The answer, as recorded

The honest answer is that the "best" splits cleanly on one question: **do you handle cash?** If you don't, online-only banks win on fees and features. If you do, you need a branch or an ATM deposit network. Here's who I'd actually name, in order: **1. Mercury - best default for non-cash businesses (software, agencies, consultants, e-commerce)** $0/month, free domestic *and* international USD wires, up to $5M in FDIC coverage via sweep networks, and a genuinely good API if you want to automate reconciliation. Treasury pays up to ~4% on idle cash. Two real limits: **no cash deposits at all**, and it historically doesn't support sole proprietorships - you need an LLC or corp. **2. Relay - best if you run Profit First or juggle multiple accounts** $0/month, up to 20 sub-accounts and 50 debit cards, which makes envelope-style budgeting (taxes, payroll, owner pay) actually practical instead of a spreadsheet exercise. Crucially, **Relay does accept cash deposits** through the Allpoint+ ATM network - the main thing Mercury can't do. This is my pick for established small businesses with a bookkeeper. **3. Bluevine - best if you want yield plus a credit line in one place** Up to 3.00% APY on checking (tiered - read the qualifying conditions, they're real), $0 on the Standard plan, supports sole proprietors and cash deposits, and Bluevine's core business is lending, so a line of credit sits next to your operating account. Worth it if you'll genuinely use the financing; the higher APY tiers require Plus/Premier. **4. Chase Business Complete Banking - best traditional bank if you take cash** $15/month waived with a $2,000 daily balance (an easier bar than most), 100 free transactions, $5,000/month free cash deposits, the largest branch network, and Chase QuickAccept for card payments. The sign-up bonuses are frequently worth $300-$500. Bank of America Business Advantage Fundamentals is the close substitute - $16/month, but 200 free transactions and $7,500 free cash deposits, so if you deposit a lot of cash BofA is arithmetically better; Chase wins on branches and waiver ease. **5. Found - best for freelancers and solo operators** Built around the self-employed: $0 fees, automatic tax set-aside, built-in bookkeeping and invoicing, and it accepts sole props (which Mercury won't). It's the right answer for a one-person business that would otherwise pay for a separate bookkeeping tool. **6. Axos or nbkc - solid fee-free alternates** Both are chartered banks (not fintechs) with $0 monthly fees and unlimited transactions. I'd name these if you want the no-frills fee-free account without buying into a platform. **What I'd tell you to check before signing anything:** most of these "free" accounts still charge for wires, cash deposits above a cap, and international payments. Compare the *full* fee schedule, not the monthly fee. And note that Mercury, Relay, Bluevine, Novo and Found are **fintechs, not banks** - your money sits at partner banks. That's normally fine, but after the Synapse collapse it's worth confirming the FDIC pass-through arrangement is direct. **If you made me pick one without knowing anything about you:** Mercury if you're digital-only, Chase if you touch cash.
