Brex vs Airbase — which fits a 50-500 employee finance team?

Card-first teams that live on employee spend, travel, and fast-moving budgets fit Brex: published plans run from a $0 Essentials tier to $12/user/month Premium to custom Enterprise (as of October 2026 — check current pricing). Procure-to-pay teams whose week is supplier invoices, purchase orders, and approval chains fit Airbase, which prices by quote for mid-market companies. The fork is where your money moves: cards and reimbursements point to Brex; AP and procurement point to Airbase.

How do Brex and Airbase pricing models differ?

Brex publishes its rate card: Essentials free, Premium $12/user/month, Enterprise custom, plus a custom-priced Smart Card procurement edition (vendor-published as of October 2026; check current pricing). Airbase is quote-only for its mid-market procure-to-pay suite — no public rates — and now sits inside Paylocity's finance platform, so pricing conversations route through Paylocity sales. A per-user card platform and a custom-quoted P2P suite rarely land in the same price band; model your user count and invoice volume separately.

Is Airbase still a standalone product?

Airbase was acquired by Paylocity and is now positioned as the spend-management layer of Paylocity for Finance — airbase.com routes to a Paylocity landing page as of October 2026. Existing customers keep their portals and contacts, but new buyers should evaluate Airbase as part of Paylocity's HCM-plus-finance bundle, and check current packaging before committing.

Do Brex and Airbase both handle bill pay and reimbursements?

Yes, with different centers of gravity. Brex includes automated bill pay and reimbursements on every published plan (vendor-published; check current terms), but its depth is cards, travel, and budget controls. Airbase treats AP as the core: invoice capture, PO matching, and layered approval chains, with cards and reimbursements attached to the procure-to-pay flow. Either can do both jobs; neither does both equally well.

Brex vs Airbase (2027): Spend Management Compared

The short answer: Brex is a card platform that grew into spend management — free-to-$12/user/month published pricing (check current terms), global cards, travel, and AI-assisted controls, strongest for venture-backed and fast-growing companies that spend through cards. Airbase is procure-to-pay software that grew cards on later — quote-only, mid-market, built around invoice capture, PO matching, and approval chains, and now part of Paylocity. For 50-500 employee finance teams: card-heavy spend picks Brex, invoice-heavy AP picks Airbase.

These two meet in the middle of the spend-management market from opposite directions, and the comparison is really a question about your company's spend DNA. This comparison is editorial research based on vendor documentation and published pricing pages, not hands-on testing; prices and packaging change, so verify current terms before deciding.

Pricing: published rate card vs custom quote#

Brex publishes its plans (as of October 2026 — check current pricing): Essentials free with global cards, bill pay, reimbursements, and accounting integrations; Premium $12/user/month adding multi-entity support, custom expense policies, advanced approvals, and HRIS integrations; Enterprise custom with unlimited entities and named support; plus a custom-priced Smart Card edition for procurement-heavy card programs.

Airbase does not publish rates. It sells a custom-quoted procure-to-pay suite aimed at mid-market companies, and since the Paylocity acquisition it is packaged as the spend-management layer of Paylocity for Finance — so the quote conversation now includes HCM context (check current packaging with Paylocity sales). Expect the pricing shape of mid-market P2P software: platform fee, invoice and payment volume bands, module add-ons.

The shape: at 50 employees spending mostly on cards, Brex Premium prices in the hundreds per month and starts free to trial; a mid-market AP suite quoted for invoice volume will usually land higher and needs a sales cycle to even see the number.

Features: where each one is deepest#

Brex's depth is the card and the controls around it: unlimited global cards accepted in 210+ countries and territories, local-currency cards in 50+ countries, AI-powered spend rules, dynamic approval chains, live budgets, integrated travel booking, and a business account with ACH, wires, and reverse-wire payroll (vendor-published; check current terms). Bill pay and reimbursements are included, but they orbit the card.

Airbase's depth is the procure-to-pay chain: invoice capture and coding, PO matching, multi-layer approval workflows with policy enforcement, and spend that gets approved before it happens — cards and reimbursements are payment methods inside that flow rather than the product itself. The catalog view of Airbase is unchanged: strong controls and approvals for finance teams, good for complex multi-entity needs, with heavier setup than a card-first tool.

Both sync to the major GLs (Brex lists NetSuite and tailored accounting integrations with AI mapping; Airbase is built for mid-market ERP stacks) — confirm your specific ERP connector during evaluation.

Use cases: which company fits which#

VC-backed startup, 50-150 employees, spend is cards and travel? Brex — the free Essentials tier gets you live in a day, Premium adds the policy and multi-entity controls at a published $12/user/month (check current pricing).
150-500 employees with a controller and a real AP function — supplier invoices, POs, accruals? Airbase — procure-to-pay discipline is the point, and the Paylocity bundle matters if HCM consolidation appeals.
Multi-entity, international card spend? Brex Premium or Enterprise — local-currency cards in 50+ countries and multi-entity support are published plan features.
Procurement-heavy spend that needs approval before commitment? Airbase — pre-spend control is the design center; Brex's Smart Card edition covers the card slice of it.
Want one vendor for HR and finance? Airbase via Paylocity for Finance is the only path of the two that offers it.

Decision tree#

Spend happens mostly on cards and travel? Brex — start free on Essentials, upgrade when policies need teeth.
Spend happens mostly on supplier invoices with approval chains? Airbase.
Need the number today without a sales call? Brex — Airbase is quote-only.
Multi-entity with international entities on both sides? Brex Premium/Enterprise for cards; Airbase if the AP ledger is the complexity.

Verdict#

Choose by the shape of your spend, not the feature grid. Brex wins the card-first company: published pricing you can act on today, global cards, travel, and controls that scale from free Essentials to custom Enterprise — and it has become a credible minimal AP tool on the way. Airbase wins the invoice-first company: procure-to-pay discipline, PO matching, and pre-spend approvals that card platforms bolt on rather than build — now under Paylocity's ownership, which changes the buying conversation to a bundle. If your finance team's week is reimbursement queues, take Brex; if it's invoice approval queues, take the quote call with Airbase.
