If you’re running a multichannel ecommerce business on Rithum, the platform formerly known as ChannelAdvisor, you already know what it does well: marketplace integrations, listing syndication, and order routing. But you probably also know what it costs you. Revenue share pricing, long-term contracts, and a support experience that doesn’t always match the price tag.
You’re not alone. We talk to sellers every week who want to leave but stay because of one thing: the fear of migration. What happens to your product data? Your listings? Your inventory sync? Will you lose your Buy Box while switching over?
This guide walks you through exactly how to switch from Rithum to a platform like StoreAutomator, step by step, with zero downtime and no lost data.
Why Sellers Are Looking for ChannelAdvisor Alternatives
The rebrand from ChannelAdvisor to Rithum changed the name, but not the pricing model. Sellers searching for channeladvisor alternatives or channeladvisor competitors typically share the same frustrations:
- Revenue share pricing that grows with your sales; the more successful you are, the more you pay. At $5M in annual revenue, even a small percentage adds up fast.
- Long-term contracts that lock you in for 12–24 months, even when your needs change or support quality drops.
- Complex onboarding and slow support, enterprise-grade complexity without enterprise-grade responsiveness.
- Limited flexibility in how you map product data across channels, especially for sellers with large catalogs or custom attribute requirements.
The result? Sellers stay on Rithum not because it’s the best fit, but because switching feels risky. Let’s fix that.
What Actually Happens During a Platform Migration
The biggest misconception about switching multichannel platforms is that it requires a hard cutover; one day you’re on Rithum, the next day you’re on something else, and everything in between is chaos. That’s not how it works.
A well-managed migration runs in parallel. Your existing Rithum setup stays live and active while the new platform is configured, tested, and validated alongside it. You only switch over when you’re confident everything works.
Here’s the typical timeline:
- Data export and mapping (Week 1–2): Your product catalog, inventory levels, and order history are exported from Rithum. The new platform maps your data fields — titles, descriptions, images, custom attributes, pricing rules — to its own structure. StoreAutomator supports XML, CSV, and API imports, so whatever format Rithum gives you, it works.
- Channel configuration (Week 2–3): Each marketplace connection (Amazon, Walmart, eBay, Shopify, Target+, etc.) is set up in the new platform with channel-specific data mapping. This is where StoreAutomator’s category templates and override capabilities matter — your listings are optimized per channel, not just copied across.
- Parallel testing (Week 3–4): Both systems run simultaneously. Inventory syncs are validated. Orders flow correctly. You and your team verify that everything matches before any cutover.
- Go live (Week 4–5): Once testing is complete, you switch your live marketplace connections to the new platform. Rithum is deactivated. Your sales never stop.
What You Keep (and What You Don’t Lose)
The data that matters most to multichannel sellers — your product catalog, listing content, pricing rules, and sales history — comes with you. Here’s what transfers:
- Full product catalog with all attributes, variations, images, and custom fields
- Marketplace listings- your live Amazon ASINs, Walmart listings, and eBay items stay untouched. The new platform connects to existing listings; it doesn’t recreate them.
- Inventory levels and sync rules - real-time inventory management picks up exactly where Rithum left off
- Order management workflows - including 3PL integrations, drop shipping rules, and fulfillment routing
- Pricing and repricing rules- dynamic pricing configurations can be recreated in the new platform
-
What you won’t lose: your Buy Box position, your seller ratings, your listing rankings, or your sales velocity. These live on the marketplace side, not on Rithum’s side. Switching your backend platform doesn’t affect them.

How to Start the Switch
Most sellers we work with start the conversation 60–90 days before their renewal window. If you’re seriously considering a move, request a free demo.
At the end of the demo, you will receive:
- A clear migration roadmap with timelines specific to your catalog size and channel mix
- An honest evaluation of whether StoreAutomator is the right fit (not every seller needs to switch)
- A cost comparison showing exactly what you’d save by moving to flat monthly pricing
- Zero obligation - you walk away with the roadmap, whether or not you move forward
Switching your multichannel platform is a big decision. But staying on one that’s eating into your margins is a bigger one. The sellers who make the move don’t regret the switch; they regret not doing it sooner.
