Tarsnap goes as low as counting attodollars. Yes, that's 10^-18 dollars, judging by the precision with which individual line items and total account funds are reported. Storage price is 250 picodollars per byte-month.

If it’s not possible to charge such amounts, what exactly is the point of the accuracy?

They're usually charging you for a shitload of them!

Tarsnap is prepaid.

"when it internally converts storage prices from picodollars per month to attodollars per day, it rounds the prices down to benefit the customer."

A gentleman and a scholar.
