FaxTo vs eFax: which fax service fits occasional faxing?
eFax is built for offices that fax steadily every month: you buy a page allowance and use it. FaxTo is built for people who fax a few times a year — you buy credits, one credit covers one page, unused credits do not expire, and a failed transmission costs nothing. If you fax under roughly 20 pages a month, a monthly allowance is money you do not use.
Side by side
| What you are comparing | FaxTo | eFax |
|---|---|---|
| Pricing model — FaxTo leads on this | Credits — 1 credit = 1 page. Monthly plans include credits; one-off packs never expire. | Monthly subscription with a page allowance. Unused pages do not roll over. |
| Published list price — No meaningful difference | Not published yet — the app is pre-release | Not shown as a fixed figure on the pricing page — it is configured by page, user and number count. |
| Pages on the entry plan — No meaningful difference | As many as you hold credits for; buy more at any time. | 200 pages/month to the US and Canada, then $0.10 per extra page. |
| How a page is counted — FaxTo leads on this | One page is one credit, whatever is on it. | Billed against transmission time, so eFax states that graphic-intensive pages may count as more than one page. |
| A fax that fails to send — FaxTo leads on this | No credit is charged. The app retries a busy line automatically. | Counted against your monthly allowance under the standard page-counting rules. |
| Receiving faxes — The other app leads on this | Dedicated US or Canada number on the Pro plan; receives from anywhere in the world. | Included on every plan — one fax number, additional lines $5/month. |
| International sending — FaxTo leads on this | 40+ countries on every plan. | 51 countries, but only on the Business plan; the Personal plan is US and Canada. |
| Track record — The other app leads on this | New product, not yet on the app stores. | Running since 1999, with the compliance paperwork and enterprise support that implies. |

Choosing between FaxTo and eFax
FaxTo suits you if…
- You fax occasionally — a tax filing, a dispute letter, a cancellation — and a monthly page allowance would mostly go unused.
- You want the cost of a fax to be predictable: one page, one credit, no surcharge for a scanned page full of stamps and signatures.
- You want to scan, merge, add a cover page and send from one app on your phone.
- You would rather not pay for a fax that never arrived.
eFax suits you if…
- You fax steadily every month and a 200- or 500-page allowance genuinely gets used.
- You need a vendor with 25 years of operating history, enterprise contracts and formal compliance paperwork.
- You need multiple users on one account, or several fax numbers.
- You need it today — FaxTo is not on the app stores yet.
The real difference: an allowance you rent vs. credits you own
eFax sells a monthly page allowance. That is the right shape for a clinic or a law office that faxes most working days — the per-page cost drops as you use more of what you already paid for. It is the wrong shape for the person who faxes a withdrawal letter to a retailer twice a year, because an unused allowance resets to zero at the end of every month and the subscription bills again.
FaxTo sells credits. One credit sends one page. Credits that come with a monthly plan renew each month; credits bought as a one-off pack have no expiry date at all. Nothing resets against you.
What counts as "a page"
This is the detail most comparisons skip, and it is the one that changes the bill. eFax measures transmission time rather than sheets of paper, and says so plainly: a graphic-intensive page may be charged as more than one page. A scanned document — a signed petition, a stamped invoice, a photographed form — is exactly the kind of page that takes longer to transmit. So the pages most likely to be faxed to an institution are the pages most likely to cost extra.
FaxTo counts sheets. A page is one credit whether it is a paragraph of text or a dense scan, and the app shows the credit cost of the document before you send it.
Who pays for a fax that does not arrive
Institutional fax lines are busy lines. When a transmission fails on FaxTo, no credit is deducted and the app retries automatically before reporting the failure. Under a page-allowance model, transmitted pages are counted whether or not the exchange completed to your satisfaction — worth confirming against your own plan before you rely on it.
Where eFax is genuinely the better choice
eFax has been operating since 1999. If you are procuring for an organisation, that history comes with things a new app cannot offer: negotiated contracts, multi-user administration, an account manager, and a compliance record a legal team can review. eFax also includes receiving on every plan, where FaxTo puts a dedicated number behind the Pro tier. And eFax is available right now, which FaxTo is not.
