Plug Seller vs Seller Assistant
Seller Assistant is a desk-bound research tool. Plug Seller adds the phone, Walmart, the deal feed and the whole back office.
The short answer
Seller Assistant lives in the browser — there's no mobile app, so no in-store scanning. Plug Seller matches the analysis essentials and adds a native barcode-scanning app, Walmart and Target sourcing, an auto-posting deal feed, Real Share, a built-in repricer and an FBA reimbursement finder — the parts a reseller actually needs to scale, in one app.
Why Plug Seller wins
What you get with Plug Seller that Seller Assistant doesn't
Seller Assistant covers one slice. Plug Seller covers the whole workflow — find the product, prove the profit, then run the business that sells it.
Native mobile app with barcode scanning for in-store retail arbitrage. Seller Assistant is browser-only — a major gap.
Auto-posting deals + Real Share + a Final Verdict. Seller Assistant analyzes the lists you supply.
Walmart analysis and Target → Amazon flips. Seller Assistant is Amazon-only.
Both built in — Seller Assistant has neither.
The units-for-you read and a single verdict on top of the data.

It tells you how many YOU can sell — not just the listing total.
Every other tool shows a listing's total monthly sales and leaves the hard part to you. Plug Seller's Real Share engine estimates the units you can realistically move using Buy Box share and price positioning, then turns it into profit, ROI, months-to-clear and a recommended test quantity — so you don't overbuy.
Everywhere you source
Extension, web and a real phone scanner
One login, one analysis history — at your desk, in the browser, and in the aisle.
Chrome extension
Live profit overlay on every Amazon & Walmart listing — plus a quick-view metric card on every search-result tile.
Web app
The full scanner, Advanced Search, deal feed and My Business at plugseller.com/scan — nothing to install.
Mobile app
Scan a barcode in the aisle and get the verdict in seconds. One analysis history across all three surfaces.
One app, not six
Match Plug Seller with separate tools and you'd run a stack
Seller Assistant handles one job well. To cover everything Plug Seller does in one login, you'd be paying for several single-purpose tools — and still switching between them all day.
The bottom line
One app does Seller Assistant's job — and the rest
Seller Assistant vets lists you supply, at your desk. Plug Seller finds the deals, vets them, scans in-store on your phone, and runs the repricer, reimbursements and inventory — Amazon, Walmart and eBay — from $19.95/mo.
FAQ
Plug Seller vs Seller Assistant, answered
Does Plug Seller have a mobile app?+
Yes — a native iOS app with barcode scanning, so you can source in-store. Seller Assistant is desktop-browser only.
Does Plug Seller find deals for me?+
Yes — an auto-posting deal feed plus Advanced Search and CSV import, with Real Share and a Final Verdict on top.
Does Plug Seller include a repricer and reimbursements?+
Both are built in, plus inventory and accounting. Seller Assistant has neither a repricer nor a reimbursement finder.
Which marketplaces does Plug Seller support?+
Amazon in the US and Canada, Walmart in the US, and eBay — and the same instant verdict, profit, demand and eligibility read in a single scan (eBay demand is based on real sold-comp pricing and live active-listing competition, not a sales rank). Most tools cover just one marketplace. Walmart and eBay are included on the Combo and Pro plans; the Starter plan is Amazon-only.
Is it hard to switch?+
No. Plug Seller runs on the same Amazon and Walmart product pages through the Chrome extension, plus a full web app at plugseller.com/scan and a native iOS app — so the workflow feels familiar, you just get far more in one place. Start the 7-day free trial and run it on the same products you check today.
