The five numbers every small business owner should check monthly

Running a small business can feel like flying through cloud. There is plenty of data, but no clear instrument that tells you whether you are climbing or descending. The good news is that you do not need fifty metrics. You need five, checked on the same day each month, watched for their trend rather than their absolute value.

1. Net cash flow

Money in minus money out, across the month. If it is positive, you are building a buffer. If it is negative, you are eating into one. This is the heartbeat of the business, and it is the first thing to look at, because everything else is downstream of it.

What to watch: not just whether it is positive, but whether the positive months are getting bigger or the negative months more frequent.

2. Runway

How many months you could survive at your current net burn. Cash divided by average monthly burn. This is your early-warning system — it turns a vague worry into a specific number of months, which is far easier to act on. Below six months, start planning.

3. Gross margin

What is left from each sale after the direct cost of delivering it — materials, subcontractors, payment fees, anything that scales with the sale. Express it as a percentage. A business on a 60 percent gross margin keeps 60 pence of every pound to cover overheads and profit; one on 20 percent keeps only 20 pence and has to sell far more to survive.

What to watch: a margin quietly slipping is one of the earliest signs that costs are creeping or pricing has fallen behind. Catch it early and it is a small correction; catch it late and it is a crisis.

4. Cash conversion days

How long it takes to turn work into money actually in the bank. If your customers used to pay in 30 days and now take 52, your cash is increasingly trapped in unpaid invoices even if sales look healthy. This number rising is one of the most common hidden causes of a cash squeeze in an otherwise profitable business.

A profitable business can still run out of money if it gets paid too slowly. Watch how fast your money arrives, not just how much of it there is.

5. Expense concentration

How much of your spending sits with a single supplier, client, or category. If one supplier is 40 percent of your costs, a price rise from them lands directly on your bottom line with no warning. The same risk applies to revenue: if one client is most of your income, losing them is an existential event, not a bad month. Spread both where you sensibly can.

Turning it into a habit

The numbers only work if you actually look at them. Pick a fixed day — the first working day of the month is ideal — and spend twenty minutes reviewing all five and noting which way each is heading. Write the figures down somewhere you can compare month to month. The comparison is where the insight lives.

The hard part has never been understanding these numbers. It is finding the time to pull them together from a bank statement every month. Fincharta calculates all five automatically and shows you the trend at a glance. Try it free.
