Does a business phone plan include online fax, and what does it cost if not?

Summary

Which plans include fax, which sell it, and which say nothing

Scroll sideways on a phone.

The RingCentral row is the one to read twice. Its comparison table lists "Unlimited internet fax" as Not available on Core and Included on Advanced and the two AI Customer Engagement Bundles, so a team that signs up for the cheapest RingEX plan has no fax until it moves up. Ooma goes the other way: Virtual Fax is tied to a user's extension, comes with a dedicated fax number, and the fax page says it costs nothing extra on any Ooma Office plan. Zoom's 50 pages are printed without saying whether that is sent, received, or both, so it is reproduced here as "50 pages."

Nextiva's pricing table says only "Add on." Its separate vFAX page prices the product at $7.95 and $13.95 a month, describes the pages as one pool for inbound and outbound, says failed faxes are not counted, and charges $0.03 a page past the pool. The same page carries the title "Online Faxing Starting at $9.95", which does not match the figures in its own table and may be the monthly-billing price; both numbers are reported as printed.

100, 300 and 1,000 pages a month

Three of the six rows do not move with volume because the plan already covers fax; what they cost is the plan step, $5 a user a month at RingCentral and $8.50 at Zoom, both for every user on the account, not only the one who faxes. Zoom's US & CA Unlimited plan shows "not published" from 100 pages because the pricing page gives no rate for pages over the 50 included. The Nextiva vFAX and Fax.Plus rows pick the cheaper tier at each volume, so Nextiva's 1,000 pages is the $13.95 tier rather than the $7.95 tier plus 500 pages at $0.03.

If you fax a few pages a month

A business that sends ten pages a month has two cheap routes: Fax.Plus's free plan, which covers 10 pages in total rather than per month, or a phone plan where fax is already in the price. A five-person team on RingCentral Core would pay $5 times five each month for Advanced, which buys unlimited fax along with the rest of the Advanced feature list, so the comparison is between that and a $6.99 fax-only subscription. Which RingEX plan fits a small team now that RingCentral posts prices for only two? goes through what else the Advanced step includes.

A separate fax service also means a separate fax number. If the number on your letterhead has to stay, check that the service can port a fax number in before signing up; Fax.Plus lists number porting from its Premium tier. Keeping an analog fax machine on the line is a different question, covered in What do you give up when you swap a landline for a cloud phone system?.
