Nextiva is a business phone and customer experience platform, from $15 a user a month billed annually, with its XBert AI employee at $1.50 per conversation. RingCentral and Google Voice are alternatives if you want a business phone. SalesCloser does a different job: your AI sales team answers sales calls, qualifies the caller and books or transfers the ready buyers to your team, next to the phone system you already have.
Nextiva is a business phone and customer experience platform: calls, video, texting, team inboxes and a contact center, with an AI employee called XBert. Teams looking for an alternative usually want one of two things: a different business phone system, or an AI that holds the sales conversation itself and books the next step.
Here is what Nextiva offers, the main alternatives, and where SalesCloser fits. Competitor details come from each vendor’s own website, checked in November 2026.
What Nextiva offers
Every Nextiva plan includes business phone and team messaging, with unlimited voice and video, business texting, skills-based routing, a basic CRM and ticketing, shared inboxes and AI transcription and summaries. Higher plans add live chat and a chatbot, more texting and inbound 800-number minutes, single sign-on and supervisor monitoring, and a separate contact center line starts at $75 an agent a month. XBert, its AI employee, answers customers, takes actions and routes conversations.
Billed annually, Nextiva lists NEXT Core at $15 a user a month, NEXT Engage at $25 and NEXT Scale at $75 ($23 and $50 billed monthly for Core and Engage). XBert AI is $1.50 per conversation.

Where SalesCloser is different
A phone platform routes each call to the right person or queue. SalesCloser is your AI sales team: an AI agent has the sales conversation itself, qualifies the caller and books the next step with your team.
- It holds the sales call. A SalesCloser phone agent answers calls to your sales line 24/7, asks your qualifying questions, answers from your own knowledge base and books the meeting or transfers a ready buyer to your team.
- It works next to your phone system. Keep Nextiva, RingCentral or Google Voice for your team’s calls, and send sales calls to the agent when your team is busy, after hours or during spikes.
- It talks to website visitors too. A website agent talks to visitors by chat, voice or video, and a demo agent can show your product by screen share or video.
- It can call out. In an outbound campaign, a phone agent calls your list of past inquiries inside your calling hours and books the ones who are ready.
What that looks like: a franchise brand gets calls from people interested in opening a location. The phone agent asks how much they plan to invest, which territory they want and when they hope to open, explains the steps from first call to signing, and books an intro call with the franchise development team for the candidates who fit. General questions from existing franchisees still go to the support queue.
How to choose
- Keep or pick Nextiva if you want phone, texting, team inboxes and customer service on one platform, with an AI employee priced per conversation.
- Pick RingCentral if you want phone, messaging and video meetings for a growing team in one system.
- Pick Google Voice if your team lives in Google Workspace and wants numbers and routing inside Gmail.
- Pick SalesCloser if your calls are sales conversations and you want an AI agent to qualify callers and book or transfer the ready ones. It sits next to your phone system, not in place of it.
What to check before you choose
- Ask what happens to a sales call nobody answers: a queue, voicemail, or a booked meeting.
- Ask what you pay per user and per AI-handled conversation.
- Calling, consent and recording rules stay your responsibility with any vendor.
