Where each fits

Rithum is a powerful enterprise channel and dropship network — and it sits in front of an operating system like ours. Here’s where each fits.

System vs. network

The operating system behind the channels

Rithum connects you to 420+ marketplaces and retail channels and runs dropship, private marketplaces, and retail media. Endless runs the business behind those channels: inventory, orders, PIM, and demand planning on one source of truth, with native EDI built in. Rithum distributes; Endless operates.

Runs the whole back office
Native EDI, inventory, orders, and planning
One source of truth end to end

One source of truth

Clean, live data feeding your channels

Rithum syncs listings, inventory, and orders across channels, but it isn’t your system of record — you still need a platform running accurate inventory and orders behind it. Endless is that source of truth, feeding Rithum live data so channel listings and dropship stay accurate, not stale.

Endless is the system of record
Live inventory and orders, not stale syncs
Feeds your channels accurate data

White-glove vs. enterprise rollout

Live in hours, run for you

Rithum is enterprise and quote-based, with implementation complexity that can exclude smaller teams. Endless is transparent-priced and white-glove — we get you live in hours and run the back office for you, on one platform from $1M to $500M+ GMV.

Transparent, published pricing
White-glove onboarding, live in hours
One platform from SMB to enterprise

Agentic depth

Agents across the back office, not just the channel

Rithum optimizes channels and listings, and its Cadeera AI maps catalogs. Endless extends agents across the whole back office on one data model — reordering, routing, EDI, and reconciliation — not just channel optimization.

Autonomy beyond the channel layer
One crew of agents, one data model
Reorders, routing, EDI, reconciliation

When to use each

An honest read on where each shines — plenty of brands run both.

Reach for Endless when…

You want one operating system running inventory, orders, PIM, planning, and EDI
You want a single source of truth feeding your channels and dropship programs
You want transparent pricing and to go live in hours, not a long enterprise rollout
You want agents that run the whole back office, not just channel optimization

Reach for Rithum when…

You need to list and sell across 420+ marketplaces and retail channels
You’re running enterprise dropship or private-marketplace programs at scale
You want consolidated retail media and advertising across marketplaces
You’re an enterprise with the resources for a larger implementation

These solve different parts of multi-channel commerce and pair naturally. Rithum is the enterprise network that connects you to marketplaces, retailers, and dropship programs; Endless is the operating system that runs inventory, orders, planning, and native EDI on one source of truth behind them. Run Endless as your system of record and connect to channels through Rithum.

The proof is in the numbers

Endless agents run the back office, so the work gets done — and shows up in the numbers. Here’s what that looks like in practice.

Endless + Rithum FAQ

What’s the main difference between Endless and Rithum?

Rithum is an enterprise commerce-operations network — the 2023 union of CommerceHub, ChannelAdvisor, and Dsco — connecting 40,000+ brands and retailers to 420+ marketplaces and retail channels, with dropship, private marketplaces, marketplace listings, and retail media. Endless is a brand-level commerce operating system that runs inventory, orders, PIM, demand planning, and native EDI on one source of truth. Rithum is the network in front of your channels; Endless is the operating system behind them.

Can Endless and Rithum work together?

Yes — they work at different layers. Endless serves as the brand-level system of record for inventory, orders, catalog, and planning, while Rithum connects that data to marketplaces, retailers, and dropship programs. Run Endless behind the scenes and use Rithum as the channel network in front of them.

How does dropship work across Endless and Rithum?

Rithum (including its Dsco dropship platform) is the rail that connects you to retailers’ dropship and private-marketplace programs. Endless keeps the inventory, orders, and catalog behind that rail accurate on one source of truth, so the listings and stock Rithum distributes reflect what’s actually available.

How does pricing compare?

Rithum is enterprise and quote-based (including monthly GMV fees for dropship), and its implementation complexity can exclude smaller merchants. Endless publishes transparent pricing for the whole operating system and is built to scale on one platform from $1M to $500M+ GMV.

Is Dsco part of Rithum?

Yes. Dsco is Rithum’s dropship platform — CommerceHub acquired Dsco in 2020, and CommerceHub, ChannelAdvisor, and Dsco rebranded as Rithum in 2023. Endless can serve as the source of truth feeding Dsco/Rithum dropship programs.

How do the AI capabilities compare?

Rithum’s AI (including Cadeera) focuses on catalog mapping, listings, and channel optimization. Endless extends agents across the whole back office on one source of truth — reordering, routing, EDI, and reconciliation — not just the channel layer.
