As with any business, starting a pet sitting home-based business does take some money. You will have three types of costs; marketing, transportation and insurance. Marketing, as mentioned above, can be started with $50 or less. Transportation includes gas, car insurance and car maintenance. Keep these costs separate from personal use. Keep track of mileage when going to and from a client as this is a tax deduction. Get a pre-paid cell phone just for the business. Purchase minutes as you need them and deduct this as a business expense. You can get away with spending $20 or $30 per month to start.
Many clients will ask if you are bonded, and insured. This is because they are leaving you alone with not only their pet, but also their property. Having insurance will cover the cost of anything breaking while you are in the house. Startup cost for insurance usually begins at $100 per year.
