     After years of trying to balance work with motherhood, Karl Smith left her corporate (公司的) job behind

to start her own business.

     It's been over a decade since this mom entrepreneur (企业家) began making cakes out of her family's

kitchen. In that time, she has managed to grow Magical Moments & Elite Party Rentals into a well-developed

wedding planning and rental operation. Statistics show that these kinds of mommy-owned businesses are on

the rise. Many women say they can't find work that allows them to balance their responsibilities at home.

     Indeed, according to a national study conducted by Ipsos-Reid on behalf of Microsoft Canada, fifty-four

percent of female small business owners agree that being able to work at home to raise their family was a key

reason to leave the corporate world behind.

     "Being a mom entrepreneur means trading a typical 9-to-5 work week in for a more irregular routine," says

Gemma Moore, a busy mother of two who owns and operates MG Moore Designs, a design company

specializing in website, photography and print media. "Finding a business that you can build in the evenings will

allow you to spend time with your children during the day and continue your business after they go to school."

     Ninety-two percent of female small business owners say that mobile equipment and computer software can

help a mom entrepreneur make her own hours and work whenever she is most productive. In fact, ninety-five

percent agree that small business owners need to be more technology-savvy than ever before. The more

technology they master, the more successfully they will run their businesses.

     "Balance is a key aspect for most entrepreneurs, but this is especially true for women," says Ruth Bastedo,

President, Women Entrepreneurs of Canada (WEC). "Entrepreneurs recognize that today's technology can help

them to find work/life balance while still providing them with the tools and materials they need to grow their

businesses more effectively.
