What our 1P to 3P transition covers
Transition plan and timeline
Which ASINs move first, how remaining POs and Amazon’s 1P stock are handled, and when to switch, so sales do not drop out.
Catalog and Brand Registry control
Brand Registry and detail page contribution rights checked, so your Seller Central offers attach to the existing ASINs and keep their reviews.
Pricing and Buy Box
3P prices set from margin and your pricing policy, and the Buy Box watched daily while Amazon sells through remaining 1P inventory.
FBA or own fulfilment set-up
FBA inbound plans, prep and labelling, or Seller Fulfilled Prime from your own warehouse, set up before the switch.
Ads and reporting moved
Amazon Ads rebuilt in Seller Central with the same keywords and learnings, and reporting moved from vendor to seller data.

Why brands move from Vendor Central to Seller Central
Vendor Central is simple when purchase orders are steady: Amazon buys wholesale and handles everything after that. But many vendors see POs become less predictable, margins squeezed by co-op, allowances, chargebacks and shortage deductions, and retail prices set by Amazon in ways that clash with other retailers. Seller Central gives the brand control of pricing, inventory and customer data, at the cost of running more of the operation. For some brands a hybrid, with some ASINs on 1P and others on 3P, works best. We help you decide with numbers, not guesswork. For the basics, see Vendor Central vs Seller Central.
Protecting sales during the switch
The risky part is the overlap. Amazon may keep selling 1P stock it has already bought, sometimes at a different price, while your 3P offers start on the same ASINs. If this is not planned, the Buy Box moves around, ads point at offers you do not control, and sales dip. We time the switch around remaining POs, keep your detail pages under your Brand Registry control, make sure FBA stock is in place before Amazon’s runs out and watch the Buy Box every day.
Running Seller Central well from day one
On 3P, the brand owns account health, inventory planning, fees and ads. The same in-house team that plans the move then runs Amazon account management, inventory and Amazon Ads in Seller Central. If you are staying on 1P for now, see our Amazon Vendor Central management. We cover every Amazon marketplace, including the US, the UK, Canada and Europe.

Frequently asked questions
Is there an agency that helps brands switch from Vendor Central to Seller Central?
Yes. CommerceKind plans and runs 1P to 3P transitions: a product-level margin model, a staged timeline around remaining POs, Brand Registry and catalog control, 3P pricing, FBA set-up, ads moved to Seller Central and daily Buy Box monitoring during the switch.
Should my brand switch from Vendor Central to Seller Central?
It depends on your margins, catalog and team. Seller Central gives you pricing control and customer data but you run more of the operation. We model 1P and 3P margins product by product and recommend 1P, 3P or a hybrid.
What is the difference between Amazon 1P and 3P?
1P (Vendor Central) means Amazon buys your products wholesale and resells them, setting the retail price. 3P (Seller Central) means you sell directly to shoppers on Amazon, set your own prices and manage inventory, fees and account health.
Will we lose our reviews and rankings when we move to 3P?
Usually not. Seller Central offers attach to the same ASINs, so reviews and sales history stay on the detail page. Rankings can move during the overlap, which is why we plan the timing and watch the Buy Box closely.
What happens to Amazon’s remaining 1P stock?
Amazon may continue to sell inventory it has already bought. We plan the switch around remaining POs and Amazon’s stock levels so your 3P offers are ready when its stock runs down.
Can we run a hybrid 1P and 3P model?
Yes. Many brands keep some ASINs on Vendor Central and sell others through Seller Central. We plan which products sit where so 1P and 3P offers do not compete on the same ASIN.
How long does a 1P to 3P transition take?
Most transitions are planned over a few months, depending on your catalog, remaining POs and how quickly FBA stock can be built. We share a timeline after reviewing your account.
Do you also manage Vendor Central?
Yes. We manage Vendor Central for brands that stay on 1P, including purchase orders, chargebacks, shortage claims, content and Amazon Ads.
Can my agency white-label a 1P to 3P transition?
Yes. We plan and run the transition under your agency’s brand, with an NDA and non-solicit first, through our white-label Amazon Vendor Central service.
