What Should Be In A Marketing Agency Contract

Updated September 2026 · Written and maintained by the Progression Agency strategy team

Agency agreements are drafted by agencies, and the terms that matter most are the ones that only become relevant at the end. This page covers ownership of accounts, work and data; how scope is defined by what it excludes; why notice matters more than term; what sits outside the fee; data and privacy obligations; the clauses people sign unread; and the handover clause almost nobody drafts. General information, not legal advice.

The short answerFour amendments cover most of the risk: ownership of accounts, work and data; the notice period; what sits outside the fee; and a handover clause naming what you receive and within how many days. The advertising account in particular should sit in a business manager you own, with the agency granted access — otherwise years of optimization history belongs to them. If an agency will adjust none of the four, that is itself the finding.

The four that matter most

This page describes commercial terms commonly found in agency agreements and what each one does. It is general information, not legal advice, and contract law varies by jurisdiction. Have anything you intend to sign reviewed by a qualified lawyer.

Ownership is the clause that costs the most to get wrong

Every other term is renegotiable while the relationship lasts. Ownership only matters at the moment the relationship ends, which is exactly when nobody is inclined to be accommodating.

Four things need naming explicitly: the accounts, the work, the data and the credentials. The advertising account should sit inside a business manager the client owns, with the agency granted access rather than holding the account. The website, domain and analytics property should be registered to the client. Work produced under the agreement should be assigned to the client on payment. And administrative credentials should never exist only inside the agency.

The failure mode is not malice. It is that an agency creates an ad account under its own business manager because that is faster on day one, and three years of history then belongs to them. Recovering it is sometimes impossible, and starting a new account discards accumulated learning the platform uses to optimize.

Ownership terms, and what each prevents
AssetCorrect arrangementWhat goes wrong without it
Ad accountsClient-owned business manager, agency granted accessYears of history stay with the agency
Domain and DNSRegistered to the clientSite can go dark during a dispute
Website and codeAssigned on payment, source deliverableNo ability to move hosts or developers
Analytics propertyClient-owned, agency added as userHistorical data lost at handover
Produced contentAssigned to client on paymentAmbiguity over reuse and republication
Third-party licensesNamed, with expiry dates recordedAssets must be pulled or relicensed

Assignment on payment, not on completion

If work is assigned only when a project completes, an engagement ending mid-way leaves ownership of everything produced unresolved.

Name raw files, not only deliverables

Editable source files, project files and raw footage should be listed explicitly. Delivering only exported outputs is a common and defensible reading of a vague clause.

Licensed material needs its own list

Stock imagery, fonts and creator content frequently carry term limits. A license that expires after twelve months affects any asset still running.

Credentials belong in a client-controlled store

Not in an individual’s password manager at the agency, and not in a shared document nobody maintains.

Scope is defined as much by what it excludes

Most scope disputes are not about whether work was done well. They are about whether it was included, and both parties held a reasonable reading of a sentence that never addressed it.

A usable scope states deliverable types and quantities, the review and revision process, who supplies inputs, and turnaround expectations in both directions. It should also state plainly what sits outside: media budget, creator and talent fees, photography and shoot days, licensing for paid usage, out-of-hours coverage, and work arising from a third party changing something.

The last of those is worth naming. Platform changes, rebrands and site migrations generate real work that no scope anticipated, and an agreement silent on it produces an argument at the worst possible moment.

Media budget — Almost always separate. Confirm before comparing fees..
Creator fees — Pass-through, not included. Ask about margin..
Shoot days — Usually quoted per day. Rarely bundled..
Paid usage rights — Licensed separately. A post is not an ad asset..
Out-of-hours — Outside the window. Matters exactly when excluded..
Third-party changes — Platform or rebrand work. Silence causes arguments..

Term and notice are separate decisions and notice matters more

A long term with short notice is more flexible than a rolling agreement with long notice, and buyers routinely negotiate the wrong one of the two.

The term sets how long the commitment runs. Notice sets how quickly either side can end it. A twelve-month term with sixty days’ notice means you can leave in two months. A rolling monthly agreement requiring ninety days’ notice means you cannot.

Check three details specifically: whether notice can be served at any point or only near renewal, whether renewal is automatic and what notice prevents it, and whether fees remain payable through the notice period even if work stops. All three are ordinary terms; all three surprise people.

Term and notice combinations
StructureReal flexibilityWatch for
12-month term, 60-day noticeCan exit in two monthsWhether notice is allowed mid-term
Rolling monthly, 90-day noticeThree months minimum, alwaysReads flexible, is not
12-month, no early exitLocked for the full termOnly acceptable at a real discount
Auto-renewing annualRolls silently if notice missedDiarise the notice deadline
Project with milestonesEnds naturally at completionWhat happens to unfinished work

Fees, and what sits outside them

The monthly number is the least ambiguous part of an agreement and the most commonly misunderstood, because what it excludes is often larger than what it includes.

Establish whether media spend is inside or outside the fee, and if the agency is paid a percentage of it, whether that percentage has a floor and a ceiling. Establish whether pass-through costs — creator fees, stock licenses, shoot days, software the agency buys on your behalf — are billed at cost or with a margin. Establish what happens to unused hours in a retainer, and whether overage is billed automatically or requires approval.

Also settle the uncomfortable one: what happens if you pause. Pausing a retainer during a slow quarter is a normal business need, and an agreement silent on it usually resolves in the agency’s favor.

Percentage-of-spend needs bounds

Without a floor the agency loses money on small accounts; without a ceiling it earns disproportionately on large ones, and neither party is well served.

Pass-through costs should be at cost

A margin on media and licenses is not unreasonable if disclosed. Undisclosed margin is the issue, and asking directly resolves it.

Unused retainer hours rarely roll

Most agreements state that they do not, which is defensible since capacity was reserved. It should be stated rather than discovered.

Price increases need a mechanism

An annual review clause with notice is normal. Unilateral increases at any time are not.

Reporting and access obligations belong in the agreement

What you are entitled to see, and how often, is a commercial term rather than a courtesy. Agreements that leave it unstated produce the common situation where reporting quietly degrades and there is nothing to point to.

Specify the reporting cadence, the measures it will contain, and — more usefully — that you retain direct read access to the underlying platforms rather than receiving only the agency’s summary of them. Direct access costs the agency nothing and removes any question about whether numbers have been selected favorably.

It is also worth stating that access survives any dispute. Access being withdrawn during a disagreement is the scenario the clause exists to prevent, and it is precisely when goodwill cannot be relied on.

Access terms worth writing down
AccessWhy it mattersCommon default
Direct platform read accessRemoves reliance on a curated summaryAgency-only access
Analytics adminLets you add or remove anyoneAgency holds admin
Billing visibilityConfirms actual media spendReported, not visible
Access survives disputesThe moment you most need itUnaddressed
Named reporting cadenceSomething to point to if it slipsBest efforts

Data, privacy and who is responsible for what

Any agency touching customer data, running advertising or operating your analytics is processing personal information on your behalf, and the agreement should say so explicitly.

The practical items are a data processing clause describing what they may do with customer data, a prohibition on using your data to benefit other clients, a requirement to notify you promptly of any breach, and a commitment to delete or return data at the end of the engagement. Where audience lists are uploaded to advertising platforms, ownership and deletion of those lists should be named too.

Regulatory obligations sit with you as the business collecting the data, regardless of who operates the systems. An agency’s assurance is not a transfer of responsibility, which is why the clause should require them to support compliance rather than claim to provide it.

What a handover clause should name
Most agreements describe onboarding in detail and termination in one sentence.

Confidentiality, exclusivity and non-solicitation

These three appear in most agreements, are frequently signed unread, and have real consequences.

Confidentiality should be mutual. An agreement binding only the client is unusual and worth questioning. Exclusivity — a commitment not to work with your direct competitors — is reasonable to request and usually commands a premium; if granted, define the competitor set precisely, because a vague definition is unenforceable and pointless.

Non-solicitation clauses preventing you from hiring the agency’s staff are standard. What matters is the duration and whether it applies to people who approach you independently. A twelve-month restriction on people who worked on your account is ordinary; an indefinite restriction covering the entire agency is not.

Clauses people sign without reading
ClauseOrdinary versionWorth pushing back on
ConfidentialityMutual, defined termOne-directional
ExclusivityDefined competitor set, pricedVague sector-wide exclusion
Non-solicitation12 months, account team onlyIndefinite, whole agency
Auto-renewalWith a clear notice windowSilent roll with long notice
Liability capCapped at fees paidUnlimited client liability
Governing lawA jurisdiction you can reachSomewhere impractical to litigate

The termination and handover clause is the one nobody drafts

Most agreements describe how the relationship starts in detail and how it ends in a sentence. Reversing that emphasis is the single most useful change a buyer can make.

The clause should name what you receive on termination, in what format, and within how many days. That means account access transferred rather than merely granted, source and raw files delivered, documentation of what is running and where, credentials handed over, and any scheduled or automated activity disclosed so it can be stopped or continued deliberately.

It should also state what happens to work in progress, whether final invoices are due before or after handover, and whether the agency will support a transition period. An agency that resists specifying this is describing what leaving will be like.

Account transfer — Ownership, not access. Access can be revoked..
Raw files — Editable, not exports. Name them explicitly..
Credentials — To a client-owned store. Not an individual's manager..
What is running — Documented. Including anything scheduled..
Work in progress — Delivered or not. Usually unaddressed entirely..
A deadline — In days. Otherwise it never happens..

Indemnities, and the risks that actually arise

Indemnity clauses read as boilerplate and describe genuine allocations of risk. Two situations arise often enough in marketing work to be worth understanding.

The first is intellectual property. If an agency uses an image, font, typeface or piece of music without the correct license and a rights holder objects, the claim usually lands on the business that published it. An indemnity from the agency for infringement arising from material they supplied is a reasonable request.

The second is regulatory. Advertising claims are the advertiser’s responsibility, and an agency writing copy does not become liable for a claim you approved. Expect to indemnify the agency for information you supplied and for claims about your own product, and expect them to indemnify you for rights in material they produced. That split is the ordinary one.

What to fix before signing, in priority order

Few buyers have the leverage to rewrite an agency’s standard agreement, and most do not need to. A small number of amendments cover most of the risk.

In order: ownership of accounts, work and data; notice period; what sits outside the fee; and the handover clause. Those four determine what happens in the situations that actually cause difficulty. Everything else is comparatively minor, and negotiating it can consume goodwill better spent on the four that matter.

If an agency accommodates none of the four, that is itself the finding. Standard terms are standard because they suit the party who wrote them, and willingness to adjust the ownership and handover clauses is a reliable signal about how the relationship will be run.

Frequently asked questions

What should be in a marketing agency contract?
Ownership of accounts, work and data; a scope that states what is excluded as well as included; term and notice as separate terms; what sits outside the fee; data processing obligations; and a handover clause naming what you receive on termination and within how many days. Those six cover most of what causes difficulty.
Who should own the advertising account?
You should, with the agency granted access. The account belongs inside a business manager you control. Agencies frequently create accounts under their own because it is faster on day one, and years of optimization history then belong to them.
What is a normal notice period for an agency contract?
Thirty to ninety days is the usual range, and it matters more than the contract term. A twelve-month term with sixty days’ notice is more flexible than a rolling monthly agreement requiring ninety days.
Should I sign a twelve-month agency contract?
A twelve-month term is reasonable when notice allows earlier exit and the price reflects the commitment. A twelve-month term with no early exit should come with a meaningful discount, since you are carrying all of the risk.
Does the agency own the content they produce for me?
Only if the contract says so, and many standard agreements are silent or reserve rights. Ask for assignment to you on payment, and name raw and editable files explicitly — delivering only exported outputs is a defensible reading of a vague clause.
What should the handover clause say?
What you receive, in what format, and within how many days: account access transferred, source and raw files, documentation of what is running, credentials, and disclosure of any automated activity. Most agreements describe onboarding in detail and termination in a sentence.
Is exclusivity worth asking for?
It is reasonable to request and usually commands a premium. If granted, define the competitor set precisely — a vague sector-wide exclusion is unenforceable and therefore worth nothing to either side.
What is a pass-through cost?
A cost the agency incurs on your behalf and bills onward: creator fees, stock licenses, shoot days, software. Establish whether these are billed at cost or with a margin. Disclosed margin is defensible; undisclosed margin is the problem.
Can I pause a retainer?
Only if the agreement provides for it, and many do not. Pausing during a slow quarter is a normal business need, and an agreement silent on it usually resolves in the agency’s favor. Raise it before signing rather than when you need it.
Do unused retainer hours roll over?
Usually not, and most agreements say so. That is defensible because capacity was reserved for you. What matters is that it is stated in the contract rather than discovered in month four.
What data clauses do I need?
A processing clause describing permitted use, a prohibition on using your data for other clients, prompt breach notification, and deletion or return at the end. Where audience lists are uploaded to ad platforms, name ownership and deletion of those lists specifically.
Is the agency responsible for privacy compliance?
You remain responsible as the business collecting the data, regardless of who operates the systems. The clause should require the agency to support compliance rather than claim to provide it, because the obligation cannot be transferred by contract.
What is a reasonable liability cap?
Capping the agency’s liability at fees paid is common and generally accepted. What is worth questioning is an agreement that caps their liability while leaving yours uncapped.
Should the contract name specific people?
Naming the account team and their approximate time allocation is a fair request and reduces the common pattern of senior people pitching and juniors delivering. Expect a substitution clause allowing replacement with equivalent seniority.
What happens to work in progress if we terminate?
Whatever the contract says, which is frequently nothing. Specify it: whether partially completed work is delivered, whether it is assigned to you, and whether it is invoiced. This is a common source of dispute precisely because it is usually unaddressed.
Can an agency raise prices mid-contract?
Only where the agreement permits it. An annual review clause with notice is normal; a right to increase unilaterally at any time is not, and is worth amending before signing.
How long should I get to review a contract?
As long as you need, and pressure to sign quickly is itself informative. A few days for a lawyer to review terms you will live with for a year is an ordinary request.
Which clauses should I prioritize if I have limited leverage?
Ownership, notice period, what sits outside the fee, and handover. Those four determine what happens in the situations that actually cause difficulty, and negotiating minor terms can consume goodwill better spent on them.
What if the agency refuses to change anything?
Treat that as information. Standard terms suit whoever wrote them, and willingness to adjust ownership and handover specifically is a reliable signal about how the relationship will be run.
Do I need a lawyer to review an agency contract?
For anything with a meaningful annual value, yes. This page describes what terms do; it is not legal advice, contract law varies by jurisdiction, and the cost of review is small against the cost of a badly drafted ownership clause.
