Customer Segmentation

Once you have gotten a few customers, you should make it a habit to think strategically. Not all customers are created equal. In fact you will find that 80% of your sales and or profits come from 20% of your customers. A good exercise is to segment or grade your customers.

Write down a list of all your customers. Hopefully you have a list of them in your accounting or customer management system that you could print out quickly. From this list review the clients and grade them on the following.

Sales – How much total sales have they generated this year?

Profit – How much revenue minus expenses have they generated this year? You might not have this information if you have not tracked expenses to specific jobs or customers.

EODB – How easy are they to do business with? Do they generate problems, questions, last minute changes?

A/R – How quickly do they pay their bills? It’s important that they generate revenue, but if you are floating them a loan for the amount due, it is a hidden cost of doing business with them?

Referral – Have they referred additional business to you? Are they willing to give a referral to your new customers if asked?

Ethics – Do they ask you to bend the rules? Do you trust what they say to you or others? It is hard enough staying out of trouble without having a customer push you in the wrong direction.

From these questions you would make a chart like this

You would put in dollar amounts in the Sales and Profit categories. On the other categories you could indicate a grade of A, B, C, or D or rank them 1 to 99.

Finally you would give each customer a final ranking.

  • A for your top 20% of your customers
  • B for your next 20% of your customers
  • C for the next 40% of your customers
  • D for the final 20% of your customers

From there you would craft your marketing and service strategies to

  • Increase business with your A’s,
  • Maintain business with your B’s,
  • Reduce your efforts with your C’s, and
  • Walk away from your D’s.
