Why sellers switch from Rithum
Profit per order, not an estimate
Rilk matches Amazon, Walmart and eBay settlements back to each order automatically, so fees, refunds and re-rates show up against the order they belong to.
Serials and regrading built in
Every unit keeps its serial from receiving to sale. Regrade a return, log the repair cost, and relist it under the right SKU with the original cost attached.
No professional-services contract
Need a channel Rilk doesn't connect yet? On Ultimate we usually build it ourselves — no development fee, no hourly billing.
Free for your first 500 orders a month. Pro from $999/mo.
The details
ChannelAdvisor is now Rithum
+−
In December 2023, ChannelAdvisor, CommerceHub and Dsco combined under one name, Rithum. If you're searching for ChannelAdvisor, that's the name you'll find now.
Start free, work your own orders today
+−
Connect Amazon, Walmart, eBay, Shopify or WooCommerce and your orders land in one screen. Buy labels on your own UPS, FedEx, USPS and DHL accounts and rate-shop every order. The first 500 orders a month are free, with no card and no sales call. Pro is 14 days free when you want inventory, purchase orders and reports.
Amazon and Walmart Buy Shipping on the order screen
+−
Buy the label at the marketplace's own rates right from the order, without switching tools. Rilk went through multiple rounds of Amazon review, including the Appstore listing review and a data security assessment under Amazon's Data Protection Policy, and Amazon granted Rilk its restricted Direct-to-Consumer Shipping role on 24 August 2026.
Profit per order, from what the marketplace actually paid
+−
On Amazon, Walmart and eBay, Rilk matches each settlement back to its orders automatically, so the fees on an order are what the marketplace charged, not an estimate. Label re-rates, refunds and adjustments show up against the order they belong to. On other channels you import the payout file and Rilk does the matching.
Retailer channels and EDI on Ultimate
+−
Selling to retailers like Home Depot or Lowe's? Ultimate adds retailers on Mirakl, SPS Commerce and retailer EDI, with their orders in the same screen as your marketplace orders.
Serials, grading and returns in one flow
+−
Every unit keeps its serial from receiving to sale. Regrade a return, log the repair cost against that serial and relist it under the right SKU, with the original cost following the unit. Returns received go straight back into sellable stock in the right bin.
Purchase orders with the real unit cost
+−
Freight, duty and the other costs on a purchase order are spread across every unit on it, so your cost per unit is right the day the shipment is received, and so is your profit.

- Serial tracking, regrading and returns
- Purchase orders with landed cost, and FBA inbound

New channels without a professional services contract

Switching from ChannelAdvisor
