Effective negotiation preparation requires buyers to align pricing mechanisms with cost forecasts and risk exposure. Since copper prices are forecast to fall, fixing them would disadvantage the buyer; a variable price allows the buyer to benefit from market reductions. Conversely, where plastic component costs are expected to rise, fixing prices protects the buyer from inflationary increases. CIPS highlights the importance of selectively applying fixed and variable pricing to manage risk intelligently rather than adopting a single approach across all components. This mixed strategy demonstrates strong commercial awareness and supports value-for-money outcomes over long-term contracts.
