A Costco Business membership is designed for people who run small businesses, farms, or nonprofits and want to buy in bulk at lower per-unit prices

Unlike a regular Costco membership, a Business membership lets you buy larger quantities of products without a membership cap on how much you can purchase. You can shop at any Costco warehouse, but you also get access to Costco Business centers in some locations—separate buildings that stock items regular members don't see, like restaurant supplies, janitorial products, and office equipment in bigger quantities.

The membership costs more than a Gold Star (regular) membership, but the lower unit prices and bulk quantities often offset that cost if you're buying for a business. You can add household members to your account, though only the primary member and one household card holder can make purchases.

Key Takeaways

  • A Business membership removes purchase limits and lets you buy larger quantities than regular members, with separate Costco Business centers in select cities offering items regular warehouses don't stock.
  • The annual membership fee is higher than a Gold Star membership, but the per-unit prices on bulk items are often lower than what you'd pay elsewhere.
  • You can use your membership at any Costco warehouse and at Costco.com, and you can add one household card holder to your account.
  • Business membership is open to anyone with a business license, farm permit, or nonprofit documentation—you don't need to be a large corporation.

Who can get a Business membership

You need to show proof that you operate a business, farm, or nonprofit. Costco accepts a current business license, farm permit, nonprofit documentation, or a reseller permit. Sole proprietors, partnerships, corporations, and nonprofits all may have access to. You don't need to be a large operation—a freelancer with a business license or someone running a small farm can open an account.

If you don't have formal business documentation yet, you may be able to use other proof like a business tax ID or a letter from your accountant. Policies vary slightly by location, so it's worth asking at your local warehouse what documents they accept.

What the membership includes

Your Business membership gives you access to all regular Costco warehouses and Costco.com. You can buy in any quantity without hitting a purchase cap—unlike regular members, who may face limits on certain items during high-demand periods. You also get a second household card to give to a family member or trusted employee, though only you and that one cardholder can make purchases on the account.

In cities where Costco operates a Business center, you can shop there too. These locations stock items regular warehouses don't carry: commercial kitchen equipment, bulk janitorial supplies, office furniture, and restaurant-grade food items. Not all areas have a Business center, so check Costco's website to see if one is near you.

You receive the same member discounts on gas, pharmacy services, and optical services as regular members. You can also use Costco Travel to book vacations and rental cars at member rates.

How the pricing works

Business membership pricing is typically lower per unit than regular member pricing on the same items. For example, a case of 24 cans of tomato sauce might cost less per can when you buy it through your Business membership than a regular member would pay for a smaller quantity. The savings add up quickly if you're buying regularly for a business.

However, not every item is cheaper on a Business membership—some products are priced the same across both membership types. The real advantage comes when you need to buy in bulk. If you're buying 10 cases of something instead of 2, the per-unit savings become significant.

Costco also runs occasional Business member-only deals and promotions, sent through email or posted in the warehouse. These are separate from the regular member promotions.

Costco Business centers versus regular warehouses

A Costco Business center is a separate building from a regular warehouse, and it stocks different items. While you can buy groceries, office supplies, and household goods at either location, Business centers focus on bulk quantities and commercial-grade products. You'll find larger packs of cleaning supplies, industrial equipment, commercial kitchen tools, and restaurant-ready food items.

Business centers are located in select cities only—they're not available everywhere. If you live in or near a major metropolitan area, you're more likely to have one nearby. You can search Costco's website to find Business centers in your region. If there's no Business center near you, your regular warehouse membership still gives you access to bulk pricing on most items.

The annual membership fee and renewal

The Business membership fee varies depending on the membership tier you choose. Costco offers a standard Business membership and a higher-tier option with additional benefits. The exact cost depends on your location and current pricing, which Costco adjusts periodically. You can check the current fee on Costco.com or ask at your local warehouse.

Your membership renews automatically each year on the anniversary of your sign-up date. You can renew in person at the warehouse, online, or by phone. If you decide not to renew, you can cancel anytime and receive a prorated refund for the unused portion of your membership.

How to open a Business membership

Visit your local Costco warehouse or go to Costco.com to start the process. You'll need to bring proof of your business status—your business license, farm permit, nonprofit documentation, or reseller permit. Have your business name, address, and tax ID ready as well.

At the warehouse, a membership representative will verify your documents and set up your account on the spot. You can also start online and complete the verification in person or by uploading documents. Once approved, you'll receive your membership card and can begin shopping when ready.

Frequently Asked Questions

Can I use my Business membership at a regular Costco warehouse?

Yes. Your Business membership works at any Costco warehouse, including regular locations. You only need a Business center if one is nearby and you want access to the commercial-grade items they stock. Most Business members do most of their shopping at regular warehouses.

What's the difference between a Business membership and a Gold Star membership?

A Business membership removes purchase limits, offers lower per-unit pricing on bulk items, and includes access to Costco Business centers where available. A Gold Star membership is for personal use and may have limits on certain items during peak demand. Business membership costs more annually but saves money if you buy in bulk regularly.

Can I add employees to my Business membership?

You can add one household card holder to your account, who can make purchases on your behalf. If you need multiple employees to shop under your account, you would need to set up separate Business memberships for them, or they could shop using your household card.

Do I need a large business to get a Business membership?

No. Sole proprietors, freelancers, small farms, and nonprofits all may have access to as long as you have the required documentation. You don't need to be a corporation or have a certain number of employees. Any legitimate business, farm, or nonprofit can open an account.

What happens if my business closes?

You can cancel your membership anytime and receive a prorated refund for the unused portion of your annual fee. If your business status changes, contact Costco to update your account or discuss your options.
