Which one is for you
Pick Fax.Plus if
- Fits if you fax a few hundred pages a month from email or your phone
- Works for small teams that want shared fax numbers under one admin
Look elsewhere if
- Skip it if you want to receive faxes free, as the free account sends 10 pages in total and has no number
- Pricey if you need a signed HIPAA BAA, the API or Zapier: all three are on Enterprise, from $79.99 a month billed yearly
- Tight if you send long documents on Basic, which caps a fax at 60 pages and charges 10 cents a page over 200
- Watch out: porting a US or Canadian number and toll-free numbers start on Premium at $13.99 a month billed yearly
- Watch out: numbers beyond the two on Business are $4.99 a month each, and picking a specific number is $19.99 once
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

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
