Price & Stock Change Alerts

Automated monitoring with instant notifications via email, Slack, or SMS when competitors change prices or go out of stock.

What I Track

Price and stock monitoring isn't about collecting data — it's about knowing the instant something changes that requires your attention. Here's everything I track.

Price Changes

Real-time price monitoring across all tracked products and competitors, with alerts triggered the moment prices shift beyond your thresholds.

Daily Scans Threshold Rules Historical Data Cross-Platform
  • Automated daily price capture across all competitors
  • Configurable percentage and absolute change thresholds
  • Historical price trend data for pattern recognition

Stock Status

In-stock and out-of-stock transitions, low inventory warnings, and restock detection — know when competitors can't fulfill and you can capture their customers.

In-Stock Out-of-Stock Low Inventory Restock Alert
  • Real-time stock availability monitoring
  • Competitor out-of-stock opportunity alerts
  • Restock detection when competitors return to market

Buy Box Changes

Buy Box ownership tracking that shows who wins, who loses, and the price and fulfillment conditions that flip the switch.

Buy Box Winner Ownership History Price Triggers Fulfillment
  • Buy Box ownership tracking with timestamp logs
  • Price and fulfillment method correlation analysis
  • Alert when you lose Buy Box with reason analysis

New Competitor Entries

Detect when new sellers appear on your listings, enter your category, or launch competing products — before they take your market share.

New Sellers Listing Hijacks Category Entrants Catalog Expansion
  • New seller detection on your product listings
  • Category-level new product launch monitoring
  • Unauthorized seller identification and reporting

MAP Violations

Minimum advertised price breach detection across every channel — with timestamped evidence for enforcement.

MAP Monitoring Violation Evidence Channel Scan Seller ID
  • Cross-channel MAP violation scanning
  • Timestamped screenshots for violation evidence
  • Violation frequency tracking per seller

Custom Thresholds

Configurable alert rules per product, category, or competitor — so you only get notified about changes that actually matter to your business.

Per-Product Rules Category Rules Priority Levels Quiet Hours
  • Product-level alert threshold customization
  • Category-wide default rules with override capability
  • Smart batching to prevent notification overload

Every Project Is Different

I scope every engagement individually based on your data, goals, and timeline. No cookie-cutter packages — just a solution built around what you actually need.

Data Volume

Number of SKUs, pages, or data points to process drives the scope of the project.

Delivery Format

Raw CSV, live dashboard, API integration, or automated reporting — each has different complexity.

Ongoing Support

One-time delivery versus ongoing monitoring, maintenance, and iteration on results.

Let’s Discuss Your Project

How It Works

1

Configure

Define which products and competitors to monitor, set threshold rules, and choose alert channels (email, Slack, SMS).

2

Monitor

Automated scrapers check competitor prices daily and compare against your thresholds and historical baselines.

3

Alert

When thresholds are breached, you get instant notifications with context: which product, which competitor, old price, new price, and recommended action.

4

Report

Daily digests summarize all price movements. Weekly reports show trends, your competitive position, and price gap analysis.

Expert Insight

Threshold Methodology: Signal vs. Noise

The art of price alerting is separating signal from noise. A good threshold system uses three layers: absolute thresholds (alert if competitor price drops below $X), percentage thresholds (alert if price changes more than Y%), and statistical thresholds (alert if price deviates more than 2 standard deviations from the 30-day average).

The statistical approach catches anomalies that flat thresholds miss. A product that normally fluctuates within a narrow band suddenly dropping well below that range is significant even if the absolute change seems small. The statistical model flags it because it's unusual — and unusual price movements usually signal something strategic.

Alert Routing: Right Message, Right Channel

Not all alerts deserve the same urgency. I build three tiers: Critical (competitor undercuts your best-selling product by 10%+) → SMS/Slack instant notification. Important (competitor out of stock, new product launch) → Email with action items. Informational (minor price changes, review count updates) → Batched into daily digest. This prevents alert fatigue while ensuring you never miss what matters.

Alerts you own — no monitoring subscriptions.
