Getting a product into Costco requires more than completing a generic vendor application. Suppliers must demonstrate that their product delivers exceptional value to Costco members, can generate strong sales with a limited number of SKUs, and can be produced and distributed reliably at scale.
Costco’s public vendor information does not describe one universal approval process for every product. The correct contact and requirements can vary by product category, region, sales channel, and supplier type. This guide explains how to prepare your product, approach the appropriate Costco office, build a buyer-ready proposal, and get your operations ready if Costco expresses interest.
Quick answer: To get your product into Costco, first confirm that it fits Costco’s value-focused warehouse model. Prepare your wholesale pricing, packaging, sales data, production capacity, compliance documents, and logistics plan. Food and sundry suppliers should then contact the appropriate Costco regional office, while suppliers in other categories can contact Costco’s corporate office. Approval is not guaranteed and additional reviews may be required.
How Do You Get a Product Into Costco?
The process normally begins before you contact Costco. A supplier must first determine whether the product offers the combination of quality, value, differentiation, and operational reliability expected by a high-volume warehouse retailer.
Costco does not publish a single application workflow that applies to every supplier. However, prospective vendors can follow the seven-step framework below to prepare a credible proposal and reach the appropriate Costco buying organization.
| Step | What to Do | Desired Outcome |
|---|---|---|
| 1 | Evaluate your product’s fit with Costco | Confirm that the item offers quality, value, and broad member appeal |
| 2 | Build a Costco-ready offer | Establish packaging, pricing, and margins suitable for volume retail |
| 3 | Prove demand and capacity | Show sales velocity, production capacity, and inventory readiness |
| 4 | Prepare compliance documents | Organize insurance, certifications, testing, and supplier policies |
| 5 | Contact the correct Costco office | Reach the corporate or regional buying organization |
| 6 | Present a buyer-ready pitch | Give the buyer a concise, data-supported commercial proposal |
| 7 | Prepare for onboarding and fulfillment | Be ready for item setup, orders, logistics, and ongoing performance |
Step 1: Determine Whether Your Product Is a Good Fit for Costco
Costco operates a high-volume retail model based on offering members low prices on a deliberately limited product selection. As a result, a product must do more than fill a category. It should give Costco members a clear reason to choose it over an existing item.
Evaluate whether your product offers a distinctive benefit, a compelling price-to-value relationship and enough consumer appeal to generate strong sales from limited shelf space. Products may compete through quality, size, formulation, exclusivity, convenience, sustainability, innovation or a Costco-specific configuration.
Evaluate the Value Offered to Costco Members
Buyers need to understand why the product represents a better value for Costco members. This does not necessarily mean offering the lowest unit price. The value may come from a larger package, premium formulation, exclusive bundle, longer useful life or stronger performance at an attractive cost per unit.
State the member benefit numerically whenever possible. For example, compare cost per ounce, cost per serving, number of uses, product life or savings versus comparable retail formats.
Research the Existing Costco Assortment
Visit Costco warehouses in the regions you want to target and review Costco.com to identify comparable products, package sizes, prices and promotional patterns. Record what your product adds to the category instead of simply stating that it is “better.”
Because assortment can vary by warehouse and region, observations from one location should not be treated as proof of Costco’s entire national assortment.
Decide Whether You Are Ready for Regional or Broader Distribution
A regional launch can be more realistic for an emerging brand with concentrated demand or limited production. A supplier pursuing broader distribution must demonstrate substantially greater manufacturing, inventory and logistics capacity.
Your proposal should define the geographic area you can serve reliably rather than promising national coverage that your operations cannot support.
Step 2: Create a Costco-Ready Product, Package and Price
Your standard retail configuration may not be the best format for Costco. Warehouse clubs frequently depend on larger sizes, multipacks, bundles or exclusive configurations that create visible value while maintaining a sustainable economic model for both parties.
Develop a proposal that accounts for manufacturing, packaging, freight, warehousing, promotions, potential allowances and your required margin. Do not base your offer only on the price charged to smaller retailers.
Design a Warehouse-Club Package
Packaging should communicate the product and its value quickly, remain stable during transportation and storage, and work efficiently on pallets or retail displays. Consider case dimensions, pallet configuration, product protection, labeling, barcode placement and shelf-ready presentation.
Food, beverage, health and regulated products may require additional labeling, traceability, expiration-date or temperature-control planning.
Build a Sustainable Wholesale Price
Calculate the complete delivered cost before presenting a price. Include production, primary and secondary packaging, inbound materials, freight, storage, order preparation, returns, deductions, promotions and compliance-related expenses.
Costco does not publicly provide a universal supplier margin formula. Avoid using an alleged “Costco markup requirement” unless the number comes directly from the buyer or your agreement.
Consider an Exclusive Costco Configuration
A unique pack size or bundle can make direct price comparisons more difficult and give members a differentiated reason to buy. However, exclusivity should not create unnecessary packaging complexity or undermine your other retail channels.
Model the operational and financial impact before promising an exclusive format.
Step 3: Prove Consumer Demand and Production Capacity
A compelling product story is stronger when supported by evidence. Prepare sales performance, customer retention, reorder rates, retail velocity, geographic demand, reviews, distribution growth and relevant category research.
Costco must also be confident that demand will not exceed your ability to supply. Document current capacity, maximum sustainable output, production lead times, backup suppliers, safety stock and plans for unexpected demand.
Sales Evidence to Include in Your Proposal
Use recent, verifiable data and explain the period, stores and channels represented. Avoid presenting total revenue without showing whether the product sells consistently at the individual store or account level.
| Evidence | What the Buyer Should Learn |
|---|---|
| Unit sales and revenue | Current commercial scale |
| Sales per store per week | Product velocity |
| Reorder rate | Repeat demand |
| Customer retention | Whether purchases continue over time |
| Distribution growth | Ability to expand successfully |
| Online ratings and reviews | Customer response and recurring concerns |
| Regional sales concentration | Best areas for an initial launch |
| Inventory fill rate | Reliability of product availability |
Operational Metrics to Prepare
Step 4: Organize Your Compliance and Supplier Documentation
The exact documents required will depend on the product and the proposed relationship. Preparing them early prevents compliance questions from delaying a promising commercial opportunity.
Costco expects suppliers to meet its standards for quality, value and service and to comply with its Supplier Code of Conduct. Costco states that suppliers must respect the human rights and safety of people throughout the supply chain.
Create a Vendor Document Checklist
Present operational figures that can be verified internally. Buyers may ask additional questions depending on the category, but you should know your monthly capacity, lead time, case pack, pallet configuration, shelf life, minimum production run and order fill rate before the first serious conversation.
| Document or Information | When It May Be Relevant |
|---|---|
| Company and tax information | General vendor onboarding |
| Product liability insurance | Physical consumer products |
| Product specifications | Quality review and item setup |
| UPC or GTIN information | Product identification |
| Packaging and case dimensions | Warehousing and logistics |
| Safety or laboratory test results | Food, health, beauty, or regulated products |
| Manufacturing certifications | Category- or facility-specific requirements |
| Ingredient and allergen information | Food and beverage products |
| Shelf-life documentation | Perishable or date-sensitive products |
| Recall and traceability plan | Food and regulated products |
| Supplier Code of Conduct compliance | Supply-chain and labor standards |
| Production and facility information | Capacity or compliance evaluation |
This is a preparation checklist, not a definitive list of documents required from every Costco supplier. Confirm the final requirements directly with Costco during review and onboarding.
Step 5: Contact the Correct Costco Buying Office
Costco’s official vendor page separates prospective suppliers by product type. Suppliers of food and sundry items are directed to the appropriate regional or division office. Prospective vendors of other products are directed to Costco’s corporate office.
Do not describe this contact page as a universal online vendor application. It provides the official contact route, but the subsequent evaluation process can depend on the category and buying team.
Where Food and Sundry Suppliers Should Start
Present operational figures that can be verified internally. Buyers may ask additional questions depending on the category, but Choose the regional office that corresponds to the market where you can realistically launch and fulfill orders. Costco currently publishes contact information for the Northwest, Northern California, Los Angeles, San Diego, Texas, Midwest, Northeast and Southeast regions.
Because addresses and phone numbers can change, link directly to Costco’s official Vendor Inquiries page rather than reproducing the entire directory in the article.should know your monthly capacity, lead time, case pack, pallet configuration, shelf life, minimum production run and order fill rate before the first serious conversation.

Where Non-Food Suppliers Should Start
Costco instructs prospective vendors of non-food or non-sundry items to contact its corporate office. Include a concise introduction to your company and request guidance to the appropriate merchandise category or buying team.
Your first communication should identify the product, category, target market, key consumer benefit and evidence of demand. Avoid sending large unsolicited files until the recipient confirms the preferred submission method.
When to Use Costco’s Supplier Inclusion Form
Qualified U.S.-owned small and diverse suppliers may also review Costco’s Supplier Inclusion Program. This is a specific program with eligibility requirements and should not be presented as Costco’s general vendor application.
Costco states that completing its Supplier Inclusion intake form does not guarantee a business partnership. Costco Supplier Inclusion.
Step 6: Prepare a Product Pitch for a Costco Buyer
A buyer pitch should make the commercial opportunity easy to evaluate. Lead with the member value and sales evidence rather than the company’s complete history. The buyer should quickly understand what the product is, why Costco members would buy it, how it differs from the current assortment and whether your company can supply it reliably.
Prepare a short presentation and a detailed supporting file. The short version should work as an initial introduction, while the supporting material should contain financial, operational and compliance details.
What to Include in Your Costco Product Pitch
| Pitch Element | Question It Should Answer |
|---|---|
| Product overview | What exactly are you selling? |
| Member value proposition | Why is it a strong value for Costco members? |
| Differentiation | What does it add to the current category? |
| Sales performance | What evidence proves demand? |
| Proposed configuration | What size, pack, or bundle will Costco receive? |
| Wholesale economics | What is the proposed delivered cost? |
| Production capacity | Can you fulfill high-volume orders consistently? |
| Geographic coverage | Which regions can you serve? |
| Marketing support | How will you help create awareness and demand? |
| Compliance readiness | Are the required documents and controls available? |
Costco Vendor Pitch Example
“[Product name] is a [product category] designed for [target consumer]. It gives Costco members [specific benefit] through a [pack size or exclusive configuration] at an estimated cost of [amount] per unit or use. The product currently generates [verified sales metric] across [number or type of accounts], with a [reorder rate or growth metric]. We can currently produce [capacity] per month and serve [regions] with a lead time of [number] days.”
Step 7: Prepare for Costco Vendor Onboarding and Fulfillment
Buyer interest is not the end of the process. A supplier may still need to complete item setup, provide documentation, agree to commercial terms and demonstrate that orders can be processed and fulfilled accurately.
Requirements may include specific data formats, product identifiers, logistics labels, purchase-order workflows, routing instructions, invoices or electronic transactions. Do not claim that EDI is mandatory for every prospective supplier; confirm the actual technical requirements during onboarding.
Build a Retail Fulfillment Plan
Define who will receive purchase orders, reserve inventory, prepare shipments, produce labels, schedule transportation, send invoices and resolve deductions or discrepancies. Assign ownership before the first order arrives.
Create escalation procedures for shortages, late production, rejected shipments, damaged cases and data errors.
Track Product Performance After Launch
If your product launches, monitor units shipped, order fill rate, on-time delivery, inventory availability, returns, deductions and sales performance. A successful retail relationship depends on both consumer demand and operational execution.
Use performance data to identify whether production, inventory or distribution must be adjusted before expanding to additional warehouses or regions.

Final Thoughts: Build a Costco-Ready Business, Not Just a Pitch
Getting your product into Costco begins with a strong product-market fit, but long-term success requires pricing discipline, reliable production, accurate inventory and consistent fulfillment. A polished presentation cannot compensate for an offer that lacks member value or a supply chain that cannot support retail volume.
Start by evaluating your product honestly, building a Costco-specific commercial proposal and contacting the correct office through Costco’s official vendor resources. If interest develops, verify every operational and technical requirement directly with the buyer or onboarding team before making investments or commitments.
