When a company talks about their bottom line, they're talking about how much money they made after paying for things like wages, supplies, and other expenses. The integrated bottom line is a way of thinking about more than just money when it comes to making decisions for a company.
Imagine you're playing with blocks. You have a bunch of blue blocks and a bunch of red blocks. You want to build a tower. You could just use all of the blue blocks because they're easier to stack, but then you wouldn't have as pretty of a tower. So instead, you decide to use both the blue and red blocks, even though it's a bit harder to stack. This is kind of like the integrated bottom line.
When a company thinks about the integrated bottom line, they're thinking about more than just making money. They're thinking about things like the environment, the people who work for them, and the community around them. They want to use all of these things together, even if it's a bit harder or more expensive, to make a company that's better for everyone.
So just like building a tower with both blue and red blocks might take a bit more effort, thinking about the integrated bottom line might mean a company has to do things like reduce their waste, treat their employees and customers better, or help out their community. But in the end, it makes for a better company that's not just about making money, but also about doing the right thing.
