If you are leaving eFax, first decide whether you need a single outbound send, a number to receive replies, or a recurring office workflow. These are different purchases. Comparing a one-time send price with a monthly plan’s per-page price can hide the total cost.
| Your need | What to compare |
|---|---|
| Send one document | Checkout total, page limit, supported destination, and final delivery reporting |
| Receive a reply | Number term, renewal, inbound delivery method, and access to received files |
| Replace a recurring plan | Monthly and annual totals, included pages, overage, users, storage, and cancellation terms |
| Keep an existing fax number | Choose a provider that confirms porting before canceling the old service; Onetime Fax does not currently port numbers |
Onetime Fax offers a $5 send covering up to 100 pages, then $0.05 for each additional page. Sending does not require a subscription or a sending account. Enter the recipient’s fax number and your email, upload the document, review the total, and pay. Check the status page and delivery email for the final result; payment by itself does not prove delivery. International sending uses the same starting price for supported destinations. The form validates number format, not provider coverage; email help@onetimefax.com with the destination country if you need to check before paying. See pricing for the current terms.
If you need someone to fax a document back, a virtual fax number is a separate purchase: $10 one-time for 30 days or $10/month with automatic renewal. Do not buy a receive number just to send one document.
Plan prices, included pages, trials, and features change. Instead of relying on an undated price list, open each provider’s current plan and terms before switching. Compare:
For a broader selection framework, see Compare Online Fax Services. For a short document and no ongoing number, you can start a one-time fax.
A pay-per-send service avoids starting a monthly plan. Onetime Fax charges $5 for up to 100 pages, then $0.05 per additional page.
No. You need the recipient's fax number and your email for updates. Get a separate receive number only if someone needs to fax you back.
No. Onetime Fax currently assigns a new available US number; it does not offer number porting or area-code selection. Keep your existing service active until you have arranged a transition.
Check your organization's requirements, the provider's controls, and any required business associate agreement before sending regulated health information.
