Frequently Asked Questions

Common questions about missed calls and their impact on your business.

Yes. Business owners and individuals often review their finances in the evening and have questions about taxes, bookkeeping, or financial planning. During tax season (January through April), after-hours call volume increases significantly as deadlines approach and clients feel urgency.
The average accounting client pays $2,000 to $4,000 annually for tax preparation, bookkeeping, and advisory services. Clients typically stay with their accountant for 5 to 10 years, making the lifetime value $10,000 to $40,000 per client.
During tax season, after-hours call volume can increase 50% to 100%. Clients with deadline anxiety call evenings and weekends with document questions, filing status concerns, and extension requests. These are high-intent calls that often result in new engagements.
An AI phone agent can answer common tax deadline questions, collect new client information, schedule appointments, confirm document requirements, and handle basic inquiries about filing extensions and payment plans. This frees up accountants to focus on returns during the busiest period.
During tax season, a firm missing 5 to 10 calls per week from potential new clients could be losing $5,000 to $10,000 in annual recurring revenue. Since accounting relationships last years, the cumulative cost of missed calls during one tax season can reach six figures over time.
