Hello,
In HikaMarket like in HikaShop, you can override/customize every views.
www.hikashop.com/support/documentation/1...-display.html#layout
If you want to display the vendor total, you can retrieve it from the vendor subsale under the "order_vendor_total" field.
But, in case when there are some "adjustments" the value that you will find in the subsale won't be the current one.
That's the main reason why that information is not display currently ; because if you want to be sure that you have the correct vendor total you have to load more data and process it. For most case, the "order_vendor_total" will be correct, but...
About the product listing ; HikaMarket is currently displaying the prices like HikaShop is doing it in the backend.
Displaying the prices with taxes is always user specific. Depending the customer zone the taxes would be different.
So, yes you can change some things in order to force the display with the taxes but it will be regarding the current log user, so about the vendor. It might not be the price that most users will see, or price depending the default tax zone (which is used by guests).
Adding a column for the vendor total in the product listing would require a lot of code.
Because you would need to load all the HikaMarket fee rules and process every prices of each product. And once again, it might not be the accurate display because the product tax and also because the fee rules (regarding the quantity in the cart, the ACL, etc).
Regards,
