Your first financial system: accounts, records, and a monthly rhythm

Create clean boundaries

• Decide, with a professional, whether the books will run on the cash or the accrual method. The choice affects when income and expenses are recorded, is reflected on the first return, and is not casually changed later.
• Use dedicated business banking and payment accounts. If the business is an LLC or a corporation, keeping business and personal money separate is not a preference, because commingling weakens the legal separation the entity is meant to provide and makes every later reconstruction harder.
• Document how owners contribute or withdraw money.
• Choose a consistent method for retaining receipts, invoices, contracts, and statements, and confirm how long each type must be kept. The IRS periods vary by record type, and employment tax records run longer than the general rule.
• Limit system access and keep a current list of authorized users.

Design the monthly close before the month gets busy

Decide who gathers statements, records revenue and expenses, reconciles accounts, resolves open questions, and reviews the reports. A calendar and clear ownership matter more than a long software feature list.

Know what the records should answer

At minimum, owners should be able to discuss revenue, major expenses, cash, amounts owed by customers, bills and debt, payroll obligations, and upcoming taxes. The right level of detail depends on the business.
