AI Receptionist: Build vs Buy (2026) — Voice Platforms vs Turnkey
Should you build an AI receptionist on a per-minute voice platform (Retell, Vapi, Bland, Synthflow, PolyAI) or buy a flat-rate turnkey product (Rosie, Goodcall, AgentZap, Smith.ai)?

For most small businesses under a few thousand minutes a month, buy wins on total cost of ownership. Here's the honest cost math, the effort and maintenance trade-off, and who each path fits.
