The scenario and the methodology
The test case is deliberately boring — the modal American small office:
- 10 users, one location, everyone needs a line
- Unlimited US & Canada calling
- Auto-attendant ("press 1 for sales…"), ring groups, business-hours routing
- Mobile + desktop apps
- Voicemail-to-email with transcription
- Call recording
Prices are the providers' published rates as of July 2026, taken at the cheapest tier that actually covers that feature list. Where a required feature is a paid add-on, we priced the add-on in. The "realistic all-in" column adds each provider's own regulatory-recovery and administrative surcharges where they publish them, estimated from their fee schedules and customer reports where they don't. Estimates are marked as estimates — treat them as the center of a range, and get a written sample invoice before you sign anything (that goes for us too).
The master table
| Provider & plan | Headline $/user/mo (annual) | Monthly billing | Contract for headline price | What gets added | Realistic all-in, 10 users/mo (est.) |
|---|---|---|---|---|---|
| voip.army Business | $28 | $34 | None | Nothing — recording, transcripts, IVR included; no regulatory recovery surcharge | $280–340 |
| RingCentral Core | $30 | $35 | Annual typical | Regulatory recovery + admin fees, setup; Advanced tier ($35) for some routing features | $400–450 |
| Nextiva Core | ~$30 | Materially higher | Annual typical | Fees; renewal-year price increases are the recurring complaint | $380–450 |
| Vonage Premium | from $29.99 | Higher | 12 months typical | The add-on lottery: recording, transcripts, and several integrations are paid extras | $420–520 |
| 8x8 X2 | from $24 | — | Annual | Cheap Express tier retired in 2024; X4 at $44 for supervisor features | $320–400 |
| Dialpad Standard | $15 | $23 | Annual for headline | AI features and Pro tier ($25/$35) — real-world reports land near $42/user with the add-ons | $350–420 |
| GoTo Connect Standard | ~$32 (Basic ~$27) | Higher | Annual typical | Fees; Basic tier is missing recording and analytics | $370–420 |
| Ooma Office Pro | — | $24.95 (Pro Plus $29.95) | None | Regulatory fees; hardware upsells; Essentials tier lacks recording | $290–350 |
| Zoom Phone US/CA Unlimited | $15 | — | Annual | Requires a Zoom Workplace seat per user; queues and recording live in add-ons — true all-in usually $30–35+/user | $300–380 |
| Grasshopper Small Business | $55/mo flat (not per-user) | None | Not a PBX: no multi-level IVR, no queues, no desk-phone support — a shared number layer on personal cells | $55, but see notes | |
Published rates as of July 2026. "Realistic all-in" is our estimate for the 10-user scenario including provider surcharges and required add-ons, before state/local taxes (which apply to every provider roughly equally). Full methodology per provider on our comparison pages.
The five fees they don't advertise
1. The regulatory recovery fee
The big one, and the most misunderstood. This is not a government tax — it's a provider-set surcharge, typically $2–6 per user per month, added at checkout to recover the provider's own compliance costs. Because it isn't part of the advertised rate, it can change without notice. On a 10-seat account, this line alone is $240–720 per year. Actual government taxes (state and local telecom taxes, e911) come on top, for everyone.
2. The monthly-billing premium
Nearly every headline price in the table assumes annual prepay. Bill monthly and the same seat costs 15–25% more. That's a fair trade some months — but it means the price you compared in the ad is not the price you'll pay while you evaluate the service.
3. The add-on lottery
Call recording, voicemail transcription, analytics, and CRM integrations each live in a different tier or add-on depending on the provider. Vonage is the canonical example — customers report landing at $52/user after adding what the brochure implied was included. Dialpad's $15 headline reads great until the AI features and Pro requirements push real-world accounts to ~$42/user.
4. The prerequisite seat
Zoom Phone's $15 rate is an add-on price: it requires a Zoom Workplace seat under it. Priced honestly — phone plus prerequisite — you're at $30–35+ per user, which is a fine price, just not $15.
5. The renewal-year surprise
First-year pricing is a promo at several providers. The recurring pattern in customer reports: year-two renewal arrives 10–30% higher, and the discount you signed at is suddenly "no longer available." Nextiva and RingCentral draw the most complaints here. Ask for the year-two number in writing before you sign the year-one deal.
Provider-by-provider notes
One honest paragraph each — the full teardowns live on the linked comparison pages.
- RingCentral — the enterprise-grade reference product. If you need its depth, it's worth it; a 10-person office usually doesn't, and pays $100–150/mo extra for it. Over five years that's $6,000–9,000.
- Nextiva — solid platform, bundles its own CRM. The bill is fine in year one; watch the renewal.
- Vonage — reasonable core, but the add-on pricing model means the brochure price and the invoice diverge more than any other provider here.
- 8x8 — global reach and contact-center DNA. Since the Express tier retired in 2024, there's no true small-office entry point.
- Dialpad — the best AI marketing in the category. Buy it for the AI if you want the AI; don't buy it for the $15 sticker.
- GoTo Connect — competent and unremarkable; pricing lands mid-pack once fees are in.
- Ooma — genuinely SMB-priced and contract-free; the gaps show in routing depth as you grow past a handful of users.
- Zoom Phone — excellent if you already pay for Zoom Workplace anyway; the marginal cost is then honest. As a standalone phone system, price the prerequisite in.
- Grasshopper — a different product category: a business number on top of personal cell phones. At $55 flat it's genuinely cheap, and genuinely not a phone system. Right answer for a solo founder; wrong answer at 10 desks.
- voip.army — our Business plan is $28/user/mo annual, $34 monthly, and the number on the pricing page is the number on the invoice: no regulatory recovery surcharge, no setup fees, recording and transcripts included, month-to-month welcome. That policy is the product.
The 5 questions that surface a true quote
Whoever you're evaluating — including us — these five questions, answered in writing, collapse the fee games:
- "What is the total monthly invoice for exactly N users, with every fee and surcharge included?" Ask for a sample invoice, not a quote.
- "Are call recording, voicemail transcription, and the mobile app included at this tier?" Name each feature; "our platform supports it" is not "included."
- "What will this same service cost at renewal in year two?"
- "Is there a contract, and what does leaving mid-term cost?"
- "What are the one-time charges in month one — setup, activation, porting, e911?"
A provider that answers all five crisply is telling you something about what support will be like. A provider that dodges is telling you something too.
FAQ
Why is my VoIP bill higher than the advertised price?
Four stacking reasons: annual-prepay headline pricing (monthly runs 15–25% more), regulatory recovery and admin surcharges ($3–6/user typical), features sold as add-ons that you assumed were included, and renewal-year increases. A $25 headline routinely lands at $38–45 on the invoice.
What is a regulatory recovery fee?
A provider-set surcharge — not a government tax — recovering the provider's own compliance costs. It varies by provider ($2–6/user/mo), isn't in the advertised price, and can change without notice. Real taxes come on top.
How much should a 10-person office pay in 2026?
$280–400/month all-in for a full-featured system is the fair band. Below that, check what's missing; above $450, check what you're paying for that you won't use.
Is annual billing worth it?
The 15–25% discount is real, but you trade away walk-away leverage and expose yourself to renewal games. If the monthly premium is small, pay it. At 10+ seats, ask for annual pricing on a monthly term — several providers will say yes.
What should I ask before signing?
The five questions above, in writing. The sample-invoice request alone eliminates most surprises.
