The report card
Best for wholesale and arbitrage sourcing on Amazon
Seller Assistant is a browser extension plus tools for checking restrictions, analysing supplier price lists and repricing, aimed at wholesale and online-arbitrage sellers. Pro is $24.99 a month billed yearly, but the repricer needs Business at $69.99 or a $29.99 add-on, and profitability is still in beta.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Pro is $24.99 a month billed yearly ($29.99 monthly), a touch under the $39 middle for Amazon seller tools. The repricer and API sit on $69.99 Business. |
| Free plan and trial | C | A 14-day trial on the Business plan. The listing doesn't say whether it needs a card, and there is no free plan. |
| Features | C | Extension, restriction checker, IP-Alert, price list analyzer, repricer, purchase orders. The repricer needs Business or an add-on, and profitability is labelled beta. |
| Ease of use | C | No store rating on record. An extension plus several tools and supplier lists to set up. |
| Platforms and integrations | B | Web and a Chromium extension, with an API, MCP server, Zapier, Make and n8n from Business up. No desktop or phone app. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Seller Assistant App is for
- Fits if you source by wholesale or online arbitrage and check many products a day
- Makes sense if you want restriction and IP checks beside your profit numbers
Who it is not for
- Pricey if you want the repricer: it needs Business at $69.99 or a $29.99 add-on
- Tight if you grow: extra lookups are $2.99 a month per 1,000 and an extra user is $14.99
- Skip it if you want a free plan, because there isn't one, only a 14-day trial
- Watch out: the Business repricer covers 250 products on monthly billing and 500 on yearly
- Watch out: the Profitability tool is labelled beta
Good to know
Good for
- Amazon wholesale and online arbitrage sellers sourcing from supplier lists
- Sellers who want repricing and purchase order tracking in one tool
- Agencies running many seller accounts
Worth knowing
- Some limits differ by billing period: the Business repricer covers 250 products monthly or 500 yearly.
- Extra usage is paid for separately, such as $2.99 a month per 1,000 extra lookups or $14.99 a month for an extra user.
- Profitability is labeled beta, and the repricer needs the Business plan or a $29.99 a month add-on.
- The extension is listed for Chromium-based browsers; no desktop or mobile app is named.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Seller Assistant App you would be making data from Amazon's seller tools and years of sales estimates. That is not a weekend's work, with an AI app builder or without one.
It costs $299.88 a year.
What you could make
- Inventory: an app builder makes this well.
What you could not
- Data from Amazon's seller tools and years of sales estimates.
- Connections to other products, each kept working as those products change.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Seller Assistant App’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
