We all have a general sense of where we get our clients. When asked about it over lunch with a colleague, we say, "Oh, I get about half my new business from existing clients" or "I get about a third of it from my networking group." But the fact that the word "about" invariably creeps in as a qualifier is an indication that we don't know the exact answer. At best, we have an approximation. For many of us, it's been quite a while since we examined our list of existing and former clients so we could attribute the sources. Some of us have never done it at all.
Oh, I know. You just haven't had the time. After all, it would take a good twenty minutes to update the list of former clients, and then there's the analysis itself...and you're already late for that lunch.
So, do yourself a favor and look over your client list. Identify the sources of business over the past three years. If you haven't rewarded your top referral sources in a while, send them each a bottle of wine to show your gratitude. And if you got a referral from someone a long time ago and they haven't referred since, take them out to lunch. They've already proven themselves to be a valuable resource. They just need a little more shaking. And they may be a better use of your attention than many of the other lunches you've scheduled into your calendar.
