You should own all of it. Brand Registry belongs to the trademark holder, the ad data lives inside your Seller Central account, and an agency should work through revocable user permissions on your login. If any of those sit under an agency account instead, you are renting your own brand.
The short version
- The trademark is the root of everything. Whoever holds it controls Brand Registry, and Brand Registry controls A+ content, Stores, and brand analytics.
- Ad history is an asset. Years of keyword and placement data is worth more than the campaigns themselves.
- Permissions, not logins. Grant a user, do not share a password, and revoke on the day you part ways.
- Ask before you sign, not on the way out. Ownership questions are cheap in week one and expensive in month fourteen.
- Internal tooling is theirs. Outputs are yours. That line is reasonable, and it should be written down.
Grant access, do not transfer it
Here is the instruction, then the reasoning. Open the account in your own company name, file the trademark in your own company name, complete Brand Registry yourself, and then invite the agency as a user with defined permissions. Never let a service provider create the asset in their name with a promise to move it later.
The reasoning is that every valuable thing in an Amazon business is downstream of those two registrations. Brand Registry unlocks A+ content, the Store, brand analytics, and the reporting tools that make advertising decisions possible. Brand Registry itself is unlocked by the trademark. If the trademark sits in an agency's name, the transfer at the end is a legal assignment they have to agree to, on their timeline, possibly at a price.
Three arrangements, compared
| You own the account | Agency owns the account | Split ownership | |
|---|---|---|---|
| Trademark holder | You | The agency or a related entity | You, usually |
| Brand Registry admin | You, agency invited as a user | The agency | Contested in practice |
| Ad data on exit | Stays in your account | Leaves with them | Partial export at best |
| Time to switch providers | Same day, revoke permissions | Weeks or months | Weeks, plus a dispute |
| What you are actually buying | Management | Distribution | Ambiguity |
The decision rule
Choose the first column unless somebody is buying your inventory outright and reselling it, which is a fundamentally different relationship with a different name. For a management engagement there is no defensible reason for the agency to hold the account. If you are told otherwise, the reason will be framed as convenience, and the effect will be leverage.
Flapen works only on the client's own account through granted user permissions, revocable at any time. On exit the client keeps the Seller Central account, the campaigns, the creative, and a written handover. I do not present that as unusual generosity. It is the baseline, and it should be yours.
The data most sellers forget to ask about
Campaigns are easy to see. The valuable layer underneath is less visible.
- Search-term history. Which queries converted, at what cost, over which seasons. This is the input to every future campaign structure.
- Validation results. If a partner ran a test batch for you, that data is a real asset. A typical first phase is 200 units at $5,000 to $10,000, testing up to four products at once, and it produces a conversion rate, a return rate, and a customer acquisition cost you paid for. Ask who keeps the raw numbers.
- Creative source files. Layered files, not flattened images. Deliverables should become your intellectual property on full payment.
- Supplier and quality-control records. Inspection reports and specification sheets belong with the brand.
The tooling exception
An agency's own software is not yours, and asking for it is not reasonable. We build advertising, marketing, and brand valuation tools internally, and those stay with us the same way any firm keeps its methods. The line that matters is the outputs. Every campaign, asset, report, and data export that touches your account must be yours, exportable, and useable without our software. Ask for that sentence in the agreement.
Sizing before signing
One habit worth carrying into the ownership conversation: a partner who has done proper research before quoting will already know why your data matters. We use a $2 million a year minimum market size as an entry floor, because below that there is not enough revenue to capture profitably once customer acquisition costs are paid. That analysis depends entirely on historical account and category data. An agency that never asks for your data before quoting is not analyzing anything.
What most agencies will not tell you about access
There is a quiet version of lock-in that has nothing to do with contracts. It happens when the campaign structure, the naming conventions, and the reporting all live inside a proprietary dashboard, so a technically correct export lands as a spreadsheet nobody can act on. You own the data and you still cannot use it.
Ask this on the first call: if we part ways on Friday, what exactly do I have on Monday morning. The answer should include native Seller Central campaigns, an export of historical performance, editable creative files, and a written handover document. If the answer is "a full export from our platform", ask whether anyone outside their team has ever picked it up and run with it.
