Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 15 of the 25 other Amazon seller tools we grade
SellerEngine makes three Amazon seller tools: Sellery, a real-time repricer; BuyBoxBuddy, an algorithmic repricer with inventory analytics; and Profit Bandit, a scouting app for phones with a web batch version. The company says it launched an automated Amazon pricing tool in 2002.
To get you started, here are 9 things to know about SellerEngine, taken from its own pages and our grades.
You connect your Amazon account and set repricing rules.
- 1
Best for repricing and scouting for Amazon sellers
But Sellery's price isn't on the pages we read, and analytics is an enterprise add-on.
- 2
Paid plans start at $9.99 a month
As its pricing page puts it: $9.99 per month (Profit Bandit mobile app).
- 3
You can try it first
Sellery has a two-week free trial and BuyBoxBuddy a 15-day free trial, no credit card required.
- 4
It runs on 3 platforms
Web, iOS and Android.
- 5
Sellery
Real-time repricing with automatic rules, Smart Lists and sales velocity pricing for private label.
- 6
BuyBoxBuddy
Repricer with preset strategies plus inventory and Buy Box analytics.
- 7
Profit Bandit app
Scans barcodes, shows an estimated profit and works offline with sync.
- 8
A 2.2 GPA, above 15 of 25
That is against the other Amazon seller tools we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace SellerEngine 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.

The report card
Best for repricing and scouting for Amazon sellers
SellerEngine sells two repricers and a product-scouting app, with trials of two weeks and 15 days and no card. The scouting app is $9.99 a month on phones. But Sellery's price isn't on the pages we read, and analytics is an enterprise add-on.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Scouting app $9.99 a month, batch tool $49, BuyBoxBuddy from $50. The category's middle is $37, so the repricer lands in the ordinary band. |
| Free plan and trial | C | Two-week trial on Sellery, 15 days on BuyBoxBuddy, both with no card, plus 20 free scans on the app. |
| Features | C | Two repricers plus a scouting app and batch tool. Analytics and shipping options in Sellery are enterprise extras set up on request. |
| Ease of use | C | No store rating on record. You connect your Amazon account and set repricing rules. |
| Platforms and integrations | B | Web, plus iPhone and Android apps for scouting. |
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 SellerEngine is for
- Fits if you scout stock with your phone and reprice with the same company's tools
- Works for sellers with under 20,000 items on BuyBoxBuddy
Who it is not for
- Skip it if you need Sellery's price, because the pages we read don't show it
- Tight if you stay free: it's 20 scans, then a trial
- Pricey if you want both scouting and batch, since the mobile and batch plans add up
- Watch out: BuyBoxBuddy's three price tiers beyond the $50 entry aren't shown
Good to know
Good for
- Sellers wanting a repricer from a long-running vendor
- Retail arbitrage sellers scanning in stores
Worth knowing
- Sellery's price is not stated on the pages read; the product page offers a trial.
- Analytics and a shipping and fulfillment option in Sellery are enterprise features set up on request.
- BuyBoxBuddy's three price tiers other than the $50 entry are not shown on the page read.

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 SellerEngine 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 $119.88 a year.
What you could not
- Data from Amazon's seller tools and years of sales estimates.
- Scanning barcodes with a phone camera or a scanner.
- A real app for iOS and Android. Something home-made would be a web page.
What this rests on. SellerEngine’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.
