When launching a business, startup costs are the expenses that must be paid before the operation can begin. This includes any short-term and long-term investments required to get the business up and running. Startup costs may include office supplies, legal fees, wages for employees, website design, marketing material, equipment leasing fees, or insurance premiums. Often, these costs must be paid out of pocket, but businesses may also be able to seek outside funding from investors or other sources. By taking the time to properly plan for startup costs, entrepreneurs can ensure their venture is set up for success in the long run.
