Choose Mercury if you want free business banking with optional paid workflows and a dedicated relationship manager on its Pro plan; choose Rho if you want invoicing, expense management, and accounting automation without subscription or per-user fees. Both offer business checking, cards, bill pay, and online access. The decision turns on which workflows you need, how you want to pay for them, and where you plan to hold excess cash.

The verdict
Mercury is the better fit for a business willing to pay for recurring invoicing, additional accounting features, or Pro-level relationship management. Rho is the better fit for a team that wants recurring invoices and expense automation without a software subscription, or wants access to a separate savings account with expanded deposit-insurance coverage. Compare the account and treasury terms separately: deposit insurance does not cover either provider’s treasury investments.
