Maria runs a growing skincare brand. She hires a marketing agency to manage ads, speak to influencers and negotiate placements with online retailers. A month later, an influencer says the agency promised a 12-month paid partnership on Maria's behalf - but Maria never approved it.
That situation is exactly why an agency agreement matters. When someone acts for your business, you need to be clear about two separate things: what services they'll perform, and whether they have legal authority to commit your business to anything.
The good news is that this doesn't have to be complicated. A well-drafted agency agreement or marketing services agreement can set expectations early, protect both sides and avoid the awkward question of who had permission to say yes.
What Is An Agency Agreement?
An agency agreement is a contract that sets out how one party will act for another party, including the services, payment terms, decision-making powers and limits on authority.
In everyday business language, people use the term in a few different ways. You might hear:
- Agency agreement - a broad term for a contract where an agent performs work or acts for a principal.
- Agency contract - another name for the same type of arrangement.
- Agency services agreement - often used when the agency is providing services like marketing, sales, creative work or management.
- Marketing agency agreement - a services agreement tailored to advertising, social media, campaigns, content and media buying.
The key point is that the word "agency" can mean two different things.
First, it can describe a service provider. For example, a digital agency may create ads, write copy and manage your campaigns.
Second, it can describe legal authority. An agent with legal authority may be able to bind your business to contracts, make promises to customers or negotiate deals that your business has to honor.
Your agreement should make that distinction very clear. Otherwise, one side may assume the agency can make decisions, while the other side expects every major commitment to be approved first.
Does An Agency Agreement Give Someone Authority To Bind Your Business?
It depends - an agency agreement can give someone authority to bind your business, but it doesn't have to.
Under general US agency law principles, a person may be able to act for your business if they have actual authority, apparent authority or authority that's later approved. State law affects the details, so the exact position can vary depending on your circumstances.
Actual Authority
Actual authority means you've clearly authorized the agent to do something. This can be written into the agreement, given verbally or implied from the role you've asked them to perform.
For example, you might authorize a sales agent to sign purchase orders up to $10,000, but require written approval for anything above that amount.
Apparent Authority
Apparent authority is riskier because it can arise from how things look to outsiders. If your business presents someone as having authority, a third party may argue they reasonably believed that person could act for you.
Say you let an agency use your business email address, negotiate directly with vendors and say they're your "brand partner" with no limits explained. If they agree to a deal, the vendor may argue your business should be bound because you allowed the agency to appear authorized.
Approval After The Fact
You may also become bound if you later approve or accept the benefit of something the agency did without permission. For example, if an agency books a campaign outside its authority and you accept the campaign results without objecting, it may be harder to say you never agreed.
This is why your agency agreement should say exactly what the agency can and can't do, and how approvals must be given.
What Should Be Included In An Agency Services Agreement?
An agency services agreement should include the services, fees, timelines, authority limits, client responsibilities, intellectual property, confidentiality, legal compliance and termination rights.
The more practical your agreement is, the easier it's to use when something changes or goes wrong. Templates often miss the details that matter most for your specific business model, especially around authority and approvals.
Services And Deliverables
Spell out what the agency is actually doing. For a marketing agency agreement, this might include:
- campaign strategy
- social media management
- ad creative and copywriting
- email marketing
- search engine ads
- influencer outreach
- reporting and analytics
- website landing pages
Try to avoid vague promises like "manage marketing" or "grow sales." If targets are aspirational rather than guaranteed, say that clearly.
Approval Process
Your agreement should say who approves work and how approvals happen. This is especially important for ad spend, public statements, discounts, influencer terms, co-marketing terms, customer communications and brand claims.
You might require written approval before the agency:
- spends more than a set budget
- publishes content using your brand name
- contacts key customers or partners
- offers refunds, credits or discounts
- signs any contract or order form
- uses testimonials, endorsements or before-and-after claims
For practical purposes, "written approval" can include email if the contract says so. Just be clear about whether Slack, text messages or project management comments count.
Fees, Expenses And Payment Terms
Set out the pricing model from the start. Common options include a monthly retainer, hourly rates, project fees, commission, performance bonuses or a mix of these.
Your agreement should also cover:
- when invoices are issued
- when payment is due
- whether late fees apply
- which expenses need pre-approval
- whether third-party costs are passed through at cost or marked up
- what happens if the client pauses or delays work
Without clear payment terms, you may struggle to recover unpaid invoices or justify extra charges for work outside the original scope.
How Do You Limit An Agent's Authority?
You limit an agent's authority by writing clear restrictions into the agency agreement and making sure third parties aren't given a different impression.
The contract is only part of the picture. Your behavior matters too. If the written agreement says the agency can't bind you, but you let them sign vendor paperwork for months without correction, your conduct can create confusion.
Useful safeguards include:
- No authority clause: state that the agency can't sign contracts, make legal commitments or incur liabilities unless you give prior written approval.
- Approval thresholds: set dollar limits for ad spend, discounts, vendor costs or purchase commitments.
- Named approvers: list the people in your business who can approve key decisions.
- Third-party notices: require the agency to tell vendors, platforms and partners that it doesn't have signing authority.
- Email and branding rules: control whether the agency can use your email domain, logos, signatures or titles.
- Delegation limits: stop the agency from subcontracting work or appointing others without approval.
For example, if Mike's cleaning supply company hires a sales agency, the agreement might let the agency introduce leads and negotiate draft terms, but not sign customer contracts. Mike's team would then issue the final customer agreement directly.
That simple structure helps everyone understand the agency's role. The agency can still do valuable work, but your business stays in control of the legal commitments.
What Laws Can Affect A Marketing Agency Agreement?
Several laws can affect a marketing agency agreement, especially federal advertising, intellectual property and confidentiality laws.
If the agency is running ads or creating content for your business, the agreement shouldn't just describe the services. It should also allocate responsibility for legal compliance.
Advertising And Consumer Claims
The Federal Trade Commission Act prohibits unfair or deceptive acts or practices. In practice, that means marketing claims should be truthful, not misleading and supported by evidence where needed.
FTC guidance is especially relevant for:
- influencer endorsements and disclosures
- testimonials and reviews
- health, wellness or performance claims
- environmental or sustainability claims
- pricing and discount advertising
- paid social media content
Your agreement should say who checks claims, who approves final content and who is responsible if the agency publishes something that wasn't approved.
Trademarks And Brand Use
The Lanham Act governs federal trademark rights and false advertising claims. If the agency uses your brand name, logo or product names, your agreement should set brand guidelines and limits.
You should also be careful with competitor names, comparison ads and keywords. These can be lawful in some situations, but the details matter and the wrong campaign can trigger a dispute.
Copyright Ownership
Under the US Copyright Act, the creator of original content usually owns the copyright unless there's a valid written assignment or the work qualifies as a work made for hire. The work made for hire rules are narrow, so don't assume paying for work automatically gives you ownership.
Your agreement should say who owns:
- ad copy
- graphics and videos
- photography
- website content
- campaign concepts
- source files and editable files
- reports, strategy decks and templates
If you need full ownership, include a written assignment. If the agency keeps ownership and gives you a license, the license should say what you can use, where, for how long and whether you can edit it.
Confidential Information And Trade Secrets
The Defend Trade Secrets Act can protect trade secrets at the federal level, but you still need to handle confidential information carefully. Your agreement should restrict how the agency uses customer lists, pricing, launch plans, data, financial information and internal processes.
Strong confidentiality terms can also make it easier to protect your business if sensitive information is misused.
What Are The Client's Obligations Under An Agency Contract?
The client's obligations usually include providing information, giving timely approvals, paying fees and making sure the agency has what it needs to perform the services.
Agency contracts work best when they don't put all obligations on one side. If you're the client, the agency may need access to brand assets, ad accounts, product details, customer insights and compliance requirements.
Common client obligations include:
- providing accurate information about products, prices and availability
- reviewing and approving work within a set timeframe
- giving access to platforms, files and accounts
- telling the agency about legal or industry restrictions that affect your business
- paying invoices on time
- not asking the agency to use third-party content without permission
- appointing one main contact person for decisions
If you're the agency, these obligations protect you from being blamed for delays caused by the client. If you're the client, they help you get better service and avoid misunderstandings about who is responsible for what.
For products or services covered by industry-specific rules, you may need more tailored terms. Health, finance, alcohol, education and professional services can all have extra advertising or licensing requirements, and those rules may also vary by state.
How Can You End An Agency Agreement?
You can end an agency agreement by following the termination clause, which should set out notice periods, payment on exit, handover steps and what happens to work in progress.
There's no single federal notice period that applies to every agency agreement. The notice period is usually whatever the contract says, subject to state law and any industry-specific rules.
Common termination options include:
- Termination for convenience: either party can end the agreement with written notice, often after an initial minimum term.
- Termination for cause: one party can end the agreement if the other materially breaches the contract and doesn't fix it within the agreed cure period.
- Immediate termination: used for serious issues like non-payment, misuse of confidential information, fraud, insolvency events or conduct that harms the brand.
- Project completion: the agreement ends when a campaign or project is completed and final invoices are paid.
Your exit terms should cover practical handover items, such as:
- returning passwords and admin access
- transferring ad accounts or creative files
- removing brand materials from agency systems
- paying approved third-party costs
- confirming which content the client can keep using
- keeping confidentiality obligations in place after termination
If the agency manages critical accounts, don't wait until the final week to sort out access. Make sure your business owns or controls key platform accounts from day one, even if the agency manages them day to day.
Common Mistakes To Avoid
The most common mistake is treating an agency services relationship as a handshake arrangement, then discovering too late that each side had different expectations.
Here are the issues we see cause the most friction:
- Not separating services from authority: the agency can perform services without having power to legally bind your business.
- No written approval process: without a clear process, you may argue later about whether a campaign, spend or commitment was approved.
- Assuming you own the work: payment doesn't always equal copyright ownership under the Copyright Act.
- Ignoring ad compliance: the FTC Act and FTC guidance can apply to claims, reviews, endorsements and pricing promotions.
- Leaving account access with the agency: your business should control core accounts, data and admin permissions where possible.
- Using vague performance promises: be careful with guarantees around revenue, leads, rankings or conversion rates unless the promise is measurable and realistic.
- Forgetting about confidentiality: agencies often see sensitive business information, so confidentiality and trade secret protections matter.
A good agreement won't stop every commercial issue, but it gives you a clear process for dealing with them before they become expensive disputes.
Frequently Asked Questions
Is An Agency Agreement The Same As A Contractor Agreement?
No, not always. A contractor agreement usually focuses on services, while an agency agreement may also deal with authority to act for or represent your business. Some agreements do both.
Can An Agency Use Subcontractors?
Yes, if the agreement allows it. If subcontractors may be used, your contract should say whether you need to approve them and whether the agency remains responsible for their work.
Who Owns The Ad Accounts And Campaign Data?
Ideally, your business should own or control key ad accounts and data, even if the agency manages them. Put this in the agreement so access and handover are clear.
Do I Need A Written Agreement For A Small Monthly Retainer?
Yes, it's still worth having one. Smaller retainers can still involve brand risk, customer data, ad spend, intellectual property and payment disputes.
Key Takeaways
- An agency agreement should clearly explain both the services being provided and whether the agency has authority to bind your business.

- Clear limits on authority help reduce the risk that a third party thinks the agency can sign contracts or make binding promises for you.
- Termination terms should cover notice, unpaid fees, handover, account access, confidential information and ongoing use of content.
