Brex Cards for Business and Corporate Spending

This site is an independent editorial project about a narrow subject: business and corporate card products, the spend management controls attached to them, and the expense management workflows that sit downstream. We use the search terms people actually type — brex card, brexcard, brex business credit card, brex corporate card — as the entry point into structural explanations of how these card categories work.

We are not Brex, and we are not a broker, lender, issuer or affiliate. Nothing here is an application, an offer, a credit decision or financial advice. If you need product terms, pricing, eligibility rules or account support, those come from the provider directly. What we can do is explain the vocabulary and the mechanics well enough that provider documentation becomes readable.

1. The account

   One company relationship with one liability structure and one settlement arrangement. This layer decides whether the company or an individual carries the obligation, and whether balances settle in full each cycle or can be carried. Get this wrong and nothing downstream compensates for it.

2. Issuance

   Creating instruments on that account: physical cards for named people, virtual cards scoped to a vendor or project, team cards tied to a budget. Issuance is where a program either stays deliberate or drifts into a handful of shared high-limit cards.

3. Policy

   The written rules — who may spend, on what, up to how much, with what documentation. Policy that cannot be expressed as a configurable rule is policy that will be enforced inconsistently.

4. Authorisation

   The real-time decision on each transaction. This is the only layer that can actually prevent spending, which is why limits and category rules matter more than approval workflows for anything you genuinely need to stop.

5. Reconciliation

   Turning posted transactions into documented, coded accounting records and closing the period. Most of the perceived pain of a card program lives here, and most of it is caused by decisions made in the first two layers.

The layer model also explains why the search terms overlap so badly. brex corporate card and brex business credit card are mostly questions about layer one. brex card and brexcard are usually questions about layers two and three. Anyone asking how to stop a specific category of spending is asking about layer four, and anyone complaining that month-end takes a week is describing layer five.

• I do not know which card category I need The cards hub lays out the taxonomy and points each search term at the page that answers it.
• I need to explain the difference to someone else A structural side-by-side on liability, settlement, administration and control depth.
• I am new to this and want the fundamentals The corporate card guide starts from the definition and builds up to program administration.
• Our limits are either too tight or pointless How limit types interact at authorisation, and how to size a limit that stops causing exceptions.
• Month-end close is taking too long What can genuinely be automated in an expense pipeline, and what will always need judgement.
• We are an early-stage company setting this up Card structure for companies with heavy software spend and almost no finance headcount.
• I own the close and the audit trail The controller’s view: policy enforcement, evidence, exception volume and predictable close.
• I am evaluating providers A criteria-based evaluation framework — provider categories and due diligence, no scores or rankings.
