mpv are always T9 - becasue they will never incur vat, the invoice they are used on can.
spv - in no_tax t0 and other systems then it depends on the single item being sold thar this can purchase. sales tax would also be t0
should it not be t9, josie definately things t0
spv can be split (part payment) just like MPV

T9 is the correct code for any system that does not have VAT.
mpv are always T9 because VAT is never a consideration at point of sale, it's VAT is calculated upon sale
I am using T9 for non-british systems because then i don't have to invent a new code
spv on VAT systems are defaulted to T1 which is VAT standard rate. This can be changed in the invoice of course and maybe in the future I can add a option to change the default codes and rates.
