Step 1: Define the business problem
Lead with the problem, not the solution. "We miss 30% of after-hours calls" is a problem. "We need a voice AI agent" is a solution. The problem framing drives every other decision.
Step 2: Estimate the dollar impact
Missed calls × close rate × average ticket value × 12 = annual opportunity. If that number exceeds $30K, voice AI is almost certainly worth deploying.
Step 3: Map required integrations
- Phone system (Twilio, RingCentral, your existing PBX)
- CRM (Salesforce, HubSpot, GoHighLevel, etc.)
- Scheduler (Google Calendar, Outlook, dedicated booking tool)
- EHR/DMS (industry-specific systems)
- Payment processing (if AI takes deposits)
- Notification channels (SMS, email, internal Slack/Teams)
Step 4: Determine compliance posture
- Healthcare: HIPAA + BAA
- Finance: FINRA, FTC Safeguards
- Legal: confidentiality + conflict-check
- General business: SOC 2
Step 5: Pick a category
- Self-service tool ($50–$300/mo): solo, simple flows
- Configured platform ($300–$1,500/mo): small business, standard integrations
- Voice AI agency ($1,500–$5,000+/mo): regulated, integrated, multi-location
- DIY platform: engineering teams owning the IP
Step 6: Run the vendor evaluation
- Real call samples from your industry (not curated demos)
- Verify integration depth with your stack
- Confirm compliance posture
- Validate pricing model (flat preferred)
- Negotiate SLA and termination clauses
- Reference checks with at least 2 production customers
Frequently Asked Questions
- How long does the evaluation take?
- 2–4 weeks for most buyers. Discovery + 3 vendor calls + reference checks + decision.
- What's the most common mistake?
- Picking on price alone. The cheapest tool often costs more in production once you account for missed integrations, compliance gaps, and ongoing operations.
