Business start-up costs refer to the expenses associated with launching a new enterprise. These include financial expenses such as rent, office equipment and supplies, legal fees, advertising, and consultant services. Start-up costs also include certain non-financial costs that you may encounter when starting a business, such as obtaining necessary permits or licenses. It’s important to budget for these costs in advance, so that you have the resources to cover them when they come up. Failing to do so could put you at risk of not being able to launch your business successfully.
