OmniMerkez

Turkish sellers list the same products on several marketplaces and store platforms. OmniMerkez manages them from one place and is honest about it: a capability matrix generated from the code shows what each channel’s API supports and how much of it OmniMerkez implements. An iOS app handles packing, stock counts and adding products by photo.

The Problem

Selling on several channels means updating stock and prices in several places — and overselling when one is missed. Integrators often promise features the channel’s API does not actually offer.

The Solution

Adapters built from each channel’s official documentation, a queue for every sync job, a single stock model, and a public capability matrix so sellers see exactly what works per channel.
