ChronoSolver: Memento-Inspired Transaction Memory & E-Commerce Price Audit

Inspired by the fragmented memory narrative of 'Memento' and the data-gathering aspect of an 'E-Commerce Pricing' scraper, ChronoSolver is an accounting software add-on or standalone tool designed for small e-commerce businesses, freelancers, and independent sellers. The core concept is to provide a granular, replayable transaction log that goes beyond typical accounting software. Imagine a user needs to understand why their profit margin dipped significantly on a specific product over a period. Traditional software shows the final figures. ChronoSolver, much like Leonard Shelby piecing together his past, allows the user to 'rewind' their transaction history for that product. It would work by integrating with e-commerce platforms (via APIs or even by parsing downloaded CSVs initially, keeping it low-cost) and actively scraping or monitoring product pricing and sales data. When a transaction occurs, it's not just recorded as a sale; it's timestamped and linked to a specific product price at that exact moment, along with any associated discounts, shipping costs, or platform fees. The 'Memento' element comes in with a visualized timeline. Users can select a date range, a specific product, or even a customer, and the software presents a chronological playback of all relevant financial events. This allows for:

1. Price Audit & Anomaly Detection: Users can visually identify instances where product prices were changed unexpectedly (either by themselves, a competitor, or the platform) that directly impacted sales and profitability. This is the 'E-Commerce Pricing' scraper inspiration – not to scrape external competitors, but to analyze the -internal- pricing history against actual sales.
2. Transaction Reconstruction: For complex returns, disputes, or audits, users can reconstruct the exact sequence of events for a particular sale, seeing the initial price, any subsequent adjustments, and the final amount paid.
3. Profit Margin Analysis Over Time: By visualizing pricing and sales alongside each other chronologically, users can gain deep insights into how pricing strategies affect profit margins on a micro-level.

Implementation: Initially, this could be a browser extension that intercepts and logs data from specific e-commerce platforms the user frequents. Alternatively, it could be a desktop application that processes exported transaction data from platforms like Shopify, Etsy, or Amazon Seller Central. The 'Memento' visualization could be a timeline interface with draggable markers. The niche aspect is the focus on granular, temporal transaction reconstruction for e-commerce sellers, which is often overlooked by broader accounting software. The low-cost implementation comes from starting with data parsing and potentially using open-source charting libraries. High earning potential lies in offering this as a premium add-on for accounting suites, a standalone SaaS for e-commerce businesses, or even as a specialized auditing service for high-volume sellers.
