Lesley Spencer Pyle, who founded Homebased Working Moms in 1995, says they research companies that place ads on the site with the Better Business Bureau, "but it's not foolproof." So good judgment reins. She does suggest if after you do your research and decide to pay money up front for materials or business kits (which I'm not convinced is ever a good idea), use a credit card so you can dispute the charges with the credit card company if a refund is necessary.
Use reputable web sites to find and vet work-at-home opportunities. There are work-from-home jobs that will provide the flexibility and pay many are seeking, but you've got to do some research to make sure they are legitimate. To check out a company, start with the Better Business Bureau. If you've got a sneaky feeling that a work-from-home job ad is really a scam, you may find it at scambusters.org, which gathers info on all kinds of online and offline scams. And you'll have a better shot of finding legit opportunities on sites that have women's best interests in mind and vet ads on their sites. Women For Hire is one, and you'll find some good advice on how to avoid scams on the site, too. Homebased Working Moms is another site that has been focused for nearly a decade on helping women find rewarding, well-paying work-at-home opportunities.
