Client concentration check
Does one client own your business?
Two numbers from your invoices. Divide one by the other and you have the figure most owners never look at: how much of your revenue walks out the door with a single client.
Your concentration number
How to read it, so you can argue with it: use the same period for every number, a week, a month or a quarter. The readings are a rule of thumb: under 15% is spread, 15 to 25% is worth watching, 25 to 40% is exposed, 40% and over is dependent. A retainer that renews automatically is still one client.
Know the number every week, not the week they leave
Pulling every invoice into one number is scheduled work, and scheduled work is what we build an AskEleven Employee to run: from the books you already keep, on the day you set.
