Amazon FBA Integration - Automate Amazon Fulfillment

Fulfilled by Amazon means Amazon stores, picks, packs, and ships your orders, but the moment you sell on more than just Amazon, FBA stops being a self-contained system and becomes one more inventory pool you have to keep in sync with everything else. Base turns Amazon FBA from a separate operational silo into part of your day-to-day multichannel workflow: orders, stock visibility, inbound shipments, listing management, repricing, returns, and invoicing in one panel.

That gap between “what Amazon shows” and “what your other channels think you have” is where most of the pain lives. A sale on Amazon that doesn't reflect fast enough on your webstore, or FBA stock nobody's tracking outside Seller Central, is exactly what causes oversells and cancelled orders elsewhere. Base doesn't replace Amazon as the source of truth for FBA stock, Amazon still owns that, but it pulls FBA data into the same view as your other sales and stock processes, so it stops being a blind spot.

What the integration handles

Orders, routed by fulfillment model

Base imports Amazon orders and automatically distinguishes FBA from merchant-fulfilled orders, so you can run different processing and automation flows for each. Dedicated Amazon conditions, including FBA and Prime, make that separation native rather than something someone sorts manually.

FBA stock, visible alongside everything else

FBA stock data can be imported into Base and viewed together with your other sales channels and warehouses. Base closes the gap where FBA stock sits invisible to the rest of your operation while everything else runs through Base.

Inbound shipments to Amazon, managed inside Base

Base includes a full workflow for sending stock to Amazon Fulfillment Centers: create inbound shipments, assign products to cartons, complete packing and transport details, and track shipment progress, without moving the work back to Seller Central.

Bulk fulfillment control for listings

Amazon offers, including FBA offers, can be imported into Base and filtered by fulfillment model. Fulfillment type can be switched between merchant-fulfilled and FBA in bulk, so changing logistics strategy doesn't mean editing listings one by one.

Pricing that knows the difference between fulfillment models

Repricing tools support comparison against FBA offers only, merchant-fulfilled (FBM) offers only, or both, so pricing strategy can actually account for which fulfillment model you're competing against, not just the lowest price on the listing.

Returns and invoicing without a separate system

FBA return information imports into Base, keeping order history in one place instead of split between Amazon and wherever else you track returns. Where supported, invoices can be forwarded or uploaded to Amazon according to your configuration.

One system across multiple Amazon marketplaces

If you sell on multiple Amazon marketplaces, they're managed from the same Base account instead of one login per region. If your FBA stock sold on Amazon accounts is shared across multiple countries in the same region, you can stop or start sync for a specific marketplace with just a few clicks.

Built for local tax and invoicing too

The Amazon FBA integration also supports selected regional programs and invoicing scenarios, including OnSite in Brazil, VCS in Europe, and SEFAZ-related flows for Brazil. These are not separate integrations. They are regional scenarios supported within the same Amazon FBA integration.

Take it further with Amazon MCF

Amazon Multi-Channel Fulfillment is a separate Amazon service: it lets you use your existing FBA inventory to fulfill orders placed on channels other than Amazon, your own store, other marketplaces, wherever you sell. It's a natural pairing with this integration, since you're already managing FBA and your other channels in the same place. Base has a dedicated MCF integration for that side of things.
