Experience OK but not worth the price. The cost of the service seems too high.

Number wouldn't port. We couldn't port our existing fax number. We liked the software, but it wasn't worth the amount of work that would go into changing the fax number everywhere for a doctor's office, nor did we want to pay for two services so that we could forward our number.

Not as effective receiving faxes as a traditional machine. We are unable to receive all faxes. 5% of income faxes are never received and we have to direct people to fax to our back office fax line Update: I have tried multiple times to have this issue resolved through support. I am told the person sending the fax has a problem with their phone line. but yet they can fax to my back office fax no problem. Tell me how that makes sense?

I have been a customer since April… I have been a customer since April 2017. Any time there is a customer service issue, it's concerning. For example, I have emailed and called 3 times this week. I just emailed again today. I need my fax to work. My billing is up to date, yet there are errors preventing me from changing my password. Customer service has been awful.

Excellent service. Reliable. Secure. I am not a heavy user of secure fax, however I am a critical user. I chose Sfax because it was the only one at the time which offered HIPAA security and also didn't require a big buy-in or monthly fee for occasional users. The security is still there but recent changes have made it less practical for occasional users like myself. If that does not apply because you are a business user, I can recommend Sfax without reservations.
