Online fax, on the record.
Almost every 'best online fax' list is written by a fax company ranking itself first. We're independent — so we can tell you which services actually sign a BAA, at which tier, and what a page really costs.
Fax Ledger compares online fax services on published pricing — no hands-on testing.

The Online-Fax Plan Picker
Which fax plan fits your volume?
Set your monthly page volume and whether you need HIPAA coverage. We map it to a published-pricing plan profile and an illustrative annual cost — a starting estimate from published rates, not a tested result.
Cover sheet
Combined sending and receiving. Track a typical 30-day period if you can.
Do you fax protected health information (PHI)?
If your office is a Covered Entity and faxes patient information, a signed BAA is required — not optional.
Where the rates point
Standard flat plan
Moderate volume · no BAA needed
Illustrative annual cost: about $155 (within a 500-page flat plan at ~$12.95/mo)
For 300 pages/month, match the plan to the page allowance, not just the monthly headline. A 500-page flat plan covers most small offices outright; past that, published per-page overage adds up fast, so a higher tier is usually cheaper than overage on a small plan. Add ~20% buffer for busy months and check whether a toll-free number costs extra.
Read the matching plan guides
Illustrative only — figures come from published vendor pricing and per-page overage rates, not a contract or a test. Toll-free numbers, porting fees, and international rates change the real total; verify current pricing on the vendor's page before you subscribe.
