Why is there is a balance forward on customers statement when there are no invoices prior the the date parameters I specified?

Let me help with your question about statements in QBO, todd55.

The Balance Forward line that you can see in your customer statement is the total amount of open invoices prior to the date that you selected. Although the Balance Forward Type of statement only lists the invoices and payments for a specific date range, it will also include the balance of old transactions. 

Here's an article for more details: Create and Send Customer Statements in QuickBooks Online.

I'd also like to share a few more guide articles and reference just in case you might need them in your future tasks:
