The real cost of DIY
A DIY platform with a $100–$900/month subscription looks cheap. But a production-grade deployment requires:
- 60–120 hours of engineering time to build (≈ $9K–$18K loaded labor)
- 20–40 hours/month of ongoing tuning and operations (≈ $2.4K–$4.8K/month loaded)
- Compliance work yourself (BAA negotiation, SOC 2 attestation, security review)
- Testing, monitoring, and incident response
- Custom integration work for every CRM/EHR/scheduler
All-in real cost of DIY: $30K–$60K in year one for an equivalent deployment, with the team's engineering capacity tied up.
When DIY makes sense
- You have engineering capacity and want to own the IP
- You're building a SaaS that includes voice AI as a core feature
- Your use case is highly bespoke and no agency offers a fit
- You're comfortable handling compliance and operations yourself
When agency makes sense
- You want to ship fast (3 weeks vs 3 months)
- You operate in a regulated industry (HIPAA, FINRA, SOC 2)
- You don't want to add headcount for an ongoing operations function
- You want one accountable partner with named operators
- Missed-call cost is real and you want a paid-back deployment in 60–90 days
Frequently Asked Questions
- Is DIY voice AI cheaper than an agency?
- On the platform fee: yes. On total cost of ownership including engineering and ops time: no — agencies typically come out 30–50% cheaper at higher quality.
- How long does DIY voice AI take to ship?
- 6–12 weeks from start to production-ready, with significant engineering investment. Agency timelines are 3 weeks for standard deployments.
