LuzardoFax
Most online fax providers advertise a price that excludes the Business Associate Agreement. It sits on a higher tier, and a practice on the cheap plan is out of compliance from the first page it sends.
LuzardoFax includes the signed BAA on every paid plan, executed in-app during onboarding — not emailed as a PDF, not gated behind a sales call. Each signature is anchored to the Bitcoin blockchain through OpenTimestamps for independent verification.
Billing counts actual document pages, not 60-second transmission increments, so a dense scan or a slow receiving line cannot silently multiply your usage. Failed attempts cost nothing, and there is no automatic overage billing — at 110%, sending and receiving pause until you top up.
Encrypted at rest with LUKS2 (AES-256), TLS in transit, audit logs, two-factor authentication. Month-to-month; numbers port out with a documented exit kit. Bilingual English/Spanish. From $25/mo, 14-day free trial.
