Why it matters
A business can have thousands of customers and still depend on one thing: the channel that brings them in. When most sales start from a single ad platform, marketplace, search engine, affiliate, comparison site or referral partner, the business rests on decisions made by someone else. Advertising costs rise, rules change, rankings move and accounts get suspended. When that happens, revenue can fall within weeks, with no second channel ready to take the strain.
This is different from customer concentration. The customers are many, but they come through one door.
A paid channel also carries a cost risk. If the cost of winning each new customer rises faster than what that customer is worth over time, margin shrinks even while revenue holds up. A seller who has recently cut advertising to lift profit can make the figures look better while future sales weaken.
Local and service businesses are not immune. A trades firm that wins most of its work through one lead-generation site or online directory has the same exposure.
Loupe's valuation tool, at its starting settings, reduces the multiple by 10% when more than 50% of revenue or supply depends on a single platform, channel or supplier, and by 20% when it is more than 80%. For ecommerce, the share of revenue from the largest sales channel overlaps with this rule, so only the larger of the two adjustments applies and the same exposure is not counted twice.
Customer concentration describes how much of a business's revenue comes from a small number of customers. The higher it is, the more the business depends on decisions it does not control.
How to spot it
- The listing leads with a single channel, such as a marketplace bestseller badge or top rankings for one search term.
- Analytics show one source behind most visits or orders.
- Most of the marketing budget goes to one platform.
- The cost of acquiring a customer has risen steadily over the last two years.
- Past dips in revenue line up with changes on one platform.
- Email, direct visits and repeat customers make up a small share of sales.
Questions to ask the seller
- What share of revenue and new customers came from each channel in each of the last 24 months?
- How has the cost of acquiring a customer changed on your main channel?
- Which other channels have you tried, and what happened?
- Has any advertising, marketplace or partner account been warned, restricted or suspended?
- Who owns and controls the advertising, marketplace and analytics accounts, and can they be transferred to a buyer?
- How much revenue comes from customers who return directly or through email?
