Who should own the ad accounts — the business or the agency?

The business, as a default best practice — the agency should be granted admin or manager-level access under the business's own account, not the other way around, so account history, audiences, and account-level trust signals stay with the business regardless of what happens with the agency relationship.

What should count as a 'deliverable' in an agency contract?

Specific, checkable items — a defined number of ad variations per month, a reporting cadence, specific campaign types — rather than vague language like 'ongoing optimization' with no concrete, verifiable output attached to it.

What is a kill clause and why does it matter?

A kill clause defines the conditions under which either party can exit the contract early — commonly tied to missed deliverables or a defined notice period — and having one negotiated upfront avoids being locked into a long minimum term with an underperforming agency and no clear exit path.

Should creative assets belong to the business or the agency after the contract ends?

Generally the business, once paid for — this should be stated explicitly in the contract rather than assumed, since default ownership rules vary by jurisdiction and are often more favorable to the agency unless the contract specifies otherwise.

Agency Contract & Deliverables Checklist

The terms worth getting in writing before you sign — not because agencies are usually acting in bad faith, but because ambiguous contracts are where reasonable people end up in disputes later.

Agency Contract & Deliverables Checklist — key topics (Hiring Agencies guide by Zephra)

Where this sits: Stage 3 (Contract) of the Agency Relationship Operating System — the terms that make a clean future exit possible, decided while both sides still have full goodwill.

Quick Answer

Before signing, get four things explicitly in writing: the business (not the agency) owns and holds admin access to ad accounts, creative and copy assets transfer to the business once paid for, deliverables are defined as specific and checkable rather than vague, and a clear kill clause defines how either party can exit. None of this assumes bad faith — it's simply that ambiguous contracts are where reasonable disagreements later turn into real disputes.

Ownership Terms

Asset	Recommended default
Ad accounts	Owned by the business; agency granted admin/manager access under the business's own account
Creative assets and copy	Ownership transfers to the business upon payment, stated explicitly
Website/landing pages	Hosted and registered under the business's own accounts
Performance data	Export rights or a data-sharing agreement that survives contract end

These same four items are exactly what to confirm are actually in place before a transition, per Ending or Transitioning an Agency Relationship — getting them right at signing avoids a much harder negotiation later.

Sample ownership clause language (a starting point to adapt with your own counsel, not a substitute for legal review):
"All advertising accounts, including but not limited to Google Ads, Meta Business Manager, and analytics properties, shall be created under and remain the property of Client. Agency shall be granted user-level access sufficient to perform the Services and shall not create or maintain sole ownership of any such account. All creative materials, copy, and deliverables produced under this Agreement shall become the property of Client upon payment in full for the applicable period, including source files where technically available."

Worth knowing before you draft this clause: it's a non-issue with Zephra, since your accounts are yours from the start — nothing to negotiate, nothing to claim back later. See how it works, free.

Defining Deliverables Specifically

Vague deliverable	Specific deliverable
"Ongoing optimization"	"Weekly bid and budget review, monthly creative refresh"
"Regular reporting"	"Biweekly check-in call, monthly written report covering [specific metrics]"
"Content creation"	"4 ad creative variations per month per active campaign"

Specific, checkable deliverables also make the Review stage of the Agency Relationship Operating System meaningfully easier — there's something concrete to check against, not a subjective impression of effort.

Kill Clauses and Minimum Terms

A kill clause defines the conditions under which either party can exit early — commonly tied to missed deliverables, a defined notice period (see Ending or Transitioning an Agency Relationship for typical ranges), or a performance threshold. Negotiating this upfront, while both sides have full goodwill and no dispute has occurred, is meaningfully easier than trying to add one after a relationship has already soured.

Sample notice/termination clause language:
"Either party may terminate this Agreement for convenience upon [30/60] days' written notice. Upon termination, Agency shall, within [10] business days, provide Client with full account access transfer, all creative assets and deliverables produced to date, and export access to historical performance data covering the engagement period."

Reporting Obligations

The contract should specify reporting frequency and, ideally, what a report must include — not just that reporting will happen. This connects to what a healthy report actually looks like per Managing Your Marketing Agency, and having it specified contractually gives you standing to push back if reports drift toward vague, low-effort summaries.

Data Handling and Privacy

Confirm how customer data accessed during the engagement will be handled, stored, and disposed of after the contract ends — particularly relevant for businesses handling health, financial, or other sensitive customer data, where the agency's data practices become the business's own compliance exposure.

Variations by Engagement Type

Engagement type	Contract emphasis
Small monthly retainer	Ownership terms and a short notice period matter most; deliverables can be lighter-touch
Large annual contract	Detailed deliverables and a formal kill clause tied to performance thresholds
Project-based (e.g. website build)	Milestone-based deliverables and clear final-asset ownership on completion

Case Study

A business signed a 12-month agency contract with no explicit ad account ownership clause. When the relationship soured at month six, the agency was slow to transfer account access, citing an internal policy the contract hadn't addressed either way — the resulting delay cost several weeks of paused campaign management during an already difficult transition. The business's next agency contract explicitly specified business-owned ad accounts with agency access only, avoiding a repeat of the same dispute.

Decision Matrix

Situation	Priority
About to sign a new agency contract	Confirm all four ownership items explicitly before signing
Already under contract without these terms specified	Request an addendum clarifying ownership and deliverables
Considering a long minimum term	Negotiate a kill clause tied to specific, checkable deliverables first

Common Mistakes

Signing without explicit ad account and creative ownership terms.
Accepting vague deliverable language like "ongoing optimization" with nothing checkable behind it.
No kill clause, leaving no clear exit path if the relationship underperforms.
Not addressing data handling and privacy obligations in writing.

Troubleshooting

Already under contract with vague terms: request a written addendum clarifying ownership and deliverables rather than waiting until a dispute arises.

Agency resists specifying deliverables concretely: treat this as a data point on how the relationship will likely go — a confident agency should be comfortable with specific, checkable commitments.

Contract Checklist

☐ Ad accounts owned by the business, agency granted access only
☐ Creative assets and copy transfer to the business upon payment
☐ Deliverables defined specifically, not vaguely
☐ Reporting frequency and content specified
☐ A kill clause and notice period defined
☐ Data handling and privacy obligations addressed in writing
