The Turnover Factor

Human receptionist turnover creates hidden costs that compound over time. Each replacement requires:

• Time to recruit and interview candidates
• Background checks and hiring process
• Training period (2-4 weeks typically)
• Reduced efficiency during learning period
• Potential gaps in coverage

AI systems eliminate turnover costs entirely. Once implemented, they continue operating without replacement needs.

Decision Framework

Choose Human Receptionist When:

• You have complex client interactions requiring judgment
• Personal relationships with callers are critical
• Budget allows for $40,000-$60,000 annual investment
• You need someone for additional office tasks beyond phone answering
• Your call volume is extremely high with complex routing needs

Choose AI Receptionist When:

• Primary need is professional phone answering
• Budget constraints favor lower ongoing costs
• After-hours coverage is important
• Consistency and reliability are priorities
• You want predictable monthly expenses

Implementation Considerations

Human Receptionist Implementation

• Hiring process: 2-6 weeks typically
• Training period: 2-4 weeks
• Full productivity: 6-12 weeks
• Ongoing management required

AI Receptionist Implementation

• Setup time: 24-48 hours typically
• Customization: 1-2 weeks for complex needs
• Full operation: Immediate after setup
• Minimal ongoing management

The Hidden Value of Predictability

AI receptionists provide cost predictability. Monthly fees remain consistent regardless of:

• Economic conditions
• Labor market changes
• Benefit cost increases
• Turnover situations

Human receptionist costs can fluctuate based on market conditions, benefit changes, and replacement needs.

Making the Decision

For most small to mid-size CPA firms, the cost difference is substantial. AI receptionists typically cost 85-90% less than human receptionists when all factors are considered.

However, cost isn’t the only consideration. Some firms prefer human interaction for their specific client base and service model.

Questions to Consider:

• What is your annual phone answering budget?
• Do you need after-hours coverage?
• How important is cost predictability?
• Are your phone interactions routine or highly complex?
• Do you have additional tasks that would justify a full-time position?
