Welcome to the Community, MG2024.
I'm here to address your ending balance inquiry in creating a vendor summary report using your QuickBooks Online account.
Generating a vendor summary report provides information regarding the vendors you're spending your money. This report contains a list of vendors and the total amount paid for a specific duration. You can use this report to calculate your expenses.
Furthermore, your ending balance in your vendor summary report isn't necessarily to be zero. The report shows all transactions for each vendor, whether paid or not, adding up to your report's ending balance.
In addition, here's an article to learn how to memorize a report authorized by saving it with its current customization settings: Memorize reports in QuickBooks Online.
Don't hesitate to ask follow-up questions concerning your vendor summary report or QBO-related inquiries. I'll be here to address them promptly.
