Your bank reconciliation report is the foundation. It confirms your actual cash balance matches what the bank shows after accounting for outstanding checks and deposits in transit. Run this at least monthly. If you don’t know your real cash position, every other report is built on shaky ground.

Accounts receivable aging shows who owes you money and how long they’ve owed it. Group invoices by 0-30 days, 31-60 days, 61-90 days, and over 90 days. This report predicts incoming cash. If most of your AR sits in the 60+ day buckets, you have collection problems that will hurt cash flow regardless of how much work you’re selling.

Accounts payable aging shows what you owe vendors and when. Use it to prioritize payments, spot upcoming pressure points, and negotiate timing when needed. Paying vendors too early burns cash unnecessarily. Paying too late damages relationships and vendor credit terms.

The profit and loss statement shows profitability, not cash. A business can be profitable on paper and still run out of cash because customers pay slowly, inventory ties up capital, or equipment purchases hit all at once. Many business owners focus on the P&L and miss cash problems until they’re urgent. Review your P&L alongside cash reports, not instead of them.

A rolling cash forecast projects your cash position weeks into the future. Start with current cash, add expected inflows from AR and anticipated sales, subtract expected outflows from AP, payroll, rent, and recurring expenses. Update it weekly. This is the report that answers “will I make payroll in three weeks?” before it becomes a crisis. For cash flow planning, a 13-week rolling forecast gives you enough visibility to make decisions without getting lost in speculation about the distant future.

The formal cash flow statement breaks money movement into operating, investing, and financing activities. It matters for the big picture and for lenders or investors who want to understand your business. But most small business owners get more value from the simpler reports above for day-to-day decisions.

For small business bookkeeping in MetroWest Massachusetts, we recommend reviewing bank reconciliation and AR/AP aging monthly at minimum. Cash forecasts work best when updated weekly, especially if your business has seasonal swings or project-based revenue where timing matters. The goal is knowing where you stand today and where you’ll be next month before problems sneak up on you.
