There’s nothing predictable in this world, especially in business. We couldn’t expect that our income gets higher as time goes by although we have planned the production and marketing strategy well. There are too many external factors that cannot be predicted, so it’s very important to buy insurance for your company.
Your company size shouldn’t protect you to buy public liability insurance. Small companies often think that buying insurances equals to spending extra money because they don’t understand the bad risks that will happen if they don’t have insurance. What will you do if your area is being flooded and you store all of your goods in the first floor? I bet that you don’t have budget to buy new equipments and goods.
In contrast, big companies realize the benefits of buying insurance to protect their products, employees, equipments, etc. Buying health and life insurance for their employees has become a must so they don’t have to pay extra and unpredictable amount of money when there’s employee suffers cancer/stroke/etc.
If you already bought insurance for your business, you can focus on expanding your products and networks without worrying about natural disasters continuously. In addition, your mind becomes more relax and your life becomes healthier too.
To end this article, let me ask you a question: Do you buy life insurance for you and your family? I bet that buy the life and health insurances since you are very concern about paying high medical bills if one of you get sick. You can also get the best medical treatment without worrying paying the hospital bills 
It’s the same with your business!
