Brex's competitors split into three groups that are easy to confuse on a feature grid. Corporate card platforms that give the software away and earn on interchange (Ramp, BILL Spend and Expense, Navan). Business banking platforms that added cards and spend tools on top of a deposit account (Mercury). And expense or HR software that sells spend management as a module and never issues you a card at all (Expensify, SAP Concur, Zoho Expense, Rippling). Brex sits in the first group and increasingly overlaps the second, which is why "Brex vs Mercury" and "Brex vs Ramp" are now the two comparisons buyers actually run.
Every price below was read on the vendor's own published pricing page. Brex, Ramp, Mercury, BILL and Tipalti were read on August 26, 2026. Where a date differs it is stated in the row. Where a vendor publishes nothing, this article says so rather than repeating a third-party estimate, because the analyst-site figures circulating for this category are frequently wrong and none of them are contractual.
Brex competitors compared on published pricing
| Competitor | Published entry price | How it charges | What it competes with Brex on | Best suited to |
|---|---|---|---|---|
| Ramp | Free $0/user/mo, Plus $15/user/mo "+ Platform fee based on team size" | Per user, plus interchange, plus an unquantified platform fee | Corporate cards, spend controls and AP, near identical positioning | Teams that want the closest like-for-like swap |
| Mercury | Mercury $0/mo, Mercury Plus $35/mo, Mercury Pro $350/mo | Per account, not per user | The business bank account underneath the card, plus invoicing and bill pay | Startups that want banking and cards from one vendor |
| BILL Spend and Expense (formerly Divvy) | $0 | Free software funded by interchange on its card | Cards, budgets and expense capture | Companies willing to adopt the card to avoid a software fee |
| BILL | Per user tiers read August 23, 2026, plus a published payment fee schedule including ACH $0.59, mailed check $1.99 and Pay Faster ACH $11.99 | Per user, plus per payment | Accounts payable and bill pay, not cards | Teams whose pain is supplier invoices |
| Navan | Business free for companies up to 300 employees; Navan Expense free for the first 5 monthly expensing users, then $15/user/mo (read August 22, 2026) | Per expensing user, plus travel booking economics | Corporate travel booking bundled with expense and cards | Companies whose largest controllable spend is travel |
| Rippling | No dollar figure anywhere on its pricing page. Its own blog publishes Expense Management at $14 PEPM and Corporate Cards at $8 PEPM (read August 19, 2026) | Per employee per month, plus a required platform fee | Bundling cards and expense into payroll and HR | Companies consolidating HR, payroll and spend in one vendor |
| Expensify | Collect a flat $5 per member/mo with no annual commitment and no card requirement; Control $18 per member/mo annual and $36 above your subscription size, cut up to 50% by Expensify Card usage to $9 and $18 (re-read at source August 31, 2026) | Per member, with a subscription-size commitment | Receipt capture and expense reports, not a card program | Teams that need expense reports and already have cards |
| SAP Concur | Roughly $7 per expense report, Plus roughly $11 (read August 5, 2026; the tilde is Concur's own) | Per report, unlimited users | Travel and expense at enterprise scale | Large companies with heavy travel and light expensing per head |
| Zoho Expense | Free up to 3 users, Standard $4/user/mo, Premium $6/user/mo (read August 5, 2026) | Per user, monthly or annual | Price, by a wide margin | Cost-sensitive teams already inside the Zoho suite |
| American Express Business | Card annual fees, no software subscription | Annual card fee, plus interchange | The underlying card and its rewards, not the software | Businesses that want a card brand and credit line, not a spend platform |
| Airbase, Coupa, Stampli, AvidXchange | No published price | Quote only | Procurement depth and enterprise AP | Buyers running a formal RFP with a procurement team |
| Expenditure | Planned at $12, $24 and $39 per user/mo, not yet on sale | Per user, no card program and no payment rail | Reading, coding and reconciling spend on the cards you already have | Teams that will not switch cards or banks |
Two things in that table cause most of the confusion. The $0 rows are not free in any meaningful sense: they are paid for by interchange on a card you have to adopt, so the real price is the card program you gave up plus the cost of moving your spend onto a new rail. And four of these vendors publish no price at all, so any comparison that puts a confident per-seat number next to Coupa or Airbase is quoting somebody's guess.
One note on Expensify, because its numbers are the most widely misreported in this table. The $5 and $9 everyone quotes are the fully discounted rates, available when you put spend on the Expensify Card. Re-read at source on August 31, 2026, Collect is a flat $5 per member per month with no annual commitment and no card requirement, so it carries no discount behind it. Control lists at $18 per member per month on an annual subscription and $36 for active members above your subscription size, and the widely quoted $9 is that $18 after the maximum 50% Expensify Card discount. Our full Expensify competitors roundup works through the billing definitions.
Who are Brex's biggest competitors?
Ramp is the closest by a wide margin. Both are venture-backed corporate card platforms that give away spend software and earn on interchange, both sell to US startups and scaleups, and both have expanded into bill pay, travel and accounting automation. If you are seriously evaluating Brex, Ramp is the other tab you have open. Mercury is second and gaining, because it attacks from underneath: it is the bank account, and cards plus expense management arrive as features of the account rather than as a product you buy.
Below those two the field sorts by which problem you are actually solving. Employee expense reports without a card program: Expensify or Zoho Expense, both far cheaper than most buyers expect. Corporate travel: Navan. Enterprise travel and expense with global policy and tax handling: SAP Concur. Supplier invoices and paying them: BILL. Consolidating spend into payroll and HR: Rippling. And if the card itself is what you want, with a credit line and a rewards program rather than a software platform, that is American Express or your existing bank.
Brex vs Mercury
This is the comparison that has changed most in the last two years, and the two products are not the same category. Mercury is a business banking platform: you open an account, hold your operating cash there, and get cards, bill pay, invoicing and expense management as part of it. Brex is a spend platform that also offers a business account. The practical question is which one you want to be your primary money home.
On price, Mercury publishes Mercury at $0 a month, Mercury Plus at $35 a month and Mercury Pro at $350 a month, with 15 percent off on annual billing. Critically, those are per account, not per user, so a 40-person company on Mercury Plus pays $35 a month total. Brex publishes $0 per user per month and $12 per user per month for Premium, so the same 40-person company on Premium pays $480 a month. That is a large enough gap to decide the question on its own if your requirement is cards plus basic expense controls.
What the extra money buys on Brex is depth in spend management: policy enforcement, approvals, receipt capture, budgets and accounting sync built for a finance team rather than a founder. Mercury Plus is aimed at invoicing and payment workflow, with ACH debit invoicing at $1 per transaction, an invoicing API capped at 500 invoices created per month and unlimited 1099s. Mercury Pro adds a dedicated relationship manager, ACH debit invoicing at $0 per transaction, an uncapped invoicing API and NetSuite categorizations.
Two facts worth carrying into the decision. Mercury states plainly on its own site that it "is a fintech company, not an FDIC-insured bank", with banking services provided by partner banks, and its Treasury product unlocks at a $250,000 balance. Brex LLC is a wholly owned subsidiary of Capital One, N.A. following an acquisition that completed on April 7, 2026 at $5.15 billion, which puts a national bank behind the platform and is the single biggest change to Brex's competitive position in years. We covered what that means in detail in our write-up of the Capital One acquisition of Brex.
Brex vs Ramp
These two are close enough that the decision usually turns on two details rather than on features. The first is pricing transparency. Brex publishes a complete list: Essentials at $0 per user per month and Premium at $12 per user per month, with Enterprise and Smart Card quoted custom. Ramp publishes Free at $0 per user per month and Plus at $15 per user per month "plus Platform fee based on team size", and it has never said what that platform fee is. When you are modeling a three-year cost at growing headcount, one of those numbers is budgetable and the other is not.
The second is payment fees. Brex states that it charges no transaction fee on domestic wires, international wires, ACH or checks sent from a Brex business account, though it applies an FX markup of up to 3 percent. Ramp began metering bill pay on June 1, 2026, with standard ACH at $0.59, standard check at $1.99, same-day ACH at $10, domestic wire at $15, international SWIFT in USD at $20 and overnight check at $20. Paying from a Ramp Checking Account waives most of those but not the overnight check. If you send a lot of wires, that difference outweighs the $3 per user gap in the subscription. Our side-by-side breakdown lives on the Ramp vs Brex comparison, and the full price lists are on Brex pricing and Ramp pricing.
Brex vs Amex
People searching this are usually asking whether they need a spend platform at all. American Express sells a card: a credit line, a rewards program, an annual fee and a statement. Brex sells software wrapped around a card: budgets, policy rules, receipt capture, approvals and an accounting sync, with the software funded by interchange rather than billed separately at the entry tier.
The honest answer is that plenty of profitable US businesses run for years on an Amex program plus a bookkeeper, and the reason to add a platform is not the card. It is that nobody can tell you what was spent until the statement arrives, receipts go missing, and coding happens once a month in a rush. If that is the problem, note that you do not have to change cards to fix it. Software that reads receipts and reconciles them against the transactions on your existing Amex or bank program solves the same pain without a migration, which is the segment Expenditure is built for.
Brex alternatives for small business
Brex has moved steadily upmarket, and small teams often find the fit awkward. Three routes work better at that size. If you want banking and cards in one place and have a handful of people, Mercury at $0 or $35 a month per account is dramatically cheaper than per-user pricing. If you already have cards you are happy with and just need expense reports, Zoho Expense at $4 per user per month or Expensify's Collect tier are the value picks. And if your actual bottleneck is supplier invoices rather than card spend, none of these are the answer; that is an AP problem, and we compared that field in our guide to BILL competitors and Bill.com alternatives.
A fourth route deserves a mention because it costs nothing to test: keep the cards, fix the paperwork. Most small businesses that think they need a card platform are really losing hours to receipts arriving by email, photographed at dinner, or never submitted at all. Pulling structured data out of those emailed documents is a solved problem on its own, and if receipts and statements land in a shared inbox you can extract the data straight out of those emails into a spreadsheet before deciding whether a whole new card program is justified.
Is Brex legit?
Yes. Brex Inc. was founded in 2017, is used by tens of thousands of US companies, and its card-issuing entity Brex LLC is a licensed money transmitter (NMLS #2035354). Since April 7, 2026 Brex LLC has been a wholly owned subsidiary of Capital One, N.A. The question behind the question is usually whether a venture-backed fintech will still be there in five years, and the acquisition materially changes that answer: the platform now sits inside a national bank rather than depending on its own funding runway.
Brex card competitors and the interchange question
Every free tier in this category is funded the same way. When your team spends on the platform's card, the platform earns interchange from the merchant, typically somewhere around 2 percent of the transaction, and it hands you the software out of that revenue. This is a legitimate model and it is not a trick. But it does mean three things buyers routinely miss.
First, the free software is conditional on moving your spend. If you keep half your volume on an existing Amex or bank card, the economics that justify the free tier do not fully apply to you, and the vendor's enthusiasm for your account will reflect that. Second, you are giving up whatever your current card program returns, whether that is points, a rebate or a credit line you have spent years building. Compare the platform's rewards against what you already earn, not against zero. Third, interchange-funded platforms have a structural interest in you paying by card rather than by ACH, which is the cheapest rail for you and the least profitable for them.
This is the reason a per-user subscription with no card program attached is not automatically the more expensive option. It is a different trade: you pay in cash for software and keep every dollar of card economics, instead of paying in interchange and keeping the cash.
What to check before you switch
Three things decide whether a migration is worth it, and none of them are on a feature grid.
Where does your spend actually go? Pull twelve months of transactions and split them into card spend and supplier invoices paid by ACH or check. If the invoice half is larger, which it is at most US companies past twenty people, a card platform is optimizing the smaller number. That points at an AP tool or a reconciliation layer instead.
What breaks at close? If the answer is missing receipts and wrong GL coding, changing card providers does not fix it. Every platform in the table captures receipts; the differences are in how well they read line items, how they handle a tip added after the authorization, and whether coding is proposed or keyed. Our account reconciliation software guide breaks down which of the six reconciliations your close is actually stalling on, because that diagnosis changes the shortlist more than any pricing table.
What does the accounting sync really write? Ask specifically whether the integration writes the transaction, the GL coding, the class or location and the attached source document into QuickBooks, Xero or NetSuite, and whether it reads your chart of accounts so coding options match your books. A one-way CSV export is not an integration, and this is where migrations most often disappoint after the contract is signed.
How Expenditure fits
Expenditure is not a Brex competitor in the card sense, and pretending otherwise would waste your time. It issues no cards, holds no deposits and moves no money. It sits on top of whatever cards and bank accounts you already run, reads every receipt and supplier invoice with line-level extraction, proposes a GL account per line based on the vendor and how you coded that vendor before, matches each document to the transaction it belongs to, chases whatever is unmatched with the person who spent the money, and posts the result to QuickBooks, Xero or NetSuite with the original document attached.
That is the right layer if your problem is visibility and paperwork rather than the card itself, and it is the wrong layer if you genuinely want a new card program with a credit line. Expenditure is planned at $12, $24 and $39 per user per month and is not yet on sale. If you want the wider field rather than just the Brex side of it, we also compared Ramp competitors on published pricing and maintain a running Brex alternative comparison.
