Side by side

The cheapest plan on each side that covers ten seats, United States pricing. Where a plan's user cap is passed at a larger size, the row names the plan the provider moves you to and prices that instead. Sources: CallHippo checked 2026-09-05 and Vonage Business Communications checked 2026-09-05.

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.

Where the answer changes

Size does not change the ranking here. Vonage Business Communications is cheaper per seat at every size where both have a plan.
The plan changes as the team grows. Vonage Business Communications moves to Mobile (1–4 lines) at 1 seat, then Mobile (20–99 lines) at 25 seats. The figures above already price the plan you would actually be on at each size, not the entry plan stretched past its cap.
If you will not sign for a year, Vonage Business Communications punishes it harder: 1.43 times the annual rate against 1.32.
Neither figure is the invoice — taxes and regulatory fees are added on top of both, and neither provider publishes what they come to.

What is not confirmed on either side

Figures on this page come from each provider's published pages only. These points were not stated there, so the comparison does not include them:

CallHippo (4 open items)

Taxes and regulatory fees: not stated in the provider's published documentation (checked 2026-09-05).

Fees disclosure: not stated in the provider's published documentation (checked 2026-09-05).

Ownership: not stated in the provider's published documentation (checked 2026-09-05).

Minimum seats: not stated; team-size selector starts at 1-4.

Vonage Business Communications (6 open items)

Taxes and regulatory fees: not stated in the provider's published documentation (checked 2026-09-05).

Free trial: not stated in the provider's published documentation (checked 2026-09-05).

Setup fee: not stated in the provider's published documentation (checked 2026-09-05).

Not confirmed: whether the 30% annual-contract discount is still applied at checkout: the annual "Buy now" links carry couponcode=30PERCENTOFF and the plan SKU, and the pricing page still shows the offer on 2026-09-05 despite "valid through January 31, 2026", but the cart (/promo/buy/) is blocked outside the US so the checkout total itself could not be read.

What changed on either side

24 recorded changes across the two providers: 0 on a provider's own page, 24 correcting a figure this site held. The most recent six:

2026-09-05 — Vonage Business Communications: correction to our data plan line-up Mobile, Premium, Advanced → Mobile (1–4 lines), Mobile (5–19 lines), Mobile (20–99 lines), Premium (1–4 lines), Premium (5–19 lines), Premium (20–99 lines), Advanced (1–4 lines), Advanced (5–19 lines), Advanced (20–99 lines). The pricing page prices each plan by employee-count band (1–4 / 5–19 / 20–99; 100+ is Contact sales). The earlier rows held only the 1–4 band figures, so each plan is now split into one row per band with min_seats/max_seats so the seat-count pages pick the right band.
