Supplier Price Increase Response Letter Template
Price increase notices often arrive as a single paragraph and a deadline. A short written reply that asks for cost evidence, keeps current prices in force and offers a counter keeps the negotiation on your terms.

Supplier Price Increase Response Letter Template
Acme Precision Ltd 2026-10-20
To: Ms. R. Chen, Sales Director, Northline Castings Co. Subject: Your price notice dated 2026-10-08
Response
Thank you for your notice about Aluminium housings, part family HX-200. You requested: 9 percent from 1 January 2027.
Our position: Not accepted as submitted.
Information we need
To evaluate the request we ask for the following:
A breakdown of material, labor, energy and overhead in the current price, the index you are using and the quantity of material per part.
Our proposal
A 3 percent increase tied to the published aluminium index, effective 1 March 2027, with the price held for 12 months.
Next steps
Current prices remain in force under the existing agreement until a revised price is agreed in writing. We would like to meet within two weeks to review the data together. We value the relationship and want a result that is fair to both sides.
Check your supply agreement for notice periods and price adjustment clauses before sending. This is a starting point, not legal advice.

Optional: a read-only check comparing invoice and PO prices to the price list.
Optional. The tool and every export work without this. No spam.
How to use the letter
Choose your position first, then fill in the counter and the information you need. Keep the tone neutral. The goal is to move the discussion from a percentage to a cost model. Send it to the person who issued the notice and copy your own category manager. Export to PDF or Word and keep the sent copy with the supplier file.
- Confirm the date and effective date in their notice.
- Ask for a cost breakdown, not just a reason.
- State that current prices stay in force until agreed in writing.
What strong counters look like
Tie increases to a public index with a formula, such as the material share of the price multiplied by the index change. Offer a longer price hold, volume commitment or shorter payment terms in exchange for a smaller increase. Phased dates give both sides time to adjust. Use the price increase impact calculator on this site to size the gap between the requested and the justified amount.
ERP notes
Do not update the ERP price until the revised price is agreed. Then end-date the old price record and enter the new one with its effective date, using your ERP's purchasing price list or info record. Watch open purchase orders: some systems reprice open lines on a price change, which can surprise you.
Common mistakes
Ignoring the notice and hoping it goes away, accepting a rise because a deadline looks firm, arguing about percentages without data, and agreeing verbally. Another mistake is reacting to a single supplier while the whole commodity moved: check the index first so you know how much of the request is real.
Frequently Asked Questions
Can a supplier raise prices mid-contract?
Only as the agreement allows. Look for a price adjustment, index or force majeure clause. Without one, the contract price holds until it expires, though a supplier may request a change and you may choose to negotiate.
Should I always ask for a cost breakdown?
Yes for significant increases. A breakdown into material, labor, energy, overhead and margin shows what actually changed and lets you test each element against an index.
What if the supplier threatens to stop shipping?
Check the agreement for supply obligations and consider your alternate sources. Keep the tone calm, escalate to a senior contact and avoid agreeing under time pressure without data.
Is this letter legally binding?
It is a business letter, not a contract amendment. Any agreed new price should be confirmed in a signed amendment or an updated purchase order terms document.
If you want price changes detected automatically from invoice and PO history in your ERP, Netray can build a read-only monitor that flags unannounced increases.
