Antes de empezar: qué necesitas

Prepara la fuente de stock, el mapeo SKU y la promesa de fulfillment antes de conectar FBA con Shopify. La mayoría de problemas vienen de ownership poco claro, no de la conexión.

SKU o códigos coincidentes

Confirma que el SKU de Amazon, SKU de Shopify, EAN o código apunta al mismo producto físico y variante.

Acceso al informe de stock FBA

Conoce qué cantidades FBA son vendibles, reservadas, inbound, dañadas o bloqueadas antes de publicar en Shopify.

Reglas de stock de ChannelDock

Asegúrate de poder editar buffers, reservas y ajustes de sync en Stock Level Sincronizar.

Consejo: empieza con tus SKU FBA más vendidos y productos Shopify con la misma promesa de fulfillment. Los setups híbridos con almacén propio van en otro flujo como rastrear stock FBA y de almacén.

Paso a paso: sincronizar inventario FBA con Shopify

Usa este flujo cuando Shopify deba vender desde disponibilidad Amazon FBA sin exponer unidades reservadas, retrasadas o prometidas en otro canal.

Elegir la fuente de stock por SKU

Decide si Shopify usará solo FBA, solo tu almacén o un pool vendible combinado. Documenta la decisión por SKU antes de automatizar.

Error común: combining FBA and warehouse stock without checking which location can actually fulfill Shopify orders on time.

Relacionar identificadores de Amazon y Shopify

Mapear Amazon SKUs, Shopify SKUs, EANs and variant options so the same product cannot split into two stock records. Use exact variant mapping for size, color and bundle components.

Error común: matching only the parent product while child variants still use different SKU logic.

Quitar unidades reservadas y no vendibles

Subtract Amazon reserved stock, pending orders, damaged units, inbound stock that is not yet available and any safety stock you do not want Shopify to sell.

Error común: syncing total FBA quantity instead of the available quantity that can ship today.

Configurar buffers Shopify para productos rápidos

Add a small buffer for products with high velocity, slow FBA report updates or sales on multiple channels. Buffers keep the last risky units away from Shopify.

Error común: using zero buffer on SKUs that can sell several units between two sync runs.

Conectar la regla de sync en ChannelDock

Use ChannelDock Stock Level Sincronizar to publish the calculated sellable quantity to Shopify and other connected channels.

Error común: letting Shopify, Amazon and a spreadsheet all edit the same stock field independently.

Probar con un grupo pequeño de SKU

Pick 10-20 products, compare Amazon FBA, ChannelDock and Shopify quantities, then place a test order or simulate reservations before expanding the rule.

Error común: activating the full catalog before checking edge cases such as bundles, returns and stock held in transfer.

Monitorear excepciones a diario en el lanzamiento

Review SKUs where Shopify quantity differs from the expected FBA sellable stock. Investigate cancellations, returns, FC transfers, FBA receiving delays and manual corrections.

Error común: fixing the visible Shopify number without solving the source mismatch.

El bucle de sync FBA a Shopify

A reliable sync does not push every FBA unit to Shopify. It starts with FBA availability, removes risk, then publishes only the sellable number.

The best Shopify stock number is not “what Amazon says exists”. It is what your business is willing and able to sell right now.

Errores comunes de sync FBA-Shopify

  • Publishing total FBA quantity instead of sellable availability after reservations.
  • Forgetting that Amazon reserved stock can include pending orders, FC transfers and processing units.
  • Letting Shopify sell FBA units while Amazon, bol.com or another marketplace can still claim them.
  • Ignoring bundles where one FBA component limits the Shopify parent product.
  • Not testing returns and cancelled orders before syncing the full catalog.

Manual FBA exports vs. ChannelDock Stock Level Sincronizar

A manual export can update Shopify once. ChannelDock is built for the repeated operational decisions that happen after every order, reservation and stock correction.

Sin ChannelDock

  • Teams download FBA reports and update Shopify quantities by hand.
  • Reserved, inbound and damaged units are easy to overlook in spreadsheets.
  • Shopify oversells when Amazon, marketplace orders or returns change stock faster than the manual update cycle.

Con ChannelDock

  • Stock Level Sincronizar calculates safer availability from one operational stock view.
  • Buffers, reservations and channel rules help protect the last risky units.
  • Shopify receives updated sellable stock while related workflows such as overselling prevention stay aligned.

FAQ de inventario Amazon FBA y Shopify

Mapear Amazon and Shopify SKUs, subtract reserved and non-sellable FBA units, apply a buffer, then publish the resulting sellable quantity to Shopify with a stock sync rule.

Use available stock, not total stock. Total FBA stock can include reserved, damaged, inbound or processing units that should not be sold on Shopify yet.

Yes, but keep the stock pools separate until the fulfillment promise is clear. Combine only the quantities that can actually ship for Shopify orders within the promised time.

Sincronizar after meaningful stock changes such as order imports, reservations, returns, FBA receiving and manual corrections. Fast-moving SKUs need tighter monitoring and stronger buffers.

Use one trusted stock source, subtract reservations, set channel-specific buffers and avoid letting both platforms independently edit the same availability number.

Bundles can work if the sync uses component availability. The parent product should be limited by the component with the lowest sellable quantity across FBA and other locations.
