4. Justify your request
You negotiation skills carry lots of weight while deciding the right amount of salary for a job. If you think you are the best possible candidate for a particular job then you can back up your demand by talking the whole world of possible things that you can do once you are on board. Some of these include: how you can add to the company's bottom line, what efforts have you done for your previous employer, what additional responsibilities you can take, and how your hiring will be an overall benefit for the company.
