Catalog Syndication to Mercado Libre and Amazon Mexico

Where syndication actually breaks: The order side, not the listing side. A listing that publishes and then oversells costs more than one that never published: on Mercado Libre a cancellation for missing stock moves the reputation thermometer, and a seller sitting at yellow loses the exposure the catalog was published to win. So the first work is stock policy and delivery promise per channel, and the listing build follows it. Mercado Libre: The distinction that decides the outcome is publicación versus catálogo listing. Winning the buy box on a catalog listing turns on price, reputation, Full availability and delivery promise, not on description quality, which is why this is an operations engagement wearing a feed engagement's clothes. Ficha técnica completeness per category drives listing quality, and variations belong modelled as attribute combinations. The most common thing we undo is one separate publicación per size where a single variation set was the correct structure, splitting the item's history and its reviews across five listings. Amazon Mexico, Meta, TikTok Shop: Flat files or SP-API listings, browse node mapping decided deliberately rather than guessed from keywords, GTIN exemption filed where private label needs it, and monitoring for suppressed listings, which fail silently and will not appear in your feed tool's success count. On Meta, content_id has to match the product IDs the pixel and Conversions API send, exactly, or the catalog cannot attribute anything; set-level segmentation then follows margin band rather than category. TikTok Shop Mexico brings its own category tree and shipping templates and does not accept a Google-shaped feed. Stock and price policy per channel: Buffers set per channel instead of one global number, because a channel shipping from a marketplace warehouse carries different risk than one shipping from yours. Price floors computed after commission, fulfilment and expected return rate, per channel, so the floor genuinely differs between them and the feed enforces it rather than a person remembering to. Where a SKU's contribution goes negative on a channel after those costs, it does not go on that channel, and you get the arithmetic rather than an opinion. What you receive: A channel matrix stating which SKUs go where and why, attribute mapping per marketplace, the stock buffer and floor price logic implemented in your feed platform, listing quality tracked per channel, and an exception report showing what did not publish and what it is waiting on. That report is the deliverable people underestimate; it is what turns syndication from a launch into a process. Not included: Photography and A+ content. Marketplace account registration, RFC and invoicing setup. Customer service and post-sale handling, which stay with you and which the channels grade you on. Advertising inside marketplace ad platforms. Warehouse and fulfilment operations. Translation of product copy beyond Spanish and English. Who this is not for: Brands that cannot hold the delivery SLA of the channels they want to be on, because the reputation damage outlasts the revenue. Catalogs where the request is maximum SKU coverage as an objective in itself; coverage is not a goal, contribution is. Sellers who want marketplace listings live before their stock data is trustworthy, which is the sequence that produces cancellations, and we will not build in that order.
