Let's understand how charges will be visible for each aggregator and cover a few constraints that the charges might have.

Zomato: 

We can configure multiple types of charges on Zomato.

Here's how a packaging charge of Rs.20 will be visible on Zomato UI.

Swiggy: 

We can only configure item-level charges on Swiggy. For order level charges, the merchant will have to reach out to their POC and get it configured.

Here's how a packaging charge of Rs.15 will be visible on Swiggy's UI.

Swiggy Supports only 2 types of PC:
  1. - Item price -> Percentage
  2. - Per item quantity -> Fixed.
