Many business owners have more data than they did a few years ago. That does not necessarily mean they have a clearer view of the business.
The POS system has one report. The marketplace has another dashboard. Accounting software has a separate set of numbers, while advertising platforms offer dozens more metrics.
The problem can quickly shift from “not enough data” to “which numbers should I actually pay attention to?”
If you only have a few minutes each week, start with a small group of numbers that is easy enough to review consistently but broad enough to reveal important changes. For many SMEs, Sales, Gross Profit Margin, Cash Position, Number of Orders and Average Order Value provide a useful baseline.

How many business metrics should an owner review each week?

Short answer: not many - but enough to see sales, profitability, cash and purchasing activity.

A Key Performance Indicator, or KPI, is not simply any number the business can measure. It is an important measure connected to an objective or decision. That means there is no single KPI list that works equally well for a restaurant, professional-services firm, online retailer and subscription business. But if you have never run a weekly business review before, a small core set can help you see:

Where sales are going → whether profit is following → what is happening to cash → how many purchases are occurring → and how much each purchase is worth.

That is why the following five metrics are better viewed as a starting point than a fixed formula.

1. Sales / Revenue - How much did we sell this week?

Sales or Revenue is the most obvious starting point because it tells you how much income the business generated from sales during the period. But looking at “this week's sales” in isolation is rarely enough.
Add a comparison such as:

• Previous week
• Four-week average
• Same period last year when seasonality matters
• Target

Suppose weekly sales are THB 120,000. That number means one thing if last week's sales were THB 80,000 and something very different if the business normally generates THB 160,000.

What Sales can tell you: Is the business selling more or less?

What Sales cannot tell you: Are higher sales producing higher profit?

That is why the second metric matters.

2. Gross Profit Margin - How much of those sales are you keeping?

Higher revenue does not automatically mean better profitability.

Gross Profit is Revenue after deducting Cost of Goods Sold or the direct costs associated with producing or delivering the product.
‍Gross Profit Margin expresses that Gross Profit as a percentage of Revenue.

A basic formula is: Gross Profit Margin = (Revenue − Cost of Goods Sold) ÷ Revenue × 100

For example:

Revenue = THB 100,000
Cost of Goods Sold = THB 60,000
Gross Profit = THB 40,000
Gross Profit Margin = 40%

Looking at Margin alongside Sales helps identify situations in which top-line performance appears healthy while the economics underneath are weakening. Imagine Sales increasing 15% because of aggressive discounting while Gross Profit Margin falls from 40% to 28%.

The useful question is no longer simply, “Did sales grow?” It becomes: “Was the growth profitable enough to be worthwhile?”
‍SCORE includes both Gross Profit and Gross Profit Margin among the metrics small businesses can use to monitor performance.

3. Cash Position - How much usable cash do you have now?

Revenue, Profit and Cash are different things.

A business can be profitable on paper and still face a cash shortage because customers have not paid yet, inventory was purchased in advance, or a major bill is coming due.
For a simple weekly review, an owner should at least know:

How much cash is available now, and what significant payments are coming up?

Businesses that need more detail can add weekly Cash Inflow, Cash Outflow and a forward-looking Cash Flow Forecast. The U.S. Small Business Administration emphasises revenue, expenses and cash-flow management as part of managing business finances. SCORE also lists Cash Flow Forecast as a useful small-business metric. The distinction matters because profitability and liquidity are not the same thing.

A profitable business can still become cash-constrained.
‍What Cash Position can tell you: Can the business meet its near-term financial obligations?

4. Number of Orders / Transactions - How many purchases produced the sales?

Imagine Sales are THB 100,000 this week and were also THB 100,000 last week. At first glance, nothing appears to have changed. But suppose last week had 200 Orders while this week had only 125. That tells a different story.
‍

The same level of Sales can come from:

• The same number of purchases at the same value
• Fewer purchases with higher spending per purchase
• More purchases with a lower value per purchase

Number of Orders or Transactions helps break total Sales into behaviour that is easier to interpret. For some business models, Orders will not be the appropriate unit. Consulting, B2B and project businesses might instead use Number of Customers, Deals or Projects.

What this metric can tell you: Is the change in Sales being driven by the number of purchasing events?

5. Average Order Value (AOV) - How much is each purchase worth?

Average Order Value, or AOV, is the average Revenue generated per Order.
The basic formula is: AOV = Revenue ÷ Number of Orders

For example:

Revenue = THB 100,000
Orders = 200
AOV = THB 500

AOV becomes especially useful when viewed together with Orders because the two help explain what is driving changes in Revenue. Suppose Sales increase by 20%. If Orders increased while AOV stayed stable, growth may be coming from transaction volume.

If Orders stayed flat while AOV increased, growth may be coming from higher spending per order, a pricing change or a different product mix. Shopify includes Sales, Average Order Value, Gross Profit and customer-retention measures among examples of ecommerce performance metrics.
One caution is important: a higher AOV is not automatically better.
‍If AOV rises because prices increased while Orders fall sharply, you still need to examine the combined effect on Sales and Margin.

Why should these five numbers be reviewed together?

The value comes less from any single metric and more from the patterns between them. Consider these examples:

Sales ↑ + Orders ↑ + AOV → + Margin →
Growth may be coming from more purchasing activity.

Sales ↑ + Orders ↓ + AOV ↑
Sales are rising because each Order is worth more, but the decline in Transactions may deserve attention.

Sales ↑ + Margin ↓
Check Promotions, Discounts, Product Mix or Cost changes.

Sales → + Cash ↓
Check Inventory, Accounts Receivable, Expenses or Cash Flow timing.

These are questions you would miss by watching Sales alone.

What about Repeat Purchase, CAC and Inventory?

They matter. They simply do not matter equally for every business model.

A business dependent on repeat customers

Consider adding Repeat Purchase Rate or Customer Retention. Sales may look healthy today while the returning-customer base is weakening.

Ecommerce or paid-acquisition businesses

Customer Acquisition Cost (CAC), Conversion Rate or ROAS may deserve a place in the weekly review.

Inventory-heavy businesses

Inventory Level, Stock Days or Inventory Turnover may be more important than one of the core metrics.

B2B businesses offering credit

Accounts Receivable or Days Sales Outstanding may be more critical than AOV.

Subscription businesses

Metrics such as MRR, Churn and Retention may replace some of the baseline measures. The best five numbers therefore do not come from asking:

“Which KPIs are most popular?”

A better question is: “What could go wrong in our business even while Sales still look normal?”

A simple way to review weekly metrics

You do not need a sophisticated dashboard to start. A one-page spreadsheet can work:

Then add one more field: “What needs attention?”
‍Because a useful weekly review should not end with seeing the number. It should end with: “What do we need to do or investigate next?”

Do not overreact to one week of data

Weekly metrics can reveal changes quickly, but a single week may be affected by holidays, promotions, weather, one unusually large order or normal seasonality. Avoid treating every rise or fall as a new trend.
Where relevant, compare:

• Several weeks of history
• Your normal baseline
• Target
• Seasonality
• Unusual events during the period

A change in a metric is a signal to investigate. It is not automatic evidence of cause.

If Sales fall in the same week that advertising spend is reduced, for example, it may be reasonable to investigate a relationship. The chart alone does not prove that reducing advertising caused the decline.

The takeaway: Your five metrics should be a starting set, not a permanent rule

If a business owner has only a few minutes for a weekly review, a practical baseline is:
‍1. Sales / Revenue — How much did we sell?
2. Gross Profit Margin — How much did we keep?
3. Cash Position — How much usable cash do we have?
4. Number of Orders — How many purchases occurred?
5. Average Order Value — How much was each purchase worth?

But the point is not to memorise these five KPIs forever. As the business changes, the metrics should change with it.
A business facing inventory issues should add an Inventory metric.
A business investing heavily in acquisition should watch CAC.
A business dependent on existing customers should monitor Repeat Purchase or Retention.

The more useful principle is: Track few enough metrics that you will actually review them, enough metrics to reveal important changes, and only metrics connected to decisions you are prepared to make.
