SellerAmp vs Seller Assistant (2026): Which Should You Buy for Online Arbitrage?

SellerAmp vs Seller Assistant: which should you buy for online arbitrage?

Buy SellerAmp SAS if you check deals one at a time and may also scan in stores: every plan bundles a Chrome extension, web app and mobile app with Keepa-licensed charts, from $19.95/month (checked October 2026). Buy Seller Assistant if your sourcing is browser-only and list-heavy: it restriction-checks whole ASIN lists and gives virtual assistants sub-accounts, with its Pro plan at $299.99/year on annual billing. For a solo online-arbitrage seller, SellerAmp is the cheaper, more complete default.

This comparison is built from SellerAmp's and Seller Assistant's own pricing, feature and FAQ pages, plus each vendor's published comparison of the other, rather than first-hand use. Where the two vendors disagree, both versions are printed.

What each tool actually is

SellerAmp SAS: three apps, one analysis history

SellerAmp's FAQ describes SAS (Sourcing Analysis Simplified) as "3 tools in 1 subscription (web app, mobile app, Chrome extension)" built to answer the sourcing questions that start with "Can I sell it?". The idea is that you set your rules once and the software grades every product against them. Per the features page, you "Tell SAS your objectives in your settings, and let SAS tell you if a product meets your designated goals like: Profit ROI BSR minimum/maximum", and SAS "also factors in your tax status, additional sourcing costs and inbound FBA shipping rates, once you set up the rates."

The mobile app is the part Seller Assistant does not match. SellerAmp calls it "the perfect tool for RA" and says you can "Scan a product UPC or EAN, search by text, or use your device Share feature to open SAS analysis on a product you find in another app." Its comparison page sums up the two things it adds over Seller Assistant: "a true mobile app with barcode scanning for retail arbitrage in stores, and Keepa-licensed history charts built into every lookup." Product discovery is built in too, through "Advanced Search (200+ criteria), Smart Search and Storefront Search", and the features page explains that "SAS Storefront Search enables you to see SAS analysis for the products in any seller's storefront." Exports go "to one or more Google Sheets", and if you reprice with BQool, SAS can "Sync cost, min & max price, and repricing rules both ways".

One hard limit to know before you buy: per the FAQ, "SAS is not compatible with Chrome derivatives like Chromium or Safari, or with other browsers (Firefox, Edge, Explorer)." Marketplace coverage, in SellerAmp's words, is "US, Canada, UK and major European marketplaces, with marketplace-aware fees, VAT and currency."

Seller Assistant: a browser extension that grew into a sourcing platform

Seller Assistant's extension puts the same kind of deal check on Amazon pages. Its features page lists "key product data, Lookup Links, FBM & FBA Calculator, Offers, Variation Viewer, Alerts and Flags, Sales Estimator, Stock Checker, Notes, and Restriction Checker", and says the calculator works out "product profit, ROI and margin, Amazon FBA and FBM fees, break-even point, logistics costs, sales tax, and VAT, directly on the Amazon product pages." Risk flags cover "restricted, hazmat, fragile, meltable, adult products, and generic brands", and the charts are "interactive Keepa-driven charts to evaluate product sales history and historic price details."

The supplier side is where it pulls ahead for online arbitrage. The extension's notes and flags follow you off Amazon: the features page describes them "on Amazon product and search pages, in Side Panel View on supplier websites, and Seller Central inventory pages", and research results go out with "Export product research results to Google Sheets in one click." SellerAmp's own description of its rival is fair: "It runs in the browser only, with a side panel on supplier websites, a storefront widget, IP alerts and a bundled VPN."

Two capabilities have no SellerAmp equivalent on the pages we read. The Bulk Restriction Checker handles lists; Seller Assistant's comparison page describes "eligibility on your account, IP complaints, hazmat, meltable, fragile, and more, shown on-page by the Seller Assistant Extension and in bulk with the Bulk Restriction Checker", across lists of up to 20,000 ASINs. And sub-accounts let you "Create accounts for employees and virtual assistants and check product restrictions without access to Amazon Seller Central account." For a seller who sources from supplier spreadsheets with help from a VA, that is the whole job. Check the price at sellerassistant.app

Pricing, as each vendor prints it

SellerAmp publishes three plans on its pricing page: "Getting Started $19.95/month, Getting Serious $29.95/month, Going Pro $49.95/month (UK pricing available; annual billing gives 2 months free)." It adds that "Every plan includes the profit calculator with fees, ROI and profit, eligibility and IP alerts, historical price and sales charts, Buy Box analysis, and the Chrome extension, web app and mobile app", and that "All plans start with a 14-day free trial and can be cancelled anytime." The tiers differ by scale rather than by analysis: Seller Assistant's comparison page characterises them this way, "SellerAmp's plans meter extension and app installs; its team-focused features arrived with the Going Pro tier." Our SellerAmp pricing breakdown covers what each tier unlocks; treat any figure there as older than this page.

Seller Assistant prices by usage. The Pro plan on the pricing page comes with "2 seats", the "Seller Assistant® extension 10k lookups/mo", a "Bulk Restriction Checker 4k ASINs checks/mo" allowance and "IP-Alert® and VPN by Seller Assistant", with a "14 day free trial". On annual billing the page shows "$359.88 $299.99/year billed annually", the first figure struck through, so the annual plan is $299.99/year against $359.88 for a year of monthly payments. The Business tier shows "$959.88 $839.88/year billed annually" and adds "Repricer 250 actively repriced products" and a "Price List Analyzer 150k Product scans/mo". One policy difference matters: Seller Assistant states "We do not offer refunds as our service is subscription-based. We recommend using our free trial before subscribing."

Side by side

Which one fits your kind of online arbitrage

You check deals one at a time on retailer sites. SellerAmp. The analysis is the same shape in both tools, but SellerAmp gives you the mobile app and the Keepa-licensed charts on the cheapest plan, and the Getting Started price is lower than anything on Seller Assistant's page. If you ever walk into a clearance aisle, the same subscription scans the shelf.

You work from supplier price lists or storefront dumps. Seller Assistant. A list of a few hundred ASINs is not a job for a one-product extension; the Bulk Restriction Checker and the Price List Analyzer exist for exactly that workflow, and Seller Assistant's own comparison says it "is the stronger choice when online sourcing, bulk lists, or team workflows are where your time goes."

You run virtual assistants. Lean Seller Assistant. Its sub-accounts let a VA check restrictions "without access to Amazon Seller Central account", and the Pro plan already includes 2 seats. SellerAmp's team features sit on its Going Pro tier, which is its highest plan.

You mix retail and online arbitrage. SellerAmp, without much debate. Even Seller Assistant concedes the point on its own comparison page: "If in-store barcode scanning is the heart of your sourcing, SellerAmp's mobile app is genuinely the best tool for that job, and some sellers run both."

You sell from the UK or into Europe. Either. SellerAmp lists "marketplace-aware fees, VAT and currency", and Seller Assistant's calculator handles "sales tax, and VAT" on the product page. SellerAmp's features page also offers a view of "the viability of selling in European marketplaces" with a choice "between EFN and Pan-EU fulfilment."

The two alternatives people usually shortlist alongside these

BuyBotPro takes the opposite philosophy to SellerAmp's "show every data point" approach: it grades the deal for you before you commit, and it is priced in pounds first with a US table behind a link, so check the current price in your currency. Our SellerAmp vs BuyBotPro comparison and BuyBotPro review cover its deal score, its IP check and its companion mobile scanner. Check the price at buybotpro.com

Tactical Arbitrage is the bulk scanner, and it is now sold inside Threecolts' Seller 365 bundle, which its page describes as "ten tools in one subscription", "Starting at $69/month", with a "14-day free trial". That is a different purchase: it finds deals across retailer catalogs rather than analysing one you found. Our SellerAmp vs Tactical Arbitrage comparison explains the single-scan versus bulk-scan split. Check the price at tacticalarbitrage.com
