Brex

Brex is a corporate card and spend management platform combining cards, expense management, bill payment, travel booking, and real-time spend visibility, with automated receipt collection and configurable approval workflows.

How accounting firms use it

Firms recommend it to clients that need spend controls and current visibility rather than a monthly statement. Because transactions and receipts arrive continuously and post to the ledger with categorisation applied, the month-end card reconciliation that normally holds up a close largely disappears.

For firms doing outsourced controller work with venture-backed clients, there is a second consideration: investors expect timely reporting, and a client whose card spend is reconciled weeks in arrears cannot produce it. Continuous data flow makes monthly reporting deadlines achievable.

Key features

Cards are issued per employee, vendor, or project with limits and merchant category restrictions applied at authorisation, so policy is enforced when a purchase is attempted rather than reviewed afterwards. Receipt capture works by mobile app, email forwarding, or automatic matching for common vendors.

Bill payment covers approval routing and execution, and travel booking is built in with policy controls — an uncommon combination in this category.

Accounting sync supports dimension-level mapping to QuickBooks Online, NetSuite, Xero, and Sage Intacct, with rules coding transactions on the way through.

Who it’s best for

Growth-stage and mid-market businesses, particularly venture-backed technology companies where the platform has its largest base and where underwriting terms suit companies without long trading histories.

Clients with straightforward expense needs may find a conventional business card and light expense tracking sufficient. Ramp is the direct competitor and worth quoting alongside it, while Expensify remains stronger for reimbursement-heavy workflows and SAP Concur for complex corporate travel policy.
