Commercial negotiations on prices cover a range of aspects including pricing arrangements.

Afixed price agreementprovides the buyer withcost predictability. Once the price is agreed upon, the buyer is insulated from any cost increases on the supplier's side. The supplier bears the risk of fluctuating input prices, which simplifies cost control and contract administration for the buyer.

“With a fixed price arrangement, the buyer is protected from future price increases and does not need to monitor the supplier’s ongoing costs. This is particularly useful for budgeting and forecasting.”
