How Much Does
Business VoIP Cost?
Business VoIP typically costs $20–$50 per user per month. But what's actually included varies dramatically between providers. This guide breaks down the real cost — and how to avoid paying for features you already have or missing features you actually need.
Quick Answer
Business VoIP costs $20–$50 per user per month for most providers. Zonitel ranges from $20–$30 per user/extension each month, depending on team size. There are no setup fees or annual contract; usage-based services and optional products may be billed separately. A 30-day free trial is available.
What Affects the Cost of Business VoIP?
The advertised price is rarely the full picture. Here are the 6 factors that determine what you'll actually pay:
Number of extensions/users
Most providers charge per user or per extension. The more team members, the higher the monthly cost. Look for providers that offer volume discounts.
Features included vs. add-ons
Some providers advertise low base prices but charge extra for call recording, auto attendant, SMS, fax, and analytics. Always check what's included before comparing prices.
Contract length
Annual contracts typically offer lower monthly rates but lock you in for 1–2 years. Month-to-month plans offer flexibility at a slightly higher rate.
International calling
If your business makes international calls, check whether they're included or billed per-minute. Domestic US and Canada calling is typically unlimited on all plans.
Number of phone numbers
Most plans include 1 local number per extension. Additional local, toll-free, or vanity numbers may cost extra depending on the provider.
Setup and porting fees
Some providers charge one-time setup fees or number porting fees. Zonitel charges no setup fees and porting your existing number is always free.
