# Seeing (and Acting on) the Cost Shock Before It Hits Your Margin

When your supplier increases their prices (your costs) or a new tariff is in play, the notice arrives, purchasing loads the new cost, and the next supplier invoice is higher.

But what usually *doesn’t* happen is a change in the official margin reports that sales and pricing look at every week. Those reports or dashboards keep showing the margin the business earned *before* the increase, sometimes for months, while every order ships at the new cost.

Back in May we wrote about [how to respond to a cost shock](https://revomo.ai/blog/pricing-in-an-era-of-cost-shocks-a-practical-framework-for-margin-agility/): deciding who absorbs how much of the increase and how to bring customers along. That piece assumed you already knew the shock had arrived. In practice, knowing is often the slow part. Last week’s piece on [finding the leak before quarter-end](https://revomo.ai/blog/finding-the-leak-before-quarter-end-finds-it-for-you/) was about detection lag in discounts, rebates, and freight. A cost increase has its own detection lag, and it’s usually longer.

### The margin report is running on last year’s cost

Most margin reporting by customer and product runs on a “standard cost.” Standard cost is a useful accounting tool. It keeps inventory valuation more stable over time and makes variances easy to explain. It also tends to be updated once a year, sometimes once a quarter.

When a supplier raises a price in the middle of that cycle, the new cost shows up first in purchasing. Depending on how the company values inventory, finance sees it either as a purchase price variance at the company level or as a slow drift in average cost as older stock sells through. Neither of those changes the margin on a quote, a customer, or a SKU in the reports the commercial team uses. Until the next cost roll, those reports keep calculating margin against the old number.

Here is an illustrative example. A distributor sells $50M a year of a product family at a 25% gross margin, so about $37.5M of cost. In June, the main supplier for that family raises prices 6%. Measured on replacement cost (what it would cost to buy or make the item again today), margin on that family drops to about 20.5%, a loss of roughly $190K a month. The margin report, still on a standard cost set last January, keeps showing 25% until the next roll. By the time the January roll catches up, seven months later, around $1.3M of margin has gone out the door with nothing in the commercial reports to show it.

The report still says 25%. Today’s cost says 20.5%.

Margin on standard cost shows 25% all year until the January roll. Margin on replacement cost drops to about 20.5% in June. The gap is about $190K a month, about $1.3M by the roll.

Illustrative: a $50M product family at 25% margin, supplier up 6% in June, standard cost rolled each January. Hover or focus a month to read both lines.

The fix in the reporting is simple to describe. Alongside standard margin, carry margin on replacement cost. When the two numbers start to separate on a product family, that gap is the cost shock, visible in the same week the new cost is loaded.

### Some prices were promised before the cost moved

Seeing the gap is the first half. The second is knowing where it can be closed and where it can’t yet.

A good share of next month’s revenue is already committed at prices set before the increase. Open quotes are often valid for 30 to 90 days. Annual contracts may set prices for a year, with or without an escalation clause. Special pricing agreements and customer-specific prices sit outside the normal increase process at many companies, which is exactly why they get missed. Project and blanket orders can carry a price for months.

Each of these needs its own answer. An expiring quote can simply be reissued at the new cost. A contract with an escalation clause may allow a mid-term adjustment if someone invokes it on time. A contract without one becomes a negotiation at renewal, and it’s worth knowing the size of that negotiation before the renewal meeting. The only way to get there is to tie every committed price back to the cost it was built on, so you can list the commitments that are now below target margin and the dollars attached to each.

### Size the gap before you reprice

Before anyone sends an increase letter, the useful number is the recovery gap: the cost increase in dollars, by customer and product, over the period you expect it to last. That number gives the response a budget. It shows which customers carry most of the exposure and how much of it a given price move would actually recover, after setting aside the business that’s protected by contract for now.

It also gives you something to measure afterward. Once new prices go out, compare the price change realized on actual invoices with the cost change on the same lines. That cost recovery ratio is a far better test of the response than whether the increase letter went out on time. Increases announced at 6% often realize well below that, once exceptions, grandfathered quotes, and negotiated holds work their way through. Tracking the ratio by customer and rep shows where the recovery stalled and who needs a follow-up conversation.

### Shortening the time from cost change to price change

Most of what slows a cost response is handoffs. Purchasing loads the cost, someone in pricing eventually notices, an analyst builds the impact in a workbook, a proposal goes to sales leadership, and the change is keyed in by hand. Each step waits on the one before it, and each one can sit in someone’s inbox for a week.

This is a sensible place for automation, as long as humans keep the decision. When the landed cost file refreshes, a workflow can flag every item whose cost moved past a set threshold and route a proposed change to those prices to the person who approves it, with the margin impact attached. The workflow prepares the change, and approval still decides whether it’s published. The time saved comes from removing the waiting between steps, while the judgment about how much to pass through and to whom stays with the people accountable for it.

### Where to start tomorrow

Pick the largest supplier or freight increase your company absorbed in the last twelve months. Find three dates: when the higher cost first appeared on a supplier invoice, when it reached the cost used in your margin reports, and when your own prices changed. Then estimate the margin dollars on everything sold between the first date and the last.

That number is the cost of seeing the shock late. For most companies it’s large enough to justify carrying replacement cost in the margin view, and it gives you a baseline to beat the next time a supplier notice arrives.
