What Kiabi Marketplace is
Mirakl’s July 2022 announcement called it the “1ère marketplace prêt-à-porter omnicanale dédiée à la famille” (the first omnichannel ready-to-wear marketplace for families)3. It was built with Mirakl, and testing began in April 2022, with a wider ramp-up planned from the back-to-school season3.
For the 2022 back-to-school season Kiabi planned 35 sellers and 35,000 product references, and it aimed for more than 200,000 products and 500 sellers by 20253.
In March 2026 Kiabi launched the marketplace on kiabi.es, called France fully operational and said Italy was being added2. RetailDetail reported that “Spain and Italy are first in line, with other countries to follow”5. A marketplace also runs on kiabi.be, and it delivers only to Belgium4.
Who can sell on Kiabi Marketplace
Kiabi’s platform terms open the marketplace to “tout professionnel” (any professional) that signs up to its services1. You register with your company name, registered office, VAT number, contact details and trade-register entry1. Kiabi can refuse or suspend a registration if this information is untrue, incomplete or out of date1.
In 2022 Kiabi described the marketplace as selective: sellers had to share its values, and it targeted national brands, local designers and niche or responsible makers3. Their offers had to compete on quality, price and style, with excellent customer service3.
If you are based outside France. Check these points:
- Kiabi’s Belgian terms set no location rule, but you still need a VAT number and a trade-register entry to register1.
- Kiabi says it will add new sellers progressively as the marketplace rolls out to Spain and Italy2.
- Products sold on kiabi.be must comply with EU law4.
- For products covered by extended producer responsibility (EPR) in France, a seller not established there has had to appoint an EPR representative in France since 10 July 2026, unless a platform established in France ensures EPR compliance for those products6.
Fees and payouts
Kiabi does not publish its fees. Its platform terms refer to separate seller service terms (CGS), which govern its services to sellers and are supplied when you register1.
Kiabi commits to transfer your funds no later than the day after the business day it receives them1. Customer payments are held in a segregated account at a third-party bank1.
Your Kiabi prices come from the same Mirakl margin rules as your other storefronts, with the fee percentage set separately for Kiabi.
How to apply
Register your company
Enter your company name, registered office, VAT number, contact details and trade-register entry1.
Read the seller service terms
Kiabi supplies its seller service terms (CGS), which govern its services to sellers, at the start of registration1. Ask about fees before you accept them.
Listing rules and how offers compete
On kiabi.be, each product sheet must show the item’s essential characteristics and legally required details, such as repairability, environmental qualities and sorting rules4. When you act as a distributor, you must also take back used products of the same kind free of charge4.
The Belgian conditions exclude large appliances, large furniture and “tous les produits accessoires et déguisements type arme / guerre / signes religieux” (all accessories and costumes of a weapon, war or religious-symbol type)4.
Kiabi says it “n’exerce aucun contrôle préalable sur les offres des Vendeurs” (does not check sellers’ offers in advance)1. Any report of illegal content leads to the product being unpublished as a precaution1. Where several sellers offer the same item, a “Buy box” and a “Choice Box” decide which seller is featured1.
Delivery and returns
You handle shipping, customer service and incidents, and you set your own delivery methods and costs2. On kiabi.es, product pages name you under “Vendido por” (sold by)2.
Kiabi’s Belgian conditions add these rules4:
- Preparation times shown at checkout exclude weekends and public holidays.
- You may split an order into several shipments at no extra cost to the customer.
- You must use the delivery method the customer chose.
- Customers have 14 days from receipt to withdraw, and they pay the direct cost of returning the item4.
- You pay return costs if the item was wrong, faulty or damaged when unpacked.
- Returns come to your address, never to Kiabi or a store.
- If delivery is late, the customer may cancel after a reasonable grace period and be fully refunded within 14 days4.

- 18 March 2026: Kiabi announced its Spanish marketplace, with Italy next2.
- At that launch, Kiabi Iberia’s Mirko Peloso called the marketplace “un ecosistema abierto y omnicanal al servicio de las familias” (an open, omnichannel ecosystem serving families)2.
