What is Amazon FBA?

When an ecommerce company makes the decision of selling on Amazon, there’s the option to use the Amazon FBA system (the acronym of Fulfillment By Amazon which by the way, negates the need for the extra Amazon term).

How does Amazon FBA work?

If you are thinking of becoming an Amazon seller, Amazon fulfilment works in the majority of cases like this.

  1. Register for Amazon.
  2. Create your Amazon listings and select ‘FBA’ as the fulfilment option.
  3. Create an FBA shipment order.
  4. Ship your products to Amazon for storage in a fulfilment centre- there are many around the UK and Europe. For more information, check out .

Note that Amazon automatically assigns which FBA you must ship to when you create an FBA shipment.

  1. After shipping to Amazon, you’re given access to their tracking system software to keep a tab on your inventory.
  2. Once a purchase is made either through Amazon listings or other ecommerce platforms you are linked to, Amazon picks, packages, and ships the item.

FBA is not available just for selling through Amazon.

For example, orders can be fulfilled via their service for products sold via your own website though in most cases, the packaging will show Amazon’s involvement.

Note that this service is called ‘Amazon Multi-channel Fulfillment and its cost is a little higher than that of FBA.

  1. The method of shipping is determined by the buyer and Amazon, and the buyer is provided with a tracking code relevant to their choice.
  2. All customer service and returns are carried out under the Amazon name, as are possible shipment issues.

What’re the Main Advantages of FBA?

Greater Online Presence

As Amazon is a ‘go-to’ site for products, it opens up the opportunity of selling to millions of prospective customers.

Perhaps the most important reason for FBA is access to the Amazon Prime customers, as they are Amazon’s best and yield the highest spend.

A Prime customer pays Amazon an annual fee which allows them free, next-day delivery for any inventory deemed ‘Prime’.

Prime inventory just happens to be almost every FBA product whether Amazon’s or your own.

Being able to access Prime members as customers could double, or even triple your daily sales.

Take a look at this article from to see how Prime membership helps FBA sellers.

Depending on the size of your company, storage is very often an issue, but by selling through FBA as an Amazon business your storage problems are largely overcome.

Delivery Problems Addressed At Source

Shipping problems are addressed via Amazon, as is the 24-hour customer service which is handled in the language of the country it is sold from.

This doesn’t, of course, include addressing issues of poor quality products or negative feedback of the item which has to be remedied by you.

Speed of Delivery

Shipping speed is superior to many other outlets as it’s handled directly by Amazon and Prime

members have the extra advantage of free delivery.

Win the Buy Box

There’s an opportunity to win the ‘buy box’, which is a system Amazon has implemented to entice better quality, and hassle-free sellers pay the extra to gain an advantage over the competitors within their selling platform.

For a better understanding and opportunity to raise the chances of winning the buy box, this blog from explains the concept in greater detail.

Perceived Superior Products

Products on Amazon are generally perceived to be of better quality than through say selling the item yourself as the Amazon branding offers peace of mind for the majority of customers.

If Amazon Breaks Your Item

Accidents happen and you need to know that your products are in good hands. In the event of damage to any of your items, Amazon will reimburse you for the costs.

Payment To You is Regular

Every fortnight, Amazon tallies up sales less fees and pays it directly into your bank account.

You can even request ad-hoc payments in between if you need a cash flow boost

Q: If My Product Falls Under Amazon’s Free Delivery Category, Am I Charged?

A: No. If the customer doesn’t have to pay, neither do you.

Q: How are Fees Deducted on FBA?

A: Fees are taken by Amazon at point of sale from the customer’s payment. The balance is viewable in the ‘Payments’ section under the ‘Reports’ tab in your Amazon sales account.

Q: Are Sellers Charged for Each Item Sold on ‘Sell On Amazon’?

As there’s an advantage to selling on Amazon Marketplaces, each Amazon product is attributed with variable costs associated with their category as a type of referral fee.

However, if the product was not sold through Amazon but sent via FBA, the ‘Selling On Amazon’s fee’ doesn’t apply.

Q: How is FBA Billed?

By a verified and authorised charging credit card every month on the electronic invoice.

Q: How Should Products be Prepared for FBA?

Research your competition

What are they selling and how do they describe their products?

What, in your opinion, is making them sell better than their other competition?

Study Amazon’s own best selling products

How do they sell?

What is the composition of the description (its placement, details, dimensions etc)

Sell with intelligence – think about upselling or bundling products

Remember you’ll be paying for monthly storage so you need products that move quickly, sell well, or bring in greater profits.

Rank your products on how well they are likely to sell (based on product research or previous sales).

If you sell cricket bats, for example, think about bundling it with a ball, stumps and pads.

If you have two similar products and one brings in a higher profit, think about offering the added advantages of buying it instead.

This has an added bonus of making your listing stand out as being unique so you will instantly reduce your competition.

Use a repricing program if you intend to sell seriously

In order to win the buy box, Amazon sellers have to be proactive about their prices and one of doing this is by constantly altering your prices -even hourly.

Many Amazon sellers use these types of tools to be price competitive.

Doing this without the software would be almost impossible so take a look at some of the repricing tools here, and in other areas online.

Utilise AMS

What is AMS?

Amazon provides a marketing tool for its vendors and sellers called ‘Amazon Marketing Services’ in order to create highlighted and targeted advertisements for items of your choice.

In Amazon’s own words;

  • Choose the products you want to advertise.
  • Decide which keywords to target and how much you want to bid for clicks.
  • Get started with a small budget and create an ad in minutes.

For more details about how the tool works, follow this link straight to

Look at ways you can highlight your brand persona

Do everything within your power to analyse and understand your target market.

Only then can you begin to position your brand correctly and stay consistent.

Even your packaging is important as no one likes to receive damaged or poorly designed wrappings.

Employ SEO with your product listing and titles

Along with brand persona, it’s vital to understand how to optimise search engine optimisation in order to give a high ranking customer experience.

The right descriptive sets of keywords can do wonders for sales.

Think about how you describe your products and who uses them and include creative content that plays upon these descriptions.

Amazon allows ‘up to’ 250 characters but don’t overdo it.

It’s more desirable to use this space wisely, adding only what’s needed to help promote your items in their best light.

Optimise your product images

Amazon has precise rules about how images are displayed.

Their latest requirements can be found here.

In any event, don’t just comply with their rules, ensure they are the best you can do.

Think lighting, angles and close-ups and highlight fine details when you can.

Nowadays, 360° photo processing is becoming all the rage and offers a brilliant representation of a product.

The devil’s in the detail

One of the best methods of displaying a product’s details is through bullet point listing.

The more an item is described, the greater the chance of a sale as if you don’t do it, someone else will and they’ll be more likely to win the buy box.

Think dimensions, weight, colour options, uses.

Put yourself in your customer’s shoes and imagine what they are likely to ask you.

Answer as many questions as you can before they’re asked

If your products need a little more explanation than everyday items, ensure you address this with your product details.

Instructional photos and videos help sell products.

You don’t want to be inundated with questions about your products so ensure you create your own question and answer section before they come flooding in.

It’s likely you’ll still be asked things you hadn’t thought of but if they are relevant, add them into the description.

How quickly you answer and the inferred tone of your response all have a bearing upon your sales.

Amazon provides a section for questions and answers but some sellers don’t take advantage of this, leaving customers to ask when others haven’t bothered and bought from a competitor.

Get your colleagues, friends and family to fill in these sections with any questions you or they can think about the product.

The answers you give will give the impression of good customer service.

Don’t be afraid to ask for feedback and reviews.

Buyers are more likely to purchase items that have positive reviews and feedback.

Whenever you make a sale, ask for a review and when and if it arrives to make sure you

thank the buyer, whether via email or on the product listing.

If you’re unsure how to go about getting reviews, take a look at this blog from  and others online.
