[Star Wars] Do bounty hunter droids hunt for their own desire or are they owned by someone?

For example, the IG units in ESB and Mandorian. Are they hunting of their own volition, as in they accepted the contract and if they'd succeeded, would've received the paycheck themselves to spend as they wanted? 

Or were those IG units owned by someone and if they had succeeded, the person who owned the droids would receive payment?

In legends most droids were owned and maintained by a corporation or various factions that wanted a perfectly loyal killing machine.  Some like ig 88 were sapient or nearly sapient and ig88 hunted for personal profit and used said profit for self improvement.  Ig 88 planned on becoming the perfect machine but that may be different from other droids that operated without a master.  In canon it appears that all ig units are operated by a singular company or group for bounty hunting.
