Why this happens

Technical root cause

Stock is shared across sales channels but synchronized on a schedule. Between syncs the same unit can be sold twice, and negative or stale quantities are pushed to the marketplace.

Mercado Libre Marketplace reports it as Stock insuficiente o desfasaje en sincronización and applies: Order cancellations and seller reputation damage.

Native CMS friction

  • Shopify

    Multi-location inventory needs aggregation, and webhook delays let concurrent orders overlap.

  • VTEX

    Reserved stock in logistics is not always deducted from the quantity exported to marketplaces.

  • WooCommerce

    Cron-driven stock updates can lag well behind real orders on busy stores.

Fixing it manually

  1. 1

    Compare published quantities against real available stock for the top sellers.

  2. 2

    Apply a safety buffer so the marketplace never sees your last units.

  3. 3

    Increase sync frequency for fast-moving SKUs.

  4. 4

    Pause listings whose source stock cannot be resolved rather than guessing.

The IRONFEED automated solution

One rule, applied to every product on every export. No spreadsheets, no re-uploads.

Rule syntax
IF available_quantity <= safety_buffer
  SET available_quantity = 0
  ELSE SET available_quantity = available_quantity - safety_buffer

Run automatic linter checks before Mercado Libre Marketplace crawls your feed. IRONFEED validates every export against the channel spec, so this error is caught in Feed Review instead of in your channel dashboard.

Moneda no coincide con el site local de Mercado Libre

Regional sellers keep one base currency internally and expect conversion at publish time. The integration passes the base amount through, and locale formatting adds separators the API does not accept.

Combinación de variantes no válida para la categoría

Store catalogs allow arbitrary option names such as material, flavour or pack size. Mercado Libre rejects axes its category does not define, and it also rejects two variants that resolve to the same combination.

Mismatched value [availability]

Stock is the fastest-moving attribute in any catalog. Scheduled exports lag behind sales, and backorder or pre-order states have no direct equivalent in the storefront's boolean stock flag.
