Thanks for your help and expertise.

How do I "Void" an Invoice in QB 2020 Premier Desktop, as opposed to deleting it (Control D). Also, please confirm that "Voiding" a past Invoice posts the respective Sales Tax Credit to the next open Sales Tax filing period. I know how to "Delete" an invoice, but I wouldn't want to do that, as those sales details, unpaid or not, are an important record of what was done, info I wouldn't want to loose.
