Oversættelse - Italiensk-Engelsk - la firma di garanzia del negozio è fatta

Hi Efylove, Hi Miss, without further context I think what would sound better in English would be:
"The guarantee for the transaction is signed"

What do you think? Does that convey the meaning?

CC: Efylove

Yes, I think it could work.

Miss?

Literal meanings:
del negozio = of the shop
è fatta = is made

I think the translation is false.
First point "firma di garanzia" means "mark of guarantee". Indeed there is no signature made by someone !!!

I suggest the following translation :
"The mark of guarantee of the shop is made"
