In this Zen Arbitrage vs Eflip review, we’ll try to explore both software tools and compare which is a better Amazon book FBA tool between Zen Arbitrage and Eflip in terms of features, price and support.

Here are the topics that we’re going to discuss.

What is Amazon Book FBA?

FBA stands for Fulfillment by Amazon.


With Amazon Book FBA, you can store your products in Amazon’s fulfillment centers, and it gets picked, packed and shipped to the customers. FBA allows Amazon sellers to reach more customers and scale their business.

Sellers who use FBA can offer fast and free shipping to their customers, which opens up the door to targeting Amazon Prime members. This is beneficial for sole traders and for those who are selling from international locations. And with an Amazon Book FBA tool such as Zen Arbitrage, it can provide them with more opportunities and make their decisions much more efficient.

Did you know? About half of all sales on Amazon come from third-party sellers. Out of the top 10,000 sellers, 66% of them use FBA.

For beginners, there are ways to get started selling such as determining products and range, calculating Amazon revenue, creating an FBA shipping plan and more. Fortunately, there are tools such as Zen Arbitrage and eflip for this.

The biggest benefits of FBA on Amazon for the seller are Prime Eligibility, handing off customer service to Amazon and not having to fulfill orders in house.

The fees associated with FBA are your Selling Plan which is $49.99, Referral Fees which are category dependent and between 10 – 17%, Stickering & Labeling ($0.30 per label), Fulfillment Fees & Storage fees (see Amazon FBA Fees section for details).

If you have a Pro Amazon Seller Account through Seller Central, then you can use the Amazon FBA program to sell on Amazon.

Amazon FBA works as your fulfillment channel for Amazon Seller Central Sellers.  You send your inventory into FBA  fulfillment centers around the country and when a customer places an order from your Amazon store, the order is sent to the customer directly by Amazon instead of the merchant (you).  The most notable benefit of Amazon FBA is it makes your products Prime eligible.

Overview: Zen Arbitrage vs Eflip


Zen Arbitrage is a fully web-based online arbitrage software for Amazon FBA sellers developed by Peter Valley. To get started, you will just need an Amazon FBA Seller account then you can quickly start. This tool requires no previous experience selling on Amazon so it’s perfect for those who are looking to get started in Amazon business.

Here’s how Zen Arbitrage works and how you can make profits from selling books on Amazon fast and easy.

Like Zen Arbitrage, Eflip is an Online Arbitrage Software for FBA Sellers created by Caleb Roth. It helps sellers make a profit year-round by purchasing low-priced items and later reselling them for a premium price via FBA.


Eflip is a software specifically designed to search all the sources of information about books on Amazon and which one has the most profitable potential.

Here’s how to source books on Amazon using the Eflip tool.

Features: Zen Arbitrage vs Eflip

Both Eflip and Zen Arbitrage have features that can be incredibly beneficial for Amazon FBA sellers. There may be features that are similar to both tools but there are also some features that are unique to each of them. Now whether which is the one you should use or which one is better depends on how much results you want to get and how fast you want to get there.

Zen Arbitrage Features

Zen Arbitrage has quite a few huge features that Eflip doesn’t have. Here are the top 4 benefits of Zen Arbitrage:

Zen Arbitrage shows FBA offers for 100% of over 20 million tracked books

Zen offers the world’s first textbook database, so FBA sellers can shortcut right to the profit. You can find and sort through millions of books fast with this tool.

Essentially, you will need to analyze hundreds of books at once, and you want to look at the most important factors or data such as the FBA price. Under the Zen Arbitrage results section, you can quickly find the lowest FBA price offer. This makes it easier for you to find profitable books and calculate your profit right away. eFlip also has a similar feature called “Outliers” but it’s on a separate page from the main books database.

Shipping fees

The prices in Zen Arbitrage quickly shows you the shipping costs of the books you will purchase. Unlike Zen Arbitrage, you still need to click over to Amazon to view shipping costs on eFlip. This adds an extra step. With Zen Arbitrage, you don’t have to flip back and forth between the Zen Arbitrage window and the Amazon page since you can find all the necessary info on a single page.

ISBN Marketplace

The Zen Arbitrage Marketplace feature is a book arbitrage buying and selling platform that does a couple of things. This includes selling “leads” of books you can find in the Zen Arbitrage database for sale to other members. You’re not selling the actual book but you’re only letting other members know that you found profitable books they can sell. That way, you can monetize your searches without actually purchasing books.

Another thing is that it allows you to skip past searching and purchase these “leads” from other members for a fraction of their expected net profit. The Marketplace calculates all Amazon fees and shows you an estimated net profit before you purchase.

Database size

This is the ultimate advantage or feature that Zen Arbitrage has over other Amazon book FBA tools. It shows more search results of profitable books than eFlip. eFlip has only 10% of Zen’s results for a random search.


There are also certain features that make Zen Arbitrage the true winner including Keepa charts, sales and profit tracking tool and more.

Keepa Charts

When you hover over any price or sales rank value on Zen Arbitrage, a box will show up displaying the six-month historical price or sales rank graph from Keepa. This useful feature is important to review price history charts, price drop alerts, price watches and daily drops. It’s an essential tool for anyone that wants to sell through their site. 

Sales and Profit Tracking Tool

Zen Arbitrage has a simple, built-in inventory and sales tracking tool. When you buy a book, you can add it to your sales tracking page where it displays profits (and automatically subtracts all Amazon fees). This awesome tool is ideal for those who want to track profits closely.

Beginner’s View

Zen Arbitrage has a cool toggle switch that lets you switch between a “Streamlined” view for beginners, reducing the data on the screen to the bare minimum; and an “Enhanced” view – adding four additional columns of data, like trade-in values. This feature makes it easier for users to use the Zen Arbitrage software, especially for beginners.

Restricted Book Check

There’s no exact formula that can help decide which textbooks are restricted and which aren’t. However, Amazon has put up some guidelines on restricting textbooks. 

  • Textbooks from 3 publishers are restricted.
  • Moderate to high-demand textbooks (better than 500,000 on average) are restricted.

Automated scan of 30 other sites

Zen Arbitrage scans over 30 other bookselling sites – without clicking. Just hover over the Bookfinder.com icon and a popup window appears showing the lowest priced copy on the Internet across 30 other bookselling sites.


Eflip Features

Multiple product categories

There’s only one advantage of eFlip over Zen Arbitrage. For example, its multiple product categories allow you to find other categories outside of books, such as vinyl or CDs.

If you want to focus on books, then Zen Arbitrage is a perfect tool for that. However, if you want to diversify your outside of books, this is where eFlip wins over Zen Arbitrage. Vinyl tends to be very niche and something more suitable for eBay. This is because most buyers are looking for close-up images showing condition, and the CD market when you are buying from a 3rd party merchant to flip on Amazon FBA – is saturated with product and very slim (or no) profit margins. Also, access to Vinyl, CD, and DVD categories means you’ll be charged extra accordingly (above eFlip’s $79/month charge for access to its main book arbitrage tool).

Like Zen Arbitrage, eFlip also gives you key analysis tools such as Keepa graph, sales history and pricing calculator.

Pricing Calculator

The pricing calculator is a useful feature that allows you to check potential profit depending on your Buy price and sell price. This tool makes it easier to figure out whether the profit from a book will be worth the effort of buying, processing, and repricing the book once it’s in Amazon’s warehouse.

Keepa Graph

Another awesome feature that is similar to both tools is the Keepa graph which allows you to figure out if a book is worth researching further or not.  Like Zen Arbitrage, Eflip also has the same feature of Keepa graph showing the sales history in the search results page.

Support: Zen Arbitrage vs Eflip

Both Eflip and Zen Arbitrage have features that can be incredibly beneficial for Amazon FBA sellers. There may be features that are similar to both tools but there are also some features that are unique to each of them. Now whether which is the one you should use or which one is better in Zen Arbitrage vs Eflip depends on how much results you want to get and how fast you want to get there.

Zen Arbitrage Support

Text Support

Zen Arbitrage offers text message support from Peter Valley himself. There’s also a free trial where you can email the team. They also offer live monthly training with Peter Valley where he teaches some aspect of the business and answers questions without extra charge.

Built-in Chat Support

Unlike Zen’s variety of support channels, eFlip doesn’t provide much support to the users.

Price: Zen Arbitrage vs Eflip

There may be features that are similar to both tools but there are also some features that are unique to each of them.

Expert Tips for Selling Amazon FBA books

Selling books on Amazon is a great way to make good income or even start building an Amazon business. If you’re really serious about how selling on Amazon works, as well as where and how to find the best book sales, here are 5 few helpful expert tips to sell Amazon FBA books better.

Research competitors to find profitable books

Start by looking at Amazon’s best sellers rank. Using the Zen Arbitrage tool, you can find all the necessary info like estimated monthly sales, competitor info, pricing and fee calculators.

Be smart about what books you sell

Always consider the sales rank. Products with high ranking mean it sells fast, but also remember that there is competition. Although high ranking products have the best profit potential, try also looking at the low ranking books and see which one you can possibly profit from (with less competition). Understanding sales rank can help you keep track of the competition.

Start small

It’s much easier if you can start with just a handful of books. You can create an organized process and see which works and which doesn’t and eventually add more books as you grow.

Establish a good branding

If you want to stand out from the competition, you need to have a unique brand. Understand your target customers and create consistency in how you sell your books. Make sure your brand personality stands out upon delivery to keep customers coming back.

Apply good SEO practices

Amazon is a huge marketplace. With thousands of products, it can be quite difficult to stand out from the competition. Using the right keywords, for example, can help your customers find your products. Optimized book titles and descriptions also get higher ranks in the search results.

Amazon’s FBA program allows any business, regardless of the niche or size, to reach out to wide customers and take advantage of one of the largest selling platforms in the world. Whether you’re an experienced marketer or looking to start a passive income, selling books on Amazon is definitely a profitable business to invest into. Having the right tools help you find more opportunities and make things much easier and faster.

Zen Arbitrage vs Eflip: Verdict

Selling books is definitely not a get rich quick method. It can take time to build a sizable inventory of quality products or even find a way to sell books fast. Fortunately, there are tools such as Eflip and Zen Arbitrage to help you make it much easier. 

Again, having the necessary information and tool is one way to make things much easier if you are really serious and you want to have a successful Amazon business. This applies to other businesses as well, regardless of the niche.

If you are looking for a better Amazon book FBA tool between Zen Arbitrage vs Eflip, Zen Arbitrage is a better choice. Zen has more essential features that Eflip doesn’t have. And if there are any good features that Eflip have, most of them perhaps were pioneered by Zen Arbitrage. And in business generally, the more key features a tool has, the more profit potential you will get.

While Eflip started as a clone of Zen Arbitrage, it seems it hasn’t progressed. Eflip is just trying to catch up with Zen Arbitrage but it still remains to be excellent by many when it comes to the Amazon Book FBA tool.

Which is the better Amazon book FBA tool? In terms of features, Zen Arbitrage is a true winner here. You won’t find a better software for sourcing profitable books on Amazon than Zen Arbitrage.
