Two capable online fax services — but Fax.Plus locks HIPAA to its priciest tier and meters every plan per page. Here's how they compare for US business in 2026.
7 day free trial.
Fax.Plus is capable and feature-rich — a send-only free tier, broad international coverage, an API, and an interface many users like. The trade-offs for a US business: its HIPAA BAA is locked to the Enterprise tier (from $79.99/month) and every plan meters per page. usfax.com offers $2.99/fax pay-as-you-go, lower overages, US-based support, and a self-serve HIPAA BAA at $49/month — making it a strong Fax.Plus alternative for US business. If you need international numbers, Fax.Plus is worth considering.

For US businesses, yes. Fax.Plus is genuinely feature-rich — a free send-only tier, broad international coverage, an API, and a polished app. But its HIPAA BAA is locked to the Enterprise tier (from $79.99/month) and every tier meters per page. usfax.com includes a self-serve HIPAA BAA on its $49/month Business plan, offers $2.99/fax pay-as-you-go, charges lower overages, and provides US-based support — making it a focused Fax.Plus alternative for US business.
Fax.Plus Free gives you 10 pages total, send-only, with no fax number and $0.20/page after that — great for a one-off. If you fax regularly, usfax.com's $2.99/fax pay-as-you-go (up to 10 pages) is simpler than a metered plan, and its published monthly plans include a dedicated US number, receiving, and US-based support.
Fax.Plus Basic is $6.99/month (200 pages, $0.10/page overage), Premium $13.99/month (500 pages, $0.07/page), Business $27.99/month (1,000 pages, $0.05/page), and Enterprise from $79.99/month (HIPAA + BAA, API, SSO). usfax.com Individual is $12/month (200 pages, $0.05/page), Professional $24/month (500 pages, $0.04/page), and Business $49/month (unlimited pages, HIPAA BAA, API).

usfax.com includes a self-serve HIPAA BAA on the Business plan at $49/month, signed online in minutes, with TLS 1.3, AES-256, and audit trails. Fax.Plus only offers HIPAA and a BAA on its Enterprise tier, which starts at $79.99/month. For a small or mid-size US practice that just needs a signed BAA, usfax.com is the lower-cost path to compliance.
