In a negotiation for a new contract, the supplier suggests the buyer to shorten payment period from 45 days to 15 days because they are investing in new facilities to expand the supply capacity. The buyer replies that she can only sign off the deal if the payment period is 30 days ormore since it often takes at least 30 days for her company to collect the payment from customers. A permission from senior management is required for this suggestion. In order to ensure that supplier understands the matter, she reiterates it throughout the meeting. Which tactics is she using?

1. Outrageous initial demand

2. Salami slicing

3. Lack of authority

4. Broken record
