Keeping It Simple
The fastest, simplest ways to grow your business - no jargon, no fluff. Practical strategies that actually work for SME owners in the USA, New Zealand, and worldwide.
Not every customer is good news, even the ones paying on time. Growth-focused SME owners chase more revenue as if all revenue is equal, when a genuine body of research into customer profitability keeps finding the opposite: a small number of customers generate most of the profit, while another small number quietly erase a meaningful share of it.
If your revenue has grown this year and your margin has not moved with it, this is usually where to look first, not your pricing and not your marketing.
The Revenue Mirage
The enemy here is treating every sale as equal because the invoice looks the same. In reality, cost to serve varies wildly between customers, through rush orders, excessive support, custom requests, slow payment and constant renegotiation, and almost no SME tracks cost to serve at the individual customer level. The damage stays invisible inside an otherwise healthy-looking revenue line.
What the Research Actually Shows
A 2014 Accenture analysis of a 5 billion US dollar consumer goods company found that 20 percent of customers generated 80 percent of the company's profit, 50 percent of customers produced zero profit, and 15 percent of customers were actively causing losses equal to 10 percent of total profit. The exact split differs by industry, but the shape repeats constantly across customer profitability studies: a top tier that carries the business, a wide middle that roughly breaks even, and a smaller tier actively eating the gains everyone else is generating.
The Customer Profitability Audit
- 1. List Your Top 20 Customers by Revenue — then re-rank the same list by how much genuine time, support and hassle each one costs you.
- 2. Find the Gap — any customer high on revenue and high on hassle is a candidate for a quiet renegotiation or a respectful exit.
- 3. Price the Service Level, Not Just the Product — rush jobs, custom terms and extra support are a different offer, and deserve a different price.
- 4. Protect Your Best 20 Percent — ask what your most profitable customers actually value, and make sure growth plans do not quietly dilute their experience to chase the other 80 percent.

Why Owners Keep the Costly Customers Anyway
Letting a customer go feels like losing revenue, and revenue is the number everyone watches, while cost to serve is invisible unless someone goes looking for it. The real obstacle is a measurement gap, not a courage gap. Most owners would act immediately if they could actually see which customers were costing them. This is exactly the kind of blind spot an outside set of eyes, with no emotional attachment to any one account, is built to find.
Quick Wins This Week
- Pull your top 20 customers by revenue this year and estimate, honestly, the hours and hassle each one actually costs.
- Flag any customer who is high revenue and high hassle for a pricing or terms conversation this month.
- Ask your three most profitable, lowest-hassle customers what they value most, and protect it as you grow.
Key Takeaways
- Revenue and profit are not the same thing, and a small share of customers can quietly erase a large share of your margin.
- Research on customer profitability repeatedly finds a small top tier carrying most of the profit and a small bottom tier causing real losses.
- Track cost to serve, not just revenue, for your top 20 customers.
- Growth plans that ignore customer profitability can grow revenue while shrinking margin.
If you have never ranked your customers by profit instead of revenue, that is a more valuable hour than your next marketing meeting.
