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.

Excellent except for one big flaw , can't send multiple files in one go See above see above see above

I was a customer from 2016 to 2024 I was a customer from 2016 to 2024. Billing issue when my bank placed Sfax on a list of potential threats. Before it was discovered, difficulties ensued. Unfortunately multiple emails to billing, tech support, and customer service yielded zero response. Left two voicemails. Never heard back. My fax did not work and I could not get through once locked out. It wasn’t about money or payment, it became a tale of avoidant customer service and neglect. I submitted a ticket to end services with my feedback attached, heard nothing. Received a canned email that my complaint was received and I would hear back in 48 hours. Week/s later it’s a second email that it’s cancelled. Truly one star as no amount of faxing interface would make this acceptable. I was never actually acknowledged.

It's OK It's OK. They don't have business plans that will benefit businesses. They charge lots of money for overage. I pay more in overage than plan. I provided them an opportunity to partner with my EHR company so that their software can be invoked from within EHR. They didn't care.

So far so good We have been using sFax for a number of months now. It's working well except we are having a bit of trouble porting existing numbers which seems to take up to 2 weeks.
