Quick signals

Complexity
High
Requires platform PayFac registration, compliance expertise, and 6-12 month implementation - justified only at significant scale
Common upgrade trigger
Stripe Connect per-merchant fees exceed $50K/year - PayFac economics become favorable
When it gets expensive
Monthly platform fee ($2,000-$5,000) fixed cost before merchant volume revenue

What this product actually is

Finix is payment infrastructure enabling software platforms to become payment facilitators (PayFacs) and own payment economics. Captures merchant payment revenue share vs paying Stripe Connect fees.

Pricing behavior (not a price list)

These points describe when users typically pay more, what actions trigger upgrades, and the mechanics of how costs escalate.

Actions that trigger upgrades

  • Stripe Connect per-merchant fees exceed $50K/year - PayFac economics become favorable
  • Platform reaches 500 merchants - Finix minimum requirements met
  • Payment revenue opportunity exceeds $1M/year - ownership justifies complexity
  • Need complete white-label control - Stripe branding limitations become blocker
  • Merchant underwriting requirements specific - Finix custom risk rules available

When costs usually spike

  • Monthly platform fee ($2,000-$5,000) fixed cost before merchant volume revenue
  • PayFac registration costs $50K-$150K in legal, compliance, and setup fees
  • Platform liable for merchant chargebacks - reserve requirements can lock up capital
  • Merchant onboarding approval rate lower than Stripe - platform bears risk assessment
  • Contract commitments typically 24-36 months vs Stripe Connect's pay-as-you-go
  • International expansion requires separate PayFac registrations per region

Plans and variants (structural only)

Grouped by type to show structure, not to rank or recommend specific SKUs.

Plans

  • Platform - $2,000-$5,000/month platform fee + per-transaction - Minimum 500 merchants or $100M GMV

Enterprise

  • PayFac-as-a-Service - Custom revenue share (20-40 bps) - Full white-label, 6-12 month implementation
  • Enterprise - Fully custom pricing and terms - Large platforms with 1,000+ merchants

Costs and limitations

Common limits

  • Requires significant commitment - platform must be registered PayFac (regulatory burden)
  • Minimum revenue requirements - typically need $100M+ GMV or 500+ merchants
  • Platform assumes merchant risk and chargeback liability (Stripe Connect doesn't)
  • Setup complexity high - 6-12 month implementation vs Stripe Connect's weeks
  • Monthly platform fees ($2,000-$5,000) before merchant volume considered
  • Smaller payment coverage than Stripe - fewer alternative payment methods

What breaks first

  • Merchant growth slower than projected - fixed monthly fees erode margins
  • Chargeback rates spike - platform absorbs losses Stripe Connect would shield
  • Compliance burden (PCI, KYC, AML) exceeds internal operational capacity
  • International expansion needs blocked by PayFac registration requirements
  • Developer resources insufficient for ongoing payment infrastructure maintenance

Decision checklist

Use these checks to validate fit for Finix before you commit to an architecture or contract.

  • Developer Experience vs Simplicity: Assess internal technical capabilities and API integration requirements
  • Transparent Pricing vs Cost Variability: Analyze transaction mix (card types, international %, currency conversions)
  • Upgrade trigger: Stripe Connect per-merchant fees exceed $50K/year - PayFac economics become favorable
  • What breaks first: Merchant growth slower than projected - fixed monthly fees erode margins

Implementation & evaluation notes

These are the practical "gotchas" and questions that usually decide whether Finix fits your team and workflow.

Implementation gotchas

  • Platform liable for merchant chargebacks - reserve requirements can lock up capital
  • Own payment facilitator status → Regulatory compliance and operational overhead
  • Setup complexity high - 6-12 month implementation vs Stripe Connect's weeks
  • Developer experience less polished than Stripe's documentation and SDKs
  • Platform responsible for compliance (PCI, KYC, AML) - operational overhead

Questions to ask before you buy

  • Which actions or usage metrics trigger an upgrade (e.g., Stripe Connect per-merchant fees exceed $50K/year - PayFac economics become favorable)?
  • Under what usage shape do costs or limits show up first (e.g., Monthly platform fee ($2,000-$5,000) fixed cost before merchant volume revenue)?
  • What breaks first in production (e.g., Merchant growth slower than projected - fixed monthly fees erode margins) — and what is the workaround?
  • Validate: Developer Experience vs Simplicity: Assess internal technical capabilities and API integration requirements
  • Validate: Transparent Pricing vs Cost Variability: Analyze transaction mix (card types, international %, currency conversions)

Fit assessment

Good fit if…

  • Established software platforms with 500+ merchants processing payments
  • Vertical SaaS companies where payments are 20%+ of revenue opportunity
  • Platforms processing $100M+ GMV annually where economics justify PayFac ownership
  • Software companies wanting to capture 20-40 bps revenue share per merchant
  • Businesses needing complete white-label control over merchant payment experience
  • Platforms where Stripe Connect per-merchant fees erode margins at scale

Poor fit if…

  • Early-stage platforms with <500 merchants - Finix minimums not met
  • Software companies unwilling to assume merchant risk and chargeback liability
  • Teams lacking compliance expertise (PCI, KYC, AML) - operational burden high
  • Need fast launch (<6 months) - use Stripe Connect instead
  • International payments priority - Finix coverage limited vs Stripe's global reach
  • Platform GMV under $50M/year - economics don't justify PayFac complexity

Trade-offs

Every design choice has a cost. Here are the explicit trade-offs:

  • Earn 20-40 bps revenue share → Assume merchant risk and chargeback liability
  • Complete white-label control → 6-12 month implementation and $50K-$150K setup
  • Better unit economics at scale → Fixed monthly fees ($2K-$5K) and minimums (500 merchants)
  • Direct sponsor bank relationships → Smaller payment method coverage than Stripe
  • Own payment facilitator status → Regulatory compliance and operational overhead

Common alternatives people evaluate next

These are common “next shortlists” — same tier, step-down, step-sideways, or step-up — with a quick reason why.

  1. Stripe (Connect) — Step-down / platform payments
    Evaluated when platforms want embedded payments without assuming full PayFac compliance and risk ownership.
  2. Adyen — Step-sideways / enterprise payments
    Considered by larger merchants optimizing enterprise payment infrastructure rather than becoming a PayFac.
  3. Checkout.com — Step-sideways / enterprise payments
    Compared when the priority is payment optimization and enterprise acquiring, not PayFac economics.
