\u201cThere\u2019s an app for that\u201d may be clich\u00e9 nowadays, but there\u2019s also some truth to it \u2014 if you need it for your business, chances are good there really is an app that covers that service. In fact, today's business owners can virtually run their entire business using these software and mobile applications.\nOrganization\nDocument Sharing\nServices like Dropbox, Google Drive and Box have become ubiquitous office features for businesses of all sizes, and with good reason: they allow you to share, edit and organize files and documents.

Asana, Basecamp and Trello are some of the most popular project management apps, and all go a step beyond lists, chats, and reminders that to-do lists offer.

The subscription versions include features like unlimited searchable message archives, group calls and priority support.\nVideoconferencing\nVideoconferencing is especially useful for organizations that work with offsite teams or contractors, because video conversations incorporate facial expressions, gestures and other body language that are critical to effective communication.

Square includes a card reader that plugs into your phone, allowing small businesses to accept credit cards from mobile devices. It\u2019s worth noting that Square takes 2.75 percent of each transaction.\nSecurity\nOnline backup\nOne of the worst feelings in the world might be \u201cI should have backed that up\u201d after experiencing a data loss. Services like iDrive and Carbonite let you back up multiple devices, securely access backed up files remotely, and will sync with connected devices. They back up your data continuously, so that in the event of theft or a crash, you can log into your account and restore your files and information.\nPassword manager\nIt\u2019s common knowledge that most of us use terribly insecure passwords. At the same time, no one can remember random strings of letters and numbers for the many accounts we need to access. That\u2019s where password managers like LastPass, 1Password and Dashlane come in. A password manager will generate and store your passwords across devices, which means you can have hard-to-break passwords on all your accounts.
