vs Five9 - the 50-seat minimum

VICIfast vs Five9: which should you pick?

Five9 publishes $119 and $159 per-seat tiers, includes the dialer in every tier, and states a 50-seat minimum. Pick Five9 for one bundled suite with vendor-run onboarding and 24/7 support. Pick VICIfast if your floor is under 50 seats, or if flat per-server pricing and your own SIP carrier matter more than a bundle.

Five9 is one of the larger established CCaaS vendors. It sells a full contact-centre suite - omnichannel, AI, workforce engagement, adapters into Salesforce and Microsoft Teams - on a per-seat subscription. VICIfast sells managed VICIdial on a server you control, billed per server. Two different purchases, and the seat minimum is what usually decides which one you can actually buy.

Quick summary

What Five9 publishes today

Five9's pricing page lists five bundles. Two carry a number:

• Digital - $119 Monthly/Seat USD, described as "Digital channels only". Voice is marked excluded on this tier.
• Core - $159 Monthly/Seat USD, "All channels with AI essential". Voice, the dialer, recording, and the CRM and UC adapters are all marked included.
• Plus, Pro and Enterprise - "Contact Sales for flexible pricing". Pro and Enterprise are the tiers where QM, WFM and analytics move from excluded to included.

The footnote under the table is the part worth reading twice: "Prices above are per concurrent user and usage-based pricing may apply, with a minimum of 50 seats." Five9 also states it offers "pricing based on concurrent users, named agents or pay per use", so what you are quoted may not be the list price at all.

Two more footnotes matter if you are modelling cost. AI is metered - "3000 minutes per bundled seat + usage". And workforce engagement is "offered on a named-basis. When named seats required exceeds concurrent seats sold, additional sold as add-ons."

Concurrent seats are not headcount. A floor of 70 people working staggered shifts with 50 on the phones at peak buys fewer seats than a 70-seat named licence would. Get your own peak-concurrency number before you compare anything.

VICIfast publishes the whole grid and bills per server, not per seat: Growth is $219/month in the US on a box sized for 25 agents, Pro is $399 at 50, Ultimate is $749 at 100. Adding agents does not change the invoice until you outgrow the hardware. See VICIfast pricing.

Where Five9 wins

• The dialer is in the base price. Unlike several vendors in this category, Five9 marks a dialer as included on every published tier rather than selling outbound as a separate line item. That is genuinely simpler to buy.
• One vendor for the whole stack. Omnichannel, recording, workflow automation, and - on Pro and Enterprise - quality management, workforce management and analytics. Assembling the equivalent around VICIdial is a real integration project you own.
• Nobody on your team needs to be technical. Five9 runs the platform, the telephony and the upgrades. VICIfast gives you root, which is only an advantage if someone wants it.
• Enterprise procurement fits. Signed MSAs, an assigned team, 24/7 support listed on every tier. If your legal and security review needs a vendor of that size, we are not that vendor.
• Choice of workforce-engagement vendor. Five9's footnote names Verint and Calabrio as alternatives to their own WEM, so you are not forced onto one QM tool.
• AI features are bundled with metered minutes, not a separate procurement - AI summaries, live transcription and AI insights appear from the Core tier up.

Where VICIfast wins

• No seat minimum. Five9's published prices come with a stated 50-seat floor. If you run 12 agents or 30, the published number is not a price you can buy. VICIfast's smallest plan is $49/month.
• Flat per-server billing. Growing from 20 agents to 45 does not change your invoice. Per-seat pricing charges you for every hire.
• You keep your carrier. Bring your own SIP trunk - Telnyx, Bandwidth, Skyetel, whoever - and we add nothing to those minutes. Or use VICIfast Voice, our own US termination, from $0.0085/min. Five9's pricing page does not describe bring-your-own-carrier terms; ask them directly before you assume it.
• Root on your own box. Custom AGI scripts, your own cron jobs, direct MariaDB access. Every SSH session is captured as a replayable asciinema cast, which is usually what an auditor actually wanted.
• Your data stays yours. Leads, dispositions and recordings live in a standard MariaDB schema. Dump it whenever you like; there is no export ticket.
• Per-trunk TCPA scrubbing. Bring your own Blacklist Alliance key and set the litigator-scrub mode per outbound carrier - different portfolios under different compliance contracts can scrub differently. See /features/tcpa-compliance.
• You can try it before you talk to anyone. A 7-day trial on the Launch plan, card validated with nothing charged until day 7, and the server is provisioned in about 40 seconds.

The pricing math

Five9's published entry point for a voice floor is the Core tier at $159 per concurrent seat, and the page states a 50-seat minimum - so the smallest published voice purchase is 50 seats:

Three caveats, all real. AI usage is metered on top. WEM is a named-seat add-on when named exceeds concurrent. And carrier minutes sit on both sides of this table - on VICIfast they arrive as a separate invoice from your carrier rather than folded into a seat price.

Five9 prices checked on their pricing page in September 2026. Vendors change pricing and packaging frequently - re-check five9.com/pricing before you build a business case on these numbers.

When to pick Five9

• You need omnichannel, workforce management and quality management under one contract, and you do not want to assemble them.
• Your floor is comfortably above 50 concurrent seats, so the seat minimum is not a constraint.
• Nobody on your team wants root on a dialer, and you would rather the vendor own uptime, telephony and compliance configuration.
• Procurement requires an established vendor with signed MSAs, an assigned team and professional services.
• You want AI summaries, live transcription and agent assist as part of the platform rather than a Phase 2 integration.

If that describes your operation, the per-seat price is buying you something real.

When to pick VICIfast

• Your floor is under 50 agents, or fluctuates enough that a seat minimum is the wrong shape.
• Outbound volume is the whole job - you are buying dials per hour, not a CX suite.
• You already run a CRM you like and do not need another one bundled.
• You want carrier control: pick your SIP provider, switch when rates change, without changing dialer vendors.
• You want to own your data and be able to leave. VICIdial is open source; if you leave us, the dialer comes with you.
• Your team has, or can hire, one person who knows VICIdial.

Migration

There is no automatic export from Five9 into VICIdial's tables, so plan a rebuild rather than a copy:

• Pull your agent list, dispositions and DID inventory from Five9 reports
• Re-create the closer-group and IVR routing structure inside VICIdial admin
• Source your own SIP carrier - the step teams coming off a bundled platform most often forget to schedule
• Export recordings before the contract ends

Most Five9 to VICIfast moves run one to three weeks with both systems live. The step-by-step version - disposition mapping, recording export, the week-by-week parallel-run schedule - is in the Five9 to VICIdial migration guide. Contact us if you want help scoping it. Scoping it costs nothing; a done-for-you migration is a paid add-on, included on the top dedicated plans.

Next steps

• Migrating from Five9 to managed VICIdial - the runbook: what exports cleanly, what you rebuild by hand, and the cutover.
• VICIfast pricing - the published plan grid, billed per server rather than per seat.
• Managed VICIdial hosting - what actually runs on the box, and who keeps it patched.
