Pricing a product when your costs keep changing means building a price that protects your margin as inputs move, instead of picking one number and hoping costs hold still. Most owners do the opposite: they set a price once, watch material or freight costs creep up over six months, and only notice the damage when they pull a P&L and the margin line looks wrong. By then you've sold hundreds of units at a price that was only profitable in January.
Why a fixed price is the trap
A price list feels like stability. It's actually a bet — a bet that your costs won't move enough to matter before you revisit it. For a lot of small manufacturers, distributors, and food and beverage operators, that bet loses. Steel, resin, packaging, freight, labor — any of these can move 8-15% in a quarter without anyone deciding it should. If your price doesn't move with them, your margin absorbs the entire difference, silently, one invoice at a time.
The fix isn't repricing constantly — that confuses customers and looks chaotic. The fix is separating your price into two parts: a base price you set deliberately, and a mechanism that adjusts for cost movement without you having to renegotiate the whole relationship every time a supplier raises rates.
Three ways to build in flexibility
1. Index your price to a real cost driver. If a material makes up a large share of your cost, tie your price to a published index for it — a steel index, a resin index, a fuel surcharge table. Put the mechanism in the contract or quote itself: "price adjusts quarterly based on [index], capped at X% per adjustment." Customers who buy from volatile-input industries already expect this. You're not asking for anything unusual — you're just formalizing what's already true.
2. Set a review cadence, not a reaction threshold. Waiting until margin erosion is obvious means you're always reacting late. Instead, put a specific date on the calendar — every 90 days, review landed cost against current price for your top 20 SKUs by volume. This catches slow drift before it becomes a real problem, and it's a much easier conversation with a customer when it's "our quarterly review" instead of "we're raising prices because we're losing money."
3. Separate volatile and stable costs in your pricing model. Not every input moves the same way. Labor and overhead are relatively stable; certain raw materials or freight lanes are not. If you price everything as one blended number, a spike in the volatile piece gets buried and you can't tell which part of your margin is actually at risk. Break your cost stack into stable and volatile components, and only the volatile piece needs the adjustment mechanism — this also makes the conversation with customers narrower and easier to justify.
What this looks like with a real customer
Say you sell a component where raw material is 40% of landed cost and it's been rising steadily. Instead of holding your price and eating the increase, or raising it all at once and surprising the customer, you'd quote a base price plus a documented adjustment tied to a public material index, reviewed quarterly, with a cap so neither side gets blindsided. The customer can see exactly why the number moves. You're not guessing at a new price every time costs shift — you're running a formula you already agreed on.
The number that actually matters
None of this works if you don't know your real landed cost per unit right now, including freight and any recent supplier increases — not what it cost six months ago, not what's on the original quote you built your price from. That's the actual first step, before indexing or review cadences: pull your current cost, compare it to your current price, and see how much room you actually have. A lot of owners are surprised to find the gap is bigger than they thought.
This is exactly the kind of question that's easy to keep putting off because it takes an hour of pulling numbers you don't have time for. It's also the kind of question Helm's CFO advisor is built to help with directly — connect QuickBooks, ask it to check your current margin against your last price update, and get a straight answer instead of a spreadsheet you have to build yourself.
