Best Amazon Seller Tools in 2021

Selling on Amazon may be a lucrative business, but success is guaranteed only if you’re willing to invest time learning the ropes and working hard at maintaining your inventory and product listings.

Fortunately, Amazon sellers today are in a much better position than those who started a decade ago. Technological advances and Amazon’s steady growth into a global retail giant resulted in a thriving community of third-party providers offering business support.

From product research and inventory management to advertising and accounting systems, as they say, there’s an app for that.

However, many software vendors package their services in a misleading manner. So, sellers have no choice but to go through a trial-and-error process, trying out one app after another until they hit the jackpot.

We know. We’ve been there, done that. And our journey has led us to curate a list of reliable providers that effectively support every aspect of an Amazon business.

If you’re looking for services that will make your life as a seller much simpler, and your road to success much shorter, then this list is for you. Whether you’re just starting out or have been at it for months, you can save a lot of time and money by using these best Amazon Seller tools in 2021.

And for your convenience, we have organized our selection according to the type of services they provide.

Product Research and Scouting

Forget everything you’ve learned at university or from your brick-and-mortar store about researching and scouting for the best products to sell. Amazon has revolutionized the rules of retail selling and in all the good ways possible.


Since you can ship your goods to anywhere in the country, the national population is your target market. And if you allow Amazon to take care of your fulfillment, you can even join its marketplaces in other parts of the world.

In the same manner, your sources are not restricted to local suppliers any more. Importing to Amazon’s warehouses is now an online transaction and shipments can take as short as a couple of weeks.

In this scenario, you need Amazon product hunting tools to determine the right products that appeal to as many Amazon shoppers as possible. Below are our recommendations.



With various ways of searching for products guaranteed to sell on Amazon, ProfitGuru offers the most value for your investment. It is your best tool for wholesale research.

By providing data on the performance of competing products on Amazon based on their respective ASINs, ProfitGuru allows you to glean the potential of your own items to sell on the platform.

This Amazon product research tool is very helpful for newbie sellers. You can use it to find brands in categories where competition is not stiff and whose products are not carried either by the brand owners themselves or by Amazon. Your next step would be to either contact the owners directly and offer to sell their goods or to search for suppliers that already do.

ProfitGuru is already popular among wholesale sellers because it provides supplier information on popular brands. This saves you the effort of going through a vetting process with various vendors.

And for private labeling prospects, the Listing Quality Score of ProfitGuru is extremely beneficial. It helps you spot promising products by comparing the performance of different brands on certain specified parameters. You might be surprised at how many of them achieve high sales despite their average-looking listings.

The most widely used product research tool among professional Amazon sellers, Jungle Scout has developed proprietary Amazon product analysis algorithms that give you a host of information on any product or niche on the platform. These include estimated profitability, consumer demand, the competitive landscape, and even seasonality.

For brand builders focused on private labeling, Jungle Scout can help locate global suppliers and manufactures of top brands. Their facts and figures are reliably harvested from the Customs Import Trade Data.

Jungle Scout boasts a robust suite of other Amazon-specific tools as well, such as Keyword Scout, which helps sellers create listings and PPC campaigns with keywords that make them visible in search results. However, their monthly subscription is not cheap, and many of their features are not very useful.

Probably the second largest suite of tools for Amazon sellers, Helium10 may not be worth the monthly subscription if you intend to use it for product research alone. In fact, the strength of this software lies in its powerful proprietary algorithm for listing optimization.

With the Magnet tool, you can harvest high-volume keywords to optimize your listing and create both automated and manual PPC campaigns. Using the Frankenstein tool, you will be able to rank those keywords according to their relevance to your product.

For product research, Helium10 guides you from the general level of BlackBox where you can scan millions of products through various categories and niches, to the medium level of Trendster which provides demand, seasonality, and sales trends of any product, down to the specific level of X-Ray that shows in-depth information such as pricing and revenue estimates.

Listing Optimization and Product Launch

To ensure sales on the Amazon platform, launching your product and optimizing your listing according to the unique behaviors of the Amazon community is a must. In the past year, the number of Amazon shoppers increased dramatically due to the pandemic that forced people to stay indoors and shop online.

In particular, the Boomers who used to habitually patronize physical stores had no choice but to purchase their essentials and non-essentials on the internet. 


You can consider employing some of these Amazon Seller tools in 2021 that have also evolved with the numerous changes on the Amazon platform.



One of the older Amazon keyword research tools, MerchantWords has been providing sellers with keywords for listing optimization since 2012. Their extensive data are based specifically on Amazon shoppers, not on search engine trends or PPC ads. 

You can use its API, designed for listing advisors and volume sellers, to optimize your listings. In addition, MerchantWords shows you the accurate shopping trends of Amazon visitors through proprietary algorithms created by its Data Science team.

Created by the company SixLeaf, ZonBlast is a tool dedicated to product launches on the Amazon platform through targeted promotions. You can use it to create campaigns, and then leave it alone to manage them and monitor rebates.

Promotions are essentially discounts or giveaways that you offer when launching a product. Ideally, they drive traffic to your listings, and consequently, boost sales. These elements combine to push your listings to page one, making them more visible in search results. This, in turn, increases your organic traffic and sales.

In addition to fully automated promotions, ZonBlast also provides ways to create short URLs for Amazon product pages. Compared to the long URLs assigned by Amazon’s A9 algorithm, shorter ones not only increase brand awareness but also facilitate ease of use by shoppers. 

Cost: $47 per month

ZonJump is another product launch software that helps drive traffic to Amazon product listings. It works on a unique strategy of boosting the ranking of any product on specific keywords. Rather than focusing on the Amazon platform, this tool works on external traffic and redirects it to Amazon listings.

Using highly targeted ads aimed at users of Google and Facebook, among others, ZonJump entices your potential buyers with coupons. However, you should note that your success in using this tool relies heavily on your listing’s optimization.

Cost: Per Coupon Pricing

Ecomdash Listing Tool


For Amazon sellers who focus on bulk listings, EcomDash provides a way to launch multiple products with speed and accuracy. The bulk upload feature of its Bulk Listing tool has the ability to format multiple listings simultaneously. You can then conveniently export them to Amazon.

Even if your products are listed under different categories, EcomDash can still list them quickly using its Multi-Channel Listing tool. And you don’t have to worry about info errors.

Keep in mind that this software is essentially a tool for managing bulk listings. It doesn’t optimize them, nor does it create or manage ad campaigns for product launches. This means you would need to engage the services of another vendor for these purposes.

However, EcomDash also offers inventory management for multiple online marketplaces and web stores, including Shopify, eBay, and WooCommerce. They can sync all your inventory across the board, including variations and bundled items.

And since we’re already on the topic of inventory management, let’s hop on to the options available on the market today.

Inventory Management

Among the existing Amazon Seller tools in 2021 dedicated to inventory management, we tried out a lot. 


Sadly, none of the tools we tested were anything that is close to good. It seems that most of these tools are built by non-Amazon sellers because they are not intuitive to sellers’ needs. And while a few do understand Amazon, they either still lack some features or are poorly made.

With that said, we found two (the best in the lot) which could help you manage your inventory:



If you’re running a wholesale Amazon business, RestockPro is the best available tool for managing your inventory. It keeps your inventory up to date through real-time tracking of inbound and outbound shipments.

The software also assists you with timely reorders to ensure that your products will not go out of stock. This is crucial for your sales because the moment your product becomes unavailable on the Amazon platform, it loses its ranking, and it might take time to recover.

Reorders to your suppliers can be done on RestockPro as well. You can use their template or create a customized reorder form. The tool automatically checks the information you’ve entered for accuracy and then ensures the on-time arrival of your shipments.

All of the above are ideal scenarios. In reality, when we used RestockPro for our wholesale business on Amazon, we found it expensive for the below-average rate of our experience. Their interface is outdated, the software was slow, and they often went down due to technical issues. Plus, it did not support bundling from different suppliers, and it didn’t integrate with other marketplaces either. 

Cost: from $99.99 per month

Forcastly is a predictive software that has the ability to forecast product demand accurately and just within seconds.

If you are a private label Amazon seller using FBA, then Forcastly is the inventory management tool that suits your needs. It works well for stocks shipped directly from suppliers to Amazon’s warehouses.

But when we tested it on large amounts of products, we were not satisfied with its performance, particularly the laborious updating of the numbers. Also, it does not support bundles and kits.

On the positive side, this software was acquired by JungleScout, which tells you that its services are reliable.

Cost: from $80 per month

Advertising and PPC

The uniqueness of the Amazon marketplace extends to marketing and advertising. Simply put, what works in all other e-commerce stores, and even in search engines like Google, wouldn’t fly on the Amazon platform.


This determines the visibility and ranking of each product in every category and niche. Therefore, promoting your products to Amazon shoppers needs the expertise provided by apps built around this algorithm.

These are the top four software we found to do the job efficiently:

Seller Labs


The Seller Labs software helps Amazon sellers automate ad campaigns with its smart PPC algorithm. Using the Ignite tool, you get to enjoy PPC management on autopilot while optimizing your campaigns and maximizing your ad spend.

Seller Labs also offers other services to support an Amazon FBA business, including a keyword research tool and an automated buyer-seller messaging tool.

Automated Pricing

Unlike Walmart, which controls pricing and favors the lowest rates within its physical and online stores, Amazon encourages its sellers to dictate their own prices.


Thus, in order to stay price-competitive, you need to employ Amazon Seller tools in 2021 that are able to automate your product pricing based on your business rules. Doing so also saves you the time and effort which you can divert to growing your enterprise instead.

You can study the apps below and choose the one that best fits your business model.



The Repricing Central tool of Bqool is an automated Amazon seller analytics software solution that you can use to win the Amazon Buy Box. At the same time, it guarantees the accuracy of a product’s prices and maintains healthy profit margins with the Profit Calculator feature, which factors in all fees and costs.

We tried using RepriceIT and found that while it works for both small Amazon businesses and large-scale sellers, it also lacks some essential features like filtering options. However, it’s the best choice in terms of monthly cost, and they offer a free trial as well.

Accounting and Tax

Yes, even online merchants are subject to taxes. The good news is that, as an Amazon seller, you don’t need to hire an in-house accountant to take care of your finances. You got it – there’s an app for that.

Keep in mind, though, that you still need a CPA come tax time to look through your books and journals, and to ensure your numbers are balanced. However, you can cut down on accountant fees if you use any of the accounting software below right at the start of the year.
