OnCrew vs Grasshopper
Grasshopper vs OnCrew for contractors: virtual phone system vs AI that actually answers
Grasshopper is a virtual business phone system. It gives your contracting business a number, extensions, and call forwarding so calls reach your existing phones, with plans starting as low as $14 a month. OnCrew is an AI answering service that picks up when nobody on your crew can, captures a contractor-specific intake, and alerts your on-call team for emergencies. They solve different problems.

Why contractors add OnCrew on top of Grasshopper
Grasshopper routes calls; it does not answer them
Grasshopper is excellent at giving a contracting business a polished phone presence: extensions, business number, custom greetings, call forwarding. None of that helps when the crew is under a sink and the phone is ringing. OnCrew is the piece that picks up.
Trade-aware intake for the moments that matter
Grasshopper voicemail captures a name and a number if the caller is willing to leave one. OnCrew asks the questions your dispatcher would: trade, address, problem, what changed, urgency cues. The callback your crew makes is faster because the intake is already done.
Urgent calls do not wait until morning
A homeowner with a gas smell at 11pm should not be sitting in voicemail. OnCrew classifies the call using trade-specific logic and alerts your on-call channel so a human on your team can call back quickly.
Predictable per-call billing for storm season
Grasshopper plans are priced for routing, not for answering. OnCrew per-call billing covers a long contractor intake at the same flat rate as a short one, with $0.99 overage. Storm season does not turn into a per-minute pricing surprise.
Works with the number you already use
If you already run a Grasshopper number, you do not have to give it up. Point your forwarding or busy/no-answer rules at OnCrew. Your line stays exactly where it is; calls that would have hit voicemail get an AI intake instead.
Clean handoff to your team channel
OnCrew delivers structured intake (name, address, problem, urgency cue) plus a transcript into the channel your team already uses for alerts. Your office or on-call tech has the context before they call back.
How OnCrew handles the call your phone system would otherwise send to voicemail
The exact flow that replaces voicemail when Grasshopper cannot find a human to ring.
- 1
Caller dials your business number
Keep your Grasshopper number (or any number you already use). Forward your line full-time, after-hours only, or on busy/no-answer. OnCrew only picks up when your crew cannot.
- 2
AI greets in your business name
The caller hears a clear, conversational greeting in your business name. The AI asks contractor intake questions (trade, address, problem, what changed) and captures the answers cleanly.
- 3
Urgent vs routine triage
OnCrew flags trade-specific emergencies (no heat in winter, gas smell, active leak, sparking panel with burning smell, storm-damaged roof). Routine calls queue for normal follow-up. Urgent calls go straight to your on-call channel.
- 4
Your team takes it from there
Intake plus full transcript lands in the channel you chose (SMS, email, Slack, Telegram). A human on your team decides next steps and calls back. OnCrew does not promise dispatch times or quote jobs.
Why a virtual phone system alone usually leaves contractor calls in voicemail
Grasshopper is a polished product for what it does. You get a business phone number, custom greetings, extensions, business texting, and call forwarding into mobile and desktop apps for as little as $14 a month. For a one- or two-person operation that can pick up between jobs, that combination is genuinely useful.
What it does not do is answer the call when the crew is on a roof, in a crawlspace, or asleep. Grasshopper rings the phones you tell it to ring; if nobody picks up, the caller hits voicemail. Most homeowners do not leave a voicemail. They call the next contractor on the search results page.
The job an answering service is supposed to do
An answering service exists for the moment your phone system runs out of humans. The caller hears a real greeting in your business name, gets asked the questions your dispatcher would have asked, and gets routed appropriately. The contractor gets the intake without having to interrupt a job.
OnCrew runs that step with AI rather than a generalist call center operator. The intake is trade-specific (HVAC, plumbing, electrical, roofing). Urgent calls (no heat in winter, gas smell, active leak, sparking panel with burning smell, storm-damaged roof) get classified and pushed to your on-call channel. Routine calls queue for normal follow-up.
Running Grasshopper and OnCrew together
The cleanest setup for most contractors is to keep your existing Grasshopper number and routing for in-hours team ringing, and point busy / no-answer / after-hours rules at OnCrew. The phone system still handles the "ring the office, then ring my cell" routing you already have. OnCrew handles the calls that fall through.
You do not have to migrate your number, retrain your team, or rework your call flow. The change is in one screen: where Grasshopper sends a call after the last phone rings out.
When Grasshopper alone is still the right pick
If your call volume is low, your team can reliably pick up during business hours, and your buyers are willing to leave a voicemail or call back, a virtual phone system on its own is a reasonable setup at the published $14-a-month starting price.
For most growing contractor shops, especially those running emergency-leaning trades like HVAC, plumbing, and electrical, the missed-call cost is real. OnCrew sits in front of voicemail so calls that would otherwise drop turn into a real intake and an alert your on-call team can act on.

Frequently asked questions
What is the actual difference between Grasshopper and OnCrew?
Grasshopper is a virtual phone system: it gives your contracting business a number, extensions, and call forwarding to your existing mobile or desktop phones. If nobody on your team picks up, the call usually drops into voicemail. OnCrew is an AI answering service that actually picks up the call when your crew cannot, captures a contractor-specific intake, classifies urgent vs routine, and alerts your on-call team. The two are complementary, but they are not the same product.
How does Grasshopper pricing compare to OnCrew?
Grasshopper publishes plans starting as low as $14 a month for its virtual phone system. OnCrew Starter is $49 a month for 100 included calls, Pro is $149 for 400 calls, and Multi-Truck is $349 for 1,000 calls, with $0.99 per call overage. Grasshopper is cheaper because it is a phone routing app, not an answering service. OnCrew is priced as call handling, not phone service.
Can Grasshopper answer calls when my crew is on a job?
Grasshopper forwards or routes calls to the phones you configure. If nobody picks up, the caller hears your custom greeting and goes to voicemail. Grasshopper itself does not answer the call. OnCrew is an AI agent that answers the call, asks contractor intake questions, and sends an alert to your on-call channel so a human on your team can follow up.
Should I use Grasshopper or OnCrew for after-hours emergencies?
Grasshopper alone usually sends after-hours calls to voicemail unless you have a person manning the line. OnCrew is built for after-hours: it picks up while your crew is asleep, asks about the problem, and pushes urgent calls (no heat, gas smell, active leak, sparking panel, storm-damaged roof) to your on-call channel.
Can I use Grasshopper and OnCrew together?
Yes. Many contractors run a virtual phone system for ringing the right team members during business hours and use OnCrew as the after-hours and overflow safety net. Calls that would otherwise hit voicemail get a real intake instead.
How quickly can I switch from Grasshopper voicemail to OnCrew?
Most contractors are live within days. You keep your existing Grasshopper number. Forwarding rules in Grasshopper point at OnCrew either full-time or only after-hours and on overflow.
