Pricing Comparison
The price difference between Fonio and Smith.ai is the most significant factor in this comparison. Fonio's Solo plan costs €99/month flat with 1,000 minutes included. Smith.ai's pricing is per-call, starting at around $285/month for 30 calls — but most businesses land between $400–$700/month depending on volume and services.
For a business receiving 60 calls per month at Smith.ai's typical rate, that's roughly $500/month. The same business on Fonio pays €99/month. The annual difference: ~€4,800. That delta needs to be justified by measurable business outcomes from the human backup — which it can be in the right context (law firms, high-ticket B2B) but rarely is for general service businesses.
