VERDICT

Should I use Mercury?

Everything you do with money. All in one place. Apply in 10 minutes for business banking that transforms how you operate. - mercury.com

Worth it. A strong free business-banking pick for US-based startups and small teams that bank fully online. Skip it if you lack a US entity, need branches or cash deposits, or want high-touch support.

Confidence
