SellMate

Automatically syncs product data (title, description, price, images, SKU) across multiple e-commerce platforms (Amazon, eBay, Shopify, Etsy, etc.) from a single source of truth. Uses API connectors to each marketplace's product management endpoints, with conflict resolution logic to handle platform-specific field constraints and formatting requirements. Detects inventory changes in real-time and propagates updates across all connected channels within minutes.

Analyzes product titles, descriptions, and metadata against marketplace search algorithms and competitor listings to suggest keyword improvements, title rewrites, and description enhancements. Uses NLP/embedding models to identify high-performing keywords in category, calculates search volume and competition metrics, and recommends A/B test variants. Integrates with platform-specific ranking factors (e.g., Amazon A9 algorithm, eBay search relevance) to prioritize optimizations with highest conversion impact.

Maintains a unified inventory ledger across all connected sales channels, automatically decrementing stock counts when items sell on any platform and preventing overselling. Implements real-time inventory sync via webhooks or polling to detect sales events, calculates available-to-sell quantities accounting for reserved/pending orders, and triggers low-stock alerts. Supports multi-warehouse scenarios with location-based inventory allocation and reorder point automation.

Collects sales, traffic, and conversion metrics from all connected marketplaces and consolidates into unified dashboards with cross-channel performance comparisons. Calculates KPIs (revenue by channel, conversion rate, average order value, customer acquisition cost) and generates trend reports showing performance over time. Implements data warehouse pattern to normalize disparate marketplace APIs into common schema, enabling SQL-like queries across channels.

Analyzes purchase history and product attributes to identify frequently co-purchased items and suggests product bundles or cross-sell recommendations. Uses collaborative filtering or content-based recommendation algorithms to rank products by likelihood of purchase together, calculates bundle profitability (margin impact), and generates bundle descriptions. Integrates with listing optimization to promote bundles across channels with dynamic pricing.

Monitors product listings against marketplace policies (prohibited items, restricted categories, content guidelines) and flags violations before they result in account suspension or delisting. Implements rule-based policy engine with marketplace-specific rule sets (Amazon Brand Registry, eBay authenticity, Shopify restricted products), scans listing content for policy violations, and suggests remediation steps. Tracks policy changes from each marketplace and alerts sellers to required updates.

Analyzes competitor pricing, demand signals, and inventory levels to recommend dynamic price adjustments across channels. Uses algorithmic pricing engine that factors in cost, margin targets, competitor prices (via web scraping or API), and inventory age to calculate optimal prices. Implements price rules (e.g., 'always undercut Amazon by 5%', 'increase price if inventory < 5 units') and applies changes automatically or with seller approval.
