Lock-in is structural, not contractual. Open the Seller Central account in your own entity, grant the agency revocable user permissions, and keep campaigns and creative source files where you can reach them. Get those three right and a long contract cannot trap you. Get them wrong and a short one will not save you.
The short version
- Own the account. Your entity, your credentials, their permissions.
- Revocable access. You remove them yourself, without asking.
- Campaigns live in your account, not inside the agency's tooling.
- Creative source files, not exports. Layered files, not flattened JPEGs.
- Contract length matters least. It is the fourth line of defense, not the first.
The four kinds of lock-in
I have watched all four from both sides, running Flapen with about 70 brands and previously buying agency services at BRANDED and Moonshot Brands.
| Type | How it happens | How bad | Fix |
|---|---|---|---|
| Account | Agency created or holds the seller account | Severe | Open your own before you hire |
| Asset | Creative and campaign history live in their systems | High | Specify storage and source files |
| Knowledge | Nobody documented why anything is set up as it is | High | Require written rationale |
| Contract | Long term, long notice, auto-renewal | Moderate | Month-to-month, 30 days |
Account lock-in
The worst one, and the easiest to avoid before it happens.
Some agencies offer to set up Seller Central for new sellers. It is convenient, and it makes your business an asset inside their organization. Open the account yourself, in your own legal entity, with your own credentials and bank details. Then grant user permissions.
Done properly, you can see every action taken in your account and you can revoke access at any moment without a conversation. That is how we work, and it is not a favor. It is the only defensible structure.
Asset lock-in
Quieter and more common. Campaigns built inside the agency's own account structure or tooling, creative delivered as flattened exports, keyword research kept in their spreadsheets.
Nobody is being malicious. It is just how work accumulates when nobody specified otherwise. Specify otherwise. Ask where campaigns physically live and ask for creative in editable source files.
Campaign history is the asset people underestimate. It is months of learning about which keywords convert for your product at which bid, bought entirely with your ad budget. Rebuilding it means paying for the same education twice.
Knowledge lock-in
The most invisible. Everything is technically yours, and none of it is explained.
You have a campaign structure with no stated logic, negative keyword lists with no reasoning, and a pricing strategy nobody wrote down. A new agency inherits a machine with no manual and starts by rebuilding, which costs you a quarter.
The fix is a standing requirement rather than an exit clause: the weekly written update should say what changed and why. Do that for a year and the documentation exists by the time you need it.
Contract lock-in
Real, and the least of the four. A twelve-month term with a 90-day notice window is expensive when you want out. It is still recoverable, unlike account lock-in.
Month-to-month with 30 days' notice is achievable. We work that way and clients still stay for years.
How do I keep control while outsourcing
Five checks you can run this week:
- Log in yourself. If you cannot, that is the whole answer.
- Open user permissions. Confirm you can revoke every agency user without help.
- Ask where campaigns live. Your account, or their structure.
- Ask for one creative source file. See if it arrives editable.
- Read last week's update. Does it say what changed and why, or just what happened?
What most agencies will not tell you
The agencies that need lock-in are the ones whose month seven does not justify the fee. Lock-in is a retention mechanism substituting for results, and it is designed before any work is done.
The tell is how the question lands. Ask, during the sales process, exactly what happens if you leave in month two. A confident agency describes the handover in detail and moves on. An agency that needs you tends to explain why leaving would be complicated, or reassures you that clients never want to.
The other quiet one: no lock-in mechanism is required when the alternative is expensive for the client on merit. We take the last month upfront on the first invoice, run month-to-month, and publish the pricing. Retention has to come from the work, which is the correct amount of pressure for a vendor to be under.
