Ooma Office Pricing (2026): $19.95–$29.95/User, Billed Monthly

On its cheapest plan that covers ten seats, Ooma Office lists $19.95 per seat per month on monthly billing. For ten seats that is $200 a month, or $20.03 per seat once three years of billing and any setup fee are counted.

The published figure is the one we compute with; no separately labeled monthly-billing rate is published on the page we read.

What it costs as the business grows

Effective cost per seat per month over three years, by the number of seats you actually have. Where a plan has a minimum, the minimum is billed and the cost per seat you use rises. “n/a” means the plan is not available at that size. checked 2026-09-05
Plan	1 seat	3 seats	5 seats	10 seats	25 seats	50 seats
Essentials	$20.78	$20.23	$20.12	$20.03	$19.98	$19.97

How that is worked out

seats billed = max(seats you have, minimum seats the plan requires) plan per month = published seat price x seats billed three-year cost = plan per month x 36 + setup fee effective per seat = three-year cost / (36 x seats you have) monthly-billing gap = monthly-billing price / annual-billing price flat package = flat monthly price + (seats billed - users included) x additional-user price add-on plans = shown on the provider's page, never ranked (they are not a phone system on their own) calls not included = shown on the provider's page, never ranked (calls are billed per minute, or sold as separate call packages, on top of the seat price) plan at each size = the cheapest plan that covers that seat count; a plan with a user cap hands over to the next one

Nothing else is added. Taxes, regulatory recovery fees, USF and e911 charges are not added to any figure on this site. 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 a plan needs another subscription first (a Google Workspace or Microsoft Teams license), that subscription is not in the figure and the page says so. Handset purchases, number porting, international calling and overage are excluded. Every figure here is a floor. The full method is at Method.

Taxes and fees

Ooma Office says taxes and fees are added and vary by location, with a lookup rather than a figure. Where it says so. checked 2026-09-05

No figure on this page includes those charges, because this provider does not publish what they come to. In the United States they are real and recurring: government taxes and surcharges that vary by location, and in many cases a recovery or administrative fee that the provider sets itself. The invoice will be higher than any figure here.

Who owns it

Who owns this company is not stated on its own site, and we could not confirm it from a primary source. We have left it blank rather than repeat what other sites say.

Where this leaves you

If the three-year seat cost is what matters, Grasshopper works out at $5.50 on the same basis — compare the two.
Do not treat any of these as the invoice: Ooma Office says taxes and fees are added and vary by location, with a lookup rather than a figure — what providers do and do not say about fees.

Who this page is not for

This is not a review. We have not used Ooma Office, we hold no opinion on its call quality or its support, and nothing here is a recommendation. It answers one question: what the published price turns into per seat over three years.
