Take the average value of a matter of the kind you actually want more of — not a blended figure across the whole practice, because an estate plan, a contested custody matter and a contingency case are not the same number and averaging them tells you nothing useful.
Now the harder figure: how many first-time callers did not reach a person last month. Most firms have never measured it, because the evidence of a missed legal call is precisely nothing. Your phone provider can give you inbound against connected, broken out by hour. Ask for the evenings and weekends specifically — that is where it concentrates.
Multiply, then be pessimistic on purpose. Assume most were unqualified, wrong practice area, or people who were never going to retain. Halve what remains. Whatever survives that is real, and in legal the residue is usually large, because a single retained matter can exceed a year of what answering the phone costs.
There is a second effect that never shows up in that arithmetic and is worth more over a decade. Referral is how most firms actually grow, and referrals come from clients who felt looked after — an impression that begins on the first call, before any legal work has been done. A firm that is reachable at nine on a Sunday evening is remembered as a firm that was there, and that memory is what gets repeated at a dinner table two years later.
One piece of published research is worth knowing here, and worth handling carefully. Harvard Business Review's audit of 2,241 U.S. companies found 23% never responded to an inbound enquiry at all, and that among those that did respond within 30 days the average took 42 hours; a separate study of 1.25 million leads found that firms making contact within an hour were nearly seven times as likely to reach a decision maker as those waiting an hour longer. That research is about web enquiries and outbound follow-up at ordinary businesses. It is not about law firms and not about answering a ringing phone, so treat it as general evidence that responsiveness decides who gets the conversation — not as a claim about legal intake. What it does corroborate is the thing every managing partner has already observed: the caller does not wait.
Against that, answering is billed by the second Megan is actually on a call. A quiet week costs almost nothing. There is no seat to fund whether the phone rings or not, which is what makes round-the-clock coverage arithmetically possible for a two-attorney firm rather than only for the practices with a billboard budget.
Pay As You Go is $29 a month plus $0.88 for each minute Megan spends on calls, with no included minutes. Professional is $199 a month and includes 500 minutes, then $0.45 a minute. Growth is $499 a month and includes 1,500 minutes, then $0.38 a minute. Enterprise is priced by conversation. Every plan includes the entire product — the plans differ by included minutes only — and calls are billed in real seconds, never rounded up to the next minute.
