Every startup business needs certain basic tools of the trade. Don’t skimp on the tools you really need. But if money isn’t abundant right now, don’t buy anything that won’t significantly enhance your productivity or profitability.

For most entrepreneurs the essential tools include:

• Computer, monitor and printer

• Software

• Surge protector or uninterruptible power supply (UPS)

• Telephone and a voice-mail system or answering machine

• Internet connection

• Fax machine

• Desk, chair, lighting, bookshelves and a file cabinet or two

• Office supplies

When shopping for big-ticket items such as computers, buy enough speed and storage capacity to do your work well. But don’t max out with a top-of-the-line machine if you’re using it just to do word-processing and spreadsheets. If your budget is extremely tight, buy used or rebuilt equipment.

The amount of time you spend online should determine what Internet connection speed you’re willing to pay for—a fast broadband service (DSL or cable modem) or a less expensive dialup account.

If you spend time online through a dialup connection or receive faxes frequently, you’ll need a second phone line. If you rarely receive faxes and don’t need a second line for Internet service, consider services such as eFax, which deliver incoming faxes via e-mail. (You’ll need fax software on your computer to send faxes to others.)

Make sure your desk and chair are comfortable and ergonomically correct. A computer desk, for example, is shorter than a traditional desk. Computer desks give you a more body-friendly position for keyboarding and looking at the monitor. Never buy a bargain-basement chair that lacks back support or height adjustment.
