I'm currently working with Vtiger CRM, and I need to modify the way the total for invoices is calculated. Specifically, I want to change the total calculation logic to include some custom business rules.
I've located the Invoice class in modules/Invoice/Invoice.php but i didnt know where to modify
If the calculations are not too complicated, you will probably be able to do it by modifying the templates.
This is the template used to view the quotes/so/po/invoices:
layouts/v7/modules/Inventory/LineItemsDetail.tpl
And this is the template used to edit the quotes/so/po/invoices:
layouts/v7/modules/Inventory/partials/LineItemsContent.tpl
