Most "what does VoIP cost" guides on the internet are written by the providers themselves. The numbers you find are list prices, what a vendor charges a buyer who walks in cold. The numbers below are what actually shows up on contracts we negotiate every week.
The three tiers of VoIP pricing
Almost every business VoIP provider sells along three tiers. The names change but the structure doesn't.
Entry tier: voice + basics
Domestic calling, voicemail, basic mobile and desktop apps, sometimes SMS. The "starter" plan most providers advertise on their homepage. Real-world range:
| Seat count | List price | Negotiated range |
|---|---|---|
| 10–50 users | $25–32 | $18–24 |
| 50–200 users | $22–28 | $16–22 |
| 200–500 users | $20–26 | $14–19 |
| 500+ users | Custom | $12–17 |
Standard tier: UCaaS
Video meetings, integrations with Microsoft 365 or Google Workspace, basic call queues, light analytics. This is where most businesses land. Real-world range:
| Seat count | List price | Negotiated range |
|---|---|---|
| 10–50 users | $32–42 | $24–32 |
| 50–200 users | $28–38 | $22–28 |
| 200–500 users | $26–34 | $19–25 |
| 500+ users | Custom | $16–22 |
Advanced / contact center tier
Skills-based routing, supervisor tools, omnichannel, AI transcription and coaching, advanced reporting. If you have a real sales or support team, you live here.
| Seat count | List price | Negotiated range |
|---|---|---|
| 10–50 users | $45–65 | $34–48 |
| 50–200 users | $42–60 | $30–44 |
| 200–500 users | $38–55 | $26–40 |
| 500+ users | Custom | $22–36 |
What actually moves the price
Seat count
The biggest single lever. Most providers have unpublished discount tiers that kick in around 25, 50, 100, 250, and 500 seats. Sitting just below a tier is the worst place to be, sitting just above it is the best.
Contract term
Going from a 12-month to a 36-month term typically saves 10–18%. Going to 60 months can push another 5–8% on top. Whether that's worth it depends on your appetite for being locked in.
Features you actually use
Every provider has add-ons that look small but compound. Watch for:
- Call recording ($3–8/user/month if not bundled)
- International calling minutes
- Advanced analytics or QM
- SMS volume beyond a base allowance
- Toll-free minute charges
- Premium phone number / vanity number fees
Compliance requirements
HIPAA BAAs, PCI scope, FedRAMP authorization, and state-specific data residency narrow the field fast, and sometimes push you into a higher tier just to access the necessary controls.
Hardware
Desk phones are mostly optional now (everything works on a softphone or mobile app), but if you need physical handsets budget $80–250 per device for SMB/standard, $300–600+ for executive or conference units. Most providers will roll hardware into the contract, sometimes for free with a long enough term.
Hidden costs the front page doesn't mention
Every published "starting at $X" rate skips these. Plan for them.
- E911 and regulatory fees. $1.50–4 per user per month. Not negotiable, but should be itemized cleanly.
- Number porting. Usually free per number but check the contract, some providers charge $20+ per number for non-standard ports.
- Implementation / professional services. Range from free to $5,000+ depending on complexity. Always negotiable.
- Auto-attendant configuration. Free with most. Some bill it per hour after the first hour.
- SIP trunk overage. If you're on a usage-based plan, monitor minutes the first three months.
- Annual price increases. A standard contract permits 3–7% annual uplift. Negotiable down to 0–2% if you ask.
The wholesale-rate gap
When a buyer walks into a vendor cold, they get retail pricing. When a buyer comes through an advisory firm with $100M+ in annual provider spend, they get wholesale pricing. The same plan, same features, same support, typically 15–30% lower.
This is the only reason vendor-agnostic advisory works as a model. Providers pay the advisor a commission out of their own margin to access deals they wouldn't otherwise win on price alone. The buyer pays nothing extra, and usually pays less than they would have on their own.
How to negotiate (if you're going alone)
- Always get quotes from at least three providers before signing one.
- Have a real "BATNA", the deal you'd take if this one collapses.
- Negotiate the multi-year discount AND the annual uplift cap. Most buyers forget the second.
- Ask for the first 30–60 days free as an implementation buffer.
- Get every line item in writing. If it's not in the order form, it doesn't exist.
- Quarter-end and year-end are the best times to close. Providers have quotas.
The bottom line
If you have 25–500 employees and you haven't repriced your phone system in three years, you're almost certainly overpaying. The question isn't whether there's savings on the table, it's whether the savings are worth the switch.
That's what the quote process is built to answer. Honestly. In one business day. With your actual setup, not a generic average.
