He accounts payable amount on the balance sheet and the vendor summary report are discrepancy.

Welcome to the Community, Shehani.

I can help you with information about Accounts Payable reports and Vendor Balance Summary reports in QuickBooks Online (QBO).

To make sure the balances match, check that the Report periods are the same for both the Accounts Payable report and the Vendor Summary reports. Also, ensure that the Aging method is set to either the Current or Report date for both reports. 

Additionally, ensure that the number in the Days per ageing period field on both reports is the same. After adjusting the settings, compare both reports again and verify the balances.
