FinixA82
Payment Processor · Software platforms, marketplaces and vertical SaaS embedding payments, and direct merchants processing well…
Overview
Finix inverts the usual pricing model. Instead of a percentage markup on every sale, it charges a monthly subscription starting at $250 and takes 0% markup on interchange and card network fees, adding a flat $0.08 per card-present transaction and $0.15 per card-not-present transaction. Amex is 0.30%. ACH is 1% per same-day entry with a $1 minimum and a $10 cap. Disputes are $30. That structure is genuinely better than a percentage markup once volume is high enough for a fixed fee to be trivial, and genuinely worse below that point. Finix has been a card-network-certified processor since May 2023 rather than a reseller, with direct connections to Visa, Mastercard, Amex and Discover through banking partner Pathward. The caution is that its public merchant record is thin and mixed: a strong Capterra score from a small sample, an essentially empty BBB file, and complaints from platform partners about underwriting and loss allocation.
Best for: Software platforms, marketplaces and vertical SaaS embedding payments, and direct merchants processing well over $1m a year who want interchange passed through at cost with the processor's margin isolated in a subscription line they can see.
Strengths
- + 0% markup on interchange and card network fees, with the processor's margin isolated in a subscription line rather than buried in a percentage
- + Flat per-transaction pricing — $0.08 card-present, $0.15 card-not-present — means the cost of a $2,000 sale is the same as a $20 one
- + A card-network-certified processor since May 2023 with direct Visa, Mastercard, Amex and Discover connections, not a reseller layered on another platform
- + Full fee schedule published, including the awkward ones — disputes, ACH returns, account updater, tokenization, Plaid
- + Well capitalised and active: a $75m Series C in October 2024 led by Acrew Capital, with Citi Ventures joining, and new product and partner announcements through mid-2026
- + Rated 4.7 out of 5 across 42 verified reviews on Capterra, where reviewers repeatedly single out hands-on implementation support
Trade-offs
- – The $250 monthly floor makes Finix poor value below roughly $1m a year — that is $3,000 annually before you process anything
- – No contract term, notice period or termination fee is published anywhere on the pricing pages
- – Settlement timing is not published; payout schedules are described as customisable rather than quoted
- – The public merchant record is thin — 42 Capterra reviews and a BBB profile with a single review, miscategorised under 'Farm Management Software'
- – Negative merchant reports exist but are hard to corroborate: a single one-star BBB review from a platform, and an anonymously operated complaint website alleging weak merchant underwriting. The one federal case on record, a 2025 contract dispute, was dismissed within two months
- – Built for platforms first. A single-location merchant wanting terminals, POS software and a support line will find the product and the pricing aimed past them
Fees in detail
- Online rate: Interchange and card network fees at 0% markup, plus $0.15 per card-not-present transaction, on top of the monthly subscription
- International: American Express is charged at 0.30% per transaction
- Disputes: $$30 per card or ACH dispute
