Původní text - Rumunsky - , cu confirmare pe bază de comandă fermă

It's only a part of a sentence, with no verb.
Perhape it would be much better like this:

"Este cu confirmare pe bază de comandă fermă".

Not necessary. It can be a text from an official document (he set a coma in front of the text). Like we have at the post "scrisoare cu confirmare", for example. I would let it as it is, it can very well be translated.

Thanks Andreea.
