• Unlimited fee-free cash deposits at eligible MoneyPass/Allpoint ATMs — rare among online business checking

Verdict

American Express Business Checking

American Express Business Checking is a single-tier online account issued directly by American Express National Bank — not a fintech wrapper. As of September 2026: $0 monthly fee, 1.30% APY on the first $500,000 per account (up to 10 accounts), standard FDIC $250k with no sweep. Strengths are unconditional $0 fees, decent APY without activity gates, MR on debit spend, QuickBooks, Zelle, and 24/7 support. Weaknesses are no cash deposits, no outgoing international wires, APY/FDIC gap above $250k, and limited multi-user debit tooling. Best for digital firms already in the Amex ecosystem; pair with a branch bank if the business handles cash.

nbkc Business Checking

nbkc Business Account is a single-tier, non-interest-bearing checking at nbkc bank (FDIC #35014) — a real Kansas-chartered bank, not a BaaS fintech. The Nov 15, 2024 fee schedule prices monthly service, OD, NSF, stop payment, and inactivity at $0 with $0 to open. Standout features are unlimited $0 cash deposits at deposit-enabled MoneyPass/Allpoint ATMs, unlimited items, $0 incoming domestic wires, and $5 outbound domestic. Checking yields 0%; park idle cash in Business MMA at 2.75% APY (Sep 2, 2026). Costs appear only for add-ons: ACH origination ($15/mo), scanner RDC ($15/mo), positive pay ($5/mo), Autobooks ($10/mo). Best for cost-conscious and cash-heavy operators who accept weekday support, 4 KC branches, and standard $250k FDIC.
