1) Map your real call demand (not your “office hours” guess)
Start by looking at when people actually try to reach you. In accounting, call spikes often happen when clients are stressed: after they open an IRS notice, during payroll runs, or right before a filing deadline. Those calls don’t follow neat 9–5 patterns—many happen early (before work) and late (after work).
Pull the last 60–90 days of call logs from your phone system or Google Voice, plus any missed call notifications. Create a simple sheet with columns: Date, Time, New vs Existing client, Topic (IRS notice, payroll, bookkeeping, tax prep, extension, audit prep), and Outcome (booked, callback, lost). If you don’t know the topic, use your voicemail or call transcripts to label it.
Then group calls into time blocks that match your day: 7–9am, 9–11am, 11am–1pm, 1–3pm, 3–5pm, 5–7pm, 7–9pm. Accountants usually see patterns like: existing clients calling at lunch (11:30–1:30), new leads calling after 5pm, and “urgent” payroll/notice calls first thing in the morning.
Finally, assign dollar value to each call type so you prioritize coverage correctly. Example: a new business tax return lead can be $500–$2,000; monthly bookkeeping is $300–$1,000/month; audit prep can be $2,000–$10,000. A 2-minute call that books a consult is worth more than a 10-minute “quick question” that interrupts a return you’re preparing.
