The best Amazon arbitrage software, tools and apps (2026)

What is Amazon online arbitrage?

Online arbitrage is buying products from online retailers at a lower price and selling them on Amazon for profit. Retail arbitrage is the same idea in physical stores. Both are popular ways to make money on Amazon without creating your own products, and with the right software you find deals faster and grow more efficiently. New to the model? Start with what Amazon arbitrage is and how it works.

Why you need software for Amazon online arbitrage

Finding profitable products manually takes too much time. The right software helps you:

• Find deals quickly
• Calculate profits accurately
• Check if you're allowed to sell certain products
• Track prices and inventory
• Manage your listings efficiently

The essential tools for Amazon online arbitrage success

Here are the must-have tools that will make your online arbitrage business more profitable:

Keepa - the price history tracker

Keepa is a basic tool every Amazon seller needs. The browser extension has a free tier, and Keepa Pro (€29 a month since early 2026, up from €19) unlocks the full history and seller data. It shows you:

• How prices changed over time
• How quickly products sell (sales rank history)
• Who's selling the product (Amazon or third-party sellers)
• Who's getting the Buy Box
• How many sellers are competing

Keepa helps you predict if a product will be profitable based on its history. For example, you might notice that certain products sell better and at higher prices during holidays.

Stealth Seller - the storefront tracker that really works

Stealth Seller is one of the best tools for serious Amazon arbitrage sellers. This software gives you a big advantage by:

• Tracking competitor storefronts and alerting you when they add new products
• Helping you find profitable products that successful sellers are already making money on
• Sending you notifications so you never miss good opportunities
• Letting you filter by category, buy box status, sales rank, and more
• Making it easy to manage multiple tracked sellers

Stealth Seller basically does the storefront stalking for you that many top sellers use to find good products. Instead of checking competitor stores manually, you get alerts about new listings from sellers you track.

The pricing depends on how many sellers you want to track:

• Basic: Track 50 sellers for $38/month
• Mini Ultra: Track 200 sellers for $98/month
• Ultra: Track 600 sellers for $298/month

Every monthly plan comes with 3 days free, and each tier also includes AI search, the FBA profit calculator, folders and product alerts.

Many successful arbitrage sellers say Stealth Seller is their go-to tool for consistently finding profitable products without spending hours searching.

SellerAmp - the product research tool

SellerAmp (SAS) is a great all-in-one tool starting at $19.95 per month, with a 14-day free trial. It helps with:

• Estimating monthly sales
• Calculating profit margins and ROI
• Setting maximum buying costs for products
• Checking competitor storefronts to find profitable products
• Exporting data to Google Sheets for tracking seasonal opportunities

One of the most valuable features is seeing what successful sellers are already selling. This helps you find brands and products that sell well without guessing.

Tactical Arbitrage - the high-volume scanner

Tactical Arbitrage scans more than 1,400 retailer websites and matches what it finds against Amazon listings, so you can process thousands of products in one run. It's built for volume:

• Bulk scans of retailer categories and search results
• Reverse search from an Amazon product to the stores selling it
• Filters for ROI, sales rank and eligibility

Tactical Arbitrage is now sold only as part of the Seller 365 bundle, from $69 a month, alongside other Amazon seller tools. It's powerful but heavy; if you check one product at a time, SellerAmp or Stealth Seller's calculator is the lighter choice.

Arbitrage Hero - a deal finding option

Arbitrage Hero is another tool some sellers use, billed daily from $1.57 a day (about $47 a month) with a 7-day free trial. It:

• Scans retail websites for potential deals
• Calculates ROI and profits automatically
• Provides links and data for buying decisions

However, many top sellers find they can achieve excellent results just by focusing on the core trio of Stealth Seller, Keepa, and SellerAmp.

ArbiSource - price drops across retailers

ArbiSource scans hundreds of US and UK online retailers and compares their prices against Amazon. Its Price Drops feed surfaces deals as retailers cut prices, and you can run your own retailer or category scans. It integrates with SellerAmp and has a 7-day free trial.

SmartScout - brand and seller research

SmartScout maps Amazon by brand, seller and subcategory, which helps arbitrage sellers spot brands where too many resellers already share the listing. Plans start at around $29 a month and include a Chrome extension with an FBA calculator.

Actorio - online arbitrage for Europe

If you sell on Amazon's European marketplaces, Actorio scans suppliers across Europe and compares them with Amazon UK, Germany, France, Italy, Spain and more, including cross-border flips between marketplaces. It starts at about €79 a month with a 14-day free trial, and is a poor fit if your sales are mostly US.

BQool Repricer - the pricing automation tool

Once you've built up inventory, a repricer is essential. BQool (from $25/month, with a 14-day free trial) automatically adjusts your prices to stay competitive by:

• Monitoring competitor prices every 15 minutes
• Adjusting your prices within your set minimum and maximum
• Helping you get the Buy Box more often
• Saving you hours of manual price checking

A repricer ensures you're not wasting time manually changing prices, allowing you to focus on finding more products to sell.

Free tools that add extra profit

These free tools can help boost your margins:

• Capital One Shopping: Automatically finds coupon codes
• Cash Back Monitor: Finds the best cashback rates for different stores
• GCX (formerly Raise's marketplace): Lets you buy discounted gift cards to use for purchasing inventory

Retail arbitrage apps for scanning in stores

Retail arbitrage happens in the aisle, so the tool that matters is a barcode scanner on your phone that tells you in seconds whether an item is worth buying.

Amazon Seller app - free and essential

Amazon's own Seller app scans any barcode and shows the current offers, fees and whether you're allowed to sell the item. It's free with your seller account, and every retail arbitrage seller should have it installed.

SellerAmp mobile app - full analysis in the aisle

The SellerAmp app (iOS and Android) brings the SAS calculator into the store: scan a barcode and see profit, ROI, eligibility and IP alerts, with a Speed Mode for scanning many items in a row. It comes with your SellerAmp subscription.

ScoutIQ - offline scanning for books and big stores

ScoutIQ is a scanner known for book sourcing. Its Live plan starts at $14 a month; LivePro ($44 a month) adds a downloadable database so scans work with no signal, which helps in big stores with poor reception. The database covers the US and UK, and there's a 14-day free trial.

Online, retail or both: once you've found a product in a store, Stealth Seller's calculator and Chrome extension check the same numbers on the Amazon listing before you buy.

IP Alert - protect your Amazon account

IP Alert, now part of Seller Assistant, helps you avoid intellectual property complaints that could suspend your account. A single lookup is free; it's included in Seller Assistant's paid plans from $29.99 a month. It warns you when a product has potential IP issues, helping you avoid risky listings.

Common questions about Amazon online arbitrage software

Is it worth paying for online arbitrage software?

Yes. While free tools can help you get started, paid software saves so much time that it quickly pays for itself. Even basic tools like Keepa (€29/month) and Stealth Seller ($38/month) can really boost your efficiency and profits. When you bundle these tools together, you create a powerful system for finding and capitalizing on arbitrage opportunities.

What's the minimum investment needed to start?

You can begin with about $90-100 per month for essential software (Keepa Pro + SellerAmp + Stealth Seller Basic), or less on Keepa's free tier, plus your inventory budget. Many successful arbitrage sellers start with just $500-1000 for inventory.

How do I know which products will be profitable?

Good arbitrage software will calculate this for you. Look for products with:

• A healthy ROI (20-50% depending on your strategy)
• Consistent sales history (check Keepa graphs)
• Few competing sellers
• No sales restrictions

Can I do online arbitrage without any software?

Technically yes, but it's really inefficient. Without software, you'll spend hours manually checking prices and sales history, and you'll miss many profitable opportunities.

How do these tools work together?

Each tool handles a different part of your business:

• Keepa helps with research and verification
• Stealth Seller tracks competitor storefronts and alerts you to new opportunities
• SellerAmp helps analyze potential products
• BQool Repricer manages your prices once listed
• Free tools help maximize your margins

The real power comes when you combine these tools. For example, using Stealth Seller to find products, then verifying them with Keepa, and finally managing pricing with BQool creates a seamless workflow.

What about retail arbitrage vs. online arbitrage?

Many of these tools work for both. The main difference is that for retail arbitrage you'll want a scanner app on your phone: the free Amazon Seller app to start, then SellerAmp's mobile app or ScoutIQ once you scan in volume. See the retail arbitrage apps section above.

Getting started: a simple plan

1. Start with Keepa (free, or €29/month for Pro) to understand product history
2. Add Stealth Seller ($38/month) to track successful sellers and get alerts on new products
3. Use SellerAmp ($19.95/month) to analyze and validate potential products
4. Use free tools like Capital One Shopping for extra savings
5. Once you're selling consistently, add a repricer like BQool ($25/month)

Many successful sellers start with just Keepa and Stealth Seller as their core bundle. This powerful combination gives you both historical data and real-time opportunities.

Final thoughts

Online arbitrage on Amazon can be really profitable with the right approach and tools. Start with the basics like Keepa and Stealth Seller, add more tools as you grow, and focus on finding great deals rather than trying to do everything manually.

Stealth Seller has changed how many arbitrage sellers operate by automating the discovery of profitable products. It's like having someone work for you 24/7 that tells you whenever successful sellers add new inventory.

It's definitely worth it to use SellerAmp as well - it's a great calculator for checking profits. Using Keepa, Stealth Seller, and SellerAmp together is going to be a great investment that will pay for itself many times over as you grow your business.
