payal, price negotiation is big issues for sales now a days.
i am agree with harish's view, you can also add and impliment followings:
1. Product knowledge of compititors.
2. Compare marits and demarits with your product.
3. Never disclose the price first, untill sales seems to close.
4. Also involve some techniqual/ manfacturing points in your presentation.
5. Listen carefully needs of the customer and then generate the need of your product.
6. Don't go for huge discussion with the customer.
7. Give the gud examples of branded product for price negotiations. (HUL - pureit)
8. Eliminates the doubts clearlly with examples.
9. If it is not possible to close sale at the time, keep his contact no. for further prospect.
10. Focus on Refences it could be generate more leads for you.
11. Also make a chart in number like lead conversion, price issues, product quality, area segment, type of customer, target customer and analyse the chart every last day of the week.
