Looking for a Rithum (ChannelAdvisor) alternative?
InfiPlex charges a flat, published rate from $49.99/month — no revenue share, ever. Rithum's own G2 reviews describe being "nickel and dimed despite having a revenue share agreement," and its Trustpilot page sits at a 2.2/5 TrustScore, with one reviewer reporting being billed for over 700 cancelled orders.
Rithum (ChannelAdvisor)

- EDI transactions billed individually, stacking further
- Multi-year contracts, reported as hard to exit
- Support reportedly "fallen off a cliff" since the CommerceHub merger
What changes
- Flat published pricing — no revenue share, ever
- Most integrations connect in days
- Month-to-month available, no multi-year lock-in
- US-based support, consistent since day one
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 reviewers 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 reported resistance to renegotiation at renewal. And the support decline tracks specifically to the CommerceHub merger, with reviewers who used the platform both before and after describing email-only support and multi-day response times that didn't exist previously.
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 in recent reviews.
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 in reported experiences.
One takes a cut of your revenue. One doesn't.
Four concrete differences, not marketing language
No revenue share, ever
Before: 2-3% of revenue on top of feesFlat monthly pricing — $49.99, $499.99, or $999.99 — published in full, no matter how much revenue moves through the platform.
No per-message EDI fees
Before: EDI transactions billed individuallyThe EDI-to-API bridge is included, not metered by every purchase order, acknowledgment, or invoice message.
Days to launch, not a quarter
Before: onboarding commonly runs months, billed throughoutLink your channels, map SKUs once, set routing rules. Most existing integrations are live within days.
No multi-year lock-in
Before: multi-year contracts, steep exit penaltiesBasic Starter is month-to-month. Growth plans require just a 3-month commitment.

[Name, Title] — [Company]Questions people ask before switching
How much does Rithum (ChannelAdvisor) actually cost?
Rithum doesn't publish pricing. Reported costs commonly start above $2,000/mo, plus a 2-3% revenue share, plus per-transaction EDI fees on top — and some sellers report total costs rising four to sevenfold 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 is commonly reported to take 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's reported as 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?
You connect your existing channels, map SKUs once, and set routing rules — most customers are live within days, without needing to wait out a multi-year contract term first.
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.

No email, no sales call to see pricing — and never a cut of your revenue.
