Cost-Plus Contract
What is a cost-plus contract?
A cost-plus contract is an agreement in which the owner reimburses the contractor for the actual cost of the work — labor, materials, and equipment — plus an added fee for overhead and profit, rather than paying a single fixed price.
It is used when scope is uncertain or likely to change, since it does not require pinning down a final price before the work is understood. The fee may be a fixed amount or a percentage, and contracts often set a guaranteed maximum price to cap the owner's exposure.
Cost-plus shifts more risk to the owner and puts a premium on transparent, well-documented costs. Keeping an accurate estimate and clean cost tracking is what makes the arrangement work for both sides — the kind of cost clarity Quotr is built to provide.
For contractors, cost-plus reduces the risk of underbidding uncertain work. For owners, it trades price certainty for flexibility, so it demands trust and good cost records.
Why it matters
A cost-plus contract removes the guesswork of a fixed bid but hands the owner the cost risk. Both sides depend on accurate, transparent cost data to keep it fair.
