What it does
Mercury combines business checking and savings with payments, company cards and finance-team controls. Eligible U.S.-registered businesses can use its free core account, while paid plans add invoicing and other services. Banking is supplied by partner banks.
Mercury puts delegated spending beside the business’s bank activity. Permissions determine who can view, move or debit funds; approval flows and card limits help divide responsibility within a team. Accounting connections include QuickBooks, Xero and NetSuite.
Core business banking costs $0 per month, with no required minimum balance, opening fee or overdraft fee. USD ACH payments and wires are free. International payments in other currencies have a 1% conversion fee, and non-USD card transactions carry a 3% conversion fee.
| Plan | Subscription | Main distinction |
|---|---|---|
| Mercury | $0 per month | Core banking and standard invoicing |
| Plus | Paid subscription | Recurring invoices and ACH-debit invoice collection at $1 per transaction |
| Pro | Paid subscription | Relationship manager and ACH-debit invoice collection at $0 per transaction |
Who can apply
The company must be formed in the United States or a U.S. territory and have existing or planned U.S. operations.
