Tiered pricing vs flat-rate unlimited — which one wins?
Two pricing models dominate the category in 2026:
- Tiered minutes (Heyfield, Rosie, Goodcall, most others). You pick a plan with included minutes and pay overage if you exceed them. Lower base cost, predictable for stable-volume shops, slightly more anxious for shops with seasonal spikes.
- Flat-rate unlimited (NextPhone at $199/mo). Predictable ceiling regardless of how many calls you take. Better economics if you genuinely use more than ~1,100 minutes a month, worse below that because you're paying for capacity you don't use.
The crossover for typical home service shops is around 1,100 monthly minutes. Below that, tiered wins. Above it, flat-rate wins. A typical 2-tech plumbing or HVAC shop usually lands in the 600-1,200 minute range — close enough to the crossover that the right pick depends on whether your shop has seasonal call spikes (HVAC summer / winter) you want a ceiling against.
What you're actually paying for
Three cost components matter when comparing AI receptionist pricing:
- Per-minute talk time. The dominant cost for AI receptionists. Voice models are billed per second of generated audio, plus the LLM tokens needed to drive the conversation. Vendors mark this up to give you a flat per-minute rate.
- Setup and integration. Most products are $0 to set up — guided wizards, no professional services fee. Premium ServiceTitan-grade integrations sometimes have a one-time setup cost.
- Telephony / Twilio markup. Whoever runs the phone number costs about $1-2/month plus per-minute charges. Most AI receptionists include this in the plan; a few charge it as a separate line item.
The hidden cost of NOT having one
The cost calculation for an AI receptionist isn't “is $99/month worth it?” — it's “is $99/month worth it compared to the revenue I'm losing right now to missed calls?” For most home service shops the answer is overwhelmingly yes:
- Industry surveys put missed-call rates at 27% on average across home services.
- For HVAC during peak season, one published vendor benchmark (NextPhone, 7-month study of 45 contractors) measured a 74% missed-call rate.
- Average ticket sizes range from $165 (locksmith) to $8,400 (roofing) depending on the trade.
- Even a 20% close rate on recovered missed calls yields multi-thousand-dollar monthly upside for typical shops.
Run the math for your specific trade and tech count using the missed-call cost calculator. The result is usually large enough to make the “is it worth $99?” question feel small.
What to ignore in pricing comparisons
- “Per call” pricing. Some traditional answering services price per call rather than per minute. This is hostile to your busy month and benefits the vendor more than you. Per-minute or flat is the modern standard.
- Annual-only contracts. A monthly cost that's only available with annual prepay is just a discount on a sales-driven product. Most credible AI receptionists are month-to-month.
- Setup fees. One-time setup fees over $0 in 2026 are usually a holdover from premium-service pricing. Self-serve products don't need them.
