Dropshipping is a great inventory strategy for any size of business. You can use dropshipping to capitalize on a trending product like pet beds or to expand into new categories in a single click while running a multi-million dollar enterprise.
Your business objectives will determine how you should prepare to start dropshipping. If your primary goal is to explore entrepreneurship and financial success is a secondary goal, then you might be able to get started with less preparation. However, if your primary goal is to grow a business that eventually becomes your full-time occupation, then you will want to make sure you're setting up the business for long-term success.
