Price Change Detection Engine for Amazon & OnBuy (UK) – A Real-Time Data Intelligence System by Actowiz Solutions

Introduction

Pricing in eCommerce changes more frequently than any other metric.

On platforms like Amazon and OnBuy (UK), a single SKU can change price:

• every hour
• based on demand
• based on competitor activity
• during lightning deals
• when Buy Box sellers switch
• when stock levels fluctuate

Brands, aggregators, and sellers often lose margins because they cannot see these changes in real time.

Actowiz Solutions solves this problem with a Real-Time Price Change Detection Engine designed for Amazon and OnBuy (UK) merchants looking for full category-level visibility.

This system captures, compares, and analyzes pricing changes across millions of SKUs — giving businesses the ability to react instantly.

Why Real-Time Price Detection Matters

• Protect your margins

If a competitor lowers prices by even £1–£3, your listing can lose ranking and Buy Box share.

• Stay ahead of marketplace sellers

Unauthorized sellers often undercut prices by 5–15%.

• Detect algorithm-driven pricing

Amazon's automated repricers change prices dynamically.

• Identify deal periods

Lightning deals, flash sales, and hourly discounts require immediate action.

• Improve pricing strategy

Visibility across UK marketplaces helps brands set stable pricing structures.

This is why brands rely on Actowiz Solutions for continuous pricing feeds and alerting systems.

How Actowiz Solutions Builds a Price Change Detection Engine

Our system monitors Amazon.co.uk and OnBuy UK across categories like:

• Electronics
• Beauty & personal care
• Fashion
• Toys
• Home & kitchen
• Baby products
• FMCG

Below is the workflow that powers the engine.

1. High-Frequency Crawling Layer

Actowiz Solutions' crawlers capture data in:

• 5-minute intervals
• 15-minute intervals
• hourly cycles
• daily summaries

Brands choose depending on:

• category volatility
• competition intensity

For electronics & FMCG, real-time is mandatory.

2. Price Extraction & Normalization

We extract:

• MRP (List Price)
• Selling Price
• Deal Price
• Coupon Discount
• Shipping Cost
• Seller Price

All values are normalized into GBP (£) for UK pricing.

3. Seller Mapping (Amazon + OnBuy)

We detect:

• Buy Box seller
• Seller ID

• Unauthorized sellers
• New seller listings

This is key for brand protection.

4. Price Change Detection Logic

The system flags:

• Upward changes

Consumer demand spike, low stock, algorithmic increase.

• Downward changes

Competitor price drop, seasonal sale, seller undercutting.

• Deal-based changes

Lightning deals, limited-time promotions.

• New seller discounts

5–20% price drops to gain ranking.

• Cart-level price changes

Amazon sometimes reduces price at checkout — we catch this too.

• Week-over-week volatility
• Month-over-month patterns

Peak volatility is seen during:

6. Price Alerts & API Integration

Brands get:

• Instant alerts (Slack, Email, API)
• Price deviation triggers
• Threshold-based notifications (e.g., ±3% change)
• Category-wide alerts (beauty, electronics, etc.)
