I need a robust, future-proof way to keep my PrestaShop catalogue perfectly aligned with MercadoLibre, Amazon, AliExpress and Shein—and to push new listings to any of those marketplaces from a single screen. At the moment I update everything manually, so overselling and price mismatches have become a real risk. Here is what I’m aiming for: • One source of truth: PrestaShop remains the master database (unless you suggest a smarter hub-and-spoke tool that still lets me stay in full control). • Automatic stock and price synchronisation across the four marketplaces; near real-time would be ideal, but I’m open to the solution you believe is most stable. • The ability to create or bulk-publish products—including images, descriptions, variations and marketplace-specific attributes—without leaving the central dashboard. • Clear logs or dashboards so I can see what updated, when, and where. If something fails to post, I should know immediately. • A straightforward way to map categories, shipping templates and other marketplace requirements once, then reuse them. • Clean hand-over: full documentation and a brief walk-through so my team can run the system confidently after you finish. I’m comfortable with plug-ins, custom middleware, or even moving to a specialised SaaS connector—whichever gives the best mix of reliability, scalability, and cost-effectiveness. If APIs (PrestaShop WebService, Amazon SP-API, MercadoLibre API, AliExpress Open Platform, Shein) are your daily playground, I’d love to hear your proposal and timeline.
