Cost and volume

Page price is only half the math.

Documo Solo's $25 annual-billing monthly equivalent equals five separate Just One Fax sends, but the included number, 300-page pool, BAA, and account are the real reasons to subscribe. It is not an apples-to-apples one-fax price.

Just One Fax prices each destination as a separate $5 transaction. One page and 100 final pages cost the same, but a second recipient or a later fax costs another $5. It does not preserve an unused monthly allowance or provide a fax number between sends.

1 send$5

2 sends$10

5 sends$25

Choose by workflow

Who each service is actually for.

Choose Documo when

A healthcare practice, regulated business, or product team that needs a BAA, inbound fax, administration, or APIs.

Your organization needs a BAA and healthcare-oriented controls
You need a receiving number and monthly 300-page pool
You may need users, APIs, SSO, or document automation

Choose Just One Fax when

The requirement is one prepared outbound U.S. fax, not a fax account.

You are an individual with one non-regulated U.S. outbound fax
You do not need procurement, account administration, or integration
You want to pay $5 once instead of entering an annual business plan

What Documo changes

The added capability has a tradeoff.

Distinguishing strengths

Published HIPAA claims and BAA availability across plans
Inbound number, retained cloud fax workflow, and user administration
Business tiers add users, numbers, APIs, SSO, and document automation options

Limits to inspect

The $25 entry price is a monthly equivalent billed annually
Product depth and account administration exceed what an occasional sender needs
Public plan pricing has separate overage and add-on charges

Hard boundaries

Account, inbound, geography, and compliance.

These distinctions rule out more options than a small price difference does.

Account: Just One Fax: no login or dashboard. Documo: Required.
Inbound: Just One Fax: no receiving number. Documo: Included through one fax number on Solo.
International: Just One Fax: U.S. destinations only. Documo: The public pricing page does not define a simple consumer country list; confirm required destinations with Documo during signup or sales review.
Compliance: Just One Fax: no HIPAA claim or BAA. Documo: Documo states HIPAA compliance is included on every plan and that it signs a BAA for healthcare accounts at no additional charge.

Provider compliance statements are not a substitute for your own legal, security, procurement, and configuration review. Confirm the exact plan and obtain any required agreement before transmitting regulated information.
