The Most Favoured Customer Pricing Review Clause: What It Means and How to Negotiate It (2026)

What is a most favoured customer pricing review clause? A most favoured customer pricing review clause is the enforcement engine behind a best-price promise. A plain most favoured customer clause (also called MFN or best-price) says the supplier will give the buyer prices and terms no worse than it gives any comparable customer. The pricing review clause is what makes that promise real over time. It adds three mechanics: a periodic review of the supplier's pricing, a true-up that refunds or credits any amount the buyer overpaid, and an audit right so the buyer can verify the supplier kept its word. The distinction matters. A bare best-price promise is easy to give and hard to check. Without a way to review the supplier's other deals, the buyer simply has to trust that it is getting the best price. The pricing review clause replaces trust with a process: the supplier confirms, on a set cycle, that the buyer still has its best terms, and if not, the gap is corrected and can be audited. This page is about that review, true-up and audit machinery, not the general best-price promise itself. This article is general guidance, not legal advice. Best-price clauses can raise competition-law issues in some markets, so have a qualified lawyer review any clause before you rely on it. ## The three mechanics - Periodic review and matching. On an agreed cycle (for example every quarter or year), the supplier reviews whether it has offered a comparable customer better pricing, and if so matches it for the buyer going forward.

• True-up. The retroactive correction. If the review shows the buyer overpaid against the better price during the period, the supplier refunds or credits the difference. This is the part suppliers most often try to remove.
• Audit right. The buyer may appoint an independent auditor to inspect the relevant pricing records and confirm compliance, usually under confidentiality and within set limits. Guidance on these clauses stresses that the better term should apply as automatically as possible, backed by an audit right to verify it, because a promise with no check is weak. Government and defence buyers sometimes go further and require the supplier to certify its most favoured customer price on a form, as the US Department of Energy's Pantex site does. ## Sample wording ``` MOST FAVOURED CUSTOMER PRICING REVIEW 1. The Supplier represents that the prices under this Agreement are no higher than those it offers to any comparable customer for comparable volumes, term and scope (a "Comparable Customer"). 2. Within [30] days after the end of each [calendar quarter], the Supplier shall certify in writing whether it has offered any Comparable Customer more favourable pricing. If it has, those prices apply to the Buyer with effect from the date they were first offered to that customer. 3. True-up. The Supplier shall refund or credit the Buyer the difference between the prices paid and the more favourable prices for the affected period within [30] days of the certificate. 4. Audit. On [20] Business Days notice, not more than [once] a year, the Buyer may appoint an independent auditor (under confidentiality) to verify compliance with this clause. If an underpayment of more than [2]% is found, the Supplier bears the cost of the audit.

- a wide comparison set and all material commercial terms covered, not just headline price, so the benefit cannot be routed around through rebates or bundles;
- a real audit right with teeth, including the supplier paying for the audit if a material shortfall is found. **The supplier usually wants:** - a narrow comparison set limited to truly comparable customers by volume, term and segment, excluding affiliates, pilots, one-off discounts and strategic deals;
- the better price to apply only going forward on the buyer's election, with no retroactive true-up, or a capped one;
- tight limits on audit frequency and scope, strong confidentiality, and a sunset so the obligation expires before the contract does. The comparison set is where the clause lives or dies. A promise of the "best price to any customer" is usually unworkable and will be resisted; "best price to a customer of comparable size, volume and term" is far more enforceable. The retroactive true-up is the other main battleground, because it is what turns a forward-looking promise into money back for the past. ## A note on jurisdiction Most favoured customer clauses are not only a contract-drafting question; in some markets they attract competition-law scrutiny, because wide best-price or price-parity obligations can soften competition between suppliers. Enforcers in the EU, the UK and elsewhere have challenged certain parity clauses, particularly in online platform markets, and the analysis varies by jurisdiction. In India such clauses are generally a matter of contract under the Indian Contract Act, 1872, but can engage the Competition Act, 2002 where they risk an appreciable adverse effect on competition. Because both the commercial enforceability and the competition-law treatment vary by jurisdiction, have the clause reviewed locally rather than assume it is safe everywhere. ## Where one contract workspace helps A pricing review clause is only worth having if the reviews, certificates, true-ups and audit windows actually happen on schedule. The quiet work is tracking each review date, chasing the supplier's certificate, checking the true-up maths, and keeping the comparison-set definition consistent across your supply contracts. Miss the cycle and the clause quietly delivers nothing. That cycle is easier to hold when drafting, reviewing, tracking and governing the contracts that carry a pricing review live in one AI workspace tuned to your company, so a review cycle, a certification deadline and an audit window stay visible rather than lapsing. [Adira](https://adiralaw.com) is designed to work this way across your supply contracts. The explanation above is enough to negotiate the clause on its own; a workspace makes sure the review right is used every cycle.
