Fax.Plus vs Phaxio (2026): which should you pick?

Pick Fax.Plus if

• Fits if you fax a few hundred pages a month from email or your phone
• Works for small teams that want shared fax numbers under one admin

Look elsewhere if

• Skip it if you want to receive faxes free, as the free account sends 10 pages in total and has no number
• Pricey if you need a signed HIPAA BAA, the API or Zapier: all three are on Enterprise, from $79.99 a month billed yearly
• Tight if you send long documents on Basic, which caps a fax at 60 pages and charges 10 cents a page over 200
• Watch out: porting a US or Canadian number and toll-free numbers start on Premium at $13.99 a month billed yearly
• Watch out: numbers beyond the two on Business are $4.99 a month each, and picking a specific number is $19.99 once

Pick Phaxio if

• Fits if you're a developer who needs to send faxes from your own software
• Works for low-volume senders who don't want a monthly plan

Look elsewhere if

• Not for you if you don't write code, because the main way in is the API
• Skip it if you want a free trial, as there isn't one
• Watch out: the API allows one request per second per account unless Phaxio raises it
• Pricey if you send a lot: volume rates only start at 50,000 pages a month

Fax.Plus

Fax numbers and porting

Pick a local, toll-free or international number from 48 countries, or port your existing number in. Porting a US or Canadian number needs Premium or higher.

Team admin console

From Business up, manage members, roles, number access and page limits in one place. Enterprise adds SSO, SCIM and per-user page quotas.

Fax API and AI assistant access

A programmable fax API is part of Enterprise, and an MCP connection lets ChatGPT, Claude and other assistants send faxes for you.

Phaxio

JSON fax API

Send a fax with one call that takes a number and a file, or post a URL or a string of HTML to be rendered and sent.

Batching and retries

Batching and collision avoidance keep faxes from hitting a busy number, and retries for busy lines and other errors are configurable.

Callbacks and metadata

Failed callbacks are retried for three days, and each outgoing fax can carry metadata such as an order number or patient record number.

Numbers for receiving

Receive faxes on a US or Canadian number at $2 a month, or use the shared Phaxio number with a PhaxCode on the document.

Dashboard

A web console lists faxes, provisions numbers and lets you trigger a callback by hand.
