Gross revenue is the KPI that gets reported. It is not the KPI that predicts survival. This post identifies the seven numbers that actually determine whether a small business is healthy, explains how to calculate each one, and describes what to do when any of them moves in the wrong direction.

Small businesses that track the wrong KPIs make expensive decisions with false confidence#
Revenue growth is the number most operators focus on. It is also one of the least predictive indicators of business health. A business can double its revenue while its margin collapses, its cash dries up, and its customer base churns faster than it grows. The operators who spot trouble early are the ones tracking the metrics that precede decline — not revenue, but margin compression, customer retention drop, and cash conversion slowdown. Each of those signals typically appears two to three months before the revenue number turns negative. Tracking the right KPIs means you have time to intervene. Tracking the wrong ones means you discover problems when they are already critical.
KPI 1 and 2: gross margin and net margin#
Gross margin is revenue minus cost of goods sold, expressed as a percentage. A healthy gross margin for retail is 40 to 60%. For services businesses it is typically 60 to 80%. If your gross margin is declining quarter on quarter, either your costs are rising faster than your prices or you are selling more of your lower-margin products. Net margin is revenue minus all costs, including operating expenses, divided by revenue. For small businesses, a net margin of 10 to 20% is sustainable. Below 10%, you have very little buffer for unexpected costs or a revenue dip. Track both monthly. When gross margin falls, investigate cost of goods first. When net margin falls but gross margin is stable, look at operating expenses — usually marketing, payroll, or software costs that have crept up.
KPI 3 and 4: customer acquisition cost and customer lifetime value#
Customer acquisition cost (CAC) is total sales and marketing spend divided by number of new customers acquired in a period. Customer lifetime value (LTV) is average order value multiplied by average purchase frequency multiplied by average customer lifespan. The ratio between them — LTV to CAC — should be at least 3:1 for a sustainable business. Meaning for every pound or dollar you spend acquiring a customer, you should expect to earn at least three back over their relationship with you. Most small businesses do not calculate either number systematically. They know roughly how much they spend on ads. They do not know how many customers that spend produces or what those customers are worth over time. Establishing both numbers takes one afternoon and changes how you allocate marketing budget immediately.

KPI 5 and 6: monthly recurring revenue trend and churn rate#
Even if you do not run a subscription business, you have recurring revenue in the form of repeat customers. The percentage of last month's customers who bought again this month is your effective repeat purchase rate, which functions like a churn metric for product businesses. If 40% of your customers from last month bought again this month, your retention is healthy. If that figure is 15%, you are on a treadmill where you must constantly acquire new customers just to stand still. Track this monthly. A declining repeat rate almost always signals a product quality, customer experience, or pricing problem — and it shows up in this metric two to three months before it appears in your revenue trend.
KPI 7: cash conversion cycle#
Cash conversion cycle (CCC) measures how long it takes, in days, to convert a pound or dollar of inventory investment into a pound or dollar of collected cash. The formula is: days inventory outstanding plus days sales outstanding minus days payable outstanding. A shorter CCC means your business generates cash more efficiently. A lengthening CCC — even one that is still positive — is an early warning that either your inventory is taking longer to sell, your customers are taking longer to pay, or you are paying suppliers faster than before. For eCommerce businesses, a CCC of 20 to 40 days is typical. For wholesale or B2B businesses with invoice terms, 45 to 70 days is common. Anything above 90 days requires active management to avoid cash flow problems.
How to track all seven KPIs without spending hours on reports#
The barrier to consistent KPI tracking for most small business operators is the time it takes to gather data from multiple sources and assemble it into a coherent view. If your sales data is in Shopify, your financial data is in Xero, and your payment data is in Stripe, calculating LTV or cash conversion cycle manually requires pulling from three places and reconciling differences. AskBiz aggregates all of those sources and can calculate any of these seven KPIs on demand in response to a plain-English question. Ask: "What is my customer acquisition cost this quarter compared to last?" and get a specific answer from your actual data. The monitoring is automatic. You spend your time on the decision, not the data gathering.
