Contracts & negotiation

A supply contract is a way of deciding who carries which risk. Price matters, but the terms around it, such as volumes, flexibility, penalties and how prices move, often matter more.

How price is set:

• Fixed price: stable and easy to budget; the supplier carries cost risk and prices that in.
• Cost-plus: the buyer pays cost plus a margin. Useful when costs are hard to predict, but it gives the supplier little reason to cut cost.
• Index-linked: price moves with a published index, such as steel, resin or diesel. Neither side gambles on the market.

How volume and flexibility are shared:

• Volume commitment or take-or-pay: the buyer promises a minimum and pays for it even if it buys less. The supplier invests with confidence and gives a better price.
• Quantity flexibility: the buyer can adjust orders within a band, say ±20%, as demand becomes clearer.
• Buyback and revenue sharing: the supplier takes back unsold stock or shares retail revenue, which encourages the retailer to stock more, as in publishing and film rental.

Service terms: lead times, OTIF targets, quality levels, and penalties or rewards (service level agreements).

In negotiation, know your BATNA (best alternative to a negotiated agreement): what you’ll do if there’s no deal. Trade across several terms instead of fighting over price alone, for example a longer commitment for a lower price, or faster payment for a discount.

Index-linked pricing

Split the price into the part that follows a cost index and the part that doesn’t:

where $a$ is the share of cost tied to the index $I$, such as a resin price index.

Good index clauses name the exact index, the reference period, how often the price resets and what happens if the index stops being published.

Flexibility and commitment

• Quantity flexibility: with a monthly forecast of 10,000 and ±20% flexibility, the buyer may order between 8,000 and 12,000 a month, and the supplier plans capacity for 12,000.
• Take-or-pay: a commitment of 1 lakh units a year means paying for any shortfall, at full or reduced price, if the buyer takes only 85,000.
• Lead-time commitments: orders within the frozen period can’t be changed; beyond it, changes are free within limits.

Each gives one side security and the other side flexibility, so each should be priced.

Aligning incentives with buyback

A retailer sells at ₹100, buys at ₹60 and can’t sell leftovers. Its critical ratio is $(100 - 60)/(100 - 0)$ = 0.40, so it stocks low. For the chain as a whole, with a production cost of ₹20, the ratio is $(100 - 20)/100$ = 0.80.

Negotiating

Know your BATNA, the best alternative if there is no deal (another supplier’s TCO, making in-house), and estimate the other side’s. The range between the two walk-away points is the zone of possible agreement. Trade across terms: a longer commitment for a lower price, faster payment for a discount, more flexibility for a higher price.

Paying for outcomes

• Performance-based contracts pay for results instead of activities: aircraft engines paid per flying hour, so the maker earns more when engines run reliably and spends less on spare parts.
• Gain-sharing: savings from supplier ideas are split, so the supplier has a reason to suggest them.
• Service levels with incentives and penalties: OTIF, response times and quality with rewards as well as penalties.

Relational contracts

For complex, long-term relationships, detailed contracts can’t foresee everything. Relational or “vested” approaches set shared goals, joint governance and fair ways to share gains and pains, alongside the legal terms. They suit strategic partnerships; transactional contracts suit leverage purchases.

Clauses that matter in a crisis

The pandemic taught many companies to read the fine print:

• Force majeure: what counts, notice requirements, and what happens to obligations.
• Allocation: how a supplier shares scarce output among customers.
• Price adjustment: how and when prices can change if costs jump.
• Termination and transition: how to exit without losing supply, tooling or data.
• Intellectual property and tooling ownership, so you can move production if needed.

The Indian legal frame

In India, commercial contracts are governed by the Indian Contract Act, 1872, and disputes are often resolved through arbitration under the Arbitration and Conciliation Act, 1996. Procurement teams work with legal on standard terms, but should understand the commercial logic of each clause they negotiate.

Winning too hard

A negotiation that pushes a supplier below sustainable margins looks like a win until the supplier cuts quality, stops investing, deprioritizes your orders in a shortage, or fails. The best contracts leave both sides better off than their alternatives, which is also what keeps them in force when conditions change.
