Does Mercury Treasury work with non-Mercury bank accounts?

No. Mercury Treasury is the cash-management layer inside Mercury: it earns yield, sweeps, and manages liquidity on cash held in Mercury accounts. It is not a multi-bank treasury workstation. If your operating cash is at Chase or your payroll runs through Wells Fargo, Mercury Treasury can't see it. TreasuryFlow connects every bank you have, including Mercury, and gives you a single consolidated cash position across all of them.

Can TreasuryFlow connect to Mercury?

Yes. Mercury accounts connect via Plaid like any other US bank. Most TreasuryFlow customers who use Mercury have it as one of 3–5 bank connections, alongside their operating bank, payroll bank, and any regional accounts. The TreasuryFlow daily digest and 13-week forecast pull from all of them in a single view.

Is TreasuryFlow a Mercury alternative?

No, and that's the point. TreasuryFlow is not a bank or a card; we don't compete with Mercury for your banking relationship. We're the treasury workstation that sits ON TOP of Mercury (and any other banks you use). Most growth-stage CFOs keep Mercury as one of multiple banks; TreasuryFlow consolidates them all.

How is TreasuryFlow's forecasting different from Mercury's IO?

Mercury IO (their AI workspace, launched 2025) helps with workflow inside Mercury: drafting payments, querying transactions, summarizing your Mercury accounts. TreasuryFlow's 13-week forecaster is built specifically for cash-flow forecasting across all your banks: confidence bands, scenario modeling, recurring transaction detection, what-if analysis, daily/weekly cadence. Different jobs.

Why would a Mercury customer add TreasuryFlow?

If Mercury holds 100% of your cash and you don't need a 13-week forecast or Excel export, Mercury alone is plenty. The moment you have a second bank (payroll at Wells, MMF at Fidelity, regional account, credit union), Mercury can no longer give you a true CFO cash position. TreasuryFlow becomes the consolidating layer.

Why CFOs layer TreasuryFlow on top of Mercury

Most CFOs have 3+ banks

Operating account at Mercury, payroll at Wells, MMF at Fidelity, regional bank for the credit line: that’s the modal mid-market stack. Mercury Treasury can only show you one of those four. TreasuryFlow shows all four.

Forecasting is a different job

Mercury IO is great inside Mercury: drafting payments, querying transactions, summarizing your account. It is not a 13-week forecasting tool with confidence bands and scenario modeling. TreasuryFlow is.

Excel CFO workflow

TreasuryFlow exports live multi-bank data into your existing workbooks. Mercury reporting lives in the Mercury web app.

Keep Mercury where it wins

Mercury is excellent for startups and growth-stage operating accounts: slick UX, fast wire times, FDIC sweep, Mercury Treasury yield. TreasuryFlow doesn’t replace any of that; we sit on top, consolidating Mercury alongside your other banks for daily CFO visibility.

Multi-entity without sub-account hacks

Mercury sub-accounts work for simple structures. For PE-backed roll-ups, multi-entity holdcos, family offices, or multi-property real estate, TreasuryFlow’s Reporting Groups give you parent-child rollups across distinct legal entities and bank relationships.

Fractional CFOs love the combo

Fractional CFOs running 6–12 clients can’t standardize all clients on Mercury. TreasuryFlow connects whatever the client uses and gives the fractional CFO one workstation to manage all clients consistently.
