There's a growing wave of one-person businesses across the United States. As such, technology for solopreneurs is improving rapidly, moving far beyond just laptops and smartphones.

While many solopreneurs like the flexibility of working for themselves and plying their trade anywhere, anytime, they are often under a tremendous amount of pressure to be productive constantly. Here are five tools that can help solopreneurs work smarter.

1. Evernote

When it comes to organizing your work schedule, making to-do lists and taking notes on the go, Evernote is the gold standard. Used by millions, Evernote also supports sharing and collaboration across multiple devices and platforms, making it an extremely useful tool for today's solopreneur.

2. Mozy

If you lost your laptop or mobile device, it might be difficult for you to retrieve files and information that are critical to your company's success. This is where services like Mozy come in. You can use this solution for cloud-based backup storage. As an Inc. article explains, "If you want to stop being vulnerable, you need an off-site backup system, and an automatic cloud-based one is by far the easiest." Many solopreneurs also use Dropbox, which offers the same backup storage functionality.

3. Wave

When you do work for clients, they'll expect you to send them an invoice. While you can certainly create invoices manually, this can be a time-consuming process that's difficult to track. Wave offers an accessible, convenient answer. This free, downloadable software lets you prepare and send invoices to clients who can then pay you via a number of different options. You can integrate Wave with your bank account and even use the software to send payment reminders to your clients.

4. Shoeboxed

As a solopreneur, you want to be able to travel lightly, without being tied down by paperwork. Having the ability to scan and digitize essential paper documents — from legal contracts and business cards of potential customers to receipts for business expenses — can enhance your ability to be productive on the go. If you're on the hunt for this type of technology, Shoeboxed might be right for you. This software allows you to use your phone to cut down on paper clutter and organize your documents and data.

5. Skype

This popular app allows you to meet with clients anywhere in the world while working remotely. Known for its video conferencing capabilities, Skype is a great collaboration tool for any solopreneur. In fact, many solopreneurs, such as coaches and professional language instructors, actually deliver their services directly via Skype.

The amount of technology for solopreneurs only continues to proliferate. While the available tools may change, you can bet that solopreneurs will be adding more value to their clients as time and technology advance.
