Using incentives to make the team work

I think my position is very different, I earn an commission on my sales and free to get as many sales as I want, so free to pay myself what I want, plus earn two monthly bonuses one based on my own sales and another on the total sales of my group. In Network Marketing the companies offer incentives to attract their independent Sales teams to increase business for the company, in return we can earn more money and be rewarded with gifts, holidays, cars whatever the company is offering. Plus it helps to increase our own individual businesses. So maybe incentives don't work or are not required in some industries but in Network Marketing it has helped to greatly increase sales across the UK. 

The only incentive I use is, is that everyone can go home early once the work has been done... And I might buy everyone lunch...
