JTL is an all-in-one platform for building and running multi-channel commerce systems. It provides merchants with a single place to manage products, inventory, orders, and fulfillment across online stores, marketplaces, and internal systems. JTL Cloud builds on top of the platform by exposing APIs, webhooks, and an app platform. This is where you build integrations, automate workflows, and extend the platform with custom applications.

​
How the Platform is Structured

The platform is made up of a few core components. They can be used independently or combined depending on what you’re building.
ComponentDescription
JTL-WawiThe ERP at the center of the platform: products, inventory, orders, and customers all live here.
JTL HubThe API layer, webhooks, and infrastructure you’ll use to build cloud apps and integrations.
App ShellThe container that hosts your app’s UI. It handles layout, navigation, and communication with the rest of the platform.
App StoreWhere merchants go to discover and install apps.
ERP CloudThe cloud-based interface where your installed app actually runs.
Marketplace ChannelsTools and APIs for connecting to external marketplaces like Amazon and eBay.
Since all of these components share the same underlying data through Wawi, you don’t have to worry about syncing state between them yourself.

​
What You Can Build

JTL Cloud gives you the tools to extend the platform in several directions:
  • Cloud apps that plug directly into the JTL platform
  • Marketplace integrations that sync products, orders, and inventory with external channels
  • ERP integrations that automate internal business workflows
  • Event-driven systems that react to changes via webhooks
You can mix and match these to fit whatever commerce workflow you’re working with.

​
What Makes JTL Different

JTL is designed around multi-channel commerce at scale, and that shapes how everything works, from how data flows to how integrations are structured.
  • ERP-first design: Wawi is the single source of truth. Products, inventory, and orders always originate there, which means your integrations don’t have to reconcile conflicting data from multiple sources.
  • Multi-channel from the ground up: The platform is built to keep data in sync across stores, marketplaces, and internal systems, so you’re not bolting on multi-channel support after the fact.
  • Built for real operations: Workflows include retries, conflict handling, and batch processing, the kind of things you need when data has to move reliably at scale.
  • Extensible without forking: You can build custom integrations, cloud apps, and automation workflows that plug into the platform without touching the core system.
