5 Best Amazon Scanner Apps for Retail Arbitrage Sellers (2026)

Walking into a store, scanning a product, and knowing within seconds if it's worth buying — that's the power of a good scanner app. But here's the problem: most scanner apps were built for the US market. If you're selling on Amazon in Europe or the UK, the fees are different, the VAT rules are different, and the margins are tighter. Using the wrong app means trusting the wrong numbers.

In this guide, we compare the best Amazon scanner apps for retail arbitrage in 2026 and break down exactly which one gives you the most accurate data — especially if you sell on European Amazon marketplaces.

What Is an Amazon Scanner App and Why Do You Need One?

An Amazon scanner app is a mobile application (or Chrome extension) that lets you scan a product's barcode and instantly see whether you can sell it profitably on Amazon. Within seconds, you get data like the current Amazon selling price, the number of competing sellers, sales rank history, FBA fees, and your estimated profit.

Without a scanner app, you'd need to manually look up every single product on Amazon, calculate fees, check restrictions, and estimate demand. That takes 5-10 minutes per product. With a scanner app, you get all of that in under 5 seconds.

If you're doing retail arbitrage — buying discounted products from retail stores and reselling them on Amazon — a scanner app isn't optional. It's the core tool that makes the whole business model work.

Here's what a good scanner app should tell you:

• The current Buy Box price and how many sellers are competing
• Estimated FBA fees (referral fee, fulfillment fee, storage fees)
• Your net profit after all costs
• Sales rank and sales velocity (how fast the product sells)
• Whether you're eligible to sell in that category
• Price history so you can spot trends and seasonal drops

The key word here is "estimated." Not all apps calculate fees the same way — and that difference can cost you real money. More on that in a moment.

The Best Amazon Scanner Apps for Retail Arbitrage in 2026

We tested and compared the most popular scanner apps available for Amazon sellers in 2026. Here's our honest breakdown.

1. ProfitGo by ProfitPath

ProfitGo is a Chrome extension and mobile app built specifically for Amazon sellers in Europe and the UK. It was created by ProfitPath, a European Amazon arbitrage software company that works with over 400 active sellers across Germany, France, Spain, Italy, and the United Kingdom.

What makes ProfitGo stand out from every other scanner app on this list is the accuracy of its fee calculation. ProfitGo pulls the exact same fee structure that Amazon uses in its own Revenue Calculator. That means when you scan a product with ProfitGo and then cross-check the numbers in Amazon's Revenue Calculator, you'll get the same profit — down to the cent, with 99.99% accuracy.

This might sound like a small detail, but it's not. Many scanner apps estimate fees based on outdated category data or simplified formulas. The result? You think you're making €5 profit on a product, but after Amazon takes their actual fees, you're only making €2 — or worse, losing money. ProfitGo eliminates that risk.

Key features of ProfitGo:

• FBA fee calculation that matches Amazon's Revenue Calculator at 99.99% accuracy
• Real-time profit calculation including VAT for European marketplaces
• Barcode scanning via the mobile app (iOS and Android)
• Chrome extension for scanning products directly on retailer websites
• BSR (Best Sellers Rank) and estimated sales velocity
• Category eligibility and restriction checks
• Reverse search — find where a product is available cheaper across retail and online stores

• Source on any site — activate ProfitGo on any retailer website and instantly see profit data for every product on the page
• Cross-marketplace calculation — compare profit margins between different Amazon marketplaces (DE, FR, IT, ES, UK) to find the best one to sell on
• Mass scanner — scan large quantities of products in-store rapidly, one after another, without waiting for each result to load
• Storefront scanner to analyze competitor storefronts
• Google Sheets integration for building deal lists
• WEEE registry check (required for selling electronics in the EU)

A few of these features deserve extra attention because no other scanner app on this list offers them. The reverse search lets you take any Amazon ASIN and instantly find where that product is sold cheaper — across online retailers and local stores. Instead of browsing stores hoping to find deals, you start with a product you know sells well and find where to source it. That flips the entire sourcing workflow.

The "source on any site" feature turns every retailer website into a sourcing goldmine. Browse MediaMarkt, Argos, Fnac, or any other store online, and ProfitGo overlays profit data on every single product you see. No need to copy ASINs back and forth — the data is right there on the page.

Then there's cross-marketplace calculation. Say you find a deal in Germany — ProfitGo can instantly show you what that same product would earn on Amazon.fr, Amazon.it, or Amazon.co.uk. Many sellers leave money on the table because they only check one marketplace. This feature makes it easy to spot where the margins are best.

ProfitGo covers all major European Amazon marketplaces (DE, FR, ES, IT, UK) and is designed with European sellers in mind. That means VAT handling, Pan-EU fee structures, and marketplace-specific rules are built in from the ground up — not bolted on as an afterthought.

Pricing: Starting from €15/month with a 14-day free trial

Platforms: Chrome Extension, iOS, Android

Best for: European and UK Amazon sellers who need accurate fee calculations and a complete mobile + desktop scanning solution

2. SellerAMP SAS

SellerAMP is one of the most well-known scanner apps in the Amazon arbitrage space. It offers a Chrome extension and mobile app for scanning products and analyzing deals. Many sellers start with SellerAMP because of its popularity in YouTube tutorials and online courses — most of which are made by US-based sellers.

SellerAMP provides solid features for product research: profit calculation, restriction alerts, Keepa chart integration, storefront analysis, and BSR tracking. The interface is clean and the mobile scanning experience works well.

However, there's a significant caveat for European sellers. SellerAMP was built with a strong US focus. While it technically supports European marketplaces, the fee calculation isn't always accurate for EU sellers. Some category-specific fees aren't updated regularly, and certain costs are estimated rather than pulled from Amazon's actual fee structure. If you compare SellerAMP's profit estimate with Amazon's Revenue Calculator for the same product on Amazon.de or Amazon.fr, you'll often find a noticeable discrepancy.

For US sellers, this might not be a big deal — the US marketplace has a simpler fee structure. But for European sellers dealing with VAT, Pan-EU logistics fees, and marketplace-specific referral rates, these inaccuracies can add up fast.

That said, SellerAMP is still a capable tool with a large community and solid educational resources.

Key features of SellerAMP:

• Profit calculator with ROI and margin estimates
• Mobile barcode scanning
• Keepa chart integration
• IP complaint and restriction alerts
• Storefront explorer
• Quick product overview with eligibility check

Pricing: From $19.95/month (Getting Started) or $27.95/month (Getting Serious)

Platforms: Chrome Extension, iOS, Android

Best for: US-focused Amazon sellers or beginners who follow US-based arbitrage courses

3. Amazon Seller App

The Amazon Seller App is Amazon's own free tool for managing your seller account from your phone. It includes a basic barcode scanner that shows you the current selling price, number of sellers, your eligibility to sell, and estimated profit for both FBA and FBM.

For a free tool, it does the basics well. You can scan products in store, see if you're allowed to sell them, and get a rough idea of potential profit. You can even list products directly from the app.

The big limitations are what it doesn't show you. There's no sales rank history, no average selling price over time, no detailed fee breakdown, and no way to see which seller currently holds the Buy Box. You also can't set custom cost parameters or factor in shipping costs to prep centers.

If you're just getting started with retail arbitrage and want to test the waters without spending money on tools, the Amazon Seller App is a reasonable starting point. But most sellers outgrow it within a few weeks once they realize they need more data to make confident buying decisions.

Key features:

• View current selling price, seller count, and BSR
• Scan barcodes and product packaging
• Check selling eligibility per category
• List products directly from the app
• Estimated profit for FBA and FBM

Pricing: Free

Platforms: iOS, Android

Best for: Complete beginners testing retail arbitrage for the first time

4. BuyBotPro

BuyBotPro is a Chrome extension that provides automated deal analysis for Amazon sellers. When you're browsing a product on Amazon, BuyBotPro pops up with a score and profit estimate, helping you decide quickly whether a deal is worth pursuing.

The concept is good: rather than manually analyzing every metric, BuyBotPro gives you an overall "deal score" that factors in competition, sales velocity, profit margin, and more. It also includes alerts for IP complaints and hazmat products.

The issue with BuyBotPro is data maintenance. Several sellers in the community have reported that some of the data BuyBotPro displays is outdated or inaccurate. Fee calculations don't always match reality, and some product data points seem to lag behind what Amazon actually shows. At $34.95/month for the standard plan, that's a concern worth noting.

BuyBotPro can be useful as a quick screening tool, but you'd want to double-check its numbers with a more accurate calculator before committing to a purchase.

Key features:

• Automated deal scoring system
• Profit and ROI calculation
• IP complaint alerts
• Competition analysis
• Hazmat and restriction warnings

Pricing: From $34.95/month (Standard) or $44.95/month (Professional)

Platforms: Chrome Extension

Best for: Sellers who want a quick, automated deal screening overlay while browsing Amazon

ProfitGo vs SellerAMP: The Fee Accuracy Deep Dive

Since ProfitGo and SellerAMP are the two most directly comparable tools on this list, let's break down the key differences in detail.

Fee Calculation Accuracy

This is the single most important factor when choosing a scanner app. If the fee calculation is wrong, everything else is irrelevant — your profit estimates, your ROI, your buying decisions — all based on bad data.

ProfitGo uses the same fee tables and logic that Amazon's own Revenue Calculator uses. When you scan a product, ProfitGo calculates the referral fee, FBA fulfillment fee, and any additional fees (like storage or oversize surcharges) based on the actual category-specific rates for the marketplace you're selling on. The result: if you check the same product in Amazon's Revenue Calculator, the profit numbers match at 99.99% accuracy.

SellerAMP uses an approximation model that works well for the US marketplace but struggles with European fee structures. Category-specific fees aren't always up to date, and certain marketplace-specific charges (like the Digital Services Tax in some EU countries) may not be factored in. The discrepancy can range from a few cents to several euros per unit — which, across hundreds of products, significantly impacts your actual margins.

Here's a simple test you can run yourself: Pick any product on Amazon.de, calculate the profit in SellerAMP, then check the same product in Amazon's Revenue Calculator. Do the same with ProfitGo. You'll see the difference immediately.

We did exactly that with a Crucial X9 2TB External SSD on Amazon.de. Buy price: €100. Sell price: €179.99. Amazon's Revenue Calculator shows €27.72 profit at 15.40% margin. ProfitGo shows €27.71 profit at 15.40% margin. The numbers are spot on, practically 1:1. Every single fee line matches: €21.40 referral fee, €2.13 FBA fee, €28.74 VAT. That's not an estimate. That's accuracy you can trust your buying decisions on.

European Market Support

ProfitGo was built for European and UK sellers from day one. VAT handling, Pan-EU fee structures, WEEE compliance checks, and marketplace-specific referral rates are all native features. The team behind ProfitGo (ProfitPath, based in Europe) works directly with European and UK sellers and responds quickly when Amazon updates fees or adds new requirements.

SellerAMP supports European marketplaces, but it's clearly designed with the US as the primary market. European features feel like add-ons rather than core functionality. If Amazon changes a fee structure on Amazon.fr or adds a new compliance requirement for Amazon.it, it can take time before SellerAMP reflects that change.

Pricing Comparison

ProfitGo starts from €15/month — priced in euros, for a European audience. 14-day free trial included.

SellerAMP starts from $19.95/month — priced in US dollars. For European sellers, the actual cost depends on the EUR/USD exchange rate, and you may also face international transaction fees from your bank.

Mobile Experience

Both tools offer mobile apps for in-store scanning. ProfitGo is available on iOS and Android with the full feature set, including barcode scanning, profit calculation, and deal analysis. SellerAMP also has solid mobile apps, though some advanced features are Chrome-extension-only.

Features You Won't Find in SellerAMP

Beyond accuracy and EU support, ProfitGo has several features that SellerAMP simply doesn't offer:

Reverse Search: ProfitGo lets you start with an Amazon product and instantly find where to buy it cheaper across retail and online stores. SellerAMP doesn't have this — you're stuck browsing stores manually and scanning items one by one hoping to find winners.

Source on Any Site: With ProfitGo, you can browse any retailer website and see live profit data overlaid on every product. Whether you're on MediaMarkt, Argos, or any other store, the data is right there. SellerAMP only works on Amazon product pages.

Cross-Marketplace Calculation: Found a deal on Amazon.de? ProfitGo shows you what that product would earn on Amazon.fr, Amazon.it, Amazon.es, or Amazon.co.uk — all in one view. SellerAMP calculates for one marketplace at a time, so you'd need to manually check each one.

Both tools offer a mass scanner for rapid in-store scanning, so that's a draw. But the three features above are exclusive to ProfitGo and can seriously change how you source products.

The Bottom Line

If you're selling on Amazon in Europe or the UK, ProfitGo gives you more accurate numbers at a lower price point with better EU market coverage — plus exclusive features like reverse search, source on any site, and cross-marketplace calculation that no other scanner app offers. If you're primarily selling on Amazon.com (US marketplace), SellerAMP is a solid choice with a large community and proven track record.

For European sellers, the fee accuracy alone makes ProfitGo the better choice. But when you add reverse search, sourcing on any site, and cross-marketplace comparison on top, it's not even close.

How to Choose the Right Scanner App for Your Business

Picking the right scanner app depends on three things:

Where you sell. If you sell on European Amazon marketplaces (DE, FR, ES, IT) or Amazon UK, choose a tool that was built for those markets. Fee structures, VAT rules, and compliance requirements are different from the US, and you need a tool that handles them correctly. ProfitGo is the clear choice here.

Your budget. If you're just starting out and want to test the waters, the Amazon Seller App is free and gets you basic data. When you're ready to get serious, ProfitGo at €15/month gives you professional-grade accuracy without breaking the bank. SellerAMP and BuyBotPro cost more — especially when you factor in dollar pricing and potential exchange rate costs.

What you need beyond scanning. Some sellers want an all-in-one ecosystem. ProfitGo includes reverse search, source on any site, cross-marketplace calculation, mass scanning, Google Sheets integration, a storefront scanner, and WEEE checks — all in one subscription. No other tool gives you that range. If you later want to scale into online arbitrage and wholesale, ProfitGo connects seamlessly with ProfitPath, which offers access to 1,000+ suppliers and 200M+ products across Europe.

Frequently Asked Questions

What is the most accurate Amazon scanner app for European sellers?

ProfitGo by ProfitPath offers the highest fee calculation accuracy for European Amazon marketplaces. Its profit calculations match Amazon's own Revenue Calculator at 99.99% accuracy, which is critical for sellers on Amazon.de, Amazon.fr, Amazon.es, Amazon.it, and Amazon.co.uk.

Is the Amazon Seller App good enough for retail arbitrage?

The Amazon Seller App is a free starting point, but it lacks essential features like sales rank history, detailed fee breakdowns, and Buy Box analysis. Most sellers upgrade to a dedicated scanner app like ProfitGo within the first few weeks of doing retail arbitrage.

How much does a good Amazon scanner app cost?

Prices range from free (Amazon Seller App) to $44.95/month (BuyBotPro Professional). ProfitGo offers the best value for European sellers starting from €15/month, with a 14-day free trial to test all features.

Can I use SellerAMP for European Amazon marketplaces?

SellerAMP technically supports European marketplaces, but it was designed with a US focus. The fee calculations for EU marketplaces aren't always accurate, which can lead to incorrect profit estimates. European and UK sellers increasingly switch to ProfitGo for this reason.

Do I need both a Chrome extension and a mobile app for retail arbitrage?

Ideally, yes. Use the mobile app with barcode scanning when you're in physical retail stores, and the Chrome extension when you're sourcing deals online from retailer websites. ProfitGo includes both in a single subscription.
