Featured answer
Posh Virtual Receptionist is a US-based live answering service starting around $99/month with per-minute billing that ranges roughly $0.83 to $1.99 per minute depending on plan tier. For contractors with predictable steady call volume in the 50 to 100 monthly range, Posh is a workable choice. For contractors with surge patterns (heat waves, freeze weeks, storm cells) where emergency calls run 8 to 12 minutes each, per-minute billing creates invoice volatility and a 3 to 5x cost spike on a surge week. AI-first alternatives like OnCrew use flat per-call pricing ($49/mo Starter, $149/mo Pro, $349/mo Multi-Truck) that does not spike on long calls.
Where Posh is strong
Crediting where credit is due: Posh built a real product with measurable strengths.
- Live human receptionists. Real US-based receptionists answer the call. For customers who specifically want to hear a human voice, this matters.
- Customizable scripts. Posh allows custom intake scripts and warm transfers.
- Stable company. Posh has been operating for years. Account stability is real.
- 24/7 coverage available. Higher tiers offer round-the-clock answering.
For a single-truck shop with steady 50-call-per-month volume, no major surge patterns, and a strong preference for human voice on every call, Posh is a defensible pick.
Where Posh structurally struggles for contractors
The contractor business has specific patterns that interact poorly with per-minute live answering:
1. Per-minute billing on long emergency calls
A real no-heat call in January or a gas-smell call in August often runs 8 to 12 minutes because the receptionist needs to capture safety information, equipment details, occupant context, and access notes. At $0.83 to $1.99 per minute, that single call costs $7 to $24 on Posh. Multiply by 50 emergency calls in a freeze week and Posh's bill for that week alone can exceed $1,000.
2. Surge weeks blow up the invoice
A 4-truck HVAC shop running 35 calls per day will see 100 to 150 calls on a 115-degree day. If average call duration runs 5 minutes during surge and Posh is priced at $1.20/min, that single surge day costs $600 to $900 in Posh fees. Flat per-call alternatives keep the cost predictable.
3. Trade-script depth
Generic virtual receptionist scripts do not ship with trade-specific intake (heat type, equipment age, vulnerable occupants, gas-smell evacuation order, slab-leak vs supply-line vs drain backup) by default. The contractor has to author and maintain that script with Posh's onboarding team.
4. Concurrent surge capacity
When 6 calls land simultaneously during a heat wave, a live receptionist team queues them. Callers in queue hang up at increasing rates after 90 seconds. AI services handle unlimited concurrent calls in parallel.
5. Recording access and cancellation terms
Some Posh contracts include annual commitments with surrender of recordings on cancellation. Always confirm exit terms before signing. Month-to-month with exportable recordings is the bar.
Cost math: 3 contractor call volumes
| Monthly call volume | Posh (est.) | OnCrew | Smith.ai Starter (live) |
|---|---|---|---|
| 50 calls @ 4 min avg | ~$240 | $49 | $293 (30 included) |
| 200 calls @ 4 min avg | ~$960 | $149 (Pro) | ~$765 (incl. overage) |
| 500 calls @ 5 min avg | ~$3,000 | $349 (Multi-Truck) + $99 overage = $448 | $1,500+ |
Posh's per-minute structure means a freeze-week surge week of 200 calls at 5 minutes each ($1.20/min) costs $1,200 in that week alone. OnCrew Multi-Truck includes 1,000 calls a month for $349 flat with $0.99 per overage.
What contractors should compare side-by-side
If you are evaluating Posh, get apples-to-apples answers on these from each option:
- All-in monthly cost at your typical call volume (state the exact volume and average duration)
- All-in monthly cost on a surge week (3x your normal volume)
- Intake script depth (ask for a sample on a no-heat / slab-leak / panel-failure call)
- On-call SMS handoff packet content and timing (sub-90 seconds, full intake with audio link)
- Cancellation terms (month-to-month, exportable recordings)
- Concurrent call capacity during surge (can field 50+ simultaneous calls without queue)
- Per-call vs per-minute (does cost-per-call stay flat regardless of call duration)
How OnCrew compares
OnCrew is an AI-first answering service configured for HVAC, plumbing, electrical, and roofing trades. Trade-specific intake scripts ship pre-configured. Priority-1 SMS handoff to on-call tech inside 90 seconds. Flat per-call pricing: Starter $49/mo for 100 calls, Pro $149/mo for 400, Multi-Truck $349/mo for 1,000. Overage $0.99 per call. Month-to-month with exportable recordings. Unlimited concurrent calls without queue.
For contractors with surge patterns (heat waves, freeze weeks, storm cells) the math favors flat per-call over per-minute live answering on cost predictability. For contractors who absolutely require a live human voice on every call, Posh or Ruby Receptionists remain valid choices.
