A » A stipulated sum (lump sum) contract is where the contractor agrees to complete the project for a fixed price, covering all costs and profits. In contrast, a Cost-Plus contract involves the owner paying the actual costs incurred by the contractor plus a fee or percentage for profit. This provides flexibility for changes but may lead to higher overall expenses for the owner.
