Grasshopper is a virtual phone system — not a full cloud PBX — designed for small businesses and solopreneurs who need a professional business number that rings their existing cell phones. For a one-truck HVAC operator or a two-person father-son shop, Grasshopper provides a toll-free or local number, an auto-attendant greeting, voicemail transcription, SMS, and virtual fax, all without buying new hardware or hiring a phone admin.
Pricing is unusually simple for the category. True Solo starts at $14/month with annual billing and includes one phone number and three extensions. Solo Plus at $25/month annual adds more numbers and extensions, and Small Business at $80/month annual provides unlimited extensions and multiple numbers — critically, all plans include unlimited users at a flat rate, so adding seasonal help during peak HVAC season does not raise your bill. Every plan includes mobile and desktop apps, VoIP and Wi-Fi calling, custom greetings, call forwarding, and voicemail-to-text.
Grasshopper is deliberately narrower than UCaaS platforms like 8x8 or GoTo Connect. It does not offer contact-center queues, supervisor analytics, call recording (standard), or native FSM integrations, and it does not pop customer history into a dispatcher's screen. The tradeoff is simplicity: a solo HVAC tech can set up a professional business line in an afternoon, keep their personal cell as their everyday phone, and never miss a service call because the auto-attendant covers them. As shops grow past a handful of seats and hire office CSRs, most upgrade to Housecall Pro Voice, Workiz Phone, or a dedicated UCaaS provider.
