Not all your customers are good to have. Some are great. Some actually cost you money. Some are just so-so. Dharmesh Shah has some good ideas on ranking your customers. His post is geared toward software companies. For other types of companies, I would add things like

• do they pay on time
• do they haggle
• do they refer in other business
• are they fun to work with. Yes fun (or other values) are important.

There is no set list of what makes a customer valuable – a lot depends on your goals and your business style. A client who might be great for one law firm, may be terrible for another.

Obviously a lot of this involves judgement  – it’s not all quantifiable – but that doesn’t mean you shouldn’t track it. Before you tell me that’s too much work, let me toss this into the mix. When I wrote the 5 numbers a business owner needs to know, I left one out. Here’s the 6th. How many customers do you need to meet your goals? The fewer you need the less daunting the task of tracking and ranking your customers.

Some service companies need less than 50 clients. They could start from zero and hit that number in a year by making one sale a week. How many does a hair salon need? A lot fewer than a supermarket. Figuring out what that number is, helps you get that many. Ranking them helps you have the right number of the best customers. That will make your business more profitable and more fun. Isn’t that what it’s all about?
