Last updated · Written for a new business deciding whether to buy fax hardware at all.
No. You do not need a fax machine to send or receive a fax, and for a new business buying one is usually a mistake. An online fax service places and answers the fax call for you: you send from a browser and receive incoming faxes as PDFs by email. A machine is worth having only if you handle high volumes of paper that never become files, or work somewhere with no dependable internet.
What does a fax machine really cost?
The purchase price is the least of it. The recurring items are what catch a new business out.
- A dedicated telephone line. A fax machine cannot share a line that people also talk on, so it needs its own — a monthly charge from a phone company, indefinitely, whether you fax once a week or never.
- Consumables. Toner or thermal ribbon, paper, and a machine that jams when neither has been checked.
- Presence. An incoming fax lands on paper in a room. If nobody is in that room, the document sits there — visible to anyone who is.
- No record you can search. A machine gives you a printed transmission report. It does not give you a searchable archive of what you sent and when, which is precisely what you want when an agency asks.
What replaces a fax machine?
An online fax service does the same job with software. Your document is converted to the page images a fax machine expects, the service dials the recipient and transmits, and it reports back what happened. Incoming faxes run the other way: the service answers your number and emails you a PDF. The reader never touches a phone line.
| Fax machine + phone line | Online fax service | |
|---|---|---|
| Hardware | Machine, paper, toner | None — a browser |
| Line | A dedicated analog line, billed monthly | No line at all |
| Cost to start | Machine plus an ongoing line charge | $2.99 for one fax, or $19/mo with a number and 300 pages |
| Where an incoming fax lands | On paper, in a shared room | As a PDF in your inbox and dashboard |
| Record of what you sent | A printed slip | A searchable history with delivery confirmations |
| Works away from the office | No | Yes — anywhere with a browser |
| Reliability on a modern phone line | Depends on the carrier carrying fax correctly | Not your problem; the service handles the telephone leg |
Why a machine on a modern phone line is a gamble
Fax was designed for an analog telephone circuit. Modern phone service is usually digital, and compressing the audio can corrupt the tones a fax depends on — the transmission dies part-way through a page, or the pages arrive scrambled. This is not a theoretical concern: the Oregon Health Authority tells new Medicaid providers in writing that a fax system without T.38 support “may fail to send,” and advises phoning to confirm receipt 48 hours later. If you are buying a machine today, you are buying that problem. The detail is on fax over VoIP.
Is a machine more secure?
It feels more secure and generally is not. A fax machine prints a document face-up in a room that other people walk through, and the telephone leg of a fax call is unencrypted whichever end you use. An online fax service at least keeps the document encrypted in transit and at rest and behind a login — on usfax.com documents are stored in the United States, and the service is HIPAA-ready, with a free self-serve Business Associate Agreement coming to every paid plan. Until an account holder has signed a BAA, the account is not covered by one and should not carry protected health information.
When does a machine still make sense?
Two cases, and they are narrow:
- Paper in, paper out, at volume. A records department that receives hundreds of pages a day and physically files them is doing something a PDF workflow would only complicate.
- No dependable internet. A site where connectivity genuinely cannot be relied on, and a copper line can.
A brand-new, one-person business is almost never either of these. You have a form to get to an agency and possibly a reply coming back, and that is a browser and a number.
So what do I actually need?
- To send once: nothing but the file and the recipient’s number. $2.99 covers up to 10 pages. Start at how to send a fax.
- To be faxed back: a fax number of your own. Solo is $19 a month ($15 billed annually) with one US number and 300 pages, and a 7-day free trial with no card. See how to get a fax number.
