The marketplace wave reaches Spanish retail

A major European pet-supplies retailer has just opened its marketplace to Spanish sellers, adding thousands of new references to its catalogue and turning the country into its third marketplace market in Europe after France and Germany. The move is a useful signal for anyone running an online shop in Catalonia or elsewhere in Spain: the platform model is no longer the exclusive territory of the global giants. Specialist verticals are adopting it too, and that reshapes the competitive map for small and mid-sized merchants.

For a shop in Lleida, Barcelona, Tarragona or Girona, the question is no longer whether marketplaces matter, but how to position yourself when a well-known brand in your sector invites third-party sellers onto its own storefront.

Why a specialist retailer becomes a platform

The logic behind this kind of expansion is straightforward. A retailer with a loyal customer base and strong organic traffic can widen its assortment without carrying all the stock risk itself. External sellers bring categories the retailer does not want to buy directly, and the retailer monetises the traffic it already has.

From the seller's side, the appeal is equally clear:

Access to an existing audience instead of building one from zero, market by market.
Lower entry cost than opening a physical presence or a localised online shop in each country.
Validation of demand for niche products before committing to a full commercial operation.

What the German rollout of this same marketplace shows is that catalogue breadth grows quickly once third parties join, and that new categories, including fresh and frozen goods, can become significant sales drivers. That is worth noting: marketplaces are moving into logistics-heavy categories that were traditionally the preserve of specialist shops.

The trap: renting visibility instead of owning it

Marketplaces are an excellent acquisition channel, but they are a channel you do not control. The listing rules, the commission structure, the visibility algorithm and the customer relationship all belong to someone else. A merchant who builds their entire online business on a third-party platform is, in practice, a tenant.

This is where a well-built own online shop still earns its place. Your ecommerce site is the only asset where you set the margins, own the customer data, define the buying journey and decide how the brand looks and speaks. In a market where marketplaces are multiplying, the shops that thrive are the ones that treat the platform as an extra shop window and their own store as the headquarters.

What a shop that actually sells looks like

Selling online is not about having a catalogue online. It is about removing friction at every step between landing and paying. In our experience building tienda online projects for Spanish merchants, the difference between a shop that converts and one that merely exists usually comes down to a handful of decisions:

The right platform for the job. PrestaShop suits catalogues with complex variants, tiered pricing and B2B logic; WooCommerce fits brands that want content, SEO and store under one roof. Choosing badly costs more later than choosing well now.
Conversion optimisation as an ongoing discipline, not a one-off redesign: checkout friction, shipping costs shown early, product pages that answer real questions, mobile performance.
Integration with the rest of the stack: stock, invoicing, logistics and analytics talking to each other so nobody reconciles spreadsheets by hand.
GDPR-compliant data handling from the first cookie banner to the newsletter consent, which matters more than ever when you also sell through partners.

Coexistence, not competition

The realistic strategy for most Spanish merchants is hybrid. Use marketplaces to test new regions and reach buyers who already trust a large platform, and use your own comercio electrónico site to build margin, loyalty and brand. Keep pricing coherent across channels, avoid cannibalising your own listings, and make sure stock synchronisation is solid enough that you never oversell.

If a marketplace in your sector opens in Spain, read it as a map of where demand is heading, not as a threat. The merchants who win are those with a well-engineered online shop behind them, ready to capture the customers who prefer to buy direct.
