RingCentral vs Nextiva: 2026 Pricing and AI Compared
RingCentral and Nextiva top most shortlists when a small business replaces its phone system. The sticker prices are close. The contracts, the texting caps and the way each one charges for AI are not.
The quick answer: Pick Nextiva for the lowest entry price, more texts per seat and a phone system that grows into a customer-service suite. Pick RingCentral for reasonable month-to-month pricing, a deep integration catalog and a separate contact center when you need one. If your phone mostly rings with leads who want a quote or an appointment, pick Carly: it answers, books them on your real calendars and logs the call, set up from one prompt in ChatGPT or Claude.
RingCentral vs Nextiva Pricing in 2026
| RingCentral RingEX | Nextiva | |
|---|---|---|
| Entry | Core $20/user/mo annual ($30 monthly) | Core $15/user/mo annual ($23 monthly) |
| Middle | Advanced $25 annual ($35 monthly) | Engage $25 annual ($50 monthly) |

The Ten-Seat Bill
On annual contracts, Nextiva Core is 10 × $15 = $150/month against RingCentral Core at $200. Nextiva Engage and RingCentral Advanced both land at $250.
Month to month, the middle flips. RingCentral Advanced is 10 × $35 = $350; Nextiva Engage is 10 × $50 = $500. Nextiva limits annual small-business pricing to new customers with 1 to 100 employees on a paid 12-month or longer term.
At the top, ten seats of Nextiva Scale cost $750 a month against $350 for RingCentral Ultra, but Scale is a customer-experience platform, not a bigger phone plan.
Then add the AI receptionist: $39 a month on RingCentral, $99 a month on Nextiva, before overage.
Contracts: Both Renew Themselves
RingCentral’s terms auto-renew for the same length as the initial term unless either party gives notice at least 30 days before it ends. A price-increase notice can arrive at that same mark, and ending early means paying the rest of the term. See how to cancel RingCentral.
Nextiva’s terms also auto-renew. On a minimum commitment you owe the rest of the term plus any disconnect fee, and the 30-day money-back guarantee doesn’t apply. Month-to-month cancellations take effect at the end of the first billing period at least 30 days after notice. The pricing page says “Cancel anytime,” so read the order form. BBB and ConsumerAffairs reviewers report unexpected early termination fees.
For both: calendar the renewal date the day you sign, with a reminder 45 days before.
AI Receptionists: Nextiva XBert vs RingCentral AIR
Nextiva XBert answers calls, texts and web chats. Nextiva says it answers questions, qualifies leads, books or reschedules appointments, routes by intent and hands complex issues to your team. It costs $99 a month for 100 conversations, then $0.99 each (calls under 30 seconds don’t count), as an add-on on every plan or standalone, with a 14-day trial and no contract.
RingCentral AI Receptionist (AIR) is a $39 a month add-on to RingEX, or $49 standalone on any phone system. Both include 100 minutes, then $0.50 a minute in 30-second increments, with a 14-day trial. It covers AI phone menus, routing, appointment booking, lead capture with text follow-up, and English and Spanish. More in RingCentral AI receptionist.
The math at 200 AI-answered calls a month:
- One-minute calls: AIR is $39 + (100 extra minutes × $0.50) = $89. XBert is $99 + (100 extra conversations × $0.99) = $198.
- Three-minute calls: AIR is $39 + (500 extra minutes × $0.50) = $289. XBert stays at $198.
Break-even is around two minutes a call. Short calls favor RingCentral; longer intake calls favor Nextiva. In the base plans, RingEX includes an AI assistant for transcripts and notes, and Nextiva keeps AI call notes and summaries on Scale.
Carly answers and books callers on your team’s real calendars during the call, the same way every time. Compare the field in best AI receptionists.
Texting: Nextiva Gives More Per Seat
RingCentral caps texting at 25 texts per user per month on Core, 100 on Advanced and 200 on Ultra. The shared SMS inbox, reply templates and compliance tools are in the Business SMS Booster, a $25 add-on. Texting is off during the trial, carrier (TCR) registration is required, and reviewers often name the 25-text Core cap as a source of surprise overage.
Nextiva includes 100 texts per user on Core and 500 on Engage, with no stated cap on Scale. Team texting is an add-on on Core and included from Engage.
At the same $25 annual seat, Nextiva Engage gives five times the texts of RingCentral Advanced and includes team texting. For a very small texting-first team, Quo Starter is $15 a user annual ($19 monthly); see Quo vs RingCentral. Carly texts from the same number it answers on, with a text back on every missed call.
Nextiva Leans Customer Service, RingCentral Leans Communications
Nextiva builds customer-service tools into the phone plans. Engage adds a toll-free number with up to 2,000 minutes, advanced reporting, live chat, a chatbot, and 30 social media accounts in the shared inbox against Core’s 3. Scale is a full customer-experience platform with blended calling, skills-based routing and journey orchestration. Nextiva’s contact center starts at $75 per agent.
RingCentral keeps RingEX a communications suite (phone, HD video, team messaging, webinars on Ultra) and sells service tools as boosters: the $35 Call Queues Booster, the $25 SMS Booster, and a quote-based Customer Engagement Bundle. RingCX starts at $65 per agent.
A front desk that’s really a small service team fits Nextiva Engage or Scale. Everyone’s calls, meetings and chats in one app fits RingCentral.
Integrations
RingCentral lists over 330 integrations, opens CRM integrations (Salesforce, HubSpot, Zendesk, Microsoft Dynamics) at Advanced, and offers plugins and MCP connectors for ChatGPT, Claude, Gemini and Copilot at no extra cost. It also sells calling for Microsoft Teams. See the Claude and RingCentral setup.
Nextiva includes Microsoft Teams from Engage and marks Salesforce, HubSpot and other CRMs as an add-on on all three plans, with possible extra setup, licensing or usage fees. XBert lists HubSpot, Zendesk, Zoho, ServiceNow and Zapier.
Support Reputation
Nextiva has 24/7 phone, email and chat on every plan, an advertised 4.6 out of 5 Trustpilot score, and 9.0 on G2’s quality-of-support rating to RingCentral’s 8.0. Its BBB complaints are mostly about billing and early termination fees. RingCentral also offers 24/7 chat and phone support, but Trustpilot reviewers describe slow responses and fights over cancelling.
Where Nextiva Pulls Ahead
- Entry price on a 12-month term. $15 a seat against $20.
- Texts per seat. 100 and 500, against 25 and 100.
- Customer-service tools inside the plan. Live chat and a call center without a booster.
- AI for longer calls. Per-conversation XBert pricing beats per-minute billing past about two minutes.
Where RingCentral Pulls Ahead
- Month-to-month pricing. $35 for Advanced against $50 for Engage.

- A cheaper AI receptionist to start. $39 with 100 minutes, plus a standalone version.
- Unified communications. Meetings, webinars and team chat built around the phone.

Carly business setup prompt
Paste this into ChatGPT, Claude or any AI. It walks you through the rest.
Help me connect Carly Teams so I can work with my organization's business texts, phone calls, voicemail and voice/text agents from this chat. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If a step doesn't match what I see, ask me what's on my screen. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Don't tell me it's connected until list_phone_lines works, and if I have several teams, ask which to use. Before sending a text or making a call, confirm the team, recipient and message or task with me. The steps are below.
# Connect Carly Teams to an AI app
> Carly Teams works a team's business phone lines through the team's AI agents: business texts, phone calls, voicemail, the voice and text agents, and the team's CRM.
MCP server: https://carlyassistant.com/team/mcp (streamable HTTP, OAuth)
## Setup
Carly Teams isn't in any plugin or connector directory yet, so it's added as a custom connection by URL.
1. Add Carly Teams:
- ChatGPT: open https://chatgpt.com/plugins, click Add, and choose Create MCP App (not Create plugin or Upload plugin archive). If Create MCP App isn't on the menu, turn on Developer mode first in Settings > Security and login. Name it "Carly Teams" with the description "Work with my team's business texts, calls, voicemail and voice/text agents," paste https://carlyassistant.com/team/mcp as the server URL, choose OAuth, create it, and sign in. Then in the message box open the + menu, choose Developer mode, and pick Carly Teams. No plugin needs to be built, packaged or uploaded.
- Claude (claude.ai, Claude Desktop, or Cowork): Customize > Connectors > Add custom connector, name it Carly Teams, paste https://carlyassistant.com/team/mcp, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly-teams https://carlyassistant.com/team/mcp`, then /mcp, pick carly-teams, and authenticate.
- Codex: `codex mcp add carly-teams --url https://carlyassistant.com/team/mcp`, then `codex mcp login carly-teams`.
- Cursor: add {"mcpServers": {"carly-teams": {"url": "https://carlyassistant.com/team/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly-teams from Customize.
- Muse: a custom connector to https://carlyassistant.com/team/mcp with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly Teams) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/team/mcp, and sign in.
- Grok Bot: a custom remote MCP server named carly-teams at https://carlyassistant.com/team/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly Teams, paste https://carlyassistant.com/team/mcp, pick OAuth, check the box and click Add, then click the Carly Teams card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly-teams at https://carlyassistant.com/team/mcp. It signs in with OAuth.
Sign in with the Carly account that belongs to the organization.
2. Once it's added, the Carly Teams tools show up in the chat, including list_phone_lines. If they don't, turn Carly Teams on for the chat or start a new chat.
3. To check it worked, call list_phone_lines: it returns the teams and phone lines the account can reach. A team with no phone line yet can get one with find_numbers (optionally by area code) and get_number, which may return a checkout link to finish.
4. Something to try first: "Review our missed calls and voicemail and help me reply to customers." Carly Teams also reads and answers business texts, has the team's agent make calls, and edits the voice and text agents. Texts and calls go out at once from the agent's number and can't be taken back. Team permissions apply.
## Email, calendars and workflows
Email, calendars, files, booking pages and workflows are the regular Carly connector, added separately. It's listed in ChatGPT's plugin directory (https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54) and Claude's connector directory (https://claude.ai/directory/carly), and connects anywhere else at https://carlyassistant.com/mcp/. Its setup is https://carlyassistant.com/mcp.txt.Free Zapier-style workflows; AI agents from $35/month. Get started. Considering an answering service instead? Read AI answering service.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
