Business Banking

Business banking encompasses the full suite of financial services a bank or fintech offers to companies: checking accounts, savings accounts, credit lines, merchant services, and treasury tools. Unlike personal banking, business accounts separate company funds from founder finances, which is critical for bookkeeping, tax compliance, and liability protection. Modern neobanks have disrupted traditional business banking by offering faster account opening, API integrations, and fee-free structures tailored to startups.

How it works

A business opens a dedicated deposit account under its legal entity (LLC, corporation, etc.), which establishes a clear money trail separate from personal transactions. Banks assign routing and account numbers that payroll platforms, payment processors, and vendors use to push and pull funds via ACH or wire. Business bank accounts also unlock access to business credit cards, lines of credit, and lending products that use the entity’s financial history rather than the founder’s personal credit.

Key facts

• Separation of funds: Commingling personal and business funds can pierce the corporate veil and expose founders to personal liability.
• Neobank options: Mercury, Relay, and Brex offer FDIC-insured business accounts with no monthly fees and same-day ACH.
• Minimum requirements: Most banks require an EIN, articles of incorporation or LLC operating agreement, and a government-issued ID to open an account.

For builders

For SaaS founders and indie operators, choosing a business bank account early is non-negotiable: investors, payment processors like Stripe, and accounting software like QuickBooks all require a business account to function properly. The choice of bank affects wire fees, ACH speed, and whether you can integrate directly with your financial stack via API. Neobanks often suit early-stage startups better than traditional banks due to lower overhead and faster onboarding.
