Can You Use Customer Logos on Your Website in the US?

Customer logos can make a B2B website feel credible fast. A row of recognizable brands tells prospects that real companies have trusted your product, software or service. The legal risk is that a logo is usually someone else's trademark, and using it without clear permission can create confusion about endorsement, partnership or approval.

Common mistakes include copying logos from a customer's website, assuming a sales email is enough consent, adding logos after a free trial, or using a logo after the customer relationship has ended. Some companies also forget that their own customer agreement may be silent, or may even prohibit publicity without written approval.

A careful approach helps you decide when customer logo trademark use is low risk, when you need express logo usage consent, and what contract language should say before your marketing team updates the homepage.

Customer Logo Website Checklist

You should usually get written permission before using a customer logo on your website, unless your customer terms already give you a clear publicity right that covers the exact use.

For most B2B companies, customer logos are not just decorative design assets. They signal that a named organization bought, used or approved your business. That is why the safest process is a short legal and commercial check before publishing.

• Confirm the relationship is real. The company should be an actual customer, not only a prospect, pilot user, expired account or informal referrer.
• Review the signed contract. Look for customer name, logo, publicity, case study, confidentiality, brand use, trademark and marketing approval clauses.
• Check for approval requirements. Many enterprise customers require prior written approval from legal, marketing or brand teams before any public use.
• Limit the claim. A logo wall usually says less than a testimonial or case study, but it can still imply endorsement if presented too strongly.
• Use the correct logo file. Ask for an approved brand asset or brand guidelines rather than screenshotting, stretching, recoloring or modifying the logo.
• Keep records. Save the signed agreement, email approval, brand instructions and the version of the webpage where the logo appears.
• Set an internal removal trigger. Remove the logo if the customer relationship ends, permission is revoked, the customer changes brand rules, or the contract requires it.

A practical example is a SaaS company launching a new enterprise page. If its master subscription agreement says the vendor may identify the customer by name and logo in customer lists and on its website, subject to brand guidelines, the marketing team may be able to use the logo within those trademark license limits. If the agreement says neither party may issue publicity without written consent, the team should get separate permission before publishing.

Another example is a consultancy that completed a successful project for a large manufacturer. Even if the client praised the work in meetings, a homepage logo and statement such as "trusted by" can go beyond private feedback. A short written approval is much safer than relying on a friendly relationship with one business contact.

Why Customer Logos Can Raise Trademark and Publicity Issues

A customer logo is usually protected as a trademark, and your use can be risky if it suggests sponsorship, affiliation or endorsement that the customer has not approved.

In the United States, the federal Lanham Act is the main law governing trademark infringement and false association. The core question is often whether your use is likely to confuse customers about the source, sponsorship, approval or affiliation of your services. A logo on a B2B website can create that impression, especially if it appears near strong claims like "partners," "certified by," "approved by" or "official clients."

Trademark rights can exist even without a federal registration, but many customer logos are also registered with the U.S. Patent and Trademark Office. A registration gives the owner stronger tools to object to unauthorized brand use. That does not mean every appearance of a logo is automatically unlawful, but it does mean casual copying is not a good business process.

There are several legal theories that can come up when using client logos on a website:

• Trademark infringement. The customer may argue your logo use is likely to cause confusion about endorsement, partnership or approval.
• False association or false endorsement. Even if no one thinks you own the customer's brand, the presentation may imply the customer publicly backs your product.
• Trademark dilution. Famous brands may object to uses that blur or tarnish their distinctive brand, even without ordinary consumer confusion.
• Copyright issues. Some logos contain artwork that may be protected under the Copyright Act, although not every simple wordmark or symbol qualifies.
• Right of publicity issues. If your marketing includes names, photos, quotes or videos of identifiable people, state publicity laws may require separate consent.
• Contract breach. Your agreement may restrict publicity, confidentiality or use of the customer's trademarks.

Website context matters. A neutral customer list may be easier to justify than a prominent banner saying a customer "recommends" or "backs" your platform. A logo next to a factual statement such as "selected customers" may carry less risk than a logo placed beside a detailed performance claim that the customer has not reviewed.

The Federal Trade Commission can also matter where the logo use functions like an endorsement or testimonial. Under the FTC Act and FTC endorsement guidance, advertising should not mislead customers about endorsements or material relationships. If a logo or quote suggests a customer recommends your service, the statement should be truthful, substantiated and not taken out of context.

Right of publicity laws are mostly state law, and they vary. A company logo is not a person's likeness, but customer marketing often expands from logos into executive quotes, headshots, video testimonials or named case studies. Those uses need their own consent from the business and, where relevant, the individual featured.

When Contract Permission Is Required

Contract permission is required whenever your customer agreement says publicity needs approval, prohibits brand use, treats the relationship as confidential, or fails to clearly authorize the logo use you want.

Many B2B disputes about logo use are really contract disputes. The customer may not need to prove complex trademark harm if the contract simply says you cannot use its name or marks without prior written consent. Business owners should treat the contract as the first source of rules before analyzing broader trademark law.

Common clauses to look for include:

• Publicity clauses. These clauses say whether either party can refer to the other publicly, including on websites, pitch decks, press releases and customer lists.
• Trademark or brand use clauses. These clauses may allow limited use of names and logos, often subject to brand guidelines and quality control.
• Confidentiality clauses. If the identity of the customer or the existence of the relationship is confidential, a logo wall may breach the agreement.
• No endorsement language. Some contracts allow factual references but prohibit suggesting endorsement, recommendation or partnership.
• Approval processes. Some contracts require written approval for each use, or approval of final copy, layout and logo placement.
• Termination rights. The contract may require logo removal when the agreement ends or when the customer asks.

Silence is not ideal. If your customer agreement says nothing about marketing rights, that does not automatically give you permission to use the customer's logo. You might have a practical argument that a factual customer reference is fair in limited circumstances, but it is rarely the cleanest position for a growing company trying to keep customers happy.

Enterprise procurement teams often care about this issue. A customer may accept your standard terms but insist on deleting any clause that lets you use its logo. Government agencies, healthcare organizations, financial institutions, education providers and heavily regulated companies may have strict vendor publicity policies. Industry rules and customer-specific policies can change the answer even when federal trademark law would otherwise look manageable.

Sales materials deserve the same attention as the public website. A logo in a private investor deck, proposal, conference booth, app marketplace listing or email campaign can still be a public or commercial use. If a contract only permits logo use "on the vendor's website," do not assume it also covers trade show banners or paid ads.

Pay attention to who signed off. A customer success manager may be happy for you to use the logo, but the contract may require approval by an authorized representative, the legal department or brand team. For a smaller customer, an email from the founder may be enough commercially. For a large organization, relying on an informal chat message can create friction later.

How to Get Logo Usage Consent That Works

Good logo usage consent should identify the customer, the specific trademarks, the permitted marketing channels, the approval process, usage limits and removal rights.

Consent does not always need to be a long document. It can be built into your master services agreement, order form, customer terms, subscription agreement, marketing services agreement or a separate short release. What matters is that the wording is clear enough for your marketing team to rely on and clear enough for the customer to understand.

A useful permission clause often covers:

• Who may use the logo. Name your company and any relevant affiliated business that operates the website or marketing channel.
• What may be used. Refer to the customer's name, trademarks, logo and approved brand assets.
• Where it may appear. Specify your website, customer list, sales materials, investor materials, social media, case studies or press releases as applicable.
• Purpose of use. Limit the use to identifying the customer as a current or past customer, or promoting the business relationship.
• Approval rights. State whether prior approval is required for each use, only for case studies and press releases, or not required if brand guidelines are followed.
• Brand guidelines. Require use in accordance with the customer's reasonable brand guidelines and approved logo files.
• No ownership transfer. Acknowledge that the customer owns its trademarks and that you receive only a limited permission.
• No misleading endorsement. Avoid suggesting sponsorship, certification or recommendation unless the customer has specifically approved that message.
• Removal process. Explain when you must remove the logo, such as after termination, upon reasonable written request, or after a defined notice period.

For example, a balanced clause might allow you to display the customer's name and logo on your website and in sales materials solely to identify the customer as a user of your services, subject to the customer's reasonable brand guidelines. It might also say you will remove the logo within a reasonable time after receiving a written request. That kind of language is usually more acceptable than a broad right to use the customer's marks for any marketing purpose.

Separate approval is usually better for high-impact marketing. A logo wall is one thing. A detailed case study with performance metrics, a named quote from a vice president, an endorsement agreement and a paid social media campaign is another. For case studies, confirm the final text, data points, quotes, photos and distribution channels before publication.

Keep consent organized. Store approvals in your contract management system or customer record, not only in a salesperson's inbox. If a customer asks why its logo appears online, you should be able to find the relevant clause or approval quickly.

When a customer refuses logo use, respect that decision. You can still build credibility through anonymized examples, industry descriptors, aggregate statistics, product screenshots without customer branding, or testimonials from customers who are comfortable being named. A forced logo placement can damage a valuable commercial relationship.

Review existing website logos after major company changes. If you acquire a business, rebrand, change your product, shift into a new industry, or start using paid ads around the logo wall, older consents may no longer fit the current use. The same applies if your customer is acquired, changes its brand or adopts new vendor publicity rules.

FAQs

Can I Use Customer Logos on My Website Without Asking?

Usually, you should ask or rely on a clear contract clause that already gives permission. Even if the customer is happy with your service, a logo on a website can imply endorsement or affiliation. Written permission reduces trademark, contract and relationship risk.

Is It Enough to List the Customer's Name Without the Logo?

Using only the customer's name can be lower risk than using a logo, but it is not risk-free. The customer's name may still be a trademark, and your contract may restrict public references to the relationship. Confidential customers should not be named without permission.

Can We Use a Logo If the Customer Gave Us a Testimonial?

A testimonial does not automatically include permission to use the customer's logo. Get consent that covers the testimonial text, the person's name and title, the company name, any logo, and the channels where the testimonial will appear.

What If a Customer Asks Us to Remove Its Logo?

Check the contract first, but in many cases the practical answer is to remove it promptly. Even where you believe you have permission, a fast removal can avoid escalation and preserve the relationship while you clarify rights.

Do We Need Permission for Logos in Pitch Decks?

Often, yes. A private pitch deck may still be a commercial use, and it may be shared beyond the room. If your contract limits logo use to your website, get separate consent before using customer logos in investor, sales or partnership materials.

Key Takeaways

• Customer logos are usually trademarks, so website use can raise Lanham Act issues if it implies endorsement, sponsorship or affiliation without permission.
