If you use a fax machine to send contracts or other documents to clients or customers, you may occasionally get stuck in the office waiting to send or receive a fax. This can be especially cumbersome if you work in an industry that requires lots of time on the road. Luckily, you don’t have to choose between leaving and waiting around for a fax. With the right app, you can send and receive faxes via your smartphone from almost anywhere. Hellofax lets you keep your existing fax number or create a new local number. When someone sends a fax to your number, the app converts the fax into a PDF that you can easily open and view on your phone. This app also lets you send faxes to clients. A similar service eFax allows you to send faxes using email or an app. You can send Word documents as well as documents from compatible HP and Epson printers. In addition to letting you send faxes from anywhere, eFax lets you easily send large documents that would be time consuming to send with traditional fax machines. With most fax apps, you add multiple numbers, connect multiple employees, and choose how faxes get delivered. In exchange for the service, these apps typically charge users a monthly subscription fee. The right smartphone apps improve communication between you, your clients, and your staff. In addition to faxing apps, you may also want to check out electronic signature programs that allow you to collect signatures on paperwork without printing or faxing anything.
