and payments from your business operations, including sales revenue and service fees. These transactions include invoices and sales receipts. Thus, the total income shown in your P&L report doesn't match the sum of all your invoices. For a detailed explanation of transactions displayed in this report, you can check out this article: Profit and Loss Report in QBO.

Moreover, another factor affecting the P&L report is the date range and accounting method settings. Please ensure you've set the correct Report period and verify if you're using Cash or Accrual basis for accurate results. Please see the screenshot below for visual reference:

Moreover, the P&L report is a financial statement that outlines your business's revenue and expenses over a specific period. In QBO, you can also use this report to identify any missing income and expense transactions.
