For contracts of long period, high value, complexity of the performance increases, supplier risk rises in Fixed price contract. There are many variant of fixed price contract those are in specific scenarios to mitigate the risk.

Cost plus a fixed fee – allowable cost plus negotiated fixed fee
Cost plus percentage of cost – most undesirable as supplier has no incentive to control cost, higher cost means higher profit to supplier.
Cost plus award fee – if the supplier cost below target, supplier and buyer share profits. If the supplier cost is above target some portion of profit of supplier is reduced. Supplier can lose all its fee but not cost.
