Best Online Arbitrage Software: 13 Tools Compared

Ask AI to summarize this article:
Short answer: there is no single best online arbitrage tool, because the work splits into four jobs and almost no tool does more than two of them. Scanning retailer catalogues in bulk, grading one Amazon listing at a time, matching a wholesale price list, and repricing what you bought are four different products. This page compares thirteen tools on those four jobs and on the price each vendor publishes, so you can see which combination you actually need.
Most "best tools" lists do not tell you what each tool is for
A list of names sorted by preference is not much help when the tools are not doing the same thing. SellerAmp and Tactical Arbitrage both appear on every list, and they are not alternatives to each other: one grades a product you already found, the other finds products. Buying the wrong one does not give you a worse version of what you needed. It gives you nothing you needed.
So the useful question is not "which is best". It is "which of the four jobs am I paying someone to do, and which am I still doing by hand".
The four jobs, and what each one means
| Job | What it does | What it looks like without software |
|---|---|---|
| Bulk store scan | Compares whole retailer catalogues against Amazon and returns what clears your profit floor | Opening retailer sites and checking products one by one |
| Single-product analysis | Shows profit, fees, rank and competition on the Amazon page you are looking at | A spreadsheet and the Amazon fee calculator in another tab |
| Wholesale list matching | Takes a supplier spreadsheet of thousands of lines and matches it to Amazon listings | Pasting UPCs into Amazon search, line after line |
| Repricing | Moves your price as competitors move theirs, inside limits you set | Checking your own listings by hand and losing the Buy Box overnight |
Reverse search sits alongside these. It starts from an Amazon listing you want to sell and works backwards to a store that stocks it, which is the opposite direction from a store scan. Our own guide to reverse sourcing covers the method in detail.

One more name belongs here and is not in the table. SourceMogul covered Amazon US and UK and is no longer on sale, which is worth knowing if an older list sent you looking for it. We wrote separately about what to move to.
How many of the thirteen do each job
Counted from the same records the table above is built from, where a tool is only marked as doing a job if it does the whole job rather than part of it.
| Job | Tools that do it | Which ones |
|---|---|---|
| On-page analyser (a Chrome extension) | 10 of 13 | All except Tactical Arbitrage, Analyzer.Tools and RocketSource |
| Wholesale list matching | 8 of 13 | Tactical Arbitrage, Seller Assistant, Analyzer.Tools, Scan Unlimited, RocketSource, ProfitPath, ArbiSource, us. The middle three do only this |
| Reverse search | 5 of 13 | Tactical Arbitrage, Seller Assistant, ProfitPath, ArbiSource, us |
| Bulk store scan | 4 of 13 | Tactical Arbitrage, ProfitPath, ArbiSource, us |
| Repricer in the same subscription | 1 of 13 | Us |
Only four of the thirteen scan stores in bulk
This is the finding that surprises most people reading a list of arbitrage tools. Tactical Arbitrage, ProfitPath, ArbiSource and Arbitrage Hero take a retailer's whole catalogue and compare it against Amazon. Seller Assistant does part of it. The other eight do not do this job at all, whatever the list they appear on says.
If your sourcing session starts by opening retailer websites and checking products by hand, discovery is your bottleneck, and only a bulk scanner removes it. A single-product analyser makes the checking faster once you have arrived at a product. It does not get you there.
Repricing is nearly always a separate bill
Of the twelve tools next to us, none includes a repricer in the same subscription. Tactical Arbitrage's bundle contains one as a separate app, SmartRepricer, and Seller Assistant does part of the job. Everyone else leaves it out, so a working setup usually means a sourcing subscription plus a repricing subscription plus whatever you use for cost tracking.
That matters more than it sounds. A product you bought on a 40% margin stops being a 40% margin the week three other sellers undercut you, and nothing in a sourcing tool notices. Arbitrage Hero includes repricing and cost tracking at every tier, which is the reason the comparison above is on total price rather than on feature counts.
Where the other tools are stronger than we are
Three honest gaps, because a comparison that finds no fault with its own author is an advertisement. Tactical Arbitrage lists 1,400+ source sites against our hundreds, and covers twelve Amazon regions against our two. Keepa's price history is deeper than anything we generate ourselves, which is why our own charts read it. Helium 10 and Jungle Scout are built for private label research, a job we do not do at all.
If you sell in Germany, Japan or Australia, or you are researching a brand of your own, those tools are the better fit and we would rather say so than sell you the wrong subscription.
If you sell on Amazon UK
The UK is smaller than the US market and worse served by this category. Of the thirteen, Arbitrage Hero, Tactical Arbitrage, ArbiSource, SellerAmp, Seller Assistant and BuyBotPro all work on Amazon UK; ProfitPath is built for EU and UK sellers specifically. The three wholesale list scanners are Amazon-wide but their store coverage is US-weighted, and SourceMogul, which did cover the UK, has closed.
The practical difference for a UK seller is store coverage rather than features. A scanner with 1,400 source sites is not useful if 1,300 of them do not ship to a UK address, so check the retailer list against the shops you would really buy from before you judge on the headline number. Ours is published at supported stores.
What to do with this
- Name the job you are stuck on. Finding candidates, checking them, matching a supplier list, or holding your price. Buy for that job, not for the longest feature list.
- If discovery is the bottleneck, you need a bulk scanner, and there are only four to choose between. Nothing else on the list removes that work.
- Add up the whole stack, not one subscription. A cheap sourcing tool plus a repricer plus a cost tracker is usually more than one tool that carries all three.
- Check store coverage against your own shortlist of retailers, especially in the UK. The headline count of source sites tells you very little.
- Use the trials. Most of these offer a trial or a free tier, and the ones that publish a length run from seven to thirty days. One evening of real sourcing tells you more than any comparison table, this one included.
Frequently asked questions
What is the best online arbitrage software?
There is no single answer, because the tools do different jobs. If you need products found for you, the choice is between the four bulk scanners: Tactical Arbitrage, ProfitPath, ArbiSource and Arbitrage Hero. If you already find products and want them graded faster, SellerAmp or BuyBotPro do that job and cost less. If you work from supplier spreadsheets, a wholesale list scanner is the right category instead.
Is there free online arbitrage software?
Partly. Keepa lets you browse price history without paying, and RocketSource and Scan Unlimited both publish a free tier for wholesale lists. There is no free bulk store scanner, because scanning means fetching and matching millions of retailer products against Amazon every day, which costs the vendor real money. Free tools are worth using alongside a paid scanner rather than instead of one.
Do I need a repricer as well as a sourcing tool?
If you sell anything that other people also sell, yes. Buy Box share moves with price, competitors change theirs several times a day, and a margin you calculated at purchase does not survive that on its own. The question is whether it is a second subscription or part of the first one, which is why the price column above is worth reading as a total rather than per tool.
Which online arbitrage software works on Amazon UK?
Arbitrage Hero, Tactical Arbitrage, ArbiSource, SellerAmp, Seller Assistant and BuyBotPro all support Amazon UK, and ProfitPath is built for EU and UK sellers. What separates them in practice is which British retailers they actually cover, so compare the store lists rather than the marketplace count. SourceMogul used to be a common UK answer and is no longer trading.
Is online arbitrage still profitable enough to pay for software?
It depends on how much you buy. Any tool has to earn back its own subscription before it is worth anything, and whether it does depends on how often you buy, what margins you work at and what Amazon's fees take. A tool cannot make that happen on its own, and none of these will find deals for someone who is not sourcing. We looked at what has got harder and what still works in a separate article on whether online arbitrage is still worth it.
