Hi
Even though only small, I notice that the GST (Tax) that appears on the order is always lower than the amount that needs to be charged when multiple items are selected.
For example
Item Cost with 10% tax = $8.95
The tax on this amount is 8.95 / 11 = $0.8136 which is near enough 81c which is fine for 1 product.
But when someone orders bulk of an item - say 15 items then the tax amount showing on the invoice is lower than the tax that actually needs to be charged.
Item Cost with tax = $8.95 x 15 = $134.25
Tax on total item cost = $134.25 / 11 = $12.2045 or $12.20 rounded.
In Hika, the tax amount is showing as $12.15.
It is not much - only 5 cents difference but this adds up if hundreds of products are sold. Small hiccup somewhere in the tax calculation.
