When a reminder is sent it records as last delivery, can I find out a date that the original invoice was sent?

Hello Gillian

You can go into the invoice and then on the black banner at the bottom go to more and then audit history  it will show if you click on the date in the sent part when it was sent or on the invoice itself if you scroll down on th left side by the attachments it should have also have the sent history

Thanks
