Marketplace integration

A consumer electronics retailer in Alicante sells on its own site, on Amazon.es and on PcComponentes, and wants to add El Corte Inglés and Carrefour. Right now it updates stock on each channel by hand twice a day. That holds up until the day the last three pairs of headphones sell on Amazon while still showing on PcComponentes, a fourth order lands and has to be cancelled. Marketplaces track every seller's cancellation rate and dispatch times, and a bad patch means less visibility or a suspended account. Integration takes care of the tedious part: one shared stock figure, prices worked out per channel, all orders in one place and tracking numbers sent back on time.

What falls within the scope of this service

Listing products is the easy bit. The real work lies in sharing out stock, setting prices that still leave a margin and handling orders and returns without retyping.

Pin down the details with one of our engineers

Typical channels

Amazon.es and the other European Amazon stores, El Corte Inglés, PcComponentes, Carrefour, Miravia, Fnac, eBay and AliExpress. Each with its own categories, mandatory attributes and shipping rules.

Feed tool or direct API

Channable or Lengow if you want to start quickly on a subscription. A direct link to the marketplace API when volume or business rules justify it.

Listings per channel

EAN, brand, attributes, images and copy shaped to what each marketplace demands. What Amazon accepts, PcComponentes may reject, and every category has its own fields.

Prices with commission inside

Per-channel rules that factor in commission, delivery cost and promotions, with a floor price below which nothing is published.

Central order handling

Orders from every channel arrive in your shop or ERP, are picked in the same workflow and invoiced with the right details.

Dispatch and tracking

The tracking number is sent back to the marketplace before the cut-off, because on-time dispatch counts towards the seller rating.

Returns

A return logged on Amazon.es or El Corte Inglés goes back into stock and prepares the credit note, without waiting for the warehouse to send an email.

How the engagement unfolds, one stage at a time

The first marketplace takes the most effort because of listings and attributes. Later ones move faster, since stock and orders are already wired up.

Product matching

Each SKU is tied to its offer on every channel by EAN and internal reference. Doubtful pairs are checked one at a time.

Stock rules

We decide whether every channel draws on the same pool or whether some units are ring-fenced for one channel during campaigns such as Black Friday.

Full test order

Purchase, stock reservation, invoice, label, tracking, return and credit note, end to end.

Upkeep

Marketplaces change their requirements and APIs often. We follow their notices and adapt the integration before the deadline.

Watch out during big campaigns. On Black Friday or back-to-school, a marketplace can multiply orders for one SKU tenfold within an hour. If stock syncs every fifteen minutes, that gap is enough to sell units you no longer have. For campaigns we shorten the interval, raise the safety buffer and ring-fence units per channel.

Common questions

With one channel and a small range, the Amazon dashboard is enough. Once your own shop and two marketplaces run side by side, stock needs adjusting several times a day and a human slip is only a matter of time. Integration usually pays for itself through the cancellations it prevents and the hours it frees.

Channable and Lengow come with ready-made connections to most marketplaces and charge a monthly fee. They are a good way to begin. A direct link makes sense when your pricing or stock rules will not fit the tool, when you run several warehouses, or when the fee already exceeds what your own integration would cost.

Stock held in Amazon's warehouses is managed separately and must not be mixed with your own. We model it as an extra warehouse in the ERP, with its own ins and outs, so the books and the inventory show where every unit sits.

Sales to consumers in other member states are usually taxed at destination through the One Stop Shop (OSS). Technically, each order must reach the ERP with the correct country and rate. The tax decision is for your company and its adviser.
