Nextiva sells business phone service two different ways: tiered per-user UCaaS plans for teams that want everything hosted in the cloud, and separately-priced SIP trunking for teams that already own PBX hardware and just need a carrier connection into it. The two price lists don’t map onto each other cleanly, which is where most “Nextiva pricing” confusion starts. Below are Nextiva’s own published numbers, verified directly on nextiva.com as of August 2026, followed by an honest look at where a cloud-only alternative like KrispCall costs less for the common case — and the specific case where staying with Nextiva is genuinely the right call.

Nextiva pricing plans (2026)
Nextiva’s small-business UCaaS lineup is three tiers, priced per user per month, with a steep annual-vs-monthly spread:
- Core — $15/user/mo billed annually (list price around $23/mo month-to-month, per Nextiva’s own comparison). Inbound/outbound voice, business SMS, video meetings, screen/file sharing, call routing, team chat, mobile app.
- Engage — $25/user/mo annually (around $50/mo month-to-month). Everything in Core, plus customer-to-team SMS, a toll-free number with included minutes, advanced reporting, an inbound call center, and live chat/chatbot. This is the tier Nextiva markets as “most popular,” and it’s the one where fax and CRM integration typically get added on.
- Scale — $75/user/mo. Nextiva’s “full customer experience platform” tier: blended voice and web chat, AI transcription and call summaries, skills-based routing, and journey orchestration across channels.
Above the small-business tiers sit Nextiva’s contact-center plans (Essential, Professional, Premium), starting around $75/agent/mo with the two higher tiers quoted only through a sales call — standard for enterprise contact-center pricing across the category, not unique to Nextiva.
Nextiva fax pricing
Fax is not a flat line-item Nextiva prices the same way across every tier. On Nextiva’s own plan comparison, online fax shows up as an add-on capability layered onto the Engage tier and above, rather than something every Core subscriber gets for free. If a fax pricing page is what brought you here, the practical takeaway is: budget for it as an add-on cost on top of your per-user plan price, and confirm the current line-item price with Nextiva sales for your seat count — Nextiva doesn’t publish a flat standalone fax price the way some competitors do.
Nextiva CRM pricing (what’s actually bundled)
Nextiva doesn’t ship a fully native CRM baked into the base per-user price the way the marketing language sometimes implies — what it actually offers is CRM integration (Salesforce, HubSpot, and similar) plus its own lighter contact/reporting tools inside the Engage and Scale tiers. If your team needs deep CRM functionality, you’re either paying for a separate CRM seat and connecting it, or working within Nextiva’s built-in reporting/contact tools, which are real but not a Salesforce replacement. That distinction matters for the “single-contract” argument below.
Nextiva SIP trunk pricing
This is the part of Nextiva’s price list that has no KrispCall equivalent at all, because KrispCall doesn’t offer it. Nextiva sells SIP trunking as a separate product for businesses that already have on-premise PBX hardware and just need carrier connectivity into it:
- Metered plan — $14.95/month plus $0.008/minute, with 100 minutes included. Built for low call-volume lines.
- Unmetered plan — $24.95/month for unlimited nationwide calling, including a toll-free number, with volume discounts at scale.
Both plans include free setup, eight U.S. data centers for redundancy, E911 support, automatic failover, and call detail records. Nextiva itself is upfront that SIP trunking suits low-call-volume teams that want to keep existing PBX hardware; for everyone else, it steers customers toward the hosted VoIP plans above. That’s the real dividing line for this whole comparison: SIP trunking is a bridge product for hardware you already own. If you don’t own PBX hardware, it’s not a cost center you need to solve for at all — which is exactly the position most teams standing up phone service from scratch are in.
Nextiva voip pricing vs. KrispCall: where the cost actually diverges
Nextiva’s entry Core plan at $15/user/mo annually is genuinely competitive on paper. Where the total cost diverges is add-ons and contract shape: fax, deeper CRM connectivity, and advanced call-center features stack on top of the base price as you move up tiers, and the annual-vs-monthly gap (roughly 1.5–2x) is steep if your team isn’t ready to commit to a yearly contract on day one.
KrispCall takes the opposite approach: no on-prem hardware to bridge, no SIP trunking line-item, and no bundled CRM/fax to price separately — it’s a single cloud-only phone system priced per number/user, aimed at distributed teams (including multi-country research offices) that want calling, SMS, and basic call-center features without also managing PBX infrastructure or a fax add-on they may never use. For a team not currently running physical PBX hardware and not shopping for a fax+CRM-in-one-contract deal, that simpler cost structure is usually the cheaper and less operationally complex path.

Who should actually stay with Nextiva
This is not a blanket “switch to KrispCall” page, and being honest about the tradeoff matters more than the affiliate link. Two kinds of teams are genuinely better served staying with Nextiva:
- Teams still running on-premise PBX hardware. If you have physical PBX equipment and need SIP trunk connectivity into it, Nextiva’s metered/unmetered SIP plans exist to solve exactly that problem. KrispCall has no PBX bridge product — it’s cloud-only, full stop. Ripping out working PBX hardware just to switch phone providers is rarely worth it if SIP trunking already does the job.
- Teams that specifically want fax and CRM-adjacent tooling bundled into one vendor contract. If consolidating your fax line and your CRM connectivity into the same monthly bill as your phone system is a real procurement priority — one vendor, one invoice, one support line — Nextiva’s Engage/Scale tiers are built for that. KrispCall doesn’t offer native fax or CRM, so you’d be managing those as separate tools and separate contracts either way.
Outside those two specific cases — no legacy PBX hardware to bridge, no need to bundle fax/CRM into the phone contract — the cost and complexity case tends to favor the simpler, cloud-only option.
Nextiva pricing plans FAQ
What is Nextiva’s cheapest plan?
Core, at $15/user/month billed annually (around $23/month billed month-to-month per Nextiva’s own pricing page, verified August 2026). It covers voice, SMS, video meetings, and team chat, but not fax or CRM integration.
Does Nextiva charge extra for fax?
Yes, in effect — fax shows up as an add-on layered onto the Engage tier and above rather than a flat feature every plan includes for free. Confirm the current line-item price with Nextiva sales for your seat count, since Nextiva doesn’t publish one flat standalone fax price.
How much does Nextiva SIP trunking cost?
$14.95/month plus $0.008/minute (100 minutes included) on the metered plan, or $24.95/month for unlimited nationwide calling on the unmetered plan — both as of August 2026, per Nextiva’s own SIP trunking page. This is a separate product from the hosted VoIP plans above and only makes sense if you already have on-premise PBX hardware.
Is there a cheaper alternative to Nextiva if I don’t need SIP trunking or bundled CRM/fax?
KrispCall is worth comparing directly — its cloud-only model skips the PBX-bridge and bundled-CRM/fax cost entirely, which is exactly the overhead a team with no legacy hardware doesn’t need to pay for.
The bottom line
Nextiva’s tiered UCaaS pricing ($15–$75/user/mo) and separate SIP trunking line ($14.95–$24.95/line/mo) are both verified directly against nextiva.com as of August 2026. If your team is bridging existing PBX hardware or wants fax and CRM bundled into one contract, that’s genuinely what Nextiva is built for, and switching away from it would cost you more than it saves. If neither of those applies, compare the real per-seat cost against KrispCall before renewing at Nextiva’s higher tiers.
