Amazon 1P vs 3P Explained: The 2026 Reseller's Guide to Picking a Selling Model

Choosing between Amazon 1P and 3P is one of the biggest calls a seller makes. Get it wrong and you hand your margin to Amazon for years.

By the end of this guide, you'll know which model fits your business, the real fees and margins on each side, and exactly what to do if Amazon just terminated your 1P vendor account.

We'll cover what 1P and 3P actually mean, the 2026 market shift every brand should know about, a 5-question decision framework, and how to actually win on 3P once you're there.

Here's the quick version: Amazon 1P means you sell wholesale to Amazon and Amazon sells to consumers. Amazon 3P means you sell directly to consumers on the Amazon marketplace. 3P gives you more control over pricing, margins, and branding, but you manage marketing, logistics, and customer service yourself. 1P is invitation-only.

Now let's break down what most guides miss.

What Is Amazon 1P vs 3P? (Quick Definitions)

Amazon 1P is a first-party relationship. You sell your products wholesale to Amazon, and Amazon becomes the retailer. Amazon sets the retail price, ships to customers, and handles returns. You fulfill purchase orders and ship inventory to Amazon's warehouses.

Amazon 3P is a third-party relationship. You sell directly to consumers on the amazon marketplace through the Seller Central portal. You set prices, manage listings, and pick your own fulfillment path.

Here's who sells what:

• 1P (Vendor Central): Invitation-only. Amazon buys your inventory wholesale, sets the retail price, ships to customers, and handles returns.
• 3P (Seller Central): Open registration. You list products, set prices, choose FBM or FBA, and handle (or outsource) customer service.

Why does this distinction matter? It decides who owns your margin, your brand, and your daily operations for the next several years. Those stakes are why most sellers revisit the 1P vs 3P choice every 12 to 18 months.

Amazon 1P (Vendor Central): How It Works

In a first-party setup, Amazon assumes control once you ship the purchase order. They own the inventory, they set the price, and they handle the consumer.

Quick answer: Amazon 1P sellers ship wholesale inventory to Amazon based on purchase orders, and Amazon resells it under the "Sold by Amazon" badge. Vendors get Prime eligibility, hands-off logistics, and consolidated fees. They also give up pricing control, real-time data, and listing ownership. It's invitation-only through Vendor Central.

The Pros of Selling 1P on Amazon

• POs on autopilot. Amazon sends purchase orders on a regular cadence. You don't need inventory forecasting tools because Amazon tells you what to ship.
• Prime trust. 1P products are automatically eligible for Prime shipping and carry the "Sold by Amazon" badge, which lifts conversion on shopper trust alone.
• Hands-off logistics. Amazon handles all picking, packing, shipping, and customer service once the inventory lands in their warehouses.
• Consolidated fees. One fee structure replaces 3P's stack of referral, fulfillment, and storage fees.
• Lower inventory risk. Once Amazon takes the PO, the inventory risk shifts to them.

The Cons of Selling 1P on Amazon

• You lose price control. Amazon sets the retail price and can undercut your minimum advertised price policy, which breaks MAP enforcement for your other channels.
• Amazon edits your listings. Product descriptions, images, and A+ content can change without your approval.
• Limited data. 1P vendors rely on delayed Amazon reports instead of real-time dashboards.
• 30 to 90 day payment terms. Cash flow sits tighter than 3P's 14-day settlement window.
• Margin compression. You're selling at the wholesale price to Amazon, not capturing retail margin.

For most brands, 1P works best when Amazon is a small slice of total revenue and you'd rather outsource the operational lift than chase every extra margin point. For wholesale sellers on Amazon who want control, it rarely pencils out.

Amazon 3P (Seller Central): How It Works

Third-party sellers run the storefront themselves. You list the product, price it, and sell directly to consumers on the amazon marketplace. Access is open through Seller Central.

Quick answer: Amazon 3P sellers list products under their own brand or reseller account, set their own prices, and choose FBM (Fulfillment by Merchant) or FBA (Fulfillment by Amazon). They retain margin, pricing control, and listing ownership. They also take on marketing, logistics, and customer service. Registration is open to businesses of all sizes.

The Pros of Selling 3P on Amazon

• Retain control over retail prices. Adjust prices to stay competitive and keep consistency across branded items, or lean on dynamic repricing to do it automatically.
• Total autonomy over product listings. Edit listings, images, and promotions without waiting for Amazon approval.
• Maintain control of brand. Your marketing communications stay consistent with your off-Amazon voice.
• Higher margins. You capture retail margin instead of wholesale margin.
• Faster product launches. No vendor manager approval bottleneck to clear before going live.
• Choice of logistics. Pick FBM or FBA per SKU based on size, weight, and velocity.

How Brand Registry Changes for 3P Sellers

If you own your brand, enroll in Amazon's brand registry once you start selling 3P. It protects listings against hijackers and unlocks A+ Content, Stores, and Brand Analytics. 1P vendors get parts of this automatically, but 3P brand registry hands you real day-to-day brand presence controls that registry sellers actually use.

The Cons of Selling 3P on Amazon

• You run marketing. Listing optimization, Sponsored Products, Sponsored Brands, and Amazon PPC for sellers all sit on your desk.
• You manage logistics. Inventory forecasting, restock alerts, and inventory risk belong to you.
• Customer service is yours. Unless you're on FBA, returns and buyer messages are a daily workload.
• Marketplace fees stack up. Referral fees, FBA fulfillment, monthly storage, long-term storage, and additional fees per violation compound fast.

The tradeoff is real: you capture more upside and take on more execution. Complete control cuts both ways.

The 2026 Shift: Why 1P Is Shrinking and 3P Is Dominating

Third-party selling isn't the fringe option anymore. It's the mainline.

Quick answer: In Q4 2024, third-party sellers accounted for 62% of paid units on Amazon's marketplace, the highest share ever recorded. Amazon's revenue from third-party seller services hit approximately $140 billion in 2023, up roughly $22 billion year-over-year. Meanwhile, Amazon has been terminating smaller 1P vendor accounts, pushing more brands to 3P as their primary Amazon strategy.

The numbers tell the story. 62% of paid units went through third party sellers in Q4 2024. That's not a blip, that's a structural trend.

Revenue follows volume. Amazon's third-party seller services pulled in roughly $140 billion in 2023, up about $22 billion year-over-year. For Amazon, 3P is the growth engine.

Recent strategic shifts by Amazon have sped up the migration. Starting in late 2024, Amazon sent "collaboration terminated" letters to thousands of 1P vendors, primarily those generating under $5 to $10 million in annual sales. Industry coverage reports Amazon is consolidating Vendor Central around its highest-volume brands and pushing smaller vendors out to 3P.

If you're a mid-size brand or a reseller still operating on 1P, the direction of travel is clear. If Amazon hasn't started that conversation with you yet, they may soon. Plan for 3P as the default sales channels strategy.

How Amazon Business (B2B) Fits Into 1P vs 3P

Amazon Business is Amazon's B2B marketplace, and it's open to both 1P and 3P sellers. Third-party sellers can enable Business pricing, quantity discounts, and tax-exempt sales from inside Seller Central. 1P vendors sell into Amazon Business indirectly through their wholesale relationship. For most resellers, Business is a bolt-on to the core 3P strategy, not a reason to stay on 1P.

Ecommerce Operations: What Each Model Demands Day-to-Day

Your daily workload looks completely different on each side. Here's the operational split:

• Inventory management: On 1P, Amazon sends POs and you ship. No forecasting needed. On 3P, you forecast using predictive analytics for seasonal demand and Amazon-specific fulfillment requirements. FBA also adds storage tier limits and Amazon's IPI score to manage.
• Listings and content: On 1P, Amazon can edit product descriptions and images without your approval. On 3P, you own product listings end-to-end and changes go live in minutes.
• Pricing: On 1P, Amazon sets retail. On 3P, you set retail and compete for the Buy Box through automated or manual repricing.
• Advertising: On 1P, you run campaigns through the Amazon Ads console (the platform formerly known as AMS) and often lean on agency support. On 3P, you get full Sponsored Products, Sponsored Brands, and Sponsored Display access inside Seller Central.
• Customer service: On 1P, Amazon owns returns, refunds, and buyer messages. On 3P, those belong to you unless you're using FBA.

The pattern is simple: 1P trades margin for a hands-off operation. 3P trades daily workload for margin and control. Your selling options depend on which tradeoff fits your team's bandwidth and your amazon strategy.

1P vs 3P: Fees, Margins, and Profit Compared

Quick answer: On 1P, Amazon buys at wholesale (usually 40% to 60% of retail) and then assesses chargebacks, co-op fees, and damage allowances that chip away at your realized margin. On 3P, you pay a referral fee (typically 15%), an FBA fulfillment fee per unit, monthly storage, and additional fees for removals or long-term storage. 3P profit margins are higher on paper, but more volatile.

1P fees look simpler on paper, but the hidden costs eat into margin fast.

The 1P fee stack:

• Chargebacks. Penalties for shipping errors, packaging violations, or ASIN issues.
• Co-op fees. A percentage of sales paid back to Amazon for "marketing support."
• Damage allowance. Amazon deducts for damaged units before paying you.
• Effective realized margin. Typically 40% to 60% of retail at the wholesale price, before chargebacks.

The 3P fee stack:

• Referral fees. Usually 15% of the item price, though the rate varies by category.
• FBA fulfillment fee. Per unit, scales with size and weight.
• Monthly storage. Around $0.78 per cubic foot for standard-size items, rising during Q4 peak.
• Aged inventory surcharge. Kicks in at 181 days for standard SKUs.
• Additional fees. Removal orders, disposal, relabeling, and long-term storage.

Here's a concrete example on a $50 retail SKU:

• 1P math. Amazon buys at $25 wholesale. After chargebacks and co-op (~5%), realized revenue is about $22 before your COGS.
• 3P math. You sell at $50. Pay $7.50 referral, ~$5.50 FBA fulfillment, ~$1 storage. You keep about $36 before COGS.

3P leaves more dollars on the table for you, assuming you actually win the sale. Protecting that margin over time is what a healthy Amazon FBA profit margin strategy is built around.

How to Become an Amazon Seller (1P or 3P)

One model you apply for. The other finds you.

Becoming a 1P Vendor

You need a direct invitation from Amazon. There's no application form. Amazon's Vendor Manager team reaches out to established brands with strong off-Amazon sales, differentiated products, or a category they want to own. Once invited, you get access to Vendor Central.

If you haven't been invited, you're not going to become 1P by asking. Focus on growing on 3P first.

Becoming a 3P Seller

Registration is open at sell.amazon.com:

• 1. Create a seller central account and provide business info, tax ID, and bank details.
• 2. Verify your identity (Amazon uses video verification for most new sellers).
• 3. Pick a plan. Individual is $0.99 per sale, Professional is $39.99 per month.
• 4. Once approved, create listings and choose FBM (you ship) or FBA (Amazon ships) per SKU.

The whole process takes anywhere from a few days to a few weeks, depending on verification speed.

Amazon 1P vs 3P: Which Model Is Right for Your Business?

Quick answer: Run through five questions: Who owns the brand? What's your Amazon volume? Can you run marketing and logistics? How much pricing control do you need? How much margin can you absorb giving away? Most resellers land on 3P. Very large established brands that want hands-off execution can justify 1P. Mid-size brands sometimes run a hybrid approach.

Use this 5-question framework:

• 1. Who owns the brand? If you own it, 3P favors control. If you distribute others' brands, 3P is realistically your only option.
• 2. What's your Amazon volume? Under $5M annual, go 3P. Between $5M and $50M, 3P or hybrid. $50M+ with an established brand, 1P is possible, but verify Amazon's 2025 vendor retention posture before you commit.
• 3. Can you run marketing and logistics? No, and you don't want to, 1P's hands-off setup wins. Yes, 3P captures the margin.
• 4. How much pricing control do you need? If MAP enforcement matters for your other channels, 3P. If you don't care about retail price discipline, 1P works.
• 5. How much margin can you give up? Need 40%+ to cover operations and growth, 3P. Can absorb 15% to 25% for hands-off, 1P is fine.

Best Fit for 1P

• Large CPG brands with $50M+ in Amazon sales
• Established direct-import wholesale suppliers
• Brands prioritizing hands-off execution over margin capture
• Brands where Amazon is a small percentage of total revenue

Best Fit for 3P

• Private label sellers who need full brand control
• Wholesale resellers, online arbitrage sellers, and retail arbitrage sellers
• Brands under $50M in Amazon sales, especially those recently terminated from 1P
• Any operator who wants real-time data and pricing control

Hybrid: Running 1P and 3P Together

A hybrid approach means you ship some SKUs to Amazon on 1P (typically high-volume, low-margin commodity items) while running 3P for margin SKUs, exclusives, and new launches. It's common for mid-size brands that still have a 1P relationship they don't want to lose but need 3P's control for the rest of the catalog.

Winning on Amazon 3P: Why Buy Box and Repricing Matter

Control over pricing means nothing if you don't win the Buy Box.

More than 80% of Amazon sales flow through the Buy Box. That "you control the price" benefit of 3P only converts into revenue when your listing is the featured offer at the moment a shopper hits Buy Now. Lose the Buy Box, and your perfectly priced listing collects zero orders.

Manual repricing doesn't scale past 20 to 30 SKUs. Competitors reprice in seconds. You'd be chasing them all day and still losing Buy Box share to whoever automated first. Winning the Buy Box consistently takes software.

Why Artificial Intelligence Repricing Became Table Stakes

Modern repricers use artificial intelligence and machine learning to model competitor behavior, forecast Buy Box rotation, and set prices that maximize margin instead of racing to the bottom. AI pricing reads 20+ Buy Box signals (seller rating, fulfillment type, inventory age, competitor price velocity) and adjusts within seconds.

For any amazon seller managing more than a few dozen ASINs, AI repricing isn't optional. Aura is an AI-powered Amazon repricer built for 3P sellers: wholesale, arbitrage, and private label. It automatically adjusts your price to recapture the Featured Offer when a competitor undercuts you, without racing to the floor.

The Final Verdict on Amazon 1P vs 3P

For most resellers in 2026, 3P wins.

3P wins because of the direction of travel (Amazon is shrinking 1P), margin capture, pricing control, listing control, and real-time data access. Third party sellers now account for the majority of Amazon's paid units, and that share keeps growing.

1P still wins for very large, established brands that want to outsource operations and can absorb margin compression without blinking.

Hybrid is real for mid-size brands. Some SKUs run 1P, others run 3P, and the mix changes as categories mature.

If you're going 3P, your Buy Box share is the metric that matters. Start your free Aura trial and let AI pricing protect your 1p and 3p margin automatically.
