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 is bringing a free, self-serve HIPAA BAA to every paid plan from $19/month (coming soon, signed in Settings), provides $2.99/fax pay-as-you-go, charges no overages at all, 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 Solo is $19/month (300 pages), Practice $29/month (800 pages), and Multi-site $59/month (unlimited pages, API) — none charge overage, and a free HIPAA BAA is coming to all three (signed in Settings). Verify current Fax.Plus pricing at fax.plus (as of September 21, 2026).
usfax.com is bringing a free, self-serve HIPAA BAA to every paid plan, from $19/month — you will sign it yourself in Settings → HIPAA BAA — with TLS 1.2 or higher, 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.
If you need fax numbers outside the US, Fax.Plus is the stronger choice — it offers international numbers across many countries, while usfax.com is purpose-built for US businesses with US numbers. Choose Fax.Plus for global coverage; choose usfax.com for US-focused pricing, support, and HIPAA.
