eFax vs SRFax

TL;DR

eFax is the most universally recognized online fax brand with extensive enterprise features. SRFax is a more affordable HIPAA-compliant alternative that includes the BAA on every plan tier including the entry-level $5.95/month plan. For most ABA agencies — particularly solo BCBAs and small clinics — SRFax is the right choice. eFax wins only when brand recognition with specific counterparties is essential.

When to pick eFax

Pick eFax when brand recognition with payers, large vendors, or contractually-significant counterparties matters. Some payer-portal verifications, large-vendor onboarding processes, and partnership contracts specifically expect an eFax number, which can occasionally cause friction with less-known providers.

eFax's enterprise feature set — bulk send, API access, dedicated number portability — is also more developed than SRFax's. Mid-to-large agencies with complex fax operations sometimes find eFax's depth worth the price premium.

When to pick SRFax

Pick SRFax when cost-effectiveness and HIPAA-without-tier-gating matter. SRFax includes the BAA on every plan starting at $5.95/month, where eFax requires Corporate or specific HIPAA-tier products at much higher monthly cost. For solo BCBAs and small clinics, that single decision saves real money over a year.

SRFax is also genuinely reliable. Operators consistently report that faxes go through, inbound documents arrive promptly, and the platform stays up. For prior-authorization workflows where a missed fax can delay service by a week, that reliability is more important than brand recognition.

Where they overlap

Both are HIPAA-eligible online fax services. Both cover inbound and outbound fax via web, email, and API. Both have been operating in the U.S. healthcare market for years with established compliance posture.

Pricing

SRFax Basic starts at $5.95/month with HIPAA BAA included. eFax Plus starts around $19.95/month, with HIPAA-eligible Corporate or HIPAA-tier products meaningfully higher. For ABA agencies, the SRFax pricing advantage is real: comparable functionality at a fraction of the cost.

How GoodABA fits alongside either

Fax infrastructure is outside GoodABA's scope. Whether you pick SRFax or eFax, GoodABA covers the rest of the agency stack — branded family portal, intake forms, e-signed consents, client record, and communications log. Fax remains a payer-required workflow for most ABA agencies regardless of how modern the rest of the stack becomes.
