Reconciling a Bank Statement is different from reconciling a Supplier Statement, Andy.
To reconcile a Supplier Statement, you can run a Supplier Report in QuickBooks Online (QBO) and compare it with the vendor's statement. This helps you check that all bill payments and credits are correct. Here's how:
Navigate to the Reports menu.
In the search box, type Transaction List by Supplier.
Filter the dates in the Report Period.
You can review the vendor balance to confirm that your current amount is accurate, and you can filter the list if needed.
