Women are getting out there more than ever, and a lot of people make a point of supporting women-owned businesses. Not only that, but there are also incentives from the government, such as stimulus money for female business owners. Thus, getting certifications that yours is a local woman owned business is paramount. This video by Notary Nerds walks you through the steps of getting certified.
You can go about this in different ways, though all roads lead to the application. A lot of people have a third party complete the certification process, if only because they want to avoid the hassle of dealing with the federal government. However, if you either want to avoid the expenditure or are confident in your ability to manage the form, you can just as well do it yourself instead.
In order to qualify, you need to meet certain criteria applied by the U.S. Small Business Administration. It needs to fit the SBA's definition of a small business, be majority-owned by a woman, and have women involved in the management and operation of the business. After you've verified you meet these qualifications, you can then create an SBA account and apply for certification on SBA's website.
