Buyer Eval

Brex vs Ramp vs Mercury

The first finding: you may be comparing three different kinds of products.

Brex, Ramp, and Mercury increasingly overlap. All three can touch cards, expenses, payments, and finance operations. But their centers of gravity are different.

The useful question is not simply “Which is best?” It is: what finance problem are you actually trying to solve?

Updated September 2026 Evidence checked: September 28, 2026 Public sources checked Buyer Eval v4.1.1

The short answer

What we found

  1. They start from different places. Mercury starts from the bank account, Ramp from spend automation and AP, Brex from the corporate card and global spend. The overlap is real, but the product each one is built around is not the same.
  2. “Free” ends at a different point for each vendor. Mercury’s free plan reimburses out-of-pocket expenses for up to 5 active users a month. Ramp’s direct NetSuite and Sage Intacct integrations sit in Ramp Plus, whose platform fee is not published. Brex Essentials stops at two entities. A 50-person company can cross one of these lines in its first month.
  3. Ramp’s Bill Pay economics depend partly on the funding method. Ramp publishes transaction fees of $0.59 per standard ACH, $10 per same-day ACH, $15 per domestic wire, and $20 per international SWIFT payment, and says eligible transaction fees are waived when payments are made from Ramp Checking.
  4. All three underwrite cards on cash, so consolidation is built into the model. Published eligibility and limit rules all lean on the cash you hold, and Brex and Mercury tie limits to balances held with them. Choosing a card vendor can become a decision about where your cash lives.
  5. Brex is now part of Capital One. Capital One completed its acquisition of Brex on April 7, 2026. Buyers evaluating Brex should account for the change in areas such as underwriting, banking relationships, product roadmap, and vendor concentration. Buyer Eval does not assume the acquisition itself is an advantage or a disadvantage.

What the evidence shows

Finding 01

How is Mercury different from Ramp? Mercury still starts from banking

Mercury’s pricing page leads with the account: the core plan is $0 a month, with Mercury Plus at $29.90 a month and Mercury Pro at $299 a month billed annually ($35 and $350 billed monthly). Bill Pay is free to use and sends ACH, domestic and international wires, and checks. Domestic wires and ACH are free; non-USD international wires carry a 1% conversion fee.

Everything else is layered on the account. The IO card’s limit is based on the balances you hold at Mercury and on any external accounts you link, and the balance is paid in full each period. Treasury is available only above $250,000 across Mercury accounts, and it is an advisory product (Mercury Advisory LLC, custody at Apex Clearing), so it is SIPC-covered, not FDIC-insured.

This is not a weakness; it is the center of gravity. If the job is “run the company’s money well,” Mercury is shaped around it. If the job is “control and automate spend across 50 people,” check the tier lines first: the free plan reimburses up to 5 active users a month, Plus 20, Pro 250, and NetSuite categorizations are listed in Pro.

Mercury itself is a fintech, not a bank: its pricing page says banking services are provided through Choice Financial Group and Column N.A. An independent report says the OCC conditionally approved Mercury’s national bank charter, with FDIC and Federal Reserve approvals still to come.

Finding 02

Ramp starts from finance operations and spend automation

Ramp’s free tier is $0 per user per month and combines corporate cards, expense management, bill pay, accounting automation, and treasury. Ramp’s help center says its core card and expense software is free to use.

The paid line matters for this scenario. Ramp Plus costs $15 per user per month plus a “platform fee based on team size” that the pricing page does not quantify, with 20% off for annual billing. Plus is where Ramp lists procurement and purchase-order workflows, multi-entity and international capabilities, and direct NetSuite, Sage Intacct, and Dynamics 365 integrations. Procurement is also marked as an add-on to Plus or Enterprise.

The “yes, but” example: Ramp’s Bill Pay economics depend partly on the funding method. Ramp’s pricing page advertises “free, same-day ACH, domestic and international wires.” Ramp’s Bill Pay fee documentation, as of the evidence-check date, lists transaction fees of $0.59 per standard ACH (effective June 1, 2026), $10 per same-day ACH, $15 per domestic wire, and $20 per international SWIFT USD payment. It says that when paying out of the Ramp Checking Account, transaction fees for standard ACH, standard check, same-day ACH, domestic wires, and SWIFT transfers are waived. Ramp Checking is a First Internet Bank of Indiana deposit account (“Ramp is not a bank”).

Finding 03

Brex starts from the corporate card and global spend

Brex’s pricing page lists Essentials at $0 per user per month, Premium at $12, and custom Enterprise pricing. Essentials covers up to two entities (one global); multi-entity across the US and other countries is in Premium, and local card issuance and reimbursements across more entities move to Enterprise. The page advertises local-currency cards and billing in 50+ countries.

Brex also has a business account: checking provided by Column N.A., up to $6M of FDIC coverage through a sweep of partner banks, and a treasury product that is a government money market fund offered through Brex Treasury LLC, a broker-dealer. Brex says it charges no transaction fees on wires, ACH, or checks from the business account; its fee page lists an FX rate markup of up to 3%.

Eligibility has also moved since the Brex many founders remember. In 2022 Brex stopped serving many smaller, unfunded businesses (independent report). Its current requirements list a minimum cash balance of $50,000 for funded companies, and a Commercial segment for companies with more than $500k in annual revenue.

Brex is now part of Capital One. Capital One completed its acquisition of Brex on April 7, 2026, and says Brex’s CEO continues to lead it. Buyers evaluating Brex should account for the change when considering underwriting, banking relationships, product roadmap, and vendor concentration. Buyer Eval does not assume the acquisition itself is an advantage or a disadvantage.

Finding 04

Is Ramp or Brex better for a startup? It depends which layer you want to consolidate

There is no universal winner here, and this table is not one. It is a decision map: start from the problem you are consolidating, then verify the specific items that the evidence shows can change the answer.

Claims vs. evidence

What the claims actually look like when you check them

9 claims checked: 2verified, 6qualified, 1unknown. The colour marks evidence status, not product quality. Vendor statements are first-party evidence.

  • Verified Enough supporting evidence exists.
  • Qualified Directionally true, with a material limitation: a tier, an add-on, a fee, an eligibility rule.
  • Unknown Part of the claim checks out; the part that matters cannot be assessed from public sources.
Claim Status Evidence basis What the evidence says
Mercury Core banking account at $0/month Qualified Vendor documentation The core account is $0. Reimbursing more than 5 active users a month and enriched NetSuite automations need a paid plan, and Treasury needs more than $250,000 across Mercury accounts.

[1] [2]

Mercury Enriched NetSuite automations on a paid plan “starting at $35/month” Unknown Vendor documentation NetSuite is supported, but the pricing page is inconsistent about where: the FAQ says paid plans “starting at $35/month” (Plus, billed monthly), while the plan grid lists “NetSuite categorizations” under Pro. Which tier this scenario needs cannot be settled from public pages.

[1]

Mercury IO card limits based on your balances Verified Vendor documentation Mercury documents that limits are based on balances at Mercury and on linked external accounts, and that the full balance is paid each period (30-day terms once balances reach $15K). Card capacity scales with cash.

[3]

Ramp “Free $0/mo/user” Qualified Vendor documentation Cards, expenses, and core AP are free. Direct NetSuite, Sage Intacct, and Dynamics 365 integrations, multi-entity, and procurement workflows are listed in Plus: $15 per user per month plus an unpublished platform fee. Procurement is also listed as an add-on.

[5] [6]

Ramp “Free, same-day ACH, domestic and international wires” Qualified Vendor documentation Ramp’s fee documentation lists $0.59 per standard ACH (from June 1, 2026), $10 per same-day ACH, $15 per domestic wire, and $20 per international SWIFT USD payment, and says these transaction fees are waived when paying out of the Ramp Checking Account.

[5] [7]

Ramp Reserve cash earns “up to 4.74%” Qualified Vendor documentation Vendor-stated rate for an investment account, net of an advisory fee of up to 0.15%. Ramp says it is not FDIC insured and has a $5,000 minimum. The deposit account pays a lower stated rate.

[9]

Brex Essentials at “$0 user/month” Qualified Vendor documentation Essentials covers up to two entities (one global) and one local card program. Multi-entity across the US and other countries is Premium ($12 per user per month); broader local card issuance is Enterprise.

[12]

Brex “Up to $6M in FDIC coverage” Verified Vendor documentation Documented as coverage through a sweep across partner banks. It applies to deposits; Brex’s treasury option is a money market fund offered through a broker-dealer, which is not a deposit.

[13]

Brex No transaction fees on wires, ACH, or checks Qualified Vendor documentation No per-payment fees from the Brex business account. The same fee page lists an FX rate markup of up to 3%, and global reimbursements use a Brex-set FX rate.

Decision implications

What this means for the buying decision

  • Decide which layer you are consolidating

    Banking, spend control, and card-led global operations are different jobs. Pick the job first; the vendor choice follows, and the “verify” column above tells you what to check.

  • Price the tier you will actually need, not the free one

    For a 50-person company, the tier lines that matter are reimbursements (Mercury), ERP integrations and multi-entity (Ramp), and entity count (Brex). Two of the three paid prices depend on headcount, and Ramp’s platform fee is not public, so get it quoted.

  • Model costs by funding method

    Ramp’s Bill Pay fees depend partly on whether payments are made from Ramp Checking, and all three vendors’ card limits lean on the cash you hold. Model the cost with operating cash in its current bank and with it moved.

  • A yield headline is an investment decision

    The advertised treasury rates at Mercury, Ramp, and Brex are advisory accounts or money market funds, not FDIC-insured deposits, and each has its own minimum or eligibility rule. Treat them as a treasury-policy question, separate from the card choice.

  • Account for ownership and charter changes

    Capital One completed its acquisition of Brex on April 7, 2026, and Mercury has conditional approval for its own national bank charter. Neither is an advantage or disadvantage on its own. Both are reasons to ask how underwriting, banking relationships, and the roadmap may change during your contract.

Before you buy

What you need to get answered before you buy

Sorted by how much the answer could change the decision.

  1. What would each product actually cost this company over 12 months?

    Critical
    Why it matters
    Published prices are per user, per plan, or per payment, and each vendor’s free tier ends at a different line. List prices do not compare until they are priced against your headcount, entities, and payment mix.
    What we checked
    All three pricing pages, Ramp’s Bill Pay fee schedule, and Brex’s cost page. Ramp’s Plus platform fee is not published.
    Who should answer it
    Each vendor’s sales team, quoting the same scenario: headcount, entities, monthly bills by payment type, and where operating cash will sit.

  2. Which capabilities require paid tiers or add-ons for this company?

    Critical
    Why it matters
    Reimbursements (Mercury), NetSuite and multi-entity (Ramp, Brex), and procurement (Ramp) sit behind paid plans. Mercury’s own pricing page disagrees with itself on the NetSuite tier.
    What we checked
    Plan grids and help-center pricing pages for all three.
    Who should answer it
    Mercury (NetSuite tier), Ramp (what Plus and the procurement add-on include), Brex (which tier covers your entity structure).

  3. How do credit underwriting and limits differ for this business?

    Important
    Why it matters
    All three lean on cash. Ramp asks for at least $25,000 in a linked US bank account; Brex lists a $50,000 minimum for funded companies or a revenue path; Mercury ties IO limits to balances. The limit you get may depend on moving cash.
    What we checked
    Published eligibility and limit pages for all three. Actual limits are not published.
    Who should answer it
    Each vendor, with your real balances and revenue, in writing before you migrate.

  4. Which international capabilities work in the countries this company actually operates in?

    Important
    Why it matters
    Brex advertises local-currency cards in 50+ countries but gates entities by tier; Mercury charges 1% on non-USD wires; card FX fees for Ramp and Mercury were not stated on the pages we checked.
    What we checked
    Brex pricing and global reimbursements pages, Mercury pricing, Ramp pricing.
    Who should answer it
    Each vendor, per country: card issuance, reimbursements, local payouts, and the FX rate or markup applied.

  5. How deep are the NetSuite (or other ERP) workflows?

    Important
    Why it matters
    Ramp documents NetSuite OneWorld multi-entity and multi-currency sync on Plus; Mercury lists NetSuite categorizations; depth of sync (bills, vendors, subsidiaries, custom fields) decides how much manual work remains.
    What we checked
    Ramp’s NetSuite page, Mercury’s pricing and Bill Pay pages. We did not test an integration.
    Who should answer it
    Your controller or NetSuite admin, with a live demo against your chart of accounts and subsidiaries.

  6. If banking and spend move to one vendor, what operational and counterparty trade-offs does that create?

    Important
    Why it matters
    Consolidation reduces tools but concentrates cash, payments, and cards with one provider. Banking at all three runs through partner banks, and in 2026 Brex became part of Capital One while Mercury moved toward its own charter.
    What we checked
    Partner-bank disclosures for all three, Capital One’s acquisition announcement, independent reporting on Mercury’s charter.
    Who should answer it
    Your finance lead, with each vendor’s written answer on partner banks, sweep coverage, and what, if anything, changes for customers as Brex operates within Capital One or if Mercury’s charter is finalized.

Quick answers

Questions buyers ask

Short answers from the evidence above, as of September 28, 2026.

Is Ramp or Brex better for a startup?

It depends on the job. Ramp is built around spend control and AP automation, with direct NetSuite and multi-entity support in its paid Plus tier. Brex is built around the corporate card and global spend, with multi-entity in Premium ($12 per user per month) and broader local card issuance in Enterprise. Brex lists a $50,000 cash minimum for funded companies; Ramp asks for at least $25,000 in a linked US bank account. Figures checked September 28, 2026.

How is Mercury different from Ramp?

Mercury starts from the business bank account and layers cards, bill pay, and treasury on top. Ramp starts from spend management and AP and added banking later. Mercury’s free plan reimburses expenses for up to 5 active users a month; Ramp’s free tier includes cards and expenses but puts direct ERP integrations in Plus. Figures checked September 28, 2026.

Does Ramp charge Bill Pay fees?

It depends partly on the funding method. Ramp publishes transaction fees of $0.59 per standard ACH, $10 per same-day ACH, $15 per domestic wire, and $20 per international SWIFT payment, and says eligible transaction fees are waived when payments are made from Ramp Checking. Checked September 28, 2026.

Is Mercury a bank?

Not yet. Mercury describes itself as a fintech company, not an FDIC-insured bank, with banking services through Choice Financial Group and Column N.A. Independent reporting says the OCC conditionally approved a national bank charter for Mercury, with further FDIC and Federal Reserve approvals required.

Methodology

How this evaluation was made

  • Buyer Eval uses vendor documentation, public pricing, vendor AI agents where available, independent sources, customer evidence, and buyer-provided material.
  • Vendor statements are treated as first-party evidence. A vendor's claim about a competitor is a claim to check, never evidence.
  • Having a Salespeak Company Agent does not increase a vendor's rating or evidence status.
  • This public report uses public sources only. No buyer-provided material, quotes, or trials were available, so anything that depends on them is listed as a question.

Status definitions

What each status means

  • Verified Enough supporting evidence exists.
  • Qualified Directionally true, with a material limitation: a tier, an add-on, a fee, an eligibility rule.
  • Contradicted Credible evidence materially conflicts with the claim as a buyer would read it.
  • Unverified The vendor makes the claim; we looked and did not find enough corroboration.
  • Unknown Part of the claim checks out; the part that matters cannot be assessed from public sources.
