Vendor Central vs Seller Central (1P vs 3P)

Vendor Central and Seller Central are the two ways a brand can be on Amazon, and they are different businesses wearing the same storefront. On Seller Central (3P, third party) you are the retailer: you set the price, own the inventory, and keep the retail margin. On Vendor Central (1P, first party) you are a wholesale supplier: Amazon sends purchase orders, sets the retail price, and resells your product as "Ships from and Sold by Amazon."

Most brands do not get to agonize over this choice. Seller Central is open to anyone; Vendor Central is invite-only, and in 2026 Amazon is actively shrinking who gets to stay. The real question has shifted from "which model should we choose" to "which of our products belong in each model, and is our 1P margin still what we think it is."

What is the actual difference between 1P and 3P?

The model determines who sells to the customer and, with it, every lever you control. On 3P you are the merchant of record; on 1P Amazon is. Everything else follows from that:

Two rows in that table do most of the deciding. Payment terms: a 14-day settlement versus net 30 to 90 is a working-capital question that sinks otherwise healthy 1P economics for smaller brands. And net margin: on the same SKU, 3P commonly keeps in the range of $9 to $10 more per unit than 1P, because wholesale pricing to Amazon typically runs 45 to 65 percent off retail before co-op and chargeback deductions take their share.

Which model makes more money?

For most brands under roughly $50M in Amazon revenue, 3P delivers more net profit per unit, commonly 2 to 3 times more, because you keep retail margin and control price. 1P wins on volume mechanics instead: Amazon's purchase orders, its supply chain in categories it invests in (grocery, CPG, consumables), and the conversion lift of the "Sold by Amazon" badge.

The 1P number that surprises finance teams is not the wholesale discount; it is what comes off after it. Co-op allowances (marketing, freight, damage) often run 5 to 15 percent of invoice value, and compliance chargebacks stack on top of that. We wrote a full breakdown of where that money goes in Amazon deductions explained.

As a former Senior Vendor Manager in challenger categories, my role focused on identifying and recruiting brands that appeared to be strong fits for 1P relationships. The one thing that regularly surprised 3P vendors that converted to 1P was the impact being shipped and sold by Amazon had on conversion. The first thing most shoppers do when searching on Amazon is click the filters for 4-star-and-better reviews and Prime. Being a 1P vendor means your inventory always gets Prime badging, and categories are measured on what percentage of your product traffic is considered Retail Fast Track (the on-detail-page messaging of "purchase in X amount of time, receive by Y date"), so the category teams are always optimizing for it... even when you can't get your VM on the phone.

There is also still a population of Amazon shoppers who will only purchase items shipped and sold by Amazon, either due to the trust Amazon has built via their great customer service and strong pricing, or because they've been burned by a purchase from a 3P seller previously. As a 1P vendor your experience is going to be highly dependent on your internal Amazon category team, the category your SKUs sit within, and your size relative to competitors within the space on Amazon. That being said, even today I would still select 1P over 3P when given the choice: the per-unit margin math above is real, but the conversion mechanics (Prime badging and Fast Track on every unit, the shipped-and-sold-by-Amazon buyer population) and the supply-chain programs available only to 1P vendors are advantages 3P cannot buy at any fee level.

Why is Amazon shrinking Vendor Central?

Since late 2024, Amazon has been terminating Vendor Central relationships with sub-enterprise brands, roughly those generating under $5M to $10M a year, and pushing them to the 3P marketplace. What remains on 1P in 2026 skews to enterprise scale ($20M+ preferred, $5M+ as a practical floor), categories where Amazon's supply chain adds real efficiency, and vendors that can meet increasingly strict EDI, ASN, and PO On-Time Accuracy demands.

The consequence for anyone still on 1P: the compliance bar keeps rising. Vendors are reporting a material increase in ASN, prep, and PO on-time chargebacks in 2026, with fewer disputes resolving in the vendor's favor. Brands that modeled their 1P margin on 2024 chargeback rates are finding themselves 2 to 4 points light on contribution margin, which is exactly the leakage a margin recovery audit is built to quantify.

When does 1P still make sense?

Choose 1P when the volume mechanics genuinely apply to you: Amazon is actively issuing POs at enterprise scale, your category benefits from Amazon's supply-chain investment, the "Sold by Amazon" badge measurably lifts conversion in your niche, and your operations can hold strict EDI and PO-accuracy compliance without bleeding chargebacks.

Choose 3P when you want pricing and promotional control, you are launching new SKUs, cash flow matters (14 days versus 90 is not a rounding error), or you are anywhere below enterprise scale. 3P also gives you direct MAP enforcement; on 1P, Amazon's pricing algorithm will match a rogue discounter and erode your price floor without asking.

Should you run a hybrid?

For brands with mixed catalogs, hybrid is increasingly the norm, and the decision unit is the ASIN, not the account. Amazon has historically had a love-hate relationship with hybrid accounts: at times enforcing that manufacturers only use a single channel via programs like Amazon Standards for Brands, and at others encouraging vendors to list profitability-challenged selection on 3P via a hybrid strategy. Enforcement can change at the discretion of particular categories or even vendor managers. If a category team does try to implement enforcement actions due to your hybrid strategy, it is possible to negotiate a final resolution with them with proper planning and preparation.

A working framework:

1. Hero ASINs with strong 1P economics stay 1P: high velocity, categories where the Amazon badge converts, terms you have actually negotiated.
2. Long-tail, bulky, and margin-sensitive SKUs go 3P: you keep retail margin and pricing control where Amazon's scale adds least.
3. Review quarterly against real margin data, not list assumptions: co-op percentages, chargeback rates, and freight terms drift every year, usually against you.
4. Keep a 3P transition plan even if you are happily 1P. Vendor Central is invite-only and increasingly fragile; Amazon can stop issuing POs without notice, and 1P inventory in Amazon's network does not automatically become your FBA stock.

The margin question underneath the model question

Whichever model you run, the profitability answer lives in the deduction and fee detail, not the headline margin. 1P brands leak through chargebacks, shortage claims, and co-op overbilling, much of it recoverable inside Amazon's dispute windows; 3P brands leak through FBA fee errors and lost reimbursements instead. The model choice sets which leaks you have, not whether you have them.

If you run a 1P or hybrid brand and have not audited your deduction lines in the last year, that is the fastest margin conversation we can have. The Margin Recovery Audit quantifies what leaked, what is recoverable inside the dispute windows, and what to fix so it stops. It starts with a free scan of your data.
