Most Favored Nation (MFN) Clause Explained: What It Means and What to Change
This page is general information, not legal advice.
A most favored nation (MFN) clause, also called a most favored customer clause, is a promise that you will give one customer terms at least as good as the ones you give anyone else. It usually covers price, and it can also cover discounts, payment terms, features or service levels. Large clients often put it in supplier, agency and freelance contracts so they never pay more than a competitor. The idea sounds harmless, but a broad MFN can quietly limit your pricing with every other client, force refunds and expose your books. This page covers six ways MFN clauses often move risk onto the supplier. For each one you get an illustrative example, why it matters, and wording you can propose. Whether and how these clauses can be enforced, including under competition rules, varies by jurisdiction.
The example clauses below are illustrative. They are not taken from any real company's contract.
1. An MFN that covers every customer and every deal
A typical clause might read: "Supplier represents that the fees charged to Client are and will remain no higher than the fees Supplier charges any other customer for any services."
Why it works against you
"Any other customer" and "any services" ignore the reasons prices differ in real life. A bigger client, a longer commitment, a nonprofit rate or a one-off launch discount can all count as a better deal. Once that happens, this client can claim the same price even though it isn't buying the same volume or scope. In practice, you may stop offering discounts to anyone just to protect one contract.
What to ask for instead
Sample wording to propose: "This section applies only to customers purchasing substantially similar services, in similar volumes, for a similar term. Discounts for nonprofits, pilots, promotions and bundled packages are excluded."
2. Automatic, retroactive price matching and refunds
A typical clause might read: "If Supplier offers more favorable pricing to any other customer, Client's fees shall be automatically reduced to match, effective from the start of this Agreement, and Supplier shall refund any difference."
Why it works against you
An automatic reduction means you don't get a chance to explain why another deal is different. Retroactive refunds make it worse, because one new discount can turn into a repayment covering months or years of past invoices. That can wipe out the profit on the whole engagement. See late payment fee clauses explained for how money terms like this can pile up.
What to ask for instead
Sample wording to propose: "If Client believes a more favorable price applies, it will notify Supplier in writing. Any agreed adjustment applies only to fees invoiced after the date of that notice. No refunds apply to earlier periods."
3. A duty to report your other deals, plus audit rights
A typical clause might read: "Supplier shall notify Client promptly of any more favorable terms offered to any third party and shall permit Client or its auditors to inspect Supplier's records to verify compliance."
Why it works against you
To prove compliance you may have to reveal other clients' pricing, which can breach your confidentiality promises to them. Open-ended audit rights also cost you time and admin, and they give a large client a detailed view of your business. See confidentiality survival clauses explained.
What to ask for instead
Sample wording to propose: "Supplier will confirm compliance with this section in writing once per year on request. Any review is limited to an independent auditor bound by confidentiality, at Client's cost, and no third-party customer will be identified."
4. MFN that reaches beyond price
A typical clause might read: "Client shall be entitled to terms, conditions, warranties, service levels and payment terms no less favorable than those granted to any other customer."
Why it works against you
Contract terms are negotiated as a package. Another client may get longer payment terms in exchange for a higher rate, or a stronger warranty because it pays for premium support. A clause like this lets this client cherry-pick the best piece of every deal without taking on the trade-offs. It can also clash with other promises you've made, such as exclusivity. See exclusivity clauses explained.
What to ask for instead
Sample wording to propose: "This section applies to the per-unit price only. If Client wants another customer's terms, it must accept that customer's full set of commercial terms, including price, volume, term and payment schedule."
5. A price parity rule across your own channels
A typical clause might read: "Supplier shall not offer its products or services at a lower price through any other channel, including Supplier's own website, than the price offered to Client or Client's users."
Why it works against you
This version, often called a parity clause, stops you from selling more cheaply anywhere else, including directly to your own customers. Platforms, marketplaces and distributors sometimes use it to keep you from undercutting them. It can stop you from running your own promotions and push prices up for everyone. Some jurisdictions restrict these clauses under competition rules, so ask a qualified lawyer whether yours can be enforced.
What to ask for instead
Sample wording to propose: "Supplier remains free to set its own prices on its own website and in its direct sales. This section applies only to prices offered to other resellers of the same products."
6. No end date and no exit
A typical clause might read: "Supplier's obligations under this section shall survive any expiration or termination of this Agreement."
Why it works against you
An MFN that survives the contract can limit your pricing long after the client has stopped paying you. Combined with automatic renewals, it can last for years without anyone reviewing it. See auto-renewal clauses explained and automatic price increase clauses explained.
What to ask for instead
Sample wording to propose: "This section applies only during the initial term of this Agreement and ends automatically on expiration or termination. Either party may remove this section on renewal by written notice."
Also worth a look
MFN clauses often sit next to other terms that shift money and risk, such as long payment periods (see contractor payment terms red flags) and broad indemnities. If you work with agencies or on retainer, check agency retainer agreement red flags, and for general service work see freelance contract red flags.
