CapEx, short for capital expenditure, is the money your business spends on physical assets which will be used long-term in core operations – for example, a card machine or a point of sale system like POS Pro. You can find your CapEx in your cash flow statement under the investing activities section, which lists all such spending. It's important to keep track of this number because it tells you how much money you're putting back into your business, allowing you to better plan for future investments and manage finances more effectively.
