Just thinking out loud here but the particular case of inventory of an item should be possible to decrement/increment using a PN-Counter CRDT as long as you are fine with eventual consistency. Of course there's a risk of overcommitment which has to be considered but such risks usually exists in commerce any way due to or factors.
