How can i find out the dates reminders were sent for late invoices

Hi there, @aliskus-live-com. 

Thanks for posting your first concern today. The invoice reminder feature is only available in QuickBooks Online. 

I fully understand wanting an invoice reminder in QBSE. I'd be happy to share this suggestion with our development team. In the meantime, you can also share your suggestions by clicking on the Company Gear icon and selecting Feedback.

You can check out this link for more details: Send invoice reminders automatically or manually in QuickBooks Online.

If you have any other concerns, don't hesitate to let us know. Thank you for visiting the Community!
