... assuming LSMB is currently the same here as SL. I wonder if the
schema is OK, but the tax calculation is currently too simplistic.
Instead of looking only at the bill-to address...

- Look at an address of us, and the ship-to of the customer. (Which
part of the address: it depends on the country. Like payroll, the rules
vary from one country to the next). If different calculate, if the same
calculate differently. Hmm. it seems the system might need a data
driven tax calculation module, and additional tables to cater for it. I
suppose it would lead to an Enhancement Request like 'Calculate sales
tax based on location dependent rules'
