Amazon Fba Vs Fbm

If you want to sell on Amazon, one of the first choices you must make is this: should you use Amazon FBA or Amazon FBM?

This is a big decision because it affects your costs, time, profit margins, shipping process, and customer experience. Some sellers love FBA because Amazon handles storage and shipping. Others prefer FBM Amazon because it gives them more control and can be cheaper for certain products.

In this guide, we’ll break down Amazon FBA vs FBM in simple terms. We’ll also cover fees, shipping requirements, Reddit-style seller opinions, what to avoid selling, whether you need an LLC, and how to compare the numbers with an Amazon FBA vs FBM calculator.

What Is the Difference Between Amazon FBM and FBA?

Let’s start with the basics.

Amazon FBA stands for Fulfillment by Amazon. With FBA, you send your products to Amazon’s warehouses. Amazon stores your inventory, packs orders, ships them to customers, handles customer service for delivery issues, and processes many returns.

Amazon FBM stands for Fulfillment by Merchant. With FBM, you keep your products yourself or in your own warehouse or third-party warehouse. When a customer places an order, you pack and ship it.

Here is the simplest way to think about it:

FBA = Amazon stores and ships your products

FBM = You store and ship your products

Both methods let you sell on Amazon’s marketplace, but the work and costs are very different.

You can learn more about Amazon fulfillment options on Amazon’s own seller pages at Amazon Seller Central and Fulfillment by Amazon.

FBM Amazon: How It Works

With FBM Amazon, you list your products on Amazon and manage most of the fulfillment yourself. This means you are responsible for:

• Storing inventory
• Packing orders
• Shipping on time
• Uploading tracking
• Handling customer questions
• Managing returns
• Meeting Amazon performance standards

FBM is often a good fit for sellers who:

• Already have a warehouse
• Sell oversized or heavy products
• Have slow-moving inventory
• Want more control over branding and packaging
• Want to avoid FBA storage fees

Some sellers also use a mix of both models. For example, they send fast-selling items to FBA and keep oversized or seasonal products under FBM.

Amazon FBA vs FBM Fees

Fees are one of the biggest factors when choosing FBA vs FBM.

Amazon FBA fees

With FBA, sellers usually pay:

• Referral fee
• Fulfillment fee
• Monthly storage fee
• Aged inventory surcharge for old stock
• Optional prep or labeling fees

The referral fee is usually a percentage of the sale price and applies to both FBA and FBM. Amazon’s referral fee category details are listed at Amazon Seller Fees.

The fulfillment fee covers picking, packing, shipping, customer service, and return handling for many items.

Monthly storage fees depend on how much space your inventory takes up in Amazon’s warehouses. If your products sit too long, aged inventory fees can add up fast.

Amazon FBM fees

Amazon FBM fees are usually simpler. Sellers often pay:

• Referral fee
• Monthly Professional selling plan fee if applicable
• Shipping costs
• Packaging materials
• Storage costs on their own side
• Labor costs if they have staff

So the direct Amazon FBM fees may look lower, but your own shipping and labor costs matter a lot.

Simple fee comparison formula

A basic way to compare FBA and FBM is:

Profit with FBA = Sale price - product cost - referral fee - FBA fulfillment fee - storage fee - inbound shipping to Amazon

Profit with FBM = Sale price - product cost - referral fee - shipping cost - packaging cost - labor cost - storage cost

This is why many sellers use an Amazon FBA vs FBM calculator before deciding.

Amazon FBA vs FBM Calculator: How to Compare Profit

An Amazon FBA vs FBM calculator helps you estimate which model leaves you with more money.

You can use Amazon’s own tools, such as the Amazon Revenue Calculator, if you have access to Seller Central, or third-party calculators online.

When using a calculator, include:

• Product selling price
• Cost of goods
• Product size and weight
• Amazon referral fee
• FBA fee
• FBM shipping cost
• Packaging cost
• Storage cost
• Return rate
• Prep cost
• Inbound freight to Amazon for FBA

A common mistake is only looking at Amazon’s fees and ignoring hidden FBM costs like labor, supplies, and storage. Another mistake is ignoring long-term storage risk with FBA.

The best choice depends on your product.

FBA vs FBM Pros and Cons

There is no single winner for every seller. Here are the main FBA vs FBM pros and cons.

Pros of Amazon FBA

• Prime eligibility can improve conversions

Amazon FBM Shipping Requirements

Amazon FBM shipping requirements are strict because Amazon wants buyers to get a good experience, even when sellers ship the products themselves.

FBM sellers generally need to:

• Ship orders on time
• Upload valid tracking
• Deliver within the promised time window
• Keep cancellation rates low
• Keep late shipment rates low
• Maintain good account health

You can review Amazon’s policies through Seller Central help pages and related account health resources.

If you want to qualify for Prime while using your own fulfillment, Amazon also has Seller Fulfilled Prime, though it has tough performance standards.

For FBM, your shipping setup should include:

• Reliable carriers
• Strong packaging
• Inventory accuracy
• Fast order processing
• Tracking number upload automation

This is where inventory and order management software can help a lot.

Do I Need an LLC to Sell on Amazon FBM?

No, you do not always need an LLC to sell on Amazon FBM.

You can start selling as a sole proprietor in many cases. Amazon does not require every seller to form an LLC before opening a seller account.

That said, an LLC can be helpful for several reasons:

• It may offer personal liability protection
• It can make your business look more professional
• It may help with taxes and banking separation
• It can make it easier to grow later

Whether you need one depends on your risk level, business goals, and local laws. It is smart to speak with a CPA or business attorney before deciding.

You can also review small business structure basics at the U.S. Small Business Administration.

So the short answer is:

No, an LLC is not required for Amazon FBM

Yes, an LLC may still be a smart move

What to Avoid Selling on Amazon

A lot of new sellers ask what to avoid selling on Amazon. This is a smart question, because not every product is worth listing.

Here are some common types to avoid, especially when you are just starting:

Restricted or gated products

Some categories and brands require approval. If you list these without understanding the rules, you can get blocked or even suspended. Review Amazon category rules at Product Category and Listing Restrictions.

Counterfeit-risk items

Luxury brands, branded electronics, and trendy items with lots of fake versions are risky. Amazon is very strict on authenticity.

Hazardous materials

Some beauty, chemical, battery, and aerosol products have hazmat rules. These can be hard for beginners.

Very low-margin products

If your item only makes a few dollars before fees, FBA and ad costs can wipe out profits.

Oversized heavy products

These can work under FBM, but they are often expensive under FBA because fulfillment and storage fees rise with size and weight.

Fragile products

Glass, ceramics, and easy-to-break items can lead to more returns and bad reviews.

Seasonal products without a plan

Holiday items can sell fast, but leftover inventory can become expensive with FBA storage fees.

Products with intense competition

If dozens of sellers already compete on the same listing, profit may be hard to keep.

A better approach is to look for products with steady demand, moderate competition, healthy margins, and simple fulfillment needs.

How Many Amazon Sellers Make Over $100k?

Many people want to know how many Amazon sellers make over $100k. The truth is that some do very well, but not everyone reaches that level.

Industry surveys from companies like Jungle Scout often show that a meaningful share of Amazon sellers exceed $100,000 in annual sales, though sales are not the same as profit. Some reports have found that around a significant minority of sellers cross the $100k mark in yearly revenue.

But there are two important things to remember:

Revenue is not profit

Bigger sales often mean bigger costs

A seller with $100k in annual sales might still have thin margins if fees, ads, and returns are high.

So yes, many Amazon sellers make over $100k in revenue, but far fewer make $100k in actual profit.

Amazon FBA vs FBM Reddit: What Real Sellers Often Say

If you search “Amazon FBA vs FBM Reddit,” you’ll find a wide range of opinions on communities like Reddit, especially in ecommerce and Amazon seller threads.

Here are common themes sellers often mention:

What Reddit users like about FBA

• Easier to scale
• Better conversion due to Prime
• Less time spent packing orders
• Great for private label and standard-size products

What Reddit users complain about with FBM

• More manual work

The main lesson from Reddit discussions is simple: your product type matters more than general advice. A heavy item may do better under FBM. A fast-moving, small item may do better under FBA.

Amazon FBA vs Dropshipping

Another common comparison is Amazon FBA vs dropshipping.

With Amazon FBA, you buy inventory upfront and send it to Amazon. Amazon stores and ships it.

With dropshipping, you list products for sale without holding the inventory yourself. When a customer orders, a supplier ships the product.

Amazon has strict rules for dropshipping. You must always be the seller of record, and your supplier cannot appear to be the seller. You can review the policy at Amazon Dropshipping Policy.

FBA vs dropshipping: key differences

• FBA gives more control over customer experience
• Dropshipping requires less upfront inventory investment
• FBA usually offers faster shipping
• Dropshipping often has lower margins and more stock problems
• FBA is usually better for building a long-term brand

For many serious sellers, FBA or FBM is more stable than pure dropshipping on Amazon.

Which Is Better for Different Types of Sellers?

Here is a simple way to decide.

FBA may be better if you:

• Sell small, lightweight products
• Want Prime benefits
• Have products with steady demand
• Want to scale fast
• Do not want to manage daily shipping

FBM may be better if you:

• Sell large or heavy items
• Already have fulfillment space
• Want more control
• Have slow-moving products
• Need custom packaging or bundles
• Want to avoid FBA storage fees

Use both if you:

• Sell different product types
• Want to test demand
• Need flexibility during peak seasons
• Want backup fulfillment options

Many successful sellers do not choose only one. They use a hybrid model.

Final Thoughts on Amazon FBA vs FBM

When comparing Amazon FBA vs FBM, the best option depends on your products, margins, operations, and goals.

FBA is easier to scale and often better for conversion, especially with Prime. But it can become expensive if your products are slow-moving, bulky, or low-margin.

FBM gives you more control and can reduce some Amazon fees, but it requires stronger operations and reliable shipping.

Before choosing, run the numbers with an Amazon FBA vs FBM calculator, study your product size and margins, and think honestly about how much fulfillment work you can handle.

If you plan to sell across Amazon, Shopify, and other channels, using strong inventory software can make a huge difference. Ordoro is a great inventory management software, and it has several hundreds of happy Shopify merchants using Ordoro. For sellers who need better inventory visibility and order management, it is a smart tool to consider.
