Thanks for this amended report, do you have the backup (invoice for the cheap model) as well.
From Tanaporn's email, we bought DELL computer, which has the higher quality but cheaper price than the one proposed in the budget plan.
Do you mean the document of the previous model or the one we bought? For the current one, the office always keeps both paper and electronic files.
I am talking about the paid invoice for the computer. Have you paid the vendor or are these reports on an accrual basis. Thanks
