Brex Has Become the Default Spend Platform for High-Growth Companies
Brex launched in 2017 targeting a gap in the market: startups that couldn't qualify for traditional corporate cards. Its cash management account, high-limit corporate cards, and modern expense management platform quickly attracted thousands of venture-backed companies.
By 2024, Brex serves tens of thousands of businesses ranging from seed-stage startups to large enterprises, processing billions in corporate spend. The platform offers real-time spend visibility, budget controls, receipt matching, and accounting integrations with NetSuite, QuickBooks, and Sage.
But the platform's power is conditional. Brex's value depends on cardholders submitting receipts promptly, expenses being coded correctly, and budget owners reviewing reports regularly. In practice, these tasks fall through the cracks — especially in fast-moving startups where everyone is focused on the product or the customer rather than expense administration.
This is the problem virtual assistants are uniquely positioned to solve.
What a Brex VA Handles
A virtual assistant supporting Brex operations takes ownership of the administrative tasks that keep spend data clean and useful. Core responsibilities include:
- Receipt collection and matching: Following up with cardholders who have outstanding receipt submissions, uploading receipts to Brex, and ensuring every transaction has documentation before the monthly close.
- Expense coding and categorization: Reviewing transactions and applying the correct GL codes, cost centers, or project tags based on the company's chart of accounts and Brex budget structure.
- Budget monitoring and alerts: Reviewing budget utilization across departments or cost centers, flagging categories approaching their limits, and preparing weekly or monthly budget summary reports for finance or the CFO.
- Vendor and subscription audits: Periodically reviewing recurring charges on Brex cards, identifying subscriptions that are no longer in use, and flagging potential duplicates for cancellation.
- Month-end close support: Ensuring all Brex transactions are coded and receipted before the accounting team exports to the ERP or accounting system, reducing the back-and-forth that delays closing.
The Receipt Problem Is Real and Costly
Brex's own data has shown that incomplete receipt submission is one of the top pain points for finance teams using the platform. When receipts are missing, transactions cannot be coded accurately. When coding is wrong, financial statements are unreliable. When statements are unreliable, decisions are made on bad data.
For companies raising follow-on funding or preparing for an audit, messy expense records are a material problem. Investors and auditors expect clean books, and cleaning up historical expense data retroactively is far more time-consuming than maintaining it in real time.
A Brex VA who owns receipt collection and coding ensures the data stays clean as transactions occur — making month-end close faster and due diligence ready at any time.
Brex's Permission Controls for VAs
Brex allows admins to create team members with defined roles including Bookkeeper, which provides read access to all transactions and the ability to add memos and upload documents without spending access or the ability to issue cards.
This role is purpose-built for a VA or bookkeeper supporting expense management. It provides exactly the access needed to do the job without exposing the account to risk.
Startups and growth-stage companies looking for reliable, finance-literate virtual assistants can explore options through Stealth Agents, which provides dedicated VAs experienced in fintech platforms, accounting workflows, and back-office operations.
The ROI Case for Expense Management Support
For companies with 10 or more Brex cardholders, the monthly administrative work around receipts and coding can consume 15 to 30 hours of staff time if it is being managed reactively rather than proactively. A part-time VA handling this function typically costs less than two hours of an in-house accountant's billable time.
The ROI compounds further when cleaner expense data leads to faster monthly closes, better budget visibility, and fewer surprises for the finance team.
The Operational Reality of Fast Growth
Brex is designed for companies moving fast. But moving fast without operational discipline in spend management creates compounding administrative debt. Virtual assistants provide the consistent, detail-oriented support that prevents that debt from accumulating.
