Nextiva, RingCentral, Ooma Office, Grasshopper, Quo and
UniTel Voice offer different approaches to business calling.
This guide compares options for offices, remote employees,
entrepreneurs and small teams.
Start with the way your business handles calls. An office
replacing a PBX may need desk phones, extensions, call queues
and centralized administration. A solo business owner may
simply need a separate business number, professional greetings
and calls delivered to an existing smartphone.

and Ooma Office belong on the shortlist for office phone
system requirements. Grasshopper, Quo and UniTel Voice

Virtual and App-Based Phone Services for Small Businesses
Compare these services when your priorities are a separate
business number, professional call handling or customer
conversations shared across a small team.
Entrepreneurs and mobile businesses
Grasshopper
Consider for: solo business owners and small teams that
want a professional business number without building
an office phone installation.
Grasshopper focuses on separating business communications
from personal calls and making a small business easier
to reach. Compare its current plans against the number
of people, phone numbers and extensions you need.
What to compare
Business number and extension requirements.
How employees receive calls while working remotely.
Voicemail and business messaging requirements.
Monthly versus annual billing and current trial terms.
Pricing: view Grasshopper's current plan selector for
True Solo, Solo Plus and Small Business pricing,
included numbers and extensions.

handling and collaboration features with the selected
plan. A mobile-focused virtual phone service should
not automatically be treated as a replacement for
every office PBX function.
