The problem if I understood correctly their previous strife is when you finance patrons across taxation boundaries. If they have to collect vat, they need separate transactions, even if that drived up transaction costd
> If they have to collect vat, they need separate transactions
At least in Europe that's not true. If I buy milk (6% VAT) and beer (19% VAT) in the supermarket here (The Netherlands), I don't have to split that in two transactions.
sure it's true for goods and services if sold to a single state, but if you sell across state boundaries you're required to register and pay your vat to each state where the sale happened and track those transactions along with the source
