The 11 best treasury management software solutions in 2026

Enterprise treasury platforms and built-in startup treasury products, compared on minimums, fees, instruments, and protection — every figure dated.

Treasury management software answers three questions about your company's cash: where it sits, what it earns, and how fast you can get it back. The right tool depends on which kind of buyer you are. Enterprise treasury management systems (TMS) — Kyriba, SAP, GTreasury, and peers on this list — are software layers that connect to banks you already have, priced by quote and built for treasury teams. Built-in treasury products — Rho, Mercury, Brex, and others — hold and invest the cash themselves, priced as a management fee on invested balances, and built for finance teams of one.

For most startups the practical question isn't "which TMS should we license?" — it's "what should our idle cash earn, at what minimum, at what fee, with what protection, and how fast can we pull it back for payroll?" This guide compares both categories on exactly those numbers, every figure dated and sourced. For live yields updated from product data, see our treasury yield comparison.

On those criteria, Rho Treasury is the strongest fit for startups and growth-stage companies: a $50,000 minimum — one-fifth of Mercury Treasury's $250,000 (mercury.com/treasury, as of 08/02/2026) — a management fee of 0.60% stepping down to 0.15% by deposit tier with every quoted yield already net of it, portfolios of 13-week U.S. Treasury Bills and money market funds held in your company's name (SIPC-protected via Apex Clearing Corp. and Interactive Brokers LLC), and settlement back to Rho checking in about two business days — inside the same platform that runs your checking, corporate cards, and Accounts Payable.

Key takeaways:

  • Treasury management software comes in two categories: enterprise TMS platforms (Kyriba, SAP, GTreasury — software connecting banks you already have, quote-priced) and built-in treasury products (Rho, Mercury, Brex — the platform holds and invests the cash, fee on invested balances).

  • Most startups need the second kind: below roughly $100K of investable cash, an interest-bearing savings account does the job; above it, securities-based treasury products earn market rates on T-Bills and money market funds.

  • Minimums are the first filter: Rho Treasury requires $50,000 — one-fifth of Mercury Treasury's $250,000 (as of 08/02/2026). Brex publishes no minimum (verified 08/02/2026).

  • Protection differs by instrument, not by brand: securities products are SIPC-protected, not FDIC-insured; FDIC coverage applies to bank deposits — at Rho, checking is insured to $250K at Webster Bank, a division of Santander Bank, N.A., and savings up to $75M via a 400+ bank sweep network.

  • Read yields by their basis before comparing: money market funds quote a 7-day SEC yield, bond funds a 30-day SEC yield, and T-Bills a rate from an entirely different source — an "up to" headline means nothing without the instrument, the fee treatment, and a date.

  • Liquidity is the hidden spec: fund redemptions typically settle next business day; T-Bill sales in 2–3 business days. If the cash is payroll, that timeline is part of the decision.

What is treasury management software?

Treasury management software automates cash flow, liquidity, investments, and risk management. The best software is fully integrated with banking, accounts payable, expense management, and financial reporting tools.

Looking for current yields? Rates change daily; prose goes stale. Our treasury yield comparison pulls Rho's rates from the same data the product uses, updates with as-of stamps, and shows dated, sourced competitor rates next to them — net of fees, apples to apples.

Startup treasury products compared: minimums, fees, instruments, protection

The enterprise TMS platforms below are priced by quote and evaluated on workflow fit. The built-in treasury products are comparable on hard numbers — here they are, as software: what it takes to start, what it costs, what your cash sits in, what protects it, and how fast you get it back.

How treasury yields are quoted (and how to compare them honestly)

A yield number without its basis is marketing, not information. Three quoting standards apply, and mixing them makes products look better or worse than they are:

  • Money market funds quote a 7-day SEC yield — the SEC-standardized annualization of the fund's past seven days of income, net of the fund's expense ratio. Rho's MULSX, Mercury's JTCXX, and Brex's DGVXX are all quoted this way.

  • Bond funds and bond ETFs quote a 30-day SEC yield — the standardized measure for funds whose share price can move. Rho's Vanguard short-term bond fund and Mercury's MCRYX are quoted this way. A 30-day bond-fund yield usually looks higher than a 7-day MMF yield because it's paid for taking credit and duration risk.

  • Treasury Bills are individual securities, not funds — there is no SEC yield. Rho quotes its T-Bill figure as a trailing 7-day average U.S. T-Bill yield (13-week), source: U.S. Department of the Treasury, with an as-of date.

Then check two more things: is the number net of the program's management fee (every Rho figure is; Mercury publishes net tiers; Brex discloses no separate program fee), and what allocation does the headline assume — an "up to" number that requires 100% of your balance in a bond fund is a different promise than one from a government money market fund. Any provider quoting one big number without the instrument, the fee treatment, the assumed allocation, and a date is leaving out the part that matters.

Every figure in the table above names its basis and its date. When a number here disagrees with a provider's live page, trust the provider's page — that's the standard we hold this page to.

The 11 best treasury management software tools in 2026

Rho cash management dashboard

1. Rho

Rho is a financial operating system that helps businesses boost their profitability. The platform helps by automating treasury management, helping lean businesses generate yield on their cash reserves while maintaining liquidity and security.

Features

Rho offers a comprehensive set of solutions built into our platform that make it easy for companies to achieve this:

  1. Rho Checking Accounts provided by Webster Bank, a division of Santander Bank, N.A., Member FDIC — checking deposits are FDIC-insured up to $250,000 (the standard limit: per depositor, per insured bank, per ownership category).

  2. Rho Savings Accounts give companies access to up to $75M in FDIC insurance per entity via American Deposit Management Co.'s sweep network of 400+ FDIC- and NCUA-insured institutions.

  3. Rho Treasury, our treasury investment service, invests idle cash — held in your company's name — across 13-week U.S. Treasury Bills, the Morgan Stanley Ultra-Short Income money market fund (MULSX), and a Vanguard short-term bond fund, in an allocation you set in 5% increments. Securities are SIPC-protected (up to $500K per client, including $250K cash) via Apex Clearing Corp. and Interactive Brokers LLC — Treasury is an investment product, not a bank deposit, and is not FDIC-insured.

Once onboarded, Rho Treasury clients select a custom investment policy tailored to their businesss unique liquidity and security needs, supported by Rhos in-house investment team.

Diversification was important to us. We looked at three to four different platforms but wanted multiple ways to access our capital, and Rho offered the seamless setup, integration, and treasury we were looking for. Emma Nelson, COO at MUD\WTRRho's platform then actively adjusts customers portfolios of government securities like U.S. Treasuries to earn market rates while monitoring operating account balances and automatically transferring money as needed.

Pros

  • Treasury automation: Whether you are a CFO managing a lean finance team or a 1-person finance org, Rho can simplify and automate most of your treasury processes for you.

  • End-to-end finance: Rho offers treasury management and other capabilities like AP, banking services, expense, and corporate cards all in one platform.

  • Compliance with investment policy: Rho makes sure that your policy is tailored to fit your firms specific cash flow and security needs

  • Investment monitoring: Rho scans the markets and adjusts your portfolio to ensure that your investments are structured for liquidity and yield. That means you won't need to be T-Bill ladder expert to experience the benefits of investing in T-Bills.

  • Bank account monitoring: Rho technology monitors operating account balances and automatically transfers money to your bank account so that you always have enough cash on hand.

Cons

  • Minimum and settlement: the $50,000 minimum means earlier-stage companies can't use Treasury yet (Rho Business Savings is the interest-bearing option below it), and T-Bill sales settle in 2–3 business days — slower than same-day money market fund redemption elsewhere.

Rho also supports flat-file CSV exporting, so you can automatically tailor transaction categorization to your business needs. Read more about our accounting integrations here.

Features

Mercury offers FDIC-insured checking and savings accounts, Mercury Vault, which offers up to $5M in FDIC deposit insurance, and a treasury solution that allows businesses to invest cash in money market funds with lower-risk, high-liquidity portfolios powered by J.P. Morgan and Morgan Stanley.

Pros

  • Mercury Vault product offers up to $5M in FDIC insurance through partner banks and sweep networks.

  • Relatively low minimum Mercury Treasury is currently available to users with account balances over $250K.

Cons

  • Poor customer support: No phone support is offered, chat support is not available on weekends, and reviews indicate customers struggle with customer support responsiveness.

  • Minimum and instruments: Mercury Treasury's minimum is $250,000 — five times Rho Treasury's $50,000 (both as of 08/02/2026) — and Mercury allocates to money market and ultra-short bond funds only, with no direct U.S. T-Bill option. Dedicated support starts at $299/mo (Pro, billed monthly).

  • Point-solution for cash management: Lacks multi-entity support and additional finance capabilities companies may want to integrate with banking, including AP automation and expense management.

Where Mercury wins: it publishes its full net-yield tier schedule with unusual clarity — the transparency standard this category should copy — and its JPMorgan money market option (JTCXX) redeems same-day, faster than a T-Bill sale settles anywhere. Coverage on the banking side is honest and real: up to $5M FDIC via sweep (mercury.com, as of 08/02/2026).

Wrap-Up: Choose the best treasury management software

After reviewing the options, match the tool to the buyer you are. If you run a treasury team across many banks, entities, and currencies, an enterprise TMS like Kyriba or GTreasury earns its quote-based price. If you're a startup or growth-stage company whose real question is what idle cash should earn — with a $50,000 minimum, fees netted out of every quoted yield, U.S. Treasury Bills and money market funds held in your company's name, and cash back in checking in about two business days — that's what Rho Treasury is built for, alongside the checking, corporate cards, and Accounts Payable you'd run anyway. See current rates or talk to us.

FAQs

Software that manages where a company's cash sits, what it earns, and how liquid it stays. It comes in two forms: enterprise treasury management systems (TMS) that connect to your existing banks for forecasting, risk, and payments workflows, and built-in treasury products from business banking platforms that hold and invest the cash directly.

Usually not a dedicated TMS — those are built for treasury teams managing many banks, entities, and currencies, and are priced accordingly. Most startups need the built-in kind: an interest-bearing savings account below roughly $100K of idle cash, and a securities-based treasury product above it, inside the platform that already runs their checking and cards.

A sweep account spreads bank deposits across many insured institutions so more of your cash carries FDIC insurance — it's still a deposit. A treasury product invests cash in securities (Treasury Bills, money market funds, bond funds) held in your company's name and protected by SIPC rather than FDIC. Deposits are insured; securities earn market rates. Compare deposits to deposits and securities to securities.

The software never is — insurance attaches to what your cash sits in. Bank deposits (including sweep networks) carry FDIC insurance; invested cash in T-Bills or funds is SIPC-protected, not FDIC-insured, no matter whose logo is on the dashboard. Check each product's protection line, not the brand's.

A $50,000 minimum, with an annual management fee that steps down by deposit tier — and every yield Rho shows is already net of the fee. There are no platform, per-user, or subscription fees on the Rho account itself. Current rates and the full fee schedule: see the live treasury yield comparison at rho.co/treasury-yield-comparison and rho.co/product/treasury.

At Rho, fund redemptions arrive the next business day and T-Bill sales settle in two to three business days into Rho checking; there are no lockups. Timelines vary by provider and instrument — same-day for some money market funds, longer for bond funds — so match the allocation to when you'll actually need the cash.
