A vendor price increase is a supplier's notification that their prices are going up, usually with 30 to 60 days notice and a brief explanation. Most get absorbed without much scrutiny, because checking takes time and pushing back feels confrontational.
That absorption is expensive. A 6% increase on a line item that is 15% of your cost of goods sold moves your gross margin by nearly a point. Do that three times in a year and you have given away most of a price increase you never took. It's the mirror image of raising your own prices — the same math, just pointed at you instead of by you.
First: is it real?
Price increases come in three varieties and they warrant different responses.
Input-driven. A genuine cost pass-through — raw materials, freight, labor, tariffs. These are usually verifiable. If a vendor cites steel or resin or ocean freight, those indexes are public. An increase that matches the index movement is legitimate. One that exceeds it by double is a margin grab wearing a cost-increase costume.
Market-driven. Demand exceeds supply, so prices rise because they can. Harder to argue with, but also the most likely to reverse. Worth negotiating a review date rather than accepting it as permanent.
Testing. Some increases are simply a test of whether you are paying attention. These are identifiable by what is missing: no explanation, no notice period, no comparable increase to other customers you can check with. They are also the easiest to push back on, because there is nothing to defend.
What to check before responding
Your actual annual spend with them. Not the unit price — the total. This determines your leverage and whether the increase is worth your time. A 6% increase on $8,000 a year is $480 and probably not worth a negotiation. On $200,000 it is $12,000 and absolutely is.
Your share of their revenue. If you are a meaningful customer, you have leverage you may not be using. If you are one of four hundred accounts, you likely do not.
When they last raised prices. A vendor who has held pricing for three years asking for 8% is different from one asking for 5% every nine months. The second is a pattern worth naming out loud.
Whether the increase applies to everything. Often it is applied across the board when the underlying cost only affects part of the line. Asking for the increase to be applied only where the cost actually moved is a reasonable and frequently successful request.
What switching would cost. Not just the price difference — qualification time, tooling, minimum orders, risk. If switching is genuinely impractical, negotiate on terms rather than price, because price is where you have the least room. This is the same math that applies when a vendor is missing deadlines rather than raising prices — leverage depends on how real your alternative actually is.
What to actually ask for
Pushing back on the percentage is the least effective move. It is the one thing the vendor has already decided and defended internally.
More productive asks:
- Delay. Ninety days instead of thirty. Costs them little, saves you real money, and lets you plan.
- Phasing. Half now, half in six months.
- Scope. Apply it to the affected SKUs only, not the catalog.
- Something in exchange. Better payment terms, freight included, a volume tier, priority allocation, or a price hold through your next fiscal year in return for accepting it now.
- A commitment on frequency. No further increases for twelve months. This is often the most valuable thing you can get and the easiest for them to give — and it's worth writing directly into the contract rather than treating it as a verbal understanding that expires with whoever you talked to.
The thing most owners skip
Deciding whether you are passing it on. A price increase you absorb is a margin decision you made by not deciding. Before you respond to the vendor, know whether this cost is going into your own pricing, and if not, why not.
That conversation with yourself is worth more than the negotiation.
When you want the leverage checked before you reply
Knowing whether a 6% increase is worth fighting means knowing your actual annual spend with that vendor and what it does to your margin — not a guess, the real number.
