An invoice question

[txkeyboards]

Hello everyone,

I am just trying to understand if there is anyway I can make Virtuemart to not create a new invoice whenever something has to change (zipcode/items/etc.). This inflated the number of products we actually sold when I tried to do a sales report. I just want the old one to be replaced if possible.
