InfiPlex vs. Rithum (ChannelAdvisor)

Looking for a Rithum (ChannelAdvisor) alternative?

InfiPlex charges a flat, published rate from $49.99/month — no revenue share, ever. Rithum does not publish pricing; sellers describe a base fee above $2,000 a month, a 2-3% revenue share, and per-transaction EDI charges stacked as separate line items, including billing on cancelled orders.

VS
The pattern

What the pattern actually looks like

The pricing structure compounds in a specific way: the base monthly fee, the revenue share, and per-transaction EDI charges are all separate line items, and sellers describe being billed for cancelled orders that generated no revenue at all, a cost with no corresponding sale to offset it. On contracts, the pattern is multi-year terms with resistance to renegotiation at renewal. And the support decline tracks specifically to the CommerceHub merger, with sellers who used the platform both before and after describing email-only support and multi-day response times that did not exist previously.

Before you commit

Three questions worth asking Rithum directly

What's the true all-in cost at your volume?

Model the base fee, the revenue share, and per-transaction EDI charges together at your actual order volume — not just the headline monthly minimum.

Are cancelled orders billed?

Ask specifically and in writing; this is one of the more concrete, repeated complaints from sellers.

What's the exit process, contractually?

Ask for the specific termination clause and notice period before signing, not after — multi-year lock-in is a recurring theme.

What sets InfiPlex apart

Inventory sync isn't outsourced, it's the foundation

Rithum has no native inventory management and depends on data fed in from an outside system. In InfiPlex, inventory sync isn't bolted on afterward, it's what everything else runs on.

1

Inventory sync is native

49 named sources, ERPs, 3PLs, storefronts, or direct entry, feed one combined pool natively, with nothing external required to keep it accurate.

2

Drop-ship documents, handled directly

Purchase order acceptance, ship notices, and invoicing for EDI trading partners are handled inside InfiPlex, delivered through a normal REST API, not a separate system to maintain.

3

One pool feeds the listings, too

The same inventory that prevents overselling is what every connected channel, marketplace or EDI retailer, reads from, no separate feed to keep synchronized.

Rithum has no MCP server; the InfiPlex one is live on every instance. Every InfiPlex instance runs a native MCP server, so Claude, ChatGPT through Codex, Cursor, or any MCP client can search orders, explain why an order routed to a warehouse, check inventory across warehouses, read the shop log, record tracking, and set prices in plain English, with a preview before anything channel-visible changes. It is included with API access, and connecting takes about five minutes. Not sure what that means for security? The plain-English answer, or watch a demo.

FAQ

Questions people ask before switching

How much does Rithum (ChannelAdvisor) actually cost?

Rithum doesn't publish pricing. Costs commonly start above $2,000/mo, plus a 2-3% revenue share, plus per-transaction EDI fees on top, and sellers describe totals rising sharply since the merger into Rithum.

Does InfiPlex take a percentage of my revenue like Rithum?

No. InfiPlex charges a flat published rate — $49.99, $499.99, or $999.99/mo depending on tier — with no revenue share and no per-transaction EDI fees, regardless of sales volume.

How long does Rithum onboarding take compared to InfiPlex?

Rithum onboarding commonly takes months, with billing continuing the whole time. Most InfiPlex customers connect existing integrations in days.

Is InfiPlex a good fit for the same businesses that use Rithum?

Rithum is generally positioned for large enterprise brands doing $50M+ in annual GMV, with a cost structure that is uneconomical below that scale. InfiPlex serves brands and sellers from their first sale through 50,000+ monthly orders on Growth Enterprise, with published pricing at every tier below that.

Does InfiPlex offer advertising or retail-media tools like Rithum?

No — InfiPlex focuses on order management, inventory sync, and fulfillment routing rather than retail media advertising. If advertising optimization is a core need alongside marketplace management, that's worth weighing against InfiPlex's focus.

What does the actual switch away from Rithum involve?

InfiPlex runs in parallel with Rithum while channels move one at a time, listings stay live on each marketplace, and most connections are live within days, so you do not wait out a multi-year term before starting. The Moving off ChannelAdvisor guide walks through the full cutover, including the CommerceHub dropship side and contract timing.

Is InfiPlex billed based on order volume like Rithum?

No — InfiPlex's flat monthly rate doesn't scale with revenue or order volume the way a percentage-of-revenue model does. Higher-volume sellers pay the same published rate as lower-volume ones on the same tier.

Does InfiPlex bill for cancelled orders?

InfiPlex's published pricing is based on plan tier and included order allotments, not billed per individual transaction — so a cancelled order isn't a separate line item the way it can be under a per-transaction EDI fee structure.

Why do revenue-share pricing models create the complaints they do?

When a vendor's fee scales with a seller's revenue rather than the actual cost of running the platform, the seller's growth and the vendor's bill grow together regardless of whether the underlying service cost has changed — a structural mismatch that shows up repeatedly in pricing complaints.
