Chase charges you $15/mo (waivable) + $25 per domestic wire + $40 per intl wire + $0.40 per transaction over 100. Mercury and Brex charge $0 for all of that. On 4 supplier wires a month, that’s $1,380/yr you keep by not choosing a branch. On 8 domestic + 2 intl, Mercury saves $3,360/yr.

Final Verdict — StackVerdict Pick (October 2026)

STACKVERDICT VERDICT $0 WINS UNLESS YOU NEED BRANCHES

For US startups that never touch cash, Mercury $0 is the rational default — $1,380/yr saved on 4 wires alone, plus $5M FDIC and API. Add Brex at Series A when treasury + cards justify $12/user. Keep Chase only if you deposit cash or plan SBA.

StackVerdict score: Mercury 9.0/10 (free, API) • Brex 8.6/10 (suite, treasury) • Chase 8.2/10 (branches, SBA). Weighted for 2026 US startup intent: $0 with most functionality per dollar.

Methodology: Same LLC account-opening flow compared across 3 banks Sep 2026; wire/ACH fees modeled at 20 wires/40 ACH; API sync to QBO and treasury quotes reviewed from vendor documentation. 2026 Chase fee waive thresholds verified.
