Two consoles, two different jobs. Vendor Central makes you a supplier to Amazon, so the work is purchase orders, deductions, and content control. Seller Central keeps you the merchant, so the work is pricing, inventory, and advertising. Hire against the console you actually operate, and score any candidate on both if you run both.
The short version
- The console decides the job description. A great 3P operator is not automatically useful inside a 1P relationship.
- In 1P you give up price control. Amazon owns the retail price, so your levers move to content, catalog accuracy, and negotiation.
- In 3P you own everything and carry everything. Pricing, stock, customer contact, and the whole advertising account.
- Hybrid brands need one team, not two vendors. Split ownership of one catalog produces conflicting listings and duplicate spend.
- Ask for two advertising numbers, not one. The target at launch and the target at maturity, plus the trigger that moves between them.
Why the two consoles need different operators
Start with the mechanism, because it explains every difference in the service you should be buying.
Under Vendor Central you are a wholesaler. Amazon issues purchase orders, takes ownership of the stock, and sets the price it sells at. Your profit is decided months earlier in a terms negotiation, and your operational day is filled with purchase order acceptance, shipment compliance, deductions, and chargebacks. Growth work is real but narrow: better content, cleaner catalog data, accurate item setup, and advertising bought against a price you do not control.
Under Seller Central you are the merchant. You set price, you own inventory risk, you handle the customer, and you keep the full advertising account. Nothing happens unless you do it, which is exhausting and also the reason most brands with ambition end up here. Every lever that moves profit is in your hands rather than in a buyer's.
A manager who has only ever run one of these will apply that console's playbook to the other. In 1P that looks like recommending a price change nobody can make. In 3P it looks like treating advertising as a content problem.
Score a management partner out of 100
Weight the criteria, score each candidate, and keep the sheet. Anyone above 75 is worth a second call.
| Criterion | Weight | What full marks looks like |
|---|---|---|
| Console fit | 20 | Names the console they are strongest in, and says plainly where they are weaker |
| Advertising by stage | 20 | Gives a launch target and a maturity target, and the trigger between them |
| Catalog control | 15 | Explains parentage, variations, and identifier hygiene without being asked |
| Capacity | 15 | States how many accounts the assigned manager carries today |
| Reporting cadence | 10 | A written update weekly, a live review at least twice a month |
| Exit terms | 10 | Short notice, you keep the account and the assets, written handover |
| Access model | 10 | Works inside your account under permissions you can revoke |
The advertising row carries the most weight for a reason. It is the only criterion where a vague answer proves the person has never actually held the account.
The advertising answer that separates them
Ask what advertising cost of sale they target, then refuse the single number. There is no correct ACoS for a brand, only a correct ACoS for a product at a given stage. A launch is buying rank, review velocity, and data, so the efficient number is deliberately bad. A mature product with earned organic position should be run for profit, and the same target that was right at launch is now waste.
So the question has three parts: what do you target at launch, what do you target at maturity, and what specifically moves a product from the first to the second. Anyone who answers with one blanket percentage runs one playbook across every account they touch, and your catalog will be fitted to it.
This is the discipline behind the way we operate at Flapen. Around 50 operators run about 70 brands, and each product carries its own stage and its own number rather than a house-wide target.
What most agencies will not tell you
Most brands do not choose 1P on economics. They get invited, treat the invitation as a promotion, and discover afterwards that they have traded price control and advertising flexibility for a purchase order they cannot forecast. It is a real business model with real advantages, particularly on volume and on shelf stability, but it should be a decision with a spreadsheet behind it rather than a status upgrade.
The second thing: agencies rarely volunteer which console they are actually good at, because the answer narrows their pipeline. We work inside our clients' own Seller Central accounts through granted user permissions that can be revoked at any moment, and that is where our operators are strongest. If your business is 1P-first, ask any candidate, including us, to show what they own in that world before you sign anything.
