Will your revenue repeat? The five states every customer is in

Total revenue can look steady while the customers behind it are quietly changing. Sorting customers into five states shows whether your revenue will repeat, and it takes an afternoon.

1. The problem: turnover hides the slide

A flat sales line says little about repeat revenue. A new customer can replace a lapsed one in the totals, even though the two have very different futures. The costly movement is the quiet one: a customer who still orders, but a little less each quarter.

Costs make that slide harder to afford. In August 2026, input prices for UK manufacturers rose 6.1% year on year, while factory gate prices rose 3.7%, according to the ONS Producer price inflation bulletin. When costs grow faster than prices, each lost pound of volume takes more profit with it than it did a year ago.

2. The authority: the squeeze is broad, and money is not cheap

The Bank of England holds Bank Rate at 3.75%, with the next decision due on 5 November 2026. Holding stock and waiting for payment both cost real money at that rate.

Make UK's Manufacturing Outlook 2026 Q3 reports that employment, energy and input costs are squeezing margins, and that although orders have improved the recovery remains fragile. The same logic applies to any small or mid-sized business: a fragile recovery rewards the owner who knows which customers will reorder.

3. The solution: five customer states

Take the last 12 months of sales and place every customer in exactly one state:

• New: first order within the period.
• Growing: spending clearly above the prior period.
• Stable: spending within a narrow band of the prior period.
• Slipping: still buying, but spending clearly below the prior period.
• Lost: no order for longer than their normal buying cycle.

For illustration, take 40 customers and £2.0m of annual sales (illustrative figures). If 9 slipping customers bought £600,000 last year and are now running 25% lower, that group alone represents £150,000 of revenue at risk, a figure no total-turnover report will show.

Tips and tricks for this week

1. Export the last 12 months of sales by customer, and the 12 months before it.
2. Assign each customer one of the five states, using a simple rule for "clearly" such as plus or minus 15%.
3. Add up the revenue in the slipping group and compare it with your net profit.
4. Choose three slipping customers and ring them this week, asking what has changed.
5. Write the rule down and repeat the review every quarter, so the count is comparable.

4. The authority: why this approach works

The principle is old and well documented: keep the right customers. In the Harvard Business Review, Amy Gallo notes that acquiring a customer is "anywhere from five to 25 times more expensive" than retaining one, and cites Frederick Reichheld of Bain & Company finding that a 5% rise in retention can lift profits by 25% to 95%. The range varies by industry, so treat it as a direction rather than a forecast. Sorting customers by state is simply the cheapest way to see where retention is being lost.
