An enquiry that waits two days often becomes a client of another firm. A simple routine helps.
Same-day first response
Decide who answers new enquiries and by when. A short acknowledgement that someone will call is better than silence.
Run the conflict check before the consultation
Check the person and the other parties against existing clients before you discuss the facts in detail.
Record the outcome
Mark each lead as contacted, qualified, converted or not a fit. After a few months you will see which practice-area pages bring the matters you want.
