Online arbitrage in the UK has become a speed game. Thousands of sellers scan the same retailers, prices change by the hour, and anyone still working out fees, VAT and Buy Box chances by hand is too slow. This guide compares the online arbitrage tools that matter for UK and EU Amazon sellers in 2026, from sourcing software and wholesale scanners to browser extensions, price trackers and profit dashboards, with current pricing, free trials and a tool stack for every budget.
Key takeaways
No single tool does everything. Most sellers combine a sourcing tool, a browser extension for quick checks, Keepa for price history and a profit tracker. For UK sellers the key questions are which UK retailers a tool covers, whether it handles 20% VAT correctly and whether it can compare Amazon.co.uk with the EU marketplaces. Many well-known tools were built for the US market.
Which online arbitrage tool does what?
Sourcing tools match online shops against Amazon and surface products with a price gap. Wholesale scanners check supplier price lists in one go. Browser extensions and scanner apps show profit, ROI and sales rank on any product page. Price trackers such as Keepa give you price history and alerts, and profit tools such as Sellerboard show what you really earn after every fee. New to the model? Start with our Amazon online arbitrage guide.

Best tools for online arbitrage sourcing
ProfitPath
ProfitPath is built for UK and EU sellers and listed in Amazon's Selling Partner Appstore. According to ProfitPath, Supplier Search scans more than 1,000 shops and over 250 million products every day and calculates live profit for Amazon UK, DE, FR, IT, ES and NL. Reverse Search finds suppliers for up to 1,000 brands at once, Spy Search watches competitor storefronts and A2A Search spots price gaps between Amazon marketplaces. FBA fees, VAT and brand restrictions are already part of every calculation.
Wholesale Basic costs €63 and Wholesale Pro €79 net a month. The Automation plans with Supplier Search, Price Alerts, ProfitGo and ProfitDesk run from €159 for Automation Starter to €503 for Automation Ultimate, net with annual billing. Every ProfitPath plan comes with a 14-day free trial.
Tactical Arbitrage, now only in Seller 365
Threecolts now sells Tactical Arbitrage only as part of Seller 365, a bundle of ten seller tools. It scans more than 1,400 retail sites, supports 12 Amazon marketplaces according to Threecolts and offers six search modes including Product, Reverse, Wholesale, Amazon Flips and Library Search. Its strength is the huge US shop coverage. UK sellers often need to double-check VAT and UK fees, and billing is in US dollars. There is a 14-day trial.
Arbisource
Arbisource is one of the most searched online arbitrage tools in the UK. It offers store scans, reverse search and a vault of ready-made leads. Plans start at £39.99 a month plus VAT with a 7-day free trial, which makes it a solid choice if you mainly sell on Amazon.co.uk and buy from UK retailers.
SourceMogul
SourceMogul says it scans more than 700 US and UK retailers and calculates profit, ROI and sales rank automatically. It is easy to learn, but EU shops are not its focus and billing is in US dollars.
Best tools for wholesale sourcing
The ProfitPath Wholesale Scanner takes supplier lists as CSV, XLSX or PDF, matches every row against live Amazon data and ranks products by profit, with no template needed. Scan Unlimited offers a free plan with one upload a month, and AnalyzerTools handles bulk analysis for large lists. Our guide on how to scan wholesale lists walks you through the process.
A scanner is only as good as your price lists. eany (affiliate link) is a wholesale platform with more than 300 vetted EU suppliers, free shipping from a €300 minimum order and one combined invoice. Qogita (affiliate link) is a European wholesale marketplace for health and beauty with vetted suppliers and an authenticity guarantee. Read our Amazon wholesale guide to find your first supplier.
Best browser extensions and scanner apps
ProfitGo is the ProfitPath Chrome extension and mobile app. On any Amazon page or shop it shows profit, ROI, live FBA fees, BSR, Buy Box statistics and a price comparison across Amazon UK and the EU, including VAT and a WEEE check. Manual Essential costs €16 and Manual Expert €24 net a month with annual billing, and ProfitGo is included in every Automation plan.
SellerAmp SAS is a UK favourite for quick checks: net profit, ROI, sales estimates, eligibility and IP alerts on the product page or in the app, with a 14-day trial on every plan. BuyBotPro analyses deals in one click, including Buy Box history and competition, and its mobile app BuyBotGo is included, with a 30-day trial. For in-store scanning, see our list of the best Amazon scanner apps for retail arbitrage.
Best tools for price history and alerts
Keepa is the standard for Amazon price history: price, sales rank, Buy Box share and seller count over months and years. Basic features with up to 200 alerts are free, full data needs a subscription. Learn to read the charts in our Keepa product research guide. ProfitPath Price Alerts watch Amazon ASINs and products in more than 1,000 shops around the clock and ping you, for example in Discord, when a deal hits your profit target. For simple alerts see Amazon price alerts with Keepa, and CamelCamelCamel remains a free option.
A2A: comparing Amazon UK with the EU
ProfitPath A2A Search compares Amazon UK, DE, FR, IT, ES and NL with VAT and live GBP to EUR conversion included. Our guide to Amazon arbitrage in the UK explains customs, VAT and the best flips after Brexit.
Best tools for profit tracking
Sellerboard shows your real profit after Amazon fees, refunds and ad spend and adds inventory management, PPC analytics, review requests and reimbursements for lost stock, with the first month free. SellerToolkit calculates profit using FIFO cost of goods and tracks reimbursement opportunities, with a 14-day trial. A repricer then keeps your prices competitive within the minimum and maximum you set.
Your tool stack on any budget
Start with around €31 a month: ProfitGo Essential, the free Keepa version and Sellerboard Standard. Once deals are flowing, ProfitPath Automation Starter finds them automatically from €159. At scale, Automation Pro compares all marketplaces and a repricer protects your margins. For the full cost picture, read what it really costs to start Amazon FBA.
UK and EU sellers: why your market decides your tools
A tool with 1,400 US shops helps little if you buy from Argos, Currys or Boots. Check which UK and EU retailers are covered, whether 20% UK VAT and EU VAT are calculated and whether the tool knows Amazon.co.uk and the EU marketplaces. Look for sales rank, Buy Box history, seller counts and eligibility checks, and use the free trial with real products. Unsure which model suits you? Compare online arbitrage, retail arbitrage and private label.
Frequently asked questions
What is the best online arbitrage tool in the UK?
It depends on where you buy. ProfitPath covers UK and EU shops and all six European Amazon marketplaces with VAT built in. Arbisource focuses on UK leads, while Tactical Arbitrage and SourceMogul are strongest in the US.
Is Tactical Arbitrage still sold on its own?
No. Threecolts now sells Tactical Arbitrage only inside Seller 365, together with nine other tools.
Are there free online arbitrage tools?
Yes, with limits. Keepa's basic version and CamelCamelCamel are free, and Scan Unlimited has a free plan with one upload a month. Serious sourcing usually needs a paid tool.
Do I need Keepa for Amazon FBA?
Keepa remains the best source for price history. Many sourcing tools and extensions show price history too, so the free version is often enough at the start.
Is online arbitrage still profitable in 2026?
Yes, but margins are tighter. Tools that scan many shops automatically and include fees and VAT make the difference.
Conclusion
The best online arbitrage tool is the one that fits your market. UK and EU sellers need UK and EU shops, all European marketplaces and correct VAT. Start small with a browser extension and Keepa, then move to automated sourcing once your first deals work. ProfitPath and ProfitGo both come with a 14-day free trial.
