Fixed-Price Contract

A fixed-price contract is a contract in which the price is not adjusted based on the contractor's costs in performing the work. NATO's procurement manual states that a firm fixed-price contract places responsibility for all costs, and the resulting profit or loss, on the contractor. NATO Procurement Manual

In Canadian federal contracting, fixed price is most often described as a basis of payment. CanadaBuys explains that it gives price certainty for the duration of the contract, and the contractor is paid a definite sum for the work regardless of the costs it incurs. CanadaBuys: Fixed price

How NATO defines firm fixed-price and its variants

NATO's competitive procurement procedure defines a fixed-price contract as one where the price is not subject to adjustment based on the contractor's performance costs. NATO procurement procedure The same documentation recognizes more than one form. A firm fixed-price contract allows no adjustment for the contractor's cost experience, while a fixed price with economic price adjustment permits specified adjustments for significant, externally driven price fluctuations.

Other fixed-price variants can be used depending on the requirement, the risk and the contract terms. Terms such as firm price, firm fixed price, ceiling price and fixed price with economic price adjustment are not necessarily interchangeable. The solicitation and the contract clauses decide whether any adjustment, ceiling or incentive applies.

Fixed price as a Canadian basis of payment

CanadaBuys lists three fixed-price options available to federal contracting authorities: fixed-price competitive, fixed-price non-competitive, and fixed price with economic price adjustment. CanadaBuys: Fixed price

• Fixed-price competitive: the price is established through competition among compliant offerors.
• Fixed-price non-competitive: the price is negotiated before the contract or amendment is issued.
• Fixed price with economic price adjustment: the price is fixed, subject to a stated adjustment mechanism.

When fixed pricing fits and when it does not

CanadaBuys advises using fixed pricing when the requirement, scope, outputs, level of effort, schedule and costs are sufficiently defined and stable, and when it is appropriate for the contractor to bear cost uncertainty. It also states that fixed pricing may be unsuitable for procurements with highly uncertain or variable scopes, including those involving innovative or untested technology. CanadaBuys: Fixed price

For bidders, the practical reading is simple. A well-defined deliverable with a stable schedule is a natural fit. A loosely defined scope is a signal to look closely at how the buyer has allocated risk.

Standard clauses and defence contracts

Federal solicitations point to standard clauses for fixed-price arrangements. One CanadaBuys-hosted solicitation states that Standard Acquisition Clauses and Conditions (SACC) Manual clause C6000C is inserted by reference for firm-price and ceiling-price contracts.

A fixed-price basis can also appear in defence solicitations, but the pricing basis and the defence designation are separate questions. CanadaBuys states that a contract awarded on behalf of the Department of National Defence is not automatically a defence contract. The technical authority determines whether the requirement qualifies as one under the Defence Production Act. CanadaBuys: Defence contract and defence supplies

What it means for a supplier bidding on Canadian public contracts

Under a fixed-price basis, your price is the price. Ordinary cost overruns are not automatically reimbursed, so the risk of underestimating sits with you. Before you submit, take these steps:

• Price the full scope of goods or services exactly as the solicitation describes it.
• Identify foreseeable risks and build them into the offer.
• Read the resulting contract clauses for any economic price adjustment, ceiling price, incentive, option or amendment provisions.
• Plan to meet delivery, technical, reporting, inspection and acceptance requirements within the fixed sum.

The term alone does not tell you whether price adjustments, claims or amendments are available. The solicitation and the incorporated clauses do, so read both before you commit to a price.
