I’m looking to centralize and automate the way my catalog moves between PrestaShop and each marketplace where I sell—MercadoLibre, Amazon, AliExpress and Shein. Right now every stock change or new product means repetitive manual work and, inevitably, out-of-sync quantities. My ideal flow is simple: I update (or create) a product once inside PrestaShop and the change instantly—or at least reliably on a schedule—hits every channel, complete with price, images, variations and attributes. I’m open to the best method to achieve this. If a native PrestaShop module or connector can cover all four marketplaces, great; if it makes more sense to introduce a middleware layer (e.g. a PIM, ERP, or a custom API bridge) I’m happy to hear that, too. What matters is gaining full control, reducing overselling and being able to push listings out from one place instead of four. Scope of work • Assess my current PrestaShop install along with marketplace API requirements. • Propose the architecture (module, third-party SaaS, custom integration, or hybrid). • Build or configure the connectors so stock, price and product data flow both ways. • Enable direct product publishing from PrestaShop, including bulk listing when possible. • Provide clear documentation and a short hand-over session so I can manage the system confidently. Acceptance criteria – SKUs share the same real-time (or scheduled) quantity on every platform. – New or edited products in PrestaShop propagate to each marketplace without manual duplication. – Fail-safe logging and alerts are in place for sync errors. If you’ve integrated PrestaShop with any of these marketplaces before—or have a clever alternative that keeps everything in lockstep—let’s talk.
