Contract management: getting the commodity terms right before you sign
A supplier contract is where margin drift gets locked in for years. Set the baseline price too high or write the indexation clause too loosely, and you will overpay on every PO until renewal, usually without noticing. The cheapest time to fix a bad price is before the ink dries.
The problem
New contracts are often baselined on the incumbent price plus a negotiated adjustment. If the incumbent price already contained unverified drift, the new contract inherits it and compounds it. Worse, price-adjustment clauses are frequently written to track a published index in a way that lets the supplier pass through the full commodity move on the full part price, even though material is only a fraction of that price.
These terms are hard to challenge at signing because the buyer rarely has an independent cost model in the room. The supplier's draft becomes the default, and the asymmetry of information that hurts in negotiation hurts even more in the document that governs the next three years of spend.
How Agent Midas helps
Before signing, Agent Midas gives you an independent should-cost to baseline the contract against, so you start from a fair price rather than an inherited one. It shows the true material share of landed cost, which is the number that should govern any indexation clause, the increase should apply to the material portion, not the whole part.
Midas can model how a proposed price-adjustment clause would behave under different commodity scenarios, so you can see, before you agree, how much a loosely-worded clause would cost you over the life of the contract. That turns contract language from boilerplate into a negotiated, quantified term.
Worked example
A manufacturer is renewing a three-year casting contract worth $1.2M a year. The supplier's draft indexes price to the aluminium benchmark, passing through 100% of any move on the full part price, reviewed quarterly.
Agent Midas models the clause: material is about 38% of the casting's landed cost, so a full-part pass-through over-compensates the supplier by roughly 2.6× on every commodity rise. Across a plausible three-year price path, that drafting alone would cost an estimated $90,000–$140,000 versus a clause indexed to the material share.
The buyer counters with a clause that applies the index to the material portion only, with a documented should-cost baseline attached as an annex. The supplier agrees, the logic is hard to argue with, and the contract is signed on terms that track real cost rather than amplifying it.
