Brex
Global corporate cards, travel and spend management with an AI assistant that reviews expenses so people do not have to.
What is Brex?
Brex combines corporate cards, expense management, travel booking, reimbursements and bill pay into a single platform. Employees receive physical or virtual corporate cards, book travel through an integrated booking tool and submit out-of-pocket expenses for reimbursement - all within one system. An AI assistant reviews submitted expenses against company policy, flagging violations and auto-approving compliant spend so that finance teams and managers are not buried in receipt reviews.
The platform issues cards in multiple countries with local currency, which makes it particularly suited to companies with distributed or international teams. Travel booking is built in rather than bolted on - employees search flights, hotels and rental cars directly in Brex, and the spend flows through the same approval and coding workflows as card transactions.
Brex integrates with major ERPs and accounting systems including NetSuite, QuickBooks and Sage Intacct. Transactions sync with GL codes, departments and cost centers so the month-end close process has fewer manual entries to reconcile.
Where it shines
The AI-powered expense review is Brex’s most distinctive feature. Rather than routing every expense through a human approver, the system evaluates each transaction against the company’s configured spend policy - checking category limits, receipt requirements, merchant restrictions and per-diem thresholds. Compliant expenses are approved automatically, while exceptions surface for human review. This dramatically reduces the administrative burden on managers who would otherwise spend hours each week clicking approve on routine purchases.
Global card issuance sets Brex apart from many competitors. Companies can issue cards to employees in dozens of countries, often in local currency, avoiding foreign transaction fees and delayed availability. For businesses with teams across Europe, Asia or Latin America, this is a meaningful operational advantage.
The integrated travel experience is well executed. Instead of managing a separate travel tool and reconciling expenses back into the card platform, everything lives in one place. Travel policies are enforced at the point of booking rather than flagged after the fact.
Where it falls short
Startups and very early-stage companies with limited cash reserves may find it difficult to qualify for Brex cards. The underwriting process evaluates the company’s cash position, and businesses with thin balances may receive lower limits or be declined entirely. This is a practical barrier for the pre-revenue companies that originally made up Brex’s core market.
Setup and onboarding take longer than simpler expense management apps. Configuring spend policies, approval chains, ERP integrations and travel rules across a multi-country organization is inherently complex. Companies looking for a quick card-and-receipt solution may find the initial investment in configuration heavier than expected.
For companies operating entirely within the US and without significant travel spend, Ramp offers a more streamlined experience with strong savings insights and a faster onboarding process. And for organizations where travel is the primary use case and card management is secondary, Navan provides deeper travel inventory and negotiated rate access.
Conclusion
Brex is the strongest option for companies that need corporate cards, expense management and travel booking to work seamlessly across multiple countries. The AI expense review genuinely reduces administrative overhead, and the global card capabilities solve a real pain point for distributed teams. Companies without international needs or heavy travel may find simpler alternatives sufficient, but for globally operating businesses, Brex delivers a well-integrated platform that consolidates spend management into one place.
