Description
SentryKit is the Amazon Seller Intelligence platform — an amazon buy box monitor with 20+ alert types covering every layer of your listing. Hijackers. Buy Box losses. Amazon suppressed listing events. Sales velocity swings. Amazon stranded inventory. Pricing shifts. Review spikes. The signal layer to run every Amazon decision on — automated or manual.
Intelligence with automation. Always together. Repricers move your price. AI agents act on your catalog. SentryKit is the intelligence underneath: the signals your repricer, your agents, and you all run on. Use it alongside BQool, Aura, Seller Snap, or any automation stack — every decision runs on better context. Delivered across every marketplace, to email, SMS, Slack, Teams, or webhook.
Amazon Buy Box Monitor & Buy Box Intelligence
Core buy box monitoring built for Amazon: every ASIN you care about, checked continuously, with buy box alerts firing the moment ownership shifts. SentryKit distinguishes Buy Box Lost from Search Suppression — two very different events with very different fixes. Track your amazon buy box wins, learn how to win buy box more often, and get the full event history — not just today's snapshot.
Amazon Hijacker Alert & Competitor Price Alert
The amazon hijacker alert fires the moment an unauthorized seller appears on your listing — with seller-profile enrichment so you know who you're dealing with. The amazon price change alert and competitor price alert surface every move your competitors make — with full price history and floor-price context. Feed it to your repricer, your AI agent, or read it yourself. Same signal, every workflow.
Amazon Suppressed Listing & Listing Health
Search Suppression, Suspended Listing, Add to Cart, Product Details Change, Main Image, Category Change, and Parent Product Change alerts cover every way Amazon can quietly break your listing. If your listing becomes an amazon suppressed listing, you find out when it happens — not when your sales fall off a cliff a week later.
Sales Velocity, Stranded Inventory & Performance Signals
FBA Stock, FBM Stock, and Sales Volume alerts flag anomalies before stockouts compound. Track sales velocity across your catalog and catch amazon stranded inventory the moment it appears — one of the highest-cost, lowest-visibility problems on Amazon. Any amazon sales drop is flagged immediately against your baseline. Best Seller Badge, Amazon's Choice, Subscribe & Save, and FBA Fee Change alerts track the performance and cost signals that move your revenue.
Review & Reputation Monitoring
Latest Reviews and Top Rated Reviews alerts ping you the moment a 1-2 star review lands — so you can respond within the window that matters, not two weeks later. Verified/unverified flags, star histories, and review-velocity anomalies all logged and searchable.
Multi-Channel Delivery
Alerts are delivered where you actually work: email, SMS, Slack, Microsoft Teams, webhook, or the SentryKit dashboard. Set routing rules per alert type, per team member, per client. Daily digests for account managers. Full historical record of every signal, searchable.
Amazon Buy Box Software for Agencies
Whether you monitor 1 ASIN or 1,000, SentryKit handles it. Purpose-built amazon buy box software for agencies managing 50+ client accounts: shared workspaces, role-based routing, custom notification rules per client, daily team digests, and flexible commission and permission models. One dashboard, every client, every marketplace.
"SentryKit allows us to manage several ASINs at once by automatically tracking any changes to our listings. The alerts are fast and allow our team to respond in an efficient manner. This app has saved us a lot of money and is one of the most important apps we use." — Divine Bounty, Amazon seller
