I think I can make this work like this, not sure We can create a custom record “employee discount” and attach that to the project record as a sublist. There users can mark discounts for any employee.  It will contain multiple fields namely • Employee  • Discount Type(Percent/Flat) • Discount Unit  • Discount Description • Project(reference Link) • Duration(Considering the rare occasions as COVID ) ◦ From Date ◦ To Date When creating invoices there will be a UE script deployed on Invoice that will add a custom discount line item “Employee discount ” like below for every employee enabled for discount. The name of the item will be static, but the description can be customized dynamically via script. For exp: 5$ COVID discount for Shweta(can be sourced from the discount description field) The solution will apply to Indian forms only, considering this is a need of Indian Entity only.  The Advance PDF template for this also needs to be customized in order to incorporate this.   The employee discount lines will be proportional to the employees that are enabled for discount and have time entry applied to the current invoice.

What's the problem with this solution?

Have you explored creating an employee (custom) Price Level instead? That way you just drive the item rate via that price level.

Yeah, There are lot of options, if I just had to reduce the price, but the thing is there is also need to show discount line on invoice.

@tuli if you use price level, I think you can still show/add the discount line on the invoice PDF.
