What does one missed call actually cost an accounting firm during tax season?

For Accounting Firms

The direct cost is the lost client opportunity, which for this industry ranges widely by service type: a simple individual return might be worth $300-800 in first-year fees, while a small business client needing bookkeeping, payroll, and tax prep together commonly runs $2,000-8,000 annually, and a business advisory or CFO-services engagement can be $10,000-20,000 or more. Because a missed call gives no information about which category the caller fell into, the expected cost of a single missed call, averaged across a realistic mix of inquiries, is meaningfully higher than most firms assume, especially once you factor in that missed calls are not evenly distributed, they cluster during exactly the weeks when your highest-value prospects (business owners reviewing their finances and deciding whether to switch accountants) are calling around the firms in their area. There is also a compounding cost beyond the single missed call: a prospect who reaches voicemail during tax season rarely waits for a callback, they call the next firm on their list within minutes, meaning a missed call does not just delay revenue, it often hands that revenue directly to a competitor. Multiply this across a typical surge, if a firm misses even 5-10 calls a week during the 12-16 week tax season that would have become clients, at a blended average value of even $2,000-3,000 per new client, that is $60,000-480,000 in annual revenue left on the table over the season, against a Voksha subscription that runs a few hundred dollars a month during the busiest stretch.
