I did one for the last 5 years of my company, what I charged per foot in USD v. what I would have charged in Sats. It's the first step in, what I hope to be, a base Bitcoin pricing structure. I need this to finally get my books to a regular, double entry accounting. No dollars.

If the customer wants to pay with dollars, they pay an amount equal to the bid amount of bitcoin, hyperinflation be damned.
