When Stripe is cheaper and when IC+ is cheaper
Stripe's 2.9% + 30¢ is priced as a one-size-fits-all. It's designed to be profitable across every merchant category — which means it's overpriced for most merchants above $50k/mo and underpriced for a few edge cases (very small tickets, B2B cards-on-file, international-heavy).
The cross-over point where IC+ beats Stripe is typically at $30-50k/mo of card volume for ecommerce with clean ticket sizes. Below that, Stripe usually wins because IC+ contracts carry monthly minimums ($25-100), statement fees ($10-40), and per-transaction fixed fees that compound on low volume.
Above $100k/mo the Stripe premium is usually 40-100 bps of pure margin that the merchant gets back with IC+. Above $500k/mo the gap is typically 60-120 bps. At $2M+/mo, Stripe is leaving 80-150 bps on the table relative to a well-negotiated IC+ contract or an Adyen/Worldpay enterprise deal.
Why Stripe is sticky anyway
Most merchants stay on Stripe above the cross-over point because Stripe's infrastructure is excellent. APIs are clean, docs are complete, webhooks are reliable, the dashboard is fast. Migrating off Stripe to a lower-cost IC+ acquirer means rewriting integrations, retraining ops, and accepting a UX downgrade. Many operators (correctly) decide the price premium is worth the infrastructure.
But the decision should be conscious. If you're paying $40k/mo in processing fees on Stripe and could pay $24k/mo on IC+, that's $192k/yr of decision to make — not a default to accept.
What the calculator captures
Volume, ticket, international mix, subscription billing usage, chargeback count. These five inputs cover 95% of the cost variance between Stripe and IC+ for ecommerce merchants.
Stripe math: 2.9% + 30¢ on domestic, 2.9% + 1.5% + 30¢ on international. Billing adds 0.5% if used. Chargebacks are $15 each. Radar ($0.05/authorized) and Instant Payouts (1.5%) are not included unless you enable them.
IC+ math: blended CNP interchange around 1.85%, network assessments 0.16%, processor markup scaled to your volume (40 bps at $100k/mo, 20 bps at $500k/mo, 12 bps at $2M/mo), per-transaction fees 7-10¢, cross-border 1% added on international volume, chargeback $15 each.
What's missing from this model
Reserves — IC+ contracts sometimes carry reserves where Stripe does not (and vice versa for high-risk). Our reserve cost calculator handles that separately.
Dispute handling — Stripe's dispute workflow is instrumented. Legacy acquirers make you log in to a separate portal. Real cost but hard to quantify.
Fraud tools — Stripe Radar is best-in-class at $0.05/authorized. Replacing it on IC+ means standalone fraud tools (Sift, Kount, Signifyd) at 15-50 bps.
Payout timing — Stripe pays in 2 days standard. Most IC+ acquirers pay next-day. Real cash-flow impact; our payout timing calendar shows the math.
Payment method breadth — Stripe supports ~40 global methods out of box. Traditional IC+ acquirers often support 5-10. If you need Klarna, Afterpay, OXXO, iDEAL, etc., Stripe is hard to replace.
When to keep Stripe
- Under $50k/mo volume — math favors flat-rate
- Heavy global payment method mix — Stripe's breadth is hard to replicate
- Engineering team too small to maintain a second acquirer integration
- Marketplace or Connect use case — Stripe Connect is uniquely good
- Brand/product that Stripe classifies as low-risk; don't tempt a risk review
When to move to IC+
- Above $500k/mo — the premium becomes material
- Consistent card mix and simple flows
- High-risk vertical where Stripe is tolerating you but at premium pricing
- Multi-brand operator who wants a single parent MID
- B2B-heavy where Level 2/Level 3 data can drop interchange 40-80 bps (IC+ exposes this; flat-rate buries it)
The multi-brand move
For multi-brand operators running 5+ Stripe accounts, the consolidation math is compelling. 5 Stripe accounts at 2.9% + 30¢ = 5 separate flat-rate contracts with 5 separate fraud exposures. Consolidating on a parent MID via multiflow at 5.5-7.5% (our tier pricing on gross + interchange passthrough) plus our setup fee typically compresses 40-80 bps versus the sum of 5 Stripe contracts — plus eliminates the risk of a single Stripe review taking down one of 5 brands.
FAQ
Does Stripe ever offer IC+ pricing?
Yes — Stripe's Custom tier for $500k/mo+ merchants includes IC+. You have to ask for it explicitly. Not volunteered.
Will Stripe match an IC+ quote?
Sometimes, if your volume justifies. Bring a competing quote with specifics (acquirer, markup, fixed fees). Stripe's pricing team can move 20-60 bps on a qualified merchant.
What's the typical IC+ contract term?
1-3 years with automatic renewal. Early termination fees are standard ($250-1000). Negotiate the fee and the auto-renew clause.
Is switching worth the integration pain below $200k/mo?
Rarely. Below $200k/mo the annual savings of 40-80 bps is $10-20k. Integration work for a second acquirer typically costs 40-80 engineering hours. Net positive but small; most merchants don't bother.
Do IC+ processors require a long-term commitment?
Most do. Month-to-month IC+ contracts exist but typically carry higher markup as the processor amortizes customer acquisition over shorter tenure.
