MetroFax vs Documo (2026): which should you pick?

Pick MetroFax if

• Fits if you send and receive a few hundred pages a month, in uneven amounts
• Works for small offices where up to five people share one fax number by email

Look elsewhere if

• Skip it if you want time to try it, as the trial lasts 3 days
• Not for you if you need an API, a signed BAA or a desktop app, as none is on record
• Watch out: email faxing fails unless your sending address has SPF records set up
• Watch out: overage comes from a prepaid balance that tops up in $10 steps, and faxes outside the US and Canada cost extra
• Tight if you need more numbers, as extras, up to 10, are added by a specialist after sign-up, not online

Pick Documo if

• Fits if you run a clinic or practice and need a signed BAA on even the smallest plan
• Works for healthcare software teams building fax into their own product through an API

Look elsewhere if

• Pricey if you're one person, as Solo is $25 a month billed yearly for 300 pages, with 15 cents for each extra page
• Skip it if you want to fax from a phone or desktop app, as none is listed
• Watch out: faxes are kept for 1 year on Solo, Business and Enterprise
• Not for you if you want the API on Solo, as it starts on Business at $80 a month billed yearly
• Watch out: the AI add-on is priced per document by sales, and the FAQ gives Enterprise as $250 a month, not the $240 shown

MetroFax

• Pages over the plan come from a prepaid balance that tops up in $10 steps when it drops below $2.
