PayPerFax Internet Faxing Service lets you send and receive faxes from your computer on a pay per page basis. It still gives the same benefits as other online faxing services, but with no monthly fees. Pages are charged 75 cents for the first page and 40 cents for each succeeding page. This is the perfect choice for those who don’t really have high volume requirements or have sporadic faxing needs. PayPerFax uses a web based fax system that lets you upload your file and pay online. The only downside to PayPerFax is that you do not get a permanent number for incoming fax. You can reserve a number for 30 minutes and pay for anything longer than that.
PayPerFax is recommended for casual fax users. This allows you to send faxes online without a fax machine, without any commitments.
