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

What is a most favoured customer clause? A most favoured customer clause is a promise by a seller that a particular buyer will get terms no less favourable than the seller gives to other comparable customers. If the seller later offers someone comparable a lower price or a better term, the protected buyer is entitled to the same. The clause ties the price in one contract to the deals the seller strikes with third parties. It goes by several names. "Most favored nation" (MFN) is the old label, borrowed from treaties between states. "Most favoured customer" is the commercial, plain-English version. Some practitioners call it a "parity" or "best prices" clause. They describe the same idea. This article is general guidance, not legal advice. MFN clauses touch competition law in some sectors and markets, so have a qualified lawyer review one before you rely on it. ## What the clause actually covers Price is the usual focus, but a most favoured customer clause does not have to stop at price. It can reach other terms too, such as discounts, payment periods, service levels, product access or product quality. Because it can sweep in so much, good drafting names exactly which terms are covered rather than leaving "terms" open. The clause lives or dies on three definitions: - The comparison group. Which other customers count? "Any customer" is very wide and hard to administer. "Any customer of comparable volume and type" is narrower and more realistic.

• The lookback and forward window. Does the promise cover deals the seller has already signed, future deals, or both, and for how long?
• The audit right. How does the buyer check that the seller is keeping the promise, given the buyer cannot see the seller's other contracts? ## Sample most favoured customer clause Copy the block below and fill the bracketed fields. This is illustrative drafting, not a precedent for a specific deal. ``` MOST FAVOURED CUSTOMER 1. During the Term, the Supplier shall not provide the Products or Services to any Comparable Customer on terms that are, taken as a whole, more favourable than those given to the Customer under this Agreement. 2. "Comparable Customer" means a customer purchasing [the same or substantially similar Products or Services] in [comparable volumes] on [comparable commitment terms]. 3. If, during the Term, the Supplier provides a Comparable Customer with a net effective price or other covered term more favourable than the Customer's, the Supplier shall notify the Customer within [30] days and extend the more favourable term to the Customer with effect from the date it was first offered to the Comparable Customer. 4. "Covered terms" are limited to: [price], [discounts], [payment terms], [service levels]. All other terms are excluded. 5. Once per [12] months, an independent auditor appointed by the Customer may, on reasonable notice and subject to confidentiality, review the Supplier's records solely to confirm compliance with this clause.

- **Clause 2 (comparable customer).** This is the heart of the clause. Keep it tight. A promise to match terms given to "any customer" is almost impossible for a seller to honour and administer.
- **Clause 3 (trigger and remedy).** Decide whether the better term flows automatically or only on notice, and from what date. A retrospective reduction is harder to administer than one that applies going forward.
- **Clause 4 (covered terms).** List them. An open-ended clause invites arguments about whether a free training session or an extra support tier counts.
- **Clause 5 (audit).** A most favoured customer clause with no way to verify it is close to worthless. A confidential, independent audit right is the usual answer. ## Negotiation points for the buyer - **Press for a clear, enforceable trigger and a real audit right.** Without them the clause is comfort, not protection.
- **Define covered terms broadly but precisely.** Name price, discounts and the handful of terms you actually care about.
- **Make the remedy automatic where you can.** A clause that only works if you notice and complain shifts the burden onto you. ## Negotiation points for the seller - **Narrow the comparison group hard.** Tie it to the same product, similar volume and similar commitment, so a small special deal for one customer does not reset the price for everyone.
- **Exclude one-off and strategic deals.** Carve out pilots, legacy pricing, bundled deals and launch customers.
- **Cap the administrative burden.** Limit audits to once a year, through an independent party, under strict confidentiality, and only to check this clause.
- **Watch competition law.** Wide MFN promises across many customers can attract regulatory attention. ## Common mistakes to avoid - Leaving "comparable customer" undefined, so the clause either means everything or nothing.
- Promising parity on "all terms" rather than named terms.
- No audit right, so the buyer can never actually check compliance.
- Ignoring competition law, especially for broad clauses or in regulated sectors.
- Forgetting to say whether the promise is retrospective or only forward-looking. ## A note on jurisdiction As a contract term, a most favoured customer clause is generally enforceable across common-law and civil-law markets, but the competition-law overlay varies by jurisdiction. Antitrust regulators in the United States and the European Union have scrutinised wide MFN clauses, especially in online platforms and health care, and some settings restrict or ban them. In India the clause is a contract term under the Indian Contract Act, 1872, with competition questions governed by the Competition Act, 2002. In the UK, Ireland, Singapore and Australia the competition analysis differs again. Treat "varies by jurisdiction" as the rule and confirm the competition position in each market.

It is living with it: remembering which customers you promised parity to, checking every new deal against those promises before you sign, and spotting when a discount you gave one account quietly entitles another to the same. That ongoing work is the idea behind an AI contract workspace. It can hold your contracts as linked clauses rather than scattered files, surface every most favoured customer promise you have made and show whether a clause sits favourable, neutral or unfavourable to your company, let you edit wording in plain English, and keep key terms and obligations in view as the portfolio grows. Tools such as [Adira](https://adiralaw.com) are built around that single-workspace idea, tuned to how your company contracts. The guidance above is enough to draft and negotiate the clause on its own; a workspace simply keeps drafting, review and tracking as one connected job.
