Write a thorough business plan. Whether you seek a loan from a bank, friends, family or investors, they will more than likely want a detailed plan of exactly what you will use the money for. Include details about your business concept, target market and niche, startup costs if applicable, three-year earnings projections, three-year spending analysis, information about competitors, marketing and public relations plans.
Apply for a business loan. Loans are available from banks and credit unions, but may be difficult to obtain for a startup, especially if you have no experience as an entrepreneur. Another option is a Small Business Administration loan program. The loans aren't given by the SBA, but are guaranteed through them, making a business loan easier to obtain.
Look for business grants. Business grants are not available from the federal government, contrary to what many believe, but they are offered through private groups, such as Business Owners Idea Cafe, nonprofit organizations and state agencies.
Borrow from friends and family. If you go this route, write an agreement that details the amount borrowed, how and when it is to be paid back, and what will be done in the event you fail to make timely payments.
Use money from your savings. Credit cards are also an option, provided you come up with a plan to pay them off as quickly as possible because there will be interest charges and other fees.
Lease your equipment and buy inventory on net terms -- you won't have to pay as much money upfront for the materials you need. You typically need established business credit or good personal credit to use these options.
Seek out partners or investors for your business. Investors are quite common for technology businesses and medical ventures, as well as entertainment companies. It is more likely you'll be able to get investors if you commit to investing a significant amount of your own assets into the venture. Doing so will signal that you believe in the potential of your business.
