Try changing it in both places below then reuploading (you may need to restart QW).
Utilities > Change Registration Info
Tools > Options > Company
Alternatively, you can simply replace [QV_PreparedByCompany] with "JustTypeInTheWordsYouWantToShow"
Thank you, Change Registration Info was my missing link

I need to change the company name on our QV templates, I think I'm looking for the [QV_PreparedByCompany] field. Can somebody let me know where to amend that?
