Frequently asked
Questions about Mercury
How is Mercury FDIC insured if it's not a bank?+
Mercury is a fintech company, not a chartered bank. Deposits are held at FDIC-insured partner banks — historically Choice Financial Group and Evolve Bank & Trust. Mercury also participates in a sweep network that can extend FDIC coverage beyond the standard $250,000 single-bank limit by distributing deposits across multiple partner banks. Verify the current partner-bank structure and FDIC coverage details at mercury.com, as the sweep network and coverage limits can change. Mercury publishes FDIC disclosures in its account terms.
What business types should NOT use Mercury as their primary account?+
Mercury is not the right primary account for businesses that take in physical cash. There is no cash deposit mechanism — you cannot walk into a branch or use an ATM to deposit bills. Businesses with significant cash receipts (retail, food service, service businesses paid in cash, laundromats) need a traditional bank with branch or ATM cash deposit access. Mercury is purpose-built for digital-first operators: funded startups, SaaS companies, e-commerce, professional services billed by invoice or online.
What integrations does Mercury support?+
Mercury has a strong integration story for software-forward businesses. Direct integrations include QuickBooks, Xero, NetSuite, Stripe, and several others. Mercury also provides a developer API for custom financial automation. ACH transfers are free, and domestic wire transfers are free within published limits. International wires are supported at a low per-wire fee. Verify the current integration list and wire fee schedule at mercury.com, as the product evolves frequently.
Is ClearValue Lending affiliated with Mercury?+
No. ClearValue Lending is a small business funding platform — not a bank, fintech, or financial advisor. Mercury is operated by Mercury Technologies Inc. All account terms, partner-bank disclosures, and FDIC coverage details are determined solely by Mercury. Verify current terms at mercury.com before opening an account.
