The uncomfortable truth

While you slept,
you lost six sales.

A competitor undercut you at 2am. Your Buy Box vanished. Your ranking started sliding. You found out at 9am. That's not bad luck — that's the cost of flying blind on Amazon.

📉

Buy Box disappears overnight

One competitor. Two dirhams. Gone. And by the time you notice, the ranking damage is already done.

🔪

Repricing yourself into poverty

Winning the Buy Box at a loss isn't winning. It's just losing slower. Most repricers don't know the difference.

🕶️

Your competitor knows more than you

They know your price floor. They know when you restock. You know nothing about them. That's not a fair fight.

🔥

Ad budget burning on dead listings

PPC spending on suppressed or OOS ASINs isn't a strategy. It's a subscription to disappointment.

How Sentinel works

Connect once.
Run forever.

No dev work. No scraping. No manual exports. Sentinel uses Amazon's own verified, vetted integration workflows — tried, tested, and fully compliant. Set it up in 10 minutes. Then get back to running your business.

01

Connect in 10 minutes

Authorise Sentinel through Amazon's official, Amazon-vetted integration flow. No developer, no scraper, no workarounds. Your live data — pricing, inventory, Buy Box status — flows in automatically from the moment you connect. Both FBA and Easy Ship fully supported.

02

Set your guardrails, then walk away

Tell Sentinel your margin floor and maximum discount per ASIN. That's it. Sentinel handles everything within the boundaries you set — no obscure prices, no rogue repricing, no surprises. You stay in control without having to stay online.

03

Win the Buy Box. Keep the margin.

Anyone can win the Buy Box by pricing at a loss. Sentinel wins it at the highest price the market allows. That's the difference between a repricer and an intelligent repricer. Sentinel doesn't race to the bottom. It finds the floor and holds it.

Core features

Everything your
listings need. Nothing they don't.

🎯
Buy Box Monitor
Real-time ownership tracking across every ASIN. Know the moment you lose it, who took it, how they priced it, and what their playbook looks like. You're not just watching the score — you're watching the game tape.
Intelligent Repricer
Guardrails-first repricing. You set the floor, Sentinel finds the ceiling. No obscure prices. No race to zero. Customers who avoid automation because they feel out of control — Sentinel was built specifically for you.
🔔
Alerts & Reports — your way
Sentinel is built to set up once and run. It won't drown you in a daily dump of notifications you don't need. Configure exactly what you want to know, when. Quiet by default. Loud when it actually matters.
📦
FBA & FBM Aware
Sentinel knows the difference between FBA Prime and FBM listings — and factors it into every repricing decision. Your FBA listings aren't competing on the same terms as FBM. Sentinel treats them accordingly.

FBA and FBM are
not the same game.

Most tools don't care. Sentinel does. Your repricing strategy, Buy Box eligibility, and competitive position are all different depending on how you fulfil — and Sentinel knows it.

FBA — Fulfilled by Amazon

Prime advantage, managed automatically

FBA listings carry the Prime badge and get preferential Buy Box treatment. Sentinel factors this in — you don't need to price as low to win. We protect your FBA margin premium.

  • Buy Box eligibility weighted for Prime
  • Repricer accounts for FBA fee structure
  • Inventory risk alerts before you go OOS
  • Restock signals based on velocity data
FBM — Fulfilled by Merchant

Easy Ship and self-ship, fully supported

FBM doesn't mean second-class. Sentinel understands Easy Ship workflows and helps you compete effectively — with pricing guardrails tuned for your actual cost structure, not Amazon's.

  • Easy Ship fee logic baked in
  • Separate margin floors from FBA listings
  • Buy Box competitiveness score per ASIN
  • Shipping time impact on Buy Box surfaced
What's coming

The Sentinel suite
is warming up.

Buy Box monitoring and intelligent repricing are live. These four modules are in active development. Early access members get them first — and at founder pricing.

Q2 2026
✍️

Listing Assistant

Builds A+ quality Amazon content — titles, bullets, descriptions — based on your product data and what Amazon's own algorithm rewards. Amazon confirms better listings bring better sales. Sentinel makes it effortless.

Q2 2026
🔍

ASIN Hunter

Before you create a new listing, check if your product already exists on Amazon. Avoid duplicate listing battles, find the right ASIN to piggyback, and launch on a foundation that already has traction.

Q2 2026
🖼️

Image Intelligence

More than an image generator. Sentinel crawls multiple online sources in parallel — product imagery, lifestyle shots, brand style — to identify the best visual assets for your listing. Official brand websites are always the safe fallback.

Q4 2026
📊

PPC Intelligence

Correlate your ad spend with Buy Box ownership and organic rank. Stop burning budget on suppressed ASINs. See exactly where every dirham is going — and whether it's actually working.

No dev. No scrape.
Just connect.

Sentinel uses Amazon's own officially vetted integration workflow. If Amazon built the door, we walk through it properly.

1

Authorise your account

One screen. Click, approve, done. Sentinel connects through Amazon's official integration — no tokens pasted into spreadsheets, no third-party scrapers, no grey-area hacks.

2

Set your rules once

Define margin floors, repricing aggression, and alert preferences per ASIN or category. Sentinel is built to be set up once and left running — until you have a major strategy change, you won't need to touch it.

3

Let Sentinel take over

That's it. Sentinel watches, reprices, alerts (only when needed), and reports (only what you asked for). Your mornings are yours again.
