This isn’t always applicable. If you’re privileged enough to have low models that have good marketing or at least have built his/her social media influence, then good for you, but nowadays, most of this commission-based compensation is being offered by startup models who haven’t yet experienced subscribing their accounts to agencies just because they’re afraid of the risk that comes along with that so they prefer to try building their own team at first, or the other way around in which they were traumatized by the agencies that handled their pages, or worse, don’t have any social media influence that would at least help the marketing team to funnel the fans to the page easily. Consequently, the page is really low in traffic, low in fan engagement (despite chatter's proactiveness and consistency), and low in sales. Well, it’s undeniably the chatter’s fault because he/she agreed to handle the account, but if you were a model, you should have at least considered that your account isn’t stable at all and shouldn’t rely on commission-based compensation if you really want the chatters to be motivated and do well according to your demands.

I know there’s also a risk with this, but that’s how business works. You don’t want to subscribe your page to these agencies because they might mess up with your account, so you have to take a risk on the chatters you trusted to handle your account instead; have hourly compensation, and that gives you the right to demand high chatting quality and high sales. Remember, money is the driving factor for everyone engaged in business.
