Business Checking

No two businesses are alike. At 1st Mariner, no two business checking accounts are alike either. We’ve designed business checking solutions for companies of every size to ensure we have a checking product that fits your specific business needs. Our business checking accounts include:

  • Business 50 Checking: Accounts for small businesses with lower transaction volumes.
  • Business 200 Checking: Accounts for businesses with a modest number of monthly transactions that don’t maintain a high balance from month to month.
  • Business 300 Checking: Accounts for businesses with moderate-to-high transaction volumes that maintain higher month-to-month balances.
  • Commercial Checking: Accounts for businesses with high volumes of transactions that maintain substantial balances.
  • Community Checking: Accounts for nonprofit or charitable organizations, sole proprietors or government entities eligible to earn interest.

IOLTA, MAHT & Client Escrow Accounts

We also offer industry-specific checking accounts such as IOLTA accounts for lawyers and law firms, as well as MAHT accounts for title insurers, agents and attorneys. We’ve designed our client escrow accounts to save you time and money.
