Tax inclusive or exclusive

[genny3021]

Hello, I have a custom function, i want to retrieve the accurate shipping cost as will be displayed in the invoice based on if the tax inclusive was checked in the BO. I checked the ps_orders table, i found various values for shipping. Here's what i want my if statement to do:

 

if (price is tax inclusive){

 

retrieve shipping_cost_tax_incl

}

else

{

retrieve shipping_cost_tax_excl

 

}

 

I dont know where the settings for the price is stored in the database so i can select its value.

 

 

Any clue will be appreciated.
