What to look for in a business bank account in Maine
A business bank account is the foundation of your funding stack. These are the factors that matter most when choosing where to bank.
Monthly fee and minimum balance
Business checking accounts typically charge $0–$30/month, often waivable with a minimum daily balance ($500–$25,000 depending on the bank). Compare the fee waiver threshold against your typical operating balance — some accounts are free at low balances, others require large reserves.
Transaction limits
Many business checking accounts cap free transactions (checks, ACH, teller) at 100–200/month, then charge $0.20–$0.50 per transaction. High-volume businesses (retail, e-commerce) should compare transaction limits carefully.
Cash deposit capability
Digital-first banks (Mercury, Relay, Novo) do not accept cash deposits — use these only if your business has no physical cash revenue. Cash-deposit-heavy businesses (restaurants, retail, laundromats) need a traditional bank with branch or ATM cash-deposit access.
Interest on deposits
Business savings and money market accounts at digital-first banks and some credit unions pay meaningfully higher APY on idle cash than traditional banks. If you maintain a significant cash reserve, compare business savings rates alongside checking fees.
ACH and wire fees
ACH transfers are typically free or low-cost ($0–$1). Domestic wire fees range from $0 (some digital banks) to $25–$40 at traditional banks. International wires run $35–$65 at most banks. If you wire frequently, this cost compounds.
Integration with accounting software
Digital-first banks (Mercury, Relay, Novo) offer native integrations with QuickBooks, Xero, and FreshBooks for automated bank-feed reconciliation. Traditional banks offer this via third-party connectors (Plaid) — the quality varies. If you do your own bookkeeping, account for this time cost.
