Best Amazon Arbitrage Software for 2026: Online, Retail and Wholesale Tools

For online arbitrage, start with an analyzer that checks deals, then add a scanner that finds them. SellerAmp SAS analyzes a product from $19.95 a month, and Tactical Arbitrage scans 1,400+ retail sites on its $89-a-month Online Arbitrage plan. Keepa’s free charts show price history. Wholesale buyers who start from brands should look at SmartScout. All prices checked 10 October 2026.

How we picked. We sorted the tools by the job they do (online sourcing, deal analysis, retail scanning, wholesale and validation) and compared each on its published plans, free trial and marketplaces, read off each vendor’s own pricing page on 10 October 2026. We compare what each plan includes and costs rather than match accuracy or deal quality, which depend on your own sourcing workflow; how we test explains our method.

The ten Amazon arbitrage tools compared

“Best for” is the job each tool does best at its entry price, judged from its own plan pages. Most of the paid tools offer a free trial on at least their cheaper plans; Keepa and SmartScout don’t. Trial lengths are in each section below.

Online sourcing: tools that find the deals

Tactical Arbitrage: the widest online scanner

Tactical Arbitrage scans online retailers and matches their products to Amazon listings; its homepage counts 1,392 sourcing sites and markets it as “1,400+”. Besides retailer scans, it has Reverse Search (start from an Amazon category and find cheaper sources), Wholesale Search (upload a supplier manifest; the plan cards call it Wholesale Finder) and Library Search for books. Its homepage says it supports selling accounts in 12 Amazon marketplaces, including the US, UK, Germany, France and Australia; its Threecolts product page says 13.

Tactical Arbitrage is now part of Threecolts, and its own pricing link redirects to Threecolts’ Seller 365 page. The standalone plans are on Threecolts’ Tactical Arbitrage page (checked 10 October 2026), each with a 7-day free trial and unlimited users:

Flip Pack and Wholesale don’t include retail-site Product Search, so retail-site scanning, the job most people buy Tactical Arbitrage for, starts on the $89 Online Arbitrage plan.

Threecolts also sells it inside Seller 365, a bundle with InventoryLab, SmartRepricer, FeedbackWhiz and the ScoutIQ, Scoutify and ScoutX scanning apps. Reseller plans cost $69, $129 or $199 a month, or $65, $119 or $183 a month billed annually, and include reimbursement recovery at a 15% commission (5% on the top plan) (Threecolts, checked 10 October 2026). The 14-day free trial gives 7 days at sign-up and 7 more once you connect an Amazon or Walmart seller account. The $69 entry plan includes Tactical Arbitrage and costs less than the $89 standalone Online Arbitrage plan, but it is single-user, and Threecolts’ plan cards and comparison table disagree on its scan limits, so confirm them before you buy.

• Best for: sellers who want the most sourcing modes in one scanner and will spend time setting filters.
• Watch out for: six plans with different search modes; check that the plan you pick includes the search type you need.

SourceMogul: one plan, UK and US

SourceMogul has a single plan: $79.99 a month or $799.99 a year in the US, and £79.99 a month or £699.99 a year in the UK (SourceMogul’s pricing, checked 10 October 2026). SourceMogul says it scans 700+ UK and US retailers around the clock, and its Chrome extension, included in every plan, shows profit and ROI on retailer pages. The free trial needs no card; the page says 3 days in most places and 7 days on the US monthly card.

• Best for: UK sellers and anyone who wants one plan without tiers to compare.

Deal feeds: Nepeto and ArbiSource

Deal feeds scan suppliers for you and list products that already pass a profit check.

Nepeto starts at $29 a month ($243.60 a year), with Advanced at $62, Pro at $78 and Master at $83 a month, and every plan has a 14-day free trial (Nepeto’s pricing, checked 10 October 2026). Nepeto says it scans retailers, distributors and wholesale suppliers, and its higher plans add Amazon-to-Amazon flips, out-of-stock leads and, on Master, a CSV scanner and live search.

ArbiSource costs $54.99, $74.99 or $99.99 a month for its three US plans, with a 7-day free trial and two months free on yearly billing (ArbiSource, checked 10 October 2026). The entry plan includes store scans, reverse search and a SellerAmp SAS integration; the middle plan adds category and wholesale scans, price drops and bulk restriction checks.

• Best for: sellers who would rather review a list of leads than build scans.

Deal analysis: checking a product before you buy

SellerAmp SAS: the cheapest full analyzer

SellerAmp SAS costs $19.95 a month or $199.50 a year for up to 1,000 product analyses a month. Unlimited lookups cost $29.95 ($299.50 a year), and the team plan $49.95 ($499.50). Every plan has a 14-day free trial (SellerAmp’s pricing, checked 10 October 2026). Every plan includes the profit and ROI calculator, offer and stock counts, historical price and sales charts, intellectual-property and private-label alerts, Buy Box analysis and the mobile app, web app and Chrome extension. It covers seven Amazon marketplaces: the US, UK, Canada, France, Germany, Spain and Italy.

• Best for: most online and retail arbitrage sellers who need a fast buy/no-buy check.

BuyBotPro: automated deal scoring

BuyBotPro’s US plans cost $39.95, $54.95 or $129.95 a month, or $399.50, $549.50 or $1,299.50 a year, and the two cheaper plans come with a 30-day free trial (BuyBotPro, checked 10 October 2026). Every plan includes desktop and mobile access. BuyBotPro says it analyzes a deal in under 7 seconds, suggests a purchase quantity, applies for auto-ungating and calculates UK VAT; it covers the US, Canada, UK, France, Italy, Germany and Spain, and includes a wholesale price-list analyzer.

• Best for: sellers who want the tool to score the deal for them, especially UK sellers dealing with VAT.

Seller Assistant: wholesale lists and restriction checks

Seller Assistant, at sellerassistant.app, is not Helium 10’s Seller Assistant extension, which Helium 10’s help center says has been discontinued. It has three self-serve plans (Seller Assistant’s pricing, checked 10 October 2026):

Pro and Business come with a 14-day free trial. Pro includes 10,000 extension lookups a month, a Bulk Restriction Checker and 3,000 price-list scans a month. Business raises the price-list quota to 150,000 scans a month (300,000 on yearly billing), expands the repricer from 3 actively repriced products to 250 (6 and 500 on yearly billing), and adds the API and an MCP server.

• Best for: wholesale buyers checking supplier price lists and brand restrictions in bulk.

Keepa: the history check

Keepa’s price-history charts are free in its browser extension, and they answer the question every analyzer is trying to answer: has this price held, or is it a spike? Keepa Pro costs €29 a month or €290 a year, billed only in euros, with no trials or coupons (Keepa’s FAQ, checked 10 October 2026). Keepa lists Product Finder, Buy Box statistics, offer-count and sales-rank graphs and the full Deals table among Pro’s benefits. Keepa says Pro is per seat and can’t be shared within an organization. Our Helium 10 vs Keepa comparison shows what Keepa covers next to a full seller suite.

Retail arbitrage: scanning in store

Retail arbitrage happens on a phone, so the scanning app matters more than the desktop tool:

• SellerAmp SAS includes its mobile app on every plan.
• BuyBotPro includes mobile access, through its BuyBotGo app, on every plan.
• Seller 365 bundles Threecolts’ Scoutify (“instant retail arbitrage insights on the go”) and ScoutIQ, a book-scanning app.
• Amazon’s Seller app is free. Amazon says you can scan a barcode or point the camera at a product to see whether it is sold on Amazon, and compare competitor offers (Amazon).

Wholesale: starting from brands and price lists

Wholesale buyers need two things the online scanners don’t focus on: which brands to approach, and which lines on a supplier’s price list are profitable. For the first, our Amazon brand research tools guide compares the options in more depth.

SmartScout covers the brand side. Its plan comparison lists Brand Sellers, which shows every seller under a brand, on Essentials, and the Sellers Database, Seller Map and Seller Offers on Business. SmartScout Basic costs $29 a month billed yearly, or $49 month to month. Essentials is $99 billed yearly ($119 monthly) and Business is $239 billed yearly ($299 monthly) (SmartScout’s pricing page, checked 10 October 2026); our SmartScout pricing guide lists what each plan adds.

Basic includes the UPC Scanner, SmartScout’s price-list scanner, for 5,000 ASINs. SmartScout’s Chrome extension, which checks your selling eligibility through Amazon’s SP-API, offers 100 free uses a month according to its store listing. There is no free trial; each self-serve plan has a 7-day money-back guarantee for new customers. Our SmartScout wholesale guide walks through the workflow.

For the price-list side, Seller Assistant’s Price List Analyzer, Tactical Arbitrage’s Wholesale plan and BuyBotPro’s wholesale analyzer all take a supplier file and return the profitable lines.

Example stacks and what they cost

Monthly prices on monthly billing, checked 10 October 2026:

• Online arbitrage starter: SellerAmp SAS ($19.95) plus Tactical Arbitrage’s Online Arbitrage plan ($89) plus Keepa’s free charts comes to about $109 a month.

If you also sell your own products, our product research tools guide covers the private-label side, and our roundup of the best Amazon seller tools covers the rest of the stack.

How to choose Amazon arbitrage software

1. Match the tool to how you source. Online arbitrage needs a scanner, retail arbitrage a phone app, and wholesale a price-list analyzer.
2. Check the marketplaces. Several of these tools cover the UK and EU, but not all of them cover every Amazon store.
3. Look for restriction and IP checks. SellerAmp SAS, Seller Assistant and BuyBotPro all list intellectual-property or restriction checks, and one missed restriction can cost more than a year of the subscription.
4. Use the free trial on your own buy criteria. Run the same leads through two analyzers and compare the fees and profit they show.
5. Add up the stack. At the entry plans here, a scanner plus an analyzer costs from about $50 to about $130 a month; know the total before you start.

Resellers who sell through FBA should also check what Amazon owes them for lost or damaged stock; our guide to Amazon reimbursement software compares the services and their fees.
