That's synonymous with, "It's nothing personal, it's just business."

"If there was any other way" means "if there was an easier way"

It's not always about the money. Take this scenario as an example:

Friend: "We really would like you to come on holiday with us to Fuji"

You: "That's nice of you, but I don't like long haul flights"

Friend: "Don't be a wuzz. It's just one day and you're in paradise"

You: "Yes, but it's still sitting hours cramped in a plane"

Friend: "Is it about the money?"

Now what you really want to say is - 'No, it's not about the money, I just don't want to go on holiday with you to fucking Fuji or anywhere else'

But what you actually say is -

You: "Well it is pretty expensive"

So there we have it, how to try to extricate yourself from an invitation which leaves your friend thinking 'it's all about the money' but it's actually all about him!
