What business phones really cost in Cayce - and which bill lines are invented
A phone system quote in Cayce is the easy part - every vendor publishes seat prices. The expensive parts hide in the bill's fee lines and the contract's renewal clause. Verified ranges, South Carolina's rules and the honest decision path are below.
Business VoIP seats quoted to Cayce offices run $15-$30 per user per month at entry tier and $25-$50 at mid tier in 2026 vendor list prices - with annual billing 20-50% cheaper than month-to-month for the same seat.
Taxes and fees commonly add 20-30% to a Cayce business phone bill - and only some lines are government-set: the federal USF runs 38.8% of interstate charges in Q3 2026, while 'regulatory recovery' fees are invented and kept by the carrier.
Most phone contracts offered in Cayce run 12-36 months with an automatic-renewal clause: miss the written-notice window, commonly 30-90 days before term end, and many contracts renew for another full term.
The bill's quiet fact: some fee lines are genuine government charges - the federal USF and your state's 911 surcharge - and some, like 'Regulatory Recovery Fee', are invented by the carrier, set at whatever the carrier chooses, and kept by the carrier. Telling them apart is this site's job.
Every provider on the market runs on the same physics: annual billing beats monthly by 20-50%, contracts auto-renew if you let them, and competing quotes are the only pricing discipline that consistently works.
Every category, priced (2026)
| Phone system category | 2026 published range | The number that actually matters |
|---|---|---|
| Cloud VoIP seat (entry tier) | $15-$30/user/month | Annual billing runs 20-50% cheaper than monthly for the same tier |
| Cloud VoIP seat (mid tier) | $25-$50/user/month | Compare the all-in total with taxes and fees - commonly 20-30% on top |
| Contract term | 12-36 months typical (up to 84) | Miss the 30-90 day notice window and many contracts renew a full term |
| Taxes and fees on the bill | commonly 20-30% of the total | Federal USF (38.8% of interstate charges, Q3 2026) and state 911 fees are government-set; 'recovery' fees are carrier-invented |
| SIP trunking (keep your PBX) | $15-$30/channel/month | Priced per concurrent call, not per user - fits businesses keeping a PBX |
| Desk phones and wiring | $55-$280/phone; $125-$400/cabling drop | 'No upfront cost' plans still need handsets, drops and a PoE switch |
| Legacy analog lines (elevator, fire alarm, fax) | $30-$60/line/month cellular adapter | Copper holdout pricing runs $150-$500+/line - and standard VoIP fails those inspections |
Get competing phone system quotes - it is the whole negotiation
Two free marketplace paths: one form brings back multiple vetted providers who know they are competing for the job. Competing quotes are the only pricing discipline this industry consistently respects.
External links go to the marketplaces' own sites and forms. This site may earn a referral fee at no cost to you - it never changes the data above, and no individual provider pays to appear in our research.
What a fair phone deal includes - and what the padded version sells
A fair deal includes
- The all-in monthly total per user with taxes and fees estimated
- A fee schedule that separates government-mandated from company-set lines
- Renewal clause with a notice window you can actually track
- Annual and monthly billing priced side by side
- A price that survives a competing quote
Red flags in a proposal
- Seat-price-only quotes that wave at 'plus taxes and fees'
- Full-term auto-renewal behind a 30-day notice window
- ETFs equal to every remaining month at full price
- 'Free' hardware repayable in the fine print
- Sign-today pressure before your other quotes arrive
What South Carolina adds to a phone bill
| Question | South Carolina answer |
|---|---|
| State 911 surcharge (business lines) | $0.65/month per line for wireless AND VoIP (identical rate); landline ongoing fee tiered $0.50-$1.00/line/month by carrier access-line count (plus a one-time-higher startup tier $0.75-$1.50) (per mobile identification number (wireless/VoIP); per local exchange access facility, tiered by carrier size (landline)) - SC DOR fee schedule lists CMRS/VoIP 911 charge = $0.65/mo (same rate for both) plus a $0.03 Dual Party Relay charge; landline max rates set by SC Revenue & Fiscal. |
| How the state treats VoIP providers | Deregulated for rates/entry -- 2016 S.B. 277 removed SC Public Service Commission oversight of IP-enabled/VoIP service rates and market entry - VoIP providers register with the Office of Regulatory Staff (ORS), not the PSC, for state telecom purposes, and must file numbering requests with the PSC's Chief Clerk. |
South Carolina's landline 911 fee isn't one statewide number -- it's set by a 3-tier schedule based on how many access lines the local carrier serves (bigger carrier = lower per-line rate, $1.00 down to $0.50/mo), while wireless and VoIP both pay a flat $0.65/mo no matter the carrier's size.

Fee schedules, 911 surcharges and telecom rules are set by federal and state authorities and by individual contracts, and they change - verify current rates with your state and the full fee schedule with any provider before signing.
Why only these two paths
The most expensive line in a phone contract is the one that renews itself: miss the written-notice window - commonly 30-90 days before term end - and many contracts renew for another full term, early-termination fee and all.
Hard bar, verifiable by anyone: free to the buyer, and structurally multi-vendor - one request produces several competing quotes, which is the check against over-quoting that no single provider relationship provides. Marketplaces that charge buyers or route to a single seller are not listed - and any listed path that drops below the bar gets removed.
| Path | What it is | Why it made the bar |
|---|---|---|
| BuyerZone | B2B quote marketplace (business phone systems and other business categories) | One form, multiple vetted sellers respond with competing quotes - free to buyers |
| 360Connect | B2B quote marketplace with local service-area matching | Matches up to five suppliers per request, 100% free to buyers |
Before signing any phone contract
- The full monthly total per user with all taxes and fees estimated - not the bare seat price
- The contract term, the renewal clause, and the written-notice window - in days, in writing
- Which bill lines are government-mandated and which are the provider's own recovery fees
- Annual versus monthly billing priced side by side - the gap commonly runs 20-50%
- Any analog lines in the building - elevator, fire alarm, fax - and their migration plan

Common questions
What hardware do I need for a VoIP system?
Desk phones run about $55-$90 entry-level, $120-$280 mid-range, and $400-$990+ for conference-room units in current reseller pricing. If your building lacks wired Ethernet at each desk, budget roughly $125-$400 per cabling drop installed, plus a PoE switch (from about $70-$150 for a basic 8-port unit) to power the phones. 'No upfront cost' plans price the software - the building's wiring is your line item.
Are the '99.999% uptime' claims real?
They are contractual targets, not audited history. The math: 99.999% allows 5.26 minutes of downtime a year, while 99.9% allows 8.76 hours - and independent status-tracking services document real incidents at every major provider. The practical risk is usually closer to home anyway: a local internet or power outage takes cloud phones down regardless of the provider's data centers, unless you configure cellular failover or call-forwarding in advance.
What is a typical early termination fee?
The most common structure is every remaining month multiplied by the monthly fee - a 24-month contract at $150 a month cancelled after 6 months can mean a $2,700 exit bill - though some providers use flat fees around $295-$995 instead. Providers may also claw back 'free' hardware or installation credits. No regulator caps these terms for business lines; the contract is the whole ballgame.
Can my phone provider stop me from keeping my number?
No. FCC rules bar any provider - including VoIP providers - from using a contract to block you from porting your number to another provider, and require simple ports, including to and from VoIP, to complete within one business day. An early-termination fee may still apply under your contract, but the number itself cannot be held hostage.
What is SIP trunking and when does it make sense?
SIP trunking replaces the copper lines feeding a phone system you already own - priced per concurrent call channel, commonly $15-$30 per channel monthly for unlimited plans - rather than per user. The decision line is your existing hardware: if you own a PBX worth keeping, SIP trunking preserves that investment; if you are ready to retire it, per-user cloud seats usually price out simpler and include the features separately billed elsewhere.
What happens to my fax, elevator and fire alarm lines?
They are the catch in the copper shutdown: elevator emergency phones must meet ASME A17.1 and fire alarm dialers must meet NFPA 72, and standard VoIP satisfies neither - an office can migrate every desk phone and still fail inspection. The current fix is a certified cellular POTS-replacement adapter at roughly $30-$60 per line monthly, versus legacy copper holdout pricing that has climbed to $150-$500+ per line in many areas.
