This library is simply a wrapper around Stripe with easier implementation and some additional primitives (credits / wallets / real-time usage).

So, just as in Stripe, where you would make a new custom plan for, say, an enterprise use, simiarly here, you'd do the same.

Though, I will admit your `billing.config.ts` file will get pretty crowded...

I will think on it and try to come up with a more user-friendly UX for this use case.
