How much does UCaaS cost per user?

Atlantech's UCaaS page shows a Business Line and a Premium Line, each labeled "Starting At." Nextiva's pricing page shows Core and Engage, with a third plan, Scale, at $75 per user per month. Scale adds contact-center functions such as skills-based routing and AI transcription, so it's priced for a different job than a staff phone line. Microsoft sells calling as an addition to Teams, and its price sits in the same range.

A per-user price only means something beside the list of what the user gets, and UCaaS covers more than a phone line. Atlantech's $12 Business Line is a calling line. Its card lists features such as call forwarding, transfer, hunt groups and call park, with unlimited local and domestic long-distance calling. The $18 Premium Line card lists voicemail, conferencing, collaboration and a softphone.

Nextiva's $15 Core card lists voice, business SMS, video meetings, screen and file sharing, call routing, team chat and a mobile app. Moving to Engage at $25 raises the text allowance from 100 to 500 messages per user per month, and adds a toll-free number with minutes and advanced reporting. CRM integration is marked as an add-on on every Nextiva plan, so a higher tier doesn't buy it.

So the step from one price to the next is mostly a step in features. Settle which features the team can't work without first. Once you know that, you know which plan you're pricing.

The second thing a published price depends on is the agreement behind it. Nextiva's $15 and $25 are annual small-business pricing. They apply to new customers with 1 to 100 employees who sign a paid agreement of 12 months or longer. The published rate comes with that minimum term, so a company that doesn't want a 12-month commitment needs to ask what its rate would be. The term is the length of the commitment. How often the bill arrives is a separate detail.

Atlantech's rates work another way. "Starting At" means the figure is the floor for that line. Atlantech sells through a consultation and pricing call, so the rate and the term for your account come from that quote.

Some companies don't buy a UCaaS seat at all. They already pay for Microsoft Teams, which covers meetings and chat, and they add the phone system to it. Microsoft lists Teams Phone Standard at $10 per user per month, paid yearly. Outside calling then comes from a separate carrier. The version with Microsoft's own domestic Calling Plan is $17, paid yearly. Both sit on top of a Teams license.

Atlantech's Operator Connect service advertises its side "as low as $3 per user/month," with unlimited US calling. Suppose a company has Teams licenses that don't already include the phone system, and its operator quote comes in at that floor. It would pay $10 to Microsoft, at the paid-yearly price, and $3 to Atlantech, or $13 per user per month before other charges.

That $13 isn't a clean saving against $17. Microsoft's bundle price includes the required US communication taxes and fees on the calling part, and an operator's quote handles them its own way. What Teams Phone costs covers those components one at a time.

The license is the recurring part of the bill, and a quote can add to it. Nextiva's footnote says some features involve extra setup, licensing or usage fees. Ask whether a quoted rate includes taxes and regulatory fees.

Desk phones are a separate purchase unless the quote includes them. A softphone on a computer or mobile phone needs no handset, which is one reason the softphone on Atlantech's Premium Line matters to the budget.

To turn a per-user rate into a budget, multiply it by the people who need a line, then add those items. Fifty users at these published rates come to between $600 and $1,250 a month before those items.
