Business Phone Costs per User (2026)

28 of 37 providers publish a price; 6 are quote-only. Where both rates are public, monthly billing costs 1.34 times the annual-billing price at the median.

On taxes and regulatory fees, 2 of the 37 providers state that the price already carries them on at least one plan, 0 publish what they come to, 14 say they are extra without an amount, and 21 say nothing. Where a provider says the price is all-inclusive or includes them, the page says so beside the figure; everywhere else the invoice will be higher than the figure.

10-seat US cost snapshot

The five lowest published totals among full US business phone systems we can compute at ten seats. This is a price order, not a quality ranking; plans are not feature-equivalent.

This table is wider than your screen. Drag it sideways to see every column.

Computed from provider-published prices for 10 seats. First-year total is 12 months plus any published setup fee. Taxes, hardware, porting, usage and add-ons are excluded. Each provider page links to the official source and shows the date checked.

Where to go from here

Provider list
Every provider we hold, in one table, with the published seat price and the monthly-billing column beside it. Read that column, not just the headline figure.
Seat cost calculator
Put your real seat count in and the list re-ranks. Minimum seat counts change which provider is cheapest below about five seats. It runs in your browser and you can copy a link to your result.
What the published price leaves out
Taxes, regulatory fees, handsets, porting and overage sit outside the figures on this site, except where a provider states that its price already includes them. Read this before you treat any of them as a budget.
The dataset
Every figure on this site as one file, in CSV and JSON, with each column defined and a licence that lets you reuse it. Free under CC BY 4.0.
The ones that will not tell you
What to do about the providers that answer the price question with a contact form, and what to ask them so the quote is comparable.
What changed
Every recorded price change, plan rename and correction, by month, with the old value and the new one. 128 entries across 27 providers in September 2026 (1 provider-side change, 127 corrections to our own data). There is an RSS feed.

Minimum seats

11 of the plans we hold bill a minimum number of seats. Below that number you pay for seats you do not use, which is why every table here shows the cost per seat you actually have rather than the price on the card.

What this is not

This is not a review site and it is not a quote service. Nothing here is rated, scored or recommended; there are no stars or badges, and we have not used any of these products. Every table is ordered by one computed number and the formula is published in full. No provider has paid to appear here, and we will never ask for your phone number.
