Get more orders by selling on Amazon—that's the plan! Adding Amazon to your multichannel ecommerce mix helps you get more eyes on your products through Amazon’s massive marketplace.
As a new Amazon seller, you need to understand the best way to work with Amazon and meet your business objectives. This includes how to get listed (and avoid getting de-listed), stay compliant, and turn Amazon into a successful sales channel for your products. First, let’s look at the problems new Amazon sellers typically face so you know what to avoid.
Common problems when selling on Amazon
Any time you start selling on a new channel, unexpected problems can arise. That’s why it’s important to look at common problems with selling on Amazon ahead of time so you can be as prepared as possible. Let’s talk about what often gets in the way of success for new Amazon sellers.
Can’t meet program SLAs or requirements

When you start selling on Amazon, sometimes order volume grows so rapidly that it outpaces your ecommerce logistics setup and results in costly overtime, mis-ships, and late orders. The tools and processes that worked when your business was smaller may not be scalable if you experience rapid growth or spikes in order volume.
For example, imagine you normally ship 20 orders per day, print shipping labels out of your front office inkjet printer, and visually scan the shelves for products to fill the paper pick list in your hand. How would you keep up with 3x, 5x, or 10x order volume as your business grows? It’s important to have the foundation for scalable operations laid ahead of time so you can handle rapid growth when it occurs.
Getting de-listed as a Prime Seller
Becoming enrolled in Seller-Fulfilled Prime (SFP) carries the potential for rapid growth in order volume. STAYING an enrolled SFP seller requires an efficient way to keep up with throughput and satisfy Amazon’s requirements, even when your sales skyrocket.
According to Amazon, to keep from getting de-listed, enrolled Amazon Prime sellers must consistently meet the following criteria to maintain their status:
- Provide free 1-day and 2-day delivery for Prime customers
- Give all customers free nationwide standard shipping
- Meet minimum 1-day and 2-day delivery speeds according to Prime customer detail page views
- Achieve an on-time delivery rate of at least 93.5%
- Show a valid tracking rate of at least 99%
- Keep a seller-initiated cancellation rate of less than 0.5%
- Ship and deliver Prime orders on weekends (Saturday, Sunday, or both)
- Offer free returns on items weighing less than fifty pounds
- Allow Amazon to manage all post-order customer service inquiries
Failure to meet the requirements would result in being de-listed as a Prime seller and no longer allowed to use Prime branding1.
Other software doesn’t sync with Amazon
To succeed as an Amazon seller and avoid getting de-listed, you have to keep Amazon updated with accurate tracking information and available inventory. If your other software, such as a shipping solution or your ecommerce platform, doesn’t automatically sync with Amazon, you will get stuck updating Amazon manually. This is not sustainable as order volume grows because it’s a slow and error-prone process.
You need software that connects to Amazon via an API so it can sync, write back tracking information, and update your Amazon marketplace as multichannel fulfillment occurs.
I keep overselling my inventory
Multichannel sales bring a high level of complexity to inventory management. If you don’t have a way to update available inventory on all platforms at the same time, you risk overselling. Manually updating inventory in real-time for multiple sales channels is nearly impossible, and many ecommerce businesses keep overselling their inventory until they have an inventory management system in place.
Takes too long updating catalogs and listings
Managing your catalog and listings for one sales channel is hard enough. Add Amazon to the mix, and suddenly you have double the number of listings to maintain. Depending on how many SKUs you list and how often you update them, it could be a full-time job to keep everything current! You have a million other things to do, and you need an easier way to update your catalogs and listings one time, then have it automatically sync to all sales channels.
The best way to handle this is catalog and channel management software. It works like a central hub for all your channels and listings so you can keep your Amazon listings (and everything else) current without spending so much time.
How to sell on Amazon

There are two main ways to start selling on Amazon: Amazon Seller Central and Amazon Vendor Central. Which is the right one for you? Let's look at the difference between these options.
What is Amazon Seller Central vs. Amazon Vendor Central?
Amazon Seller Central is a way to enter the Amazon marketplace and become a reputable third-party seller, selling your products and building your brand. In contrast, with Amazon Vendor Central you are a supplier for Amazon and sell to them in bulk. Then, Amazon sells the products under the Amazon brand.
Amazon Seller Central is best for D2C brands already selling to end consumers. It’s the easiest and simplest way to start selling on Amazon, and if you are successful, Amazon may want to bring you on as a vendor later. The real question is, do you want to be a supplier FOR Amazon or a seller ON Amazon with your own brand?
To keep things from getting too confusing, we will just focus on Amazon Seller Central for the remainder of this article. If you want to sell on Amazon with your own brand, keep reading.
Becoming an Amazon seller
The good news is, it’s pretty easy to start selling on Amazon by signing up on Amazon Seller Central. Of course, Amazon can change the process at its discretion, so please check the Amazon website for the most up-to-date information. As of the date of this publication, you basically just need to sign up, list a product, promote your product, and fulfill the orders.
It’s important to note that HOW you do these four things will determine whether you succeed as an Amazon seller. There’s nothing wrong with dipping your toe in the water before you fully jump in. However, even when testing a new sales channel, you need a good plan if you want to succeed.
5 steps to success as an Amazon seller

Before you dive into the Amazon marketplace and start listing products, you need to have a warehouse and shipping strategy in place and a plan for how you will fulfill your orders on time. Otherwise, you’ll be struggling, trying to keep your head above water when you become successful. How can you build that momentum on the new sales channel without drowning in order volume?
Here are the five most important steps to becoming a successful Amazon seller:
- Warehouse strategy – Decide whether to fulfill your orders from your own warehouse, a 3PL, or a mix of both.
- Shipping strategy – Choose appropriate shipping software and carriers to control costs and meet Amazon’s valid tracking rate requirements.
- List your products – Start a free Amazon Seller Central account, list your products on Amazon, and consider registering for Seller Fulfilled Prime.
- Fulfill your orders – Use your warehouse and shipping strategy to fulfill your orders accurately and on time to avoid getting de-listed.
- Monitor and adjust – Regularly monitor customer reviews, operational costs, warehouse KPIs, and other data to make strategic adjustments.
How to fulfill Amazon orders

Amazon sellers have five main options when deciding how to fulfill Amazon orders:
- Amazon Warehousing and Distribution (AWD) – Amazon warehouses and distributes your products to the Amazon store and other distribution channels
- Fulfillment by Amazon (FBA) – Amazon warehouses your inventory and fulfill your Amazon orders, functioning as a 3PL
- Amazon Fulfilled by Merchant (FBM) – Use Amazon software with your own warehouse and workers to fulfill your Amazon orders
- Non-Amazon 3PL – A 3PL other than Amazon warehouses your inventory and fulfills your multichannel orders
- Multichannel software with Amazon Partner API – Integrates with all your sales channels to fulfill multichannel orders with your own warehouse and workers
What is Amazon AWD?
Amazon Warehousing and Distribution (AWD) is a low-cost inventory storage and distribution solution, offered by Amazon, that warehouses your products and distributes them to the Amazon store and your other distribution channels. It’s essentially a third-party logistics (3PL) program providing long-term, upstream bulk inventory storage in Prime-ready fulfillment centers 2.
Pros
- The pricing also covers FBA inbound placement with no separate charge
- AWD's auto-replenishment feature keeps your FBA inventory in stock
- Bypass Fulfillment by Amazon (FBA) storage limits to warehouse more goods
- Multichannel distribution is available, so you can use one inventory for all channels
- Time to market: inventory is received/visible 2-4 days after its arrival to AWD, and it’s received by FBA 10-14 days after you request replenishment.
Cons
- Less inventory control and flexibility for businesses that also do B2C/D2C
- May be a slower replenishment method for FBA compared to distributing goods yourself or through a different 3PL
Best for sellers who:
- Want to lower the cost of doing FBA
- Are willing to replenish FBA inventory a bit slower
What is Amazon FBA?
Fulfillment by Amazon (FBA) is the easiest way to sell on Amazon without having to fulfill your own orders. Amazon warehouses your inventory, provides free, 2-day Prime shipping to your customers, handles returns and customer service, and picks, packs, and ships all your orders. Think of it as an all-Amazon 3PL that handles everything for you3.
Pros
- New Seller incentives
- Don’t have to manage fulfillment, returns, or customer service
- No worries about getting de-listed as a Prime seller
- More time to focus on other aspects of your business
Cons
- May be more expensive than handling these activities yourself
- Not recommended for heavy, bulky, or temperature-sensitive products
- Additional fees for aged inventory, returns, removal, disposal, and liquidation
- Less inventory control and flexibility for multichannel sellers
Best for sellers who:
- Want to sell on Amazon but don’t want to warehouse goods or be responsible for fulfilling orders
- Are willing to make less profit if it means avoiding complexity and risk
- Want to expand into other markets quickly without needing to open their own warehouse and develop their own localized storefront
What is Amazon FBM?
Amazon Fulfilled by Merchant (FBM) is a suite of Amazon software solutions to help you fulfill orders from your own warehouse instead of having Amazon warehouses hold your inventory and fulfill your orders.
Amazon FBM includes tools for inventory management, shipping, and returns management, and you can use it alongside Fulfillment by Amazon (FBA) according to your business strategy4.
Pros
- Can fulfill heavy, bulky, or temperature-sensitive products that FBA can't do
- May be more cost-effective than FBA or other 3PLs
- Manage your inventory more effectively for multichannel fulfillment
Cons
- Does not include warehouse management system capabilities
- No direct API integration to NetSuite (requires a connector)
- Gives Amazon access to your order info and data for all sales channels
Best for sellers who:
- Sell on multiple channels and warehouse their own inventory
- Operate a small warehouse and don’t experience seasonal peaks or high growth
- Don’t require warehouse management system features/capabilities
When to use a non-Amazon 3PL to fulfill orders?
While it may seem counterintuitive to use a non-Amazon 3PL to fulfill Amazon orders, there are certain situations where it makes sense for multichannel sellers:
- You want to house all your inventory in one place for greater agility, but you don’t want to operate your own warehouse.
- Your products are heavy, bulky, temperature-sensitive, or otherwise not eligible for Fulfillment by Amazon, and you don’t want to use your own warehouse.
- The non-Amazon 3PL meets Prime Seller requirements and is more cost-effective for your business than FBA.
- You want to avoid certain rules and restrictions related to FBA.
- You sell on Amazon but are not a Prime Seller and don’t need to meet Prime Seller requirements.
Why use multichannel ecommerce logistics software with an Amazon Selling Partner API?
Many multichannel sellers prefer a purpose-built solution when it comes to ecommerce logistics software. Unlike the one-size-fits-all Amazon FBA or FBM options, and unlike a non-Amazon 3PL that handles fulfillment for you, multichannel software with an Amazon Selling Partner API provides a highly customizable set of capabilities to solve your unique problems AND the common problems most Amazon sellers face.
Multichannel ecommerce logistics software includes best-in-class:
- Shipping software
- Inventory management system (IMS)
- Order management system (OMS)
- Warehouse management system (WMS)
- Catalog management system
- Multichannel listing management software
- Purchasing and purchase order management software
- Returns management software
- Enterprise resource planning (ERP) software
For multichannel sellers, Amazon is only one piece of the puzzle, and logistics for all the other sales channels require a great deal of connectivity to keep everything running smoothly. In this case, it makes sense to use a purpose-built set of integrated software solutions that sync with Amazon via API.
By reducing the complexity of multichannel order fulfillment, this type of solution helps ecommerce businesses manage hyper-growth while continuing to expand their catalogs, listings, and sales channels for a strong, diverse business model.
How to ship Amazon orders to customers

Now that you understand the multichannel order fulfillment options, let’s talk about shipping. There are five general ways to ship Amazon orders to customers:
- Fulfillment by Amazon (FBA) - Amazon fulfills and ships your orders
- Amazon Buy Shipping – Amazon's multi-carrier program to print discounted labels
- Amazon Shipping – Amazon's carrier service to deliver parcels with Amazon’s fleet
- Veeqo by Amazon – Amazon's multichannel shipping software platform
- Third-party shipping software with Amazon Partner API – Integrated with Amazon
We already discussed Fulfillment by Amazon earlier, so we will not revisit it here. Before we dive into the pros and cons of the other methods, we should take a quick look at Seller Fulfilled Prime shipping since it has changed in recent years.
Seller Fulfilled Prime shipping
Amazon used to require all enrolled Prime Sellers to use Amazon Buy Shipping or Amazon Shipping, but that requirement is no longer listed on their Seller Fulfilled Prime page as of the date of this publication.
While Amazon has not explicitly stated that Prime Sellers are no longer required to use these shipping methods (and likely prefers everyone to continue to use them), we have found no Amazon-official statement saying you have to. Please be sure to review Amazon’s Seller Fulfilled Prime delivery performance requirements when planning your shipping strategy.
What is Amazon Buy Shipping?
Amazon Buy Shipping is a multi-carrier program offered by Amazon to print shipping labels for Amazon orders. You can access it through Amazon Seller Central, Veeqo, API, or third-party shipping software integrations. With Amazon Buy Shipping, you get access to pre-negotiated discount shipping rates with UPS, Amazon Shipping (Amazon’s delivery fleet), FedEx, USPS, and other major carriers5.
Pros
- Amazon guarantees 1-2-day delivery to ensure you meet Prime Seller requirements
- “A-to-z Guarantee” covering customer claims without hurting your default rate
- Available within Seller Central (helpful if you already use that platform frequently)
Cons
- Bulk label printing only "up to 100 labels”
- May not support certain carriers and services
- Cannot print labels for your other sales channels from Amazon Seller Central
Best for sellers who:
- Primarily ship Amazon orders and want the “A-to-z Guarantee”
- Don’t want to negotiate discounts with carriers
- Prefer Amazon’s discounted rates over other discounted rate programs
What is Amazon Shipping carrier service?
Amazon Shipping is a shipping carrier service available through Amazon Seller Central and a few select multichannel, multi-carrier shipping software partners, including Descartes ShipRush and Veeqo. It allows both Amazon sellers and non-Amazon sellers to use Amazon’s shipping fleet to deliver packages, just like USPS, UPS, or FedEx6.
Pros
- Pickup and delivery 7 days a week
- No residential fees or weekend delivery charges
- “A-to-z Guarantee” covering customer claims without hurting your default rate
Cons
- Not available through all third-party shipping software platforms
- May not offer the cheapest shipping rates
- Does not offer international shipping services
Best for sellers who:
- Frequently ship Amazon orders and want the “A-to-z Guarantee” for those shipments
- Need pickup and delivery services 7 days a week
What is Veeqo by Amazon?
Veeqo is an Amazon company offering free multichannel shipping software with Amazon’s pre-negotiated discount shipping rates for multiple carriers. This program includes some inventory management capabilities, data analytics and reporting, business automation, and light warehouse management features for pick and pack7.
Pros
- Integrates with Amazon Shipping, Amazon Buy Shipping, and other Amazon programs
- Multichannel data analytics for FBA, FBM, and other channels
- “A-to-z Guarantee” covering customer claims without hurting your default rate
Cons
- May not support all carriers and services, especially regional carriers
- Does not offer direct integrations for NetSuite or any other ERP, IMS/OMS, or WMS
- Amazon may gain access to all the data for all your other sales channels
Best for sellers who:
- Prefer to use all Amazon-owned products/solutions
- Operate a small warehouse and do not need robust warehouse management system features/functionality
- Do not experience seasonal peaks or rapid business growth
Why use third-party multi-carrier shipping software with an Amazon Selling Partner API?
Even though Amazon offers plenty of seller-fulfilled shipping options, many multichannel sellers still opt for third-party, multi-carrier shipping software connected to Amazon with a Selling Partner API. Here are some situations where this option makes sense:
You want to print shipping labels for NetSuite.
Amazon’s shipping software is not available as a SuiteApp. To connect any of the Amazon options to NetSuite and print shipping labels, you must use a connector. In contrast, some third-party shipping software such as Descartes ShipRush for NetSuite and ShipStation for NetSuite are “Built for Oracle NetSuite” SuiteApps and come with strong NetSuite partnerships for optimal performance.
You want shipping software fully integrated with your WMS.
Veeqo by Amazon does not include third-party warehouse management systems in its list of integrations as of the date of this publication, though it does include SnapFulfil as a 3PL option with a third-party integration. If you want a seamless WMS + shipping software integration, you would be better off using third-party shipping software (with an Amazon Selling Partner API) that already fully integrates with your preferred WMS.
You don’t want all your eggs in Amazon’s basket.
Didn’t Business 101 teach us to diversify, diversify, diversify? Anytime you place too many of your critical business operations in one company’s hands, you expose yourself to risk. As much as we love Amazon, do we really want them to have all our data from all sales channels, all shipping operations, and our entire multichannel inventory? In light of recent anti-trust lawsuits against big tech, it’s important to think about diversification.
You don’t like the features or functionality of Amazon’s options.
You have unique business needs and preferences when it comes to technology. If Amazon’s shipping software doesn’t work the way you need it to, it’s time to look at third-party options. Just make sure your third-party shipping platform includes an Amazon Selling Partner API, otherwise you will face extreme challenges with meeting the valid tracking rate requirements and syncing with Amazon.
You love your existing program, and Amazon doesn’t integrate with it.
This is a tough one: to bail on a beloved ecommerce logistics program? You’ve already invested years in learning how this software works, and you built a successful business with it. You really don’t want to switch just to start shipping Amazon orders. Even though Amazon shipping software may not integrate with your favorite platform, many third-party shipping solutions offer a wider variety of integrations AND connect to Amazon’s API.
You need more robust features than Amazon’s shipping software provides.
Depending on the complexity and scale of your business, you may need more powerful shipping software with a more robust feature set. Some third-party shipping platforms offer purpose-built feature sets for specific use cases, along with customization to meet unique business needs. As long as the program uses the Amazon Selling Partner API, you can import and ship Amazon orders while still getting the other features you need.
