Price changes can feel awkward to announce. A supplier wants to protect profit margins, while every customer hopes costs will stay the same. Somewhere between those two goals sits a letter that can either strengthen a business relationship or create unnecessary tension.
A rushed message often raises more questions than it answers. Customers may wonder why prices are changing, when the new rates begin, or whether they have any options before the increase takes effect. A clear letter removes that uncertainty before it turns into frustration.
The good news is that a price increase notice does not have to sound cold or defensive. A thoughtful message can explain the situation honestly, give enough notice, and show customers that their business still matters.
Sample Letters of Supplier Price Increase Notice
Every business has a different reason for adjusting prices. The samples below cover several common situations, giving you ready-to-use letters that fit different industries, customer relationships, and levels of formality.
1. General Supplier Price Increase Notice
Subject: Upcoming Price Adjustment Effective August 15, 2026
Dear Ms. Thompson,
Thank you for your continued partnership with Horizon Packaging Supplies over the past four years. Your business has been greatly appreciated, and we remain committed to providing dependable products and consistent service.
This letter is to inform you that the prices of our packaging materials will increase by an average of 6%, effective August 15, 2026.
Over the past several months, the cost of raw materials, transportation, and manufacturing has risen steadily. Although every effort has been made to absorb these increases internally, maintaining our current pricing is no longer sustainable while continuing to provide the quality and service you expect.
Any orders received before August 15, 2026 will be processed at the current prices. Orders placed on or after that date will reflect the updated pricing schedule.
An updated price list is attached for your reference. If you would like to discuss your current purchasing agreement or upcoming orders, please contact your account representative at any time.
Thank you for your understanding and continued trust. We look forward to serving your business for many years to come.
Sincerely,
Daniel Brooks
Sales Manager
Horizon Packaging Supplies
2. Price Increase Due to Rising Material Costs
Subject: Notice of Raw Material Price Adjustment
Dear Mr. Patel,
Thank you for choosing Sterling Metal Components as one of your trusted suppliers.
This letter serves as formal notice that, beginning September 1, 2026, prices for our stainless steel products will increase by 8%.
Global increases in steel prices and higher production costs have significantly affected manufacturing expenses over recent months. Every reasonable measure has been taken to manage these costs without affecting customers. Unfortunately, the continued rise in material prices now requires an adjustment.
Orders confirmed before September 1 will be honored using our existing pricing schedule, provided delivery dates fall within the agreed production timeline.
A revised catalog and pricing sheet have been enclosed for your review.
We sincerely appreciate your continued confidence in our products and hope to continue supporting your business with reliable quality and dependable delivery.
Please feel free to reach out if you have any questions regarding existing quotations or future orders.
Kind regards,
Melissa Grant
Commercial Director
Sterling Metal Components
3. Price Increase with Advance Notice
Subject: Advance Notice of Product Price Adjustment Effective October 1, 2026
Dear Mr. Hernandez,
Thank you for your continued business with Green Valley Food Distributors. Your partnership has played an important part in our growth, and we appreciate the confidence you place in our products.
This letter is to provide 60 days’ advance notice of a pricing adjustment that will take effect on October 1, 2026.
Beginning on that date, prices across most of our product range will increase by approximately 5%. This adjustment reflects continued increases in ingredient costs, packaging expenses, fuel charges, and warehouse operating costs.
Providing advance notice gives your team time to review inventory requirements and place any planned orders before the new prices become effective. All purchase orders received by September 30, 2026, will be billed using our current pricing, provided shipment schedules remain within normal fulfillment timelines.
A complete price list has been attached for your convenience. Your account manager would be happy to answer questions or discuss volume purchasing opportunities that may help reduce future costs.
Thank you once again for your continued partnership. We value your business and look forward to supporting your company for many years ahead.
Sincerely,
Rebecca Collins
Customer Relations Manager
Green Valley Food Distributors
4. Temporary Supplier Price Increase Notice
Subject: Temporary Price Adjustment Notice
Dear Ms. Brooks,
Thank you for your continued support of Apex Industrial Chemicals.
This letter is to notify you of a temporary adjustment to our pricing, effective August 10, 2026.
Several unexpected market conditions, including short-term shortages of key raw materials and higher shipping expenses, have increased our operating costs. As a result, prices on selected products will increase by approximately 7% until market conditions stabilize.
Unlike a permanent pricing revision, this adjustment is intended to be temporary. We will continue monitoring supplier costs closely and will review pricing on a regular basis. Should production costs return to more stable levels, we fully intend to revise prices accordingly.
Orders submitted before August 10 will continue to receive current pricing.
An updated pricing schedule is enclosed for your review. If your upcoming projects require large quantities, our sales team would be pleased to discuss ordering options before the adjustment takes effect.
Thank you for your patience and understanding during this period. We truly value your partnership and appreciate your continued confidence in our company.
Kind regards,
Samuel Turner
Operations Manager
Apex Industrial Chemicals
5. Fuel and Transportation Cost Price Increase
Subject: Transportation Cost Price Update
Dear Ms. Walker,
Thank you for choosing BlueLine Distribution Services as your preferred supplier.
This letter serves as notice that effective September 15, 2026, prices for delivered products will increase by approximately 4%.
Over the past year, transportation expenses have continued to rise because of higher fuel prices, freight charges, vehicle maintenance costs, and delivery-related operating expenses. Although we have absorbed much of these increases internally, doing so is no longer practical while maintaining the dependable delivery service you expect.
Products collected directly from our warehouse will remain subject to standard pricing where applicable, while delivered orders will reflect the revised transportation costs.
Orders placed before September 15 will continue to receive current pricing.
Please review the attached pricing guide for complete details. If you have recurring deliveries or long-term supply agreements, we would welcome the opportunity to discuss options that best suit your purchasing needs.
Thank you for your continued business and understanding.
Sincerely,
Michael Dawson
Distribution Manager
BlueLine Distribution Services
6. Annual Price Review Notice
Subject: Annual Pricing Review Notification
Dear Mr. Chen,
As another successful year together comes to a close, everyone at Summit Office Products would like to thank you for your continued loyalty and support.
As part of our annual pricing review, updated product prices will take effect on January 1, 2027.
Following a careful review of supplier costs, labor expenses, warehousing, and product sourcing, prices across selected product categories will increase by an average of 3.5%.
Conducting this review once each year allows us to maintain steady pricing throughout the rest of the year while continuing to invest in product quality, inventory availability, and customer service.
Current prices will remain valid through December 31, 2026. Any confirmed orders received before that date will be processed under the existing pricing schedule.
An updated catalog is enclosed for your records.
Thank you once again for your continued partnership. We sincerely appreciate the opportunity to support your business and look forward to another successful year together.
Warm regards,
Angela Morris
Sales Director
Summit Office Products
7. Contract Renewal Price Increase Notice
Subject: Pricing Update Upon Contract Renewal
Dear Mr. Anderson,
Thank you for partnering with Premier Industrial Supplies throughout the past contract term. It has been a pleasure supporting your purchasing needs, and we appreciate the confidence you have shown in our company.
As your current supply agreement approaches its renewal date, we would like to inform you of an adjustment to our pricing that will take effect with the new contract beginning November 1, 2026.
During the past year, operating expenses have increased across several areas, including manufacturing, labor, packaging, and logistics. While every effort has been made to keep pricing stable during the existing agreement, these higher costs now require a modest adjustment. Under the renewed contract, product prices will increase by 5%.
All terms and conditions of our current agreement will remain unchanged unless otherwise discussed and approved by both parties. The revised pricing schedule is enclosed for your review, along with a copy of the proposed renewal agreement.
Should you wish to discuss purchasing volumes, contract duration, or any part of the renewal, your account manager would be pleased to arrange a meeting at your convenience.
Thank you for your continued trust and partnership. We look forward to another successful contract period together.
Sincerely,
Laura Bennett
Key Account Manager
Premier Industrial Supplies
8. Price Increase with Discount Opportunity
Subject: Upcoming Price Adjustment and Early Order Savings
Dear Ms. Foster,
Thank you for your continued business with Evergreen Wholesale Traders. Your loyalty means a great deal to us, and we are grateful for the opportunity to serve your company.
This letter is to notify you that our product prices will increase by approximately 6%, effective September 20, 2026.
The adjustment reflects ongoing increases in supplier pricing, freight charges, and operating expenses. Although these factors have steadily affected our costs, we have delayed making changes for as long as reasonably possible.
To help our customers prepare, any orders placed before September 20, 2026, will receive current pricing. In addition, customers placing orders of $5,000 or more before the effective date will receive a 2% early purchase discount.
A revised price list has been enclosed for your review.
We hope this advance notice allows your team to plan future purchases while taking advantage of existing prices. Please contact us if you would like assistance estimating inventory requirements before the adjustment begins.
Thank you for your understanding and continued partnership.
Kind regards,
David Mitchell
Regional Sales Manager
Evergreen Wholesale Traders
9. Industry-Wide Cost Increase Notice
Subject: Industry Pricing Adjustment Notification
Dear Ms. Lawson,
Thank you for your continued partnership with Northern Commercial Equipment.
This letter is to advise you of a pricing adjustment that will become effective on October 15, 2026.
Across our industry, manufacturers have experienced sustained increases in raw material prices, shipping costs, utility expenses, and production overhead. These conditions have affected suppliers throughout the market rather than a single company. As a result, prices across our product range will increase by approximately 7%.
Every effort has been made to reduce the effect of these rising costs through improved efficiency and careful expense management. Even with those measures in place, maintaining existing prices is no longer practical.
Orders confirmed before October 15 will continue to receive current pricing under normal delivery schedules.
An updated price catalog accompanies this notice. If you have open quotations or projects currently under discussion, please contact your sales representative so those opportunities can be reviewed before the adjustment takes effect.
Thank you for your continued confidence in our products and services. We sincerely appreciate your business.
Respectfully,
Natalie Rogers
Commercial Sales Director
Northern Commercial Equipment
10. Personalized Price Increase Letter for a Long-Term Customer
Subject: Important Pricing Update for Valued Customers
Dear Mr. Carter,
For more than eight years, your company has been one of our most valued customers. Everyone at Precision Print Solutions sincerely appreciates the trust you have placed in us, and we never take that relationship for granted.
Because of that long-standing partnership, we wanted to personally inform you of an upcoming pricing adjustment before it becomes effective.
Beginning December 1, 2026, prices for our printing products and related services will increase by 4%.
This decision was made only after carefully reviewing continued increases in paper costs, production materials, equipment maintenance, and employee wages. Throughout the past year, we have worked hard to absorb these higher expenses without affecting our customers. Unfortunately, maintaining current pricing is no longer sustainable while continuing to provide the same quality and turnaround times you have come to expect.
Orders placed before December 1 will continue to receive current pricing, and any quotations already accepted before that date will be honored according to their agreed terms.
If your business expects significant printing requirements over the coming months, we would be happy to discuss scheduling production before the adjustment begins. We are also available to review your account and suggest purchasing options that may help manage future costs.
Thank you once again for your continued loyalty and confidence. We truly value the relationship we have built over the years and look forward to serving your business well into the future.
Warm regards,
James Whitaker
Managing Director
Precision Print Solutions
Wrapping Up
A supplier price increase notice works best when it is clear, respectful, and timely. Customers are far more likely to accept an adjustment when they understand why it is happening, know exactly when it takes effect, and have enough time to plan ahead. A professional letter also shows that the relationship matters beyond the next purchase order.
Before sending any notice, read it once from the customer’s point of view. Does it answer the questions they are most likely to ask? If it does, there is a good chance the conversation that follows will be much smoother.
