Brex vs QuickBooks Online

Brex a spend management platform for venture-backed startups and large teams. They also have a lightweight banking product called Brex Cash that functions as a simple business checking account.

We evaluated Brex years ago while comparing corporate card platforms. At the time it looked promising, and a lot of startups were using it for business banking. But the reality is Brex isn’t really designed to be your primary business bank, it's much more of an expense management platform built for startups that have raised serious venture capital.

The product has taken a strange turn over the past few years. After onboarding a large number of small and mid-sized businesses, Brex abruptly shut down access for many of those smaller accounts (including ours! I guess we weren't "startup" enough) and repositioned the platform almost entirely toward venture-backed startups or companies doing roughly $400K+ in monthly revenue.

For that reason, Brex isn't going to be something we recommend. But even if that weren't the case, when you compare the actual day-to-day experience, especially things like UI/UX and automated expense reconciliation, newer platforms like Ramp and BILL Spend & Expense have pulled ahead for most modern SMBs.

• Designed specifically for venture-backed startups
• Virtual cards and spend controls are easy to set up
• Startup perks and partnerships (especially through YC)

• Not available to most small businesses anymore
• Accounts have historically been closed or restricted unexpectedly
• UI/UX and accounting automation lag behind competitors
• Banking features are limited compared to dedicated business banks

Brex provides corporate cards designed for startups and larger teams. Their core offering is pretty much the same as competitors': issue virtual cards, set spending limits, and control how funds are used across different departments.

Transactions from Brex cards feed into expense reports, where AI categorizes purchases, matches receipts, and enforces company policies. Employees can capture receipts through the mobile app, while finance teams get instant visibility into budgets and spending across teams or projects.

Brex Cash is their lightweight banking product that acts like a checking account where teams can store funds and manage company spending. It works well enough for simple use cases, but it’s fairly barebones compared to dedicated business banking platforms like Mercury, which offer much deeper banking features and integrations.

Essentials: Free. Best for startups and small teams that want Brex corporate cards, basic expense controls, accounting integrations, and bill pay.

Premium: $12 per user/month. Best for mid-sized companies that need more advanced expense policies, approval workflows, multi-entity support, and deeper ERP or HRIS integrations.

Enterprise: Custom pricing. Designed for large global organizations that need unlimited entities, advanced implementation support, and a dedicated account manager.

Note: Brex is primarily available to venture-backed startups or companies generating roughly $400K+ in monthly revenue. Many smaller businesses will not qualify for approval.

While QuickBooks Online includes some basic expense tracking features, it is not a full expense management solution. For example, QBO does not provide robust support for virtual cards or company-wide spending controls.

Some people have mentioned that QuickBooks Online allows for some expense management features like virtual credit cards, that said, a tool like Bill Spend & Expense (formerly Divvy) does so much more for expense management than simply allowing for a one-off virtual card though. Unlike QBO, a proper expense management tool allows you to go deeper, as it ties in individual and team budgets (across the entire company), all to ensure your company only allocates what they have budgeted for.

QBO also does not have proper receipt matching that automatically ties the receipt from your email to the individual transaction.

QBO does not have credit card rewards with their virtual credit card solution either.
