Integration of online listings to marketplaces (e.g., Etsy, eBay)

Purpose

1.1. Automate the process of syncing antique furniture listings from an internal system or point of sale (POS) onto multiple online marketplaces, ensuring pricing, descriptions, images, and stock quantities are uniformly updated to drive reach, reduce manual data entry, and accelerate multi-channel sales strategies.
1.2. Ensure real-time listing status (active, sold, revised) is immediately reflected across all channels.
1.3. Centralize management of incoming marketplace orders and messages for operational visibility and efficiency.
1.4. Synchronize inventory to prevent overselling and ensure compliance with each marketplace’s unique policy requirements.
1.5. Enable automatic promotion and cross-posting of high-value or featured antiques to social commerce platforms and marketplaces.
