Hi there, @kausar-deltaacco. I'll share some information about why the net income is not matching between your balance sheet and profit and loss account.
The Balance Sheet report shows a net income for current fiscal year and it should match the net income on the Profit & Loss report. However, please know that it is a cumulative report that carries a beginning balance. There are times that the report will show a different net income even if the filters are the same. For other reports, the date range you choose only applies to net income and the specific account you select within the report.
To give you a clearer idea of why this happens, check out this article for more information: Differences between a Balance Sheet report and other reports
Moreover, you can export your report to Excel if you may want to add some details that isn't available within QuickBooks.
