Open New Supply Ecosystems, Not Just Individual Seller Integrations.

GSS helps a marketplace enter or deepen a market by bringing supply, brands, sellers, localization, local operations and fulfillment — as one program rather than one seller at a time.

How Supply Is Built

The marketplace growth problem

One Integration at a Time Does Not Build a Category.

A marketplace entering a new country — or trying to deepen one — needs categories filled with the right brands, at the right price, available fast. Recruiting and integrating sellers one by one rarely gets there.

Supply gaps: Categories with too few brands, too little depth or the wrong price points for the market.
Localization gaps: Good products held back by content, language, compliance or pricing not ready for the market.
Operating gaps: Sellers who can list but cannot keep stock, service and delivery at the marketplace’s standard.

Supply ecosystem creation

Supply Brought In as a Program.

GSS sources and organises supply across its network, then runs it on the marketplace as one managed ecosystem.

Brand & seller sourcing: Brands and sellers from the Türkiye manufacturing and brand network, plus European and global brands in the GSS network.
Category building: Categories assembled around the gaps the marketplace wants to close, not around whoever applies first.
Multi-party supply programs: Supply, retail and quick-commerce partners combined where a category needs more than one party — as in the SOL–Jahez program.

Onboarding & catalog localization

From Signed Supplier to Live, Localized Catalog.

Onboarding is run as a pipeline, so the marketplace sees categories filling rather than a queue of individual sellers.

01
Qualify
Brands and sellers assessed for assortment fit, pricing, supply reliability and compliance with the market.
02
Set up
Commercial terms, the operating model and — where needed — import and invoicing roles agreed.
03
Localize the catalog
Titles, attributes, images, language and compliance data prepared to the marketplace’s standards.
04
List & price
Listings launched with a price position and promotion plan for the category.
05
Operate
Stock, orders, service and performance run to the marketplace’s service levels.
06
Review
Category performance reviewed with the marketplace team, and the next supply wave planned.

Cross-border-to-local progression

Launch Cross-Border. Graduate to Local Inventory.

New supply can go live quickly from outside the market. The categories that prove themselves move into local inventory.

01
Cross-border launch
Selected assortment sold into the market from existing stock.
02
Proven demand
Sell-through, price and service data show which categories work.
03
Local inventory
Winning assortment moves into market for faster delivery.
04
Local operations
Deeper ranges, local promotions and full in-market operations.

Fulfillment & operations

Supply That Meets the Marketplace’s Standard.

The supply program includes the operations behind it, so the marketplace does not inherit sellers it has to manage one by one.

Fulfillment coordination: Cross-border and local fulfillment arranged to the marketplace’s delivery promise.
Operating model: Stock, pricing, content and customer operations run for the supply GSS brings.
Channel connectivity: Catalog, order and stock flows connected to the marketplace through the GSS commerce layer.
