Budget for more: taxes and regulatory fees where applicable, desk phones, number porting, usage and optional add-ons are outside these totals. See the extra-cost guide.

Published base prices for the five lowest three-year effective seat costs we can compute. Plans differ in features and billing terms; annual billing may require a year-long commitment or payment up front.

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

Each provider page shows the official source and date checked. The figures above are base costs, not quotes or complete invoices.

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.

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 widest gaps between annual and monthly

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.
