Solution / Multi-Channel Commerce
One product system.
Multiple channels.
Expand into new marketplaces without turning every channel into a separate copy of your catalog.
The problem
Adding another marketplace should not mean rebuilding the business's product knowledge.
Etsy, eBay, Amazon, Shopify, and other channels represent products differently. Their categories, identifiers, variation models, field limits, and publishing behavior vary.
The underlying product does not.
A multi-channel system keeps product truth centralized and translates it into the representation each destination needs.
Canonical first
Define the product once. Translate it at the channel boundary.
Product identity, variants, dimensions, pricing inputs, imagery, and other business-owned information live in one authoritative model. Channel adapters then convert that data into Etsy, eBay, Amazon, or storefront-specific structures.

Publishing behavior
A shared product model does not mean sending the same payload everywhere. It means marketplace differences stay isolated instead of becoming duplicated product data.
Live solution
Decal Design Center uses one workflow to prepare products for different marketplace structures.
The DDC Listing Engine creates structured product data once and uses channel-specific branches for Etsy and eBay, with Amazon integration being developed around the same canonical model.
