Brex vs. BILL: Side-by-side comparison

Both Brex and BILL (formerly Divvy) offer corporate cards, expense tracking, and accounting integrations as part of their expense management platform. But how they work, who they're built for, and their qualification requirements can look very different.

Brex previously catered to startups and growth-stage companies that valued agility and automation. But their recent acquisition by Capital One may have some customers wondering whether the fintech platform might shift its focus.

BILL, on the other hand, prioritizes budgeting discipline, making it a solid fit for teams that want to manage costs tightly.

How Brex and BILL stack up at a glance

Brex fits fast-growing and venture-backed teams with higher card spend and global needs. BILL suits traditional small and midsize businesses that want free budgeting tools and strong accounts payable.

Brex and BILL both make business spending easier, but they come from different roots in the fintech landscape.

Brex launched in 2017 and pivoted from a VR startup to serving one core market: young companies that struggled to get credit cards. They built a fintech platform offering charge cards, expense management, and finance automation features.

In January 2026, Capital One announced it would acquire Brex for $5.15 billion, and the deal officially closed on April 7, 2026. The acquisition introduces uncertainty for current and prospective customers around product direction, pricing stability, and strategic priorities. Given Capital One's traditional focus on enterprise clients, the deal may signal a shift away from the startups and high-growth companies Brex was originally built to serve. If you're curious how Capital One business credit card requirements compare to Brex's current underwriting, it's worth reviewing both before you apply.

BILL, originally an independent startup, focused on combining corporate cards with an expense management software that emphasizes proactive budgeting and control over spend. After BILL acquired Divvy in 2021 for $2.5 billion, it expanded as "BILL Spend & Expense," adding tight spend policies and credit lines.

Which businesses qualify for Brex and BILL?

Both Brex and BILL serve U.S. Businesses, but they evaluate applicants in different ways. This impacts who gets approved, and it remains to be seen whether Brex's acquisition by Capital One might change its qualification requirements.

Brex approval requirements

Brex takes a non-traditional approach to underwriting. It doesn't require a personal guarantee or credit check. Instead, it reviews your company's cash balance, revenue trends, and business model.

To qualify, most startups need at least $50,000 in the bank. Brex may be a good option if you have raised funding, operate as a corporation or LLC, and want to avoid putting your personal credit on the line.

Brex actually runs two separate eligibility paths, according to its account requirements page: commercial applicants that haven't raised venture capital need more than $500,000 in annual revenue, while venture-backed startups need to have raised funding and hold roughly $50,000 in minimum cash instead, without the revenue threshold. The two paths don't stack, so check which one describes your business before you apply.

But it's not open to everyone. Sole proprietors and unregistered freelancers are excluded, and Brex restricts access to industries like crypto, cannabis, and adult entertainment. The application process is fast: you can usually get approved within a day if you meet the criteria.

But following Capital One's acquisition of Brex, it's unclear whether these underwriting criteria will remain unchanged. Banks typically have different credit risk models and approval processes than independent fintechs. If you're evaluating Brex, it's worth confirming current underwriting requirements directly with the company, as policies may evolve as the acquisition closes.

BILL approval requirements

BILL follows a more traditional credit model for its business credit cards and expense reporting. It runs a soft pull on your personal and business credit but doesn't require a personal founder guarantee.

Cash requirements are usually lower: most reviews put the bar around $20,000 in your business account. That makes it more accessible for bootstrapped or early-stage companies that haven't raised outside funding.

The initial application won't affect your personal credit score and doesn't require a personal guarantee, per BILL's own card requirements FAQ. Underwriting still looks at the cash flow in your connected business bank account, alongside that soft credit pull.

So, if your business has strong cash reserves but a limited credit history, Brex is likely the better fit. On the other hand, you should choose BILL if your business has solid credit but lower cash on hand. Either way, what you pay after approval matters just as much.

Brex vs. BILL pricing and fees

Both platforms are largely free as core software, so the real cost difference shows up in premium tiers and payment fees.

Brex pricing starts with a free Essentials plan. Its Premium plan costs $12 per user per month and unlocks live budgets and multi-entity support.

On the bill.com pricing side, BILL Spend & Expense is $0 per user per month for cards, budgets, and expense tracking. BILL's accounts payable plans run $49 per user per month for Essentials, $65 for Team, and $89 for Corporate, with a $0.59 fee per ACH payment.

Ramp's spend management software is free to use.

Pricing on all three platforms changes quickly, so confirm current rates directly with each vendor before you sign anything.

Corporate card features

Brex offers stronger card features if you want flexibility, speed, and higher spending power. It supports unlimited virtual cards, dynamic spending limits, and layered spend controls that scale with your business.

BILL is the better pick if you need strict budget enforcement and preset limits on every card. It's built to prevent overspending and works best for teams that prioritize control over flexibility.

Virtual cards

Brex provides you with unlimited virtual cards at no additional cost. You can issue one for each vendor, subscription, or team member and set rules like auto-expiration or merchant locks through the management software. For companies managing dozens of software tools or contractors, this setup reduces risk and makes reconciliation easier.

BILL also offers virtual cards, but with a stronger focus on control. Each card is tied to a pre-approved budget within the expense management platform. You can't overspend, which helps keep distributed teams in check. However, you may encounter volume or administrative friction if you frequently need to issue cards or frequently change budgets.

If you prioritize speed and flexibility, Brex wins. If you need upfront budget enforcement, BILL holds the edge.

Spend controls

Both platforms let you restrict spending by category, amount, or vendor, but they handle it differently.

Brex allows you to build layered policies. You can set department-wide rules, limit international usage, or flag transactions that break company policy. It's designed for teams that need flexibility and oversight at the same time.

BILL's controls are more rigid by design. You create a budget first, and every card is locked to it. That means no one can spend beyond what's approved. While this keeps spending predictable, it can slow teams down if budget changes require admin approval.

Use Brex if you want flexible controls that adapt to your team's unique operating style. Choose BILL if you need hard-stop limits on every card.

Credit limits

Brex offers dynamic credit based on real-time cash and revenue. If your business holds strong balances or growing income, you are likely to get a higher limit. Some reviews estimate credit limits 10 to 20 times higher than traditional cards, though that's a third-party estimate rather than a limit Brex guarantees.

BILL works like a traditional credit line. Limits start as low as $1,000 and increase with a history of usage and credit strength. For companies just getting started or managing tighter cash flow management, this can offer a safe entry point, but it might not scale quickly.

Brex is the better option if you're growing fast and want access to higher limits without reapplying. BILL is better if you prefer a fixed, credit-based approach and tighter control over your expenses.

Accounting and software integrations

Brex offers stronger accounting integrations overall, particularly if you rely on automation to expedite close cycles and minimize manual work. It supports real-time syncing with accounting software like NetSuite, QuickBooks, Sage Intacct, and Xero. Transactions are auto-coded using AI and custom spend rules, mapped to the correct GL accounts, and synced instantly.

BILL also integrates with major accounting platforms but works more like a traditional expense tool. Transactions sync only after receipts are uploaded and approvals are completed. It's reliable and easy to set up but requires more manual input to keep everything updated. Finance teams evaluating AI accounting software will find that Brex's real-time sync and auto-coding capabilities align more closely with modern automation standards.

Here's how Brex and BILL compare on accounting and integration features:

Budgeting and expense management

If you're looking for strong budgeting tools and clean expense workflows, both Brex and BILL deliver, just in very different ways. Your decision depends on whether you want automation with flexibility or pre-set control and structure.

Budget creation and enforcement

BILL uses a budget-first system that forces teams to plan their spending before it occurs. You assign budgets to departments, users, or projects, and every card is tied directly to those limits. If a budget runs out, the card gets declined.

This structure gives finance teams full control and ensures no one spends outside of their assigned amount. It's ideal for businesses with fixed spending plans, approval layers, or distributed teams.

Brex, by contrast, uses policy-based controls rather than locked budgets. You can set rules around categories, vendors, or transaction limits, but the system allows flexibility.

Managers can override limits or approve exceptions if needed. For fast-moving teams or startups where spending shifts frequently, this model avoids bottlenecks while still maintaining oversight.

Real-time expense tracking

Both platforms offer real-time tracking, but they present the information in different ways.

BILL shows spending updates within each assigned budget. You will see a running tally of how much each team or project has used, how much is left, and who's spending it. Alerts notify managers as budgets are depleted, giving you constant oversight.

Brex also updates in real-time but focuses more on centralized visibility. You receive a dashboard that categorizes spending by team, vendor, or policy group. Rather than checking each budget, you can see broader trends across the company and drill down as needed.

Approvals and policy enforcement

BILL bakes approvals into its budgeting flow. You create a budget and assign it to a team; any new spending outside that budget requires approval before the card is used. This model is well-suited for companies that require layered authorization and minimize policy violations.

Brex is built for speed. While it allows custom policies, flagged transactions, and post-spend reviews, it doesn't enforce pre-approval unless configured manually. This approach suits businesses that trust their team leads to manage spending and want to minimize administrative friction.

Receipt capture and categorization

BILL requires users to upload receipts via mobile or desktop. You can't close the books until receipts are submitted. This ensures compliance but puts the burden on users. Admins can easily track which receipts are missing and send follow-ups.

Brex automates most of this process. It uses email matching, merchant data, and machine learning to attach receipts automatically. Missing items get flagged for follow-up, but most are handled in the background.

Accounts payable and bill pay

This is where the two platforms diverge most: BILL is built around accounts payable and vendor invoices, while Brex treats bill pay as one part of its broader spend platform.

BILL's strength is the full payables cycle, from invoice capture and approval routing to payment execution. It also handles international payments to 130+ countries and 100+ local currencies, which matters if you pay overseas vendors regularly.

Brex takes the bundled route with AI-assisted bill pay inside its spend platform. You get fewer standalone payables features than a dedicated AP product, as BILL's own comparison page highlights.

Ramp Bill Pay processes invoices 2.4x faster and with 86% fewer clicks than legacy AP software. Its AP Agents auto-code invoices, catch duplicates, and screen for fraud across 60+ signals, so accounts payable automation covers the judgment work too. See Ramp Bill Pay for the full workflow.

Cashback and rewards

Brex and BILL both offer points-based rewards. But how you earn, redeem, and maximize value differs.

Brex offers a better rewards experience for modern teams. Its points are easier to earn and redeem, though its rewards structure might change after being acquired by Capital One. BILL can offer higher rates in specific categories, but only if you commit to weekly repayments and stay within spending caps.

Earning rewards

Brex gives you fixed multipliers across common business categories. You earn 7x on rideshare, 4x on travel bookings, 3x on restaurants, 2x on software, and 1x on everything else, without worrying about payment schedules or usage caps. This model works well if you have ongoing spending across multiple teams or tools.

However, Brex's acquisition by Capital One may leave some customers wondering about changes to their rewards structures. Brex continues to operate as-is for now, but like all card issuers, its rewards may change in the future.

BILL offers higher rewards in specific categories, such as 7x on restaurants and 5x on hotels, but only if you pay your balance on a weekly basis. If you choose monthly payments, those multipliers drop significantly. BILL also caps rewards on many categories at $5,000 per month.

Redemption

Brex hasn't changed its redemption options since being acquired by Capital One, but it's a possibility to keep an eye on. As of now, you can use points for travel, statement credit, or transfer them to seven airline partners. There's no waiting period, no minimum balance, and your points don't expire.

BILL's redemption is more restrictive. You can use points for travel, gift cards, or cash, but only after earning 5,000+ points. Points expire after 12 months, and you must spend at least 30% of your credit line each month to retain them within the management solution.

Automation and AI tools

Brex leads in automation and AI features with powerful tools that let your team operate hands-free. With that said, since Capital One announced its deal to acquire Brex, there may be some concern that Brex's nimble fintech experience could gradually take on the feel of a traditional bank, with slower innovation and less responsive support.

BILL offers useful automation, but it's more workflow-driven than autonomous AI. When a user makes a purchase, BILL instantly logs it against a budget, sends reminders to upload receipts, and organizes spending reports. However, it does not use AI to make decisions or manage exceptions.

Every action, such as reclassifying an expense or updating a policy, requires manual steps. Teams that rely on BILL still report saving a few hours each month, but much of that comes from better structure, not intelligent automation.

The biggest difference comes down to how much you want the system to think for you. Brex reduces human involvement across categorization, approvals, and compliance. BILL automates the flow but leaves decisions and clean up to your team.

Ramp takes this a step further with AI-driven categorization and receipt capture via SMS, email, or vendor integrations like Amazon and Uber. Ramp's Policy Agent is an always-on AI reviewer trained on your actual policy, catching 7x more out-of-policy spend than rule-based systems at 99%+ accuracy—and it handles auto-coding in the background so your team rarely has to intervene. So Brex automates, BILL relies on workflows, and Ramp reviews your spend agentically.

Security and compliance

Security is about controlling access, protecting sensitive data, and ensuring your team stays compliant without slowing down financial operations. For finance teams, the essentials usually include data encryption, access controls, audit logs, fraud detection, and regulatory certifications.

If you need deeper controls, stronger automation, or coverage across multiple compliance frameworks, Brex goes further. Its security and compliance safeguards are almost certain to improve even more once it becomes part of Capital One.

BILL handles security well for most SMBs. However, it doesn't offer the same level of configurability or certifications. If safeguarding finances and meeting compliance standards is key, here's how the two solutions compare:

Customer support and onboarding

Both Brex and BILL offer dedicated onboarding, but their approaches and paces differ.

Brex is better suited for companies that want a fast, guided setup for their business credit cards. Most users report onboarding in under a week, per customer reviews. You get a dedicated onboarding specialist, real-time chat, and support from product experts who've helped scale fast-growing startups.

Users benefit from the clarity and speed of Brex's process. For small teams or companies moving quickly, the experience feels lightweight and immediate. However, with Capital One's acquisition, it's uncertain whether Brex will maintain this rapid onboarding model. Traditional banks aren't typically known for same-day activation or fintech-style support speed.

BILL, on the other hand, takes a more structured approach. You are assigned a launch manager who helps map budgets, integrate accounting systems, and train your team. Onboarding typically takes 4 to 6 weeks per customer reviews, depending on complexity.

The process is detailed and thorough, which works well for larger teams that need to roll out custom budgets and user roles across departments. Once live, BILL's support scores high on reliability. However, urgent help may take longer compared to Brex's real-time options, though as Brex transitions under Capital One ownership, that speed advantage may narrow.

How Ramp compares to Brex and BILL

If you're looking for a corporate card that goes beyond spend management, Ramp delivers the most complete package. While Brex and BILL each offer strong features, Ramp brings real automation, global flexibility, and deeper finance controls under one roof. Here's how all three compare across the areas that matter most for modern businesses:

There's no one-size-fits-all answer here. Brex suits fast-scaling teams that want automation and flexible limits, while BILL suits teams that need strict, budget-first guardrails. Ramp combines that automation and control in one independent platform.

Why growing companies are choosing Ramp

Ramp is the better Brex and BILL alternative because it's built for finance teams that want to move fast without losing control. As an independent spend management platform, Ramp's product roadmap is driven entirely by customer needs, not the competing priorities of a legacy banking institution.

Unlike Brex, which is now being acquired by Capital One, Ramp gives you deeper automation, fewer manual tasks, and real-time visibility across all spending without the uncertainty that comes with bank ownership.

You don't need perfect credit or a massive bank balance to get started. Ramp approves businesses with just $25,000 in the bank and doesn't require a personal guarantee. That makes it easier for early-stage startups to qualify without putting personal credit at risk. And because Ramp remains independent and purpose-built for high-growth companies, you won't face the risk of underwriting standards changing.

You'll also spend less time chasing receipts or cleaning up your books. Ramp's AI automatically codes over 90% of transactions and offers real-time integrations with tools like NetSuite, Xero, and QuickBooks Online. That means fewer errors and 40+ hours per month saved on month-end close.

With faster product velocity and a customer-driven roadmap, Ramp continues shipping features that modern finance teams actually need, without waiting for bank approval cycles or enterprise-first priorities to clear.

Ramp also offers cashback rewards on purchases, with controls built into the card before spend happens. See how the all-in-one card and spend management platform compares to what you're using today.
