Ramp vs Brex vs Airbase 2026: The Hidden Fee Ledger

Last verified: October 5, 2026.

All three spend-management platforms advertise a free tier, and all three mean something different by it. Ramp's "free" just grew a $0.59 per-transaction ACH fee and a variable cashback rate. Brex's "free" sits behind a $50,000 minimum cash balance and a Capital One subsidiary's risk appetite. Airbase's pricing is not published at all — and hasn't been since Paylocity paid roughly $325 million for it. "Free" in corporate cards is a marketing word; the ledger is what matters.

This comparison runs the full 2026 ledger: the feature-by-feature table, the fee changes that landed this year, the same workload priced across all three platforms, and the stage-and-geography logic that should make the decision for you.

The Head-to-Head, Feature by Feature

The table's quiet tell is the cashback row: three completely different reward philosophies. Ramp prices simplicity with an underwriting-set rate, Brex prices engagement with a category multiplier, Airbase prices predictability at 1.5%. None of them are comparable without knowing your spend mix — which is the point.

Ramp 2026: The Free Tier Grew Fine Print

Two changes landed on Ramp this year. First, cashback moved from a flat 1.5% to a variable 0–1.5% set per business under Ramp's own underwriting — Ramp told NerdWallet in June 2026 that the rate is assessed per customer, which means your marketing budget now determines your rewards rate. Second, a $0.59 per-transaction fee arrived on standard ACH payments starting June 1, 2026 — the first meaningful fee in the Free tier's history, applied to new contracts with a three-month grace period for existing accounts.

What survived intact: the card itself stays free with no annual fee, expense management remains free at any team size, and bill pay still carries three-way matching with accounting sync. Ramp Plus at $15 per user per month (plus a platform fee that scales with team size) adds HRIS sync, advanced approval chains, and custom spend policies. The strategic read: Ramp is monetizing the transaction layer rather than the software layer — which favors light-ACH users and quietly re-prices invoice-heavy teams.

Brex 2026: The $50K Door and the Capital One Effect

Brex's transformation is structural. Now operating as a Capital One subsidiary, it explicitly repositioned for VC-backed growth-stage companies — and the proof is the new qualification floor: at least $50,000 in cash reserves to access the corporate card and platform, a world away from the pre-2022 any-startup-welcome posture. The full product also requires VC backing.

What the door buys: a rewards ladder that beats flat cashback for travel-heavy companies — 7x on rideshare, 4x on travel, 3x on restaurants, 2x on software — plus the Brex Business Account earning roughly 5% APY on idle cash, making it a finance platform rather than a card. Brex Premium runs $12 per user per month and adds multi-currency global payments, an AI budgeting layer, and tier-based platform fees. The international advantage is real: card issuing and spend across 70+ countries with native multi-currency rails, where Ramp remains US-focused and Airbase is effectively US-only under Paylocity.

Airbase 2026: Paylocity-Owned, Mid-Market Priced

Airbase was acquired by HR-and-payroll platform Paylocity for roughly $325 million, closing in October 2024 — a deal widely misreported elsewhere as a Maxio acquisition. Under Paylocity it continues as a standalone spend-management product with custom pricing for mid-market and enterprise buyers, generally $500–$2,000 per month.

The price buys the deepest AP automation in this comparison: full purchase-order-to-payment workflow, vendor management, bill payments, expense reimbursements, and corporate cards inside one unified approval system. For companies at $5M–$50M ARR where finance teams burn 20+ hours a week on manual AP processing, that depth is not a luxury — it is the product. The 1.5% US-spend cashback is a pleasant footnote rather than the pitch.

The Same Workload, Three Bills

Abstract pricing turns concrete fast. Run a 20-person team processing 500 invoices a month through each platform:

The Ramp-versus-Brex gap at this size is $720 a year — meaningful, not decisive, and likely decided by the rewards mix rather than the sticker. The decisive row is the third one: against legacy AP incumbents, the modern platforms are an order of magnitude cheaper, which is the real competitive story of 2026. At the other end of the scale, a 50-person company at $5M+ ARR needing full AP automation lands at Airbase's $12,000–$24,000 a year — and the AP-labor savings alone typically cover it.

The Stage-and-Geography Decision

Three variables settle the choice. Stage: seed-to-Series-B companies fit Ramp's free core; Series-A-to-growth companies with real funding histories fit Brex (which requires the VC backing anyway); Series B+ companies above $5M ARR with AP-heavy operations fit Airbase. Geography: any meaningful international footprint makes Brex the default, since its 70+ country rails have no real competitor in this trio. Spend mix: travel-and-rideshare-heavy companies earn more from Brex's multipliers; invoice-heavy companies feel Ramp's $0.59 ACH fee most; procurement-heavy companies need Airbase's PO workflow full stop.

Run those three filters and the decision usually makes itself before any demo is booked.

What to Watch From Here

Two corporate stories will move this comparison. The Airbase-Paylocity integration roadmap: when payroll and spend management unify into one SKU, the all-in pricing structure — and the $500–$2,000 custom band — could shift materially. And Capital One's integration of Brex: subsidiary status has implications for the credit model, card-network positioning, and the enterprise sales motion that Brex's growth-stage customers never see coming. The platforms are consolidating into larger parents on all sides; the fees will follow the ownership.
